[PMID: 38777561 DOI: 10.1136/archdischild-2023-326355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Accepted: 04/29/2024] [Indexed: 05/25/2024]
Abstract
OBJECTIVES To investigate prognosis and clinical practices of infants born at 22-23 weeks' gestational age (wkGA) in Japan. DESIGN A national institutional-level electronic questionnaire surveys performed in September 2021. SETTING All perinatal centres across Japan. PATIENTS Infants born at 22-23 wkGA in 2018-2020. MAIN OUTCOME MEASURES Proportion of active resuscitation and survival at neonatal intensive care unit (NICU) discharge, and various clinical practices. RESULTS In total, 255 of 295 NICUs (86%) responded. Among them, 145 took care of infants born at 22-23 wkGA and answered the questions regarding their outcomes and care. In most NICUs (129 of 145 (89%)), infants born at 22+0 wkGA can be actively resuscitated. In almost half of the NICUs (79 of 145 (54%)), infants born at ≥22+0 wkGA were always actively resuscitated. Among 341 and 757 infants born alive at 22 and 23 wkGA, respectively, 85% (291 of 341) and 98% (745 of 757) received active resuscitation after birth. Among infants actively resuscitated at birth, 63% (183 of 291) and 80% (594 of 745) of infants born at 22 and 23 wkGA survived, respectively. The survey revealed unique clinical management for these infants in Japan, including delivery with caul in caesarean section, cut-cord milking after clamping cord, immediate intubation at birth, hydrocortisone use for chronic lung disease, analgesia/sedation use for infants on mechanical ventilation, routine echocardiography and brain ultrasound, probiotics administration, routine glycerin enema and skin dressing to prevent pressure ulcers. CONCLUSIONS Many 22-23 wkGA infants were actively resuscitated in Japan and had a high survival rate. Various unique clinical practices were highlighted.

Predicting severe intraventricular hemorrhage or early death using machine learning algorithms in VLBWI of the Korean Neonatal Network Database. Sci Rep 2024; 14:11113. [PMID: 38750286 PMCID: PMC11096174 DOI: 10.1038/s41598-024-62033-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 05/13/2024] [Indexed: 05/18/2024] Open
Abstract
Severe intraventricular hemorrhage (IVH) in premature infants can lead to serious neurological complications. This retrospective cohort study used the Korean Neonatal Network (KNN) dataset to develop prediction models for severe IVH or early death in very-low-birth-weight infants (VLBWIs) using machine-learning algorithms. The study included VLBWIs registered in the KNN database. The outcome was the diagnosis of IVH Grades 3-4 or death within one week of birth. Predictors were categorized into three groups based on their observed stage during the perinatal period. The dataset was divided into derivation and validation sets at an 8:2 ratio. Models were built using Logistic Regression with Ridge Regulation (LR), Random Forest, and eXtreme Gradient Boosting (XGB). Stage 1 models, based on predictors observed before birth, exhibited similar performance. Stage 2 models, based on predictors observed up to one hour after birth, showed improved performance in all models compared to Stage 1 models. Stage 3 models, based on predictors observed up to one week after birth, showed the best performance, particularly in the XGB model. Its integration into treatment and management protocols can potentially reduce the incidence of permanent brain injury caused by IVH during the early stages of birth.

Neonatal resuscitation program (NRP) guidelines and timing of major resuscitation events in delivery rooms at a level III NICU: Understanding deviations. Resusc Plus 2024; 17:100571. [PMID: 38419829 PMCID: PMC10900917 DOI: 10.1016/j.resplu.2024.100571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 01/18/2024] [Accepted: 01/28/2024] [Indexed: 03/02/2024] Open
Abstract
Objective To describe the timing of major resuscitation events in the Delivery room. Methods A retrospective study of neonates born at a level III birthing hospital who received chest compressions in the delivery room was conducted. The timing of the resuscitation events i.e., intubation, UVC, endotracheal (ETT), epinephrine and intravenous (IV) epinephrine were described. The timing of these events were compared for deliveries with the presence of neonatology team. Results 51 neonates were included. The primary outcome occurred in 28 (65%) of deliveries. An alternate airway was secured at 4.24 ± 5.9 minutes. Endotracheal epinephrine and IV epinephrine were administered at a mean time of 3.98 ± 3 minutes and 10.87± 5.18 minutes after the initiation of chest compressions respectively. Conclusion Data from real-life cases on the timeline of events suggest that major resuscitation events as suggested by Neonatal Resuscitation Program Guidelines, are often significantly delayed.

[PMID: 38398420 PMCID: PMC10889373 DOI: 10.3390/jcm13041103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 02/06/2024] [Accepted: 02/11/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Adequate perinatal management is essential in caring for extremely preterm (EP) infants. We aimed to evaluate and compare the impact of different protocols on short-term outcomes. METHODS A retrospective study was conducted on EP infants in a Romanian perinatal tertiary center during 2008-2012 and 2018-2022. RESULTS Data on 270 EP infants (121 in period I, 149 in period II) were analyzed collectively and stratified into two subgroups by gestational age. Initial FiO2 administration (100% vs. 40%% p < 0.001), lung recruitment at birth (19.0% vs. 55.7% p < 0.001), early rescue surfactant administration (34.7% vs. 65.8%; p < 0.001), and the mechanical ventilation rate (98.3% vs. 58.4%; p < 0.001) were significantly improved during period II. Survival rates of EP infants significantly improved from 41.3% to 72.5%, particularly in the 26-28 weeks subgroup (63.8% to 83%). Compared to period I, the overall frequency of severe IVH decreased in period II from 30.6% to 14.1%; also, BPD rates were lower (36.6% vs. 23.4%; p = 0.045) in the 26-28 weeks subgroup. Despite improvements, there were no significant differences in the frequencies of NEC, sepsis, PVL, ROP, or PDA. CONCLUSIONS Implementing evidence-based clinical guidelines can improve short-term outcomes.

What is the Opinion of the Health Care Personnel Regarding the Use of Different Assistive Tools to Improve the Quality of Neonatal Resuscitation? Am J Perinatol 2024. [PMID: 38190977 DOI: 10.1055/a-2240-2094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/10/2024]
Abstract
OBJECTIVE It is important to determine whether the use of different quality improvement tools in neonatal resuscitation is well-received by health care teams and improves coordination and perceived quality of the stabilization of the newborn at birth. This study aimed to explore the satisfaction of personnel involved in resuscitation for infants under 32 weeks of gestational age (<32 wGA) at birth with the use of an assistance toolkit: Random Real-time Safety Audits (RRSA) of neonatal stabilization stations, the use of pre-resuscitation checklists, and the implementation of briefings and debriefings. STUDY DESIGN A quasi-experimental, prospective, multicenter intervention study was conducted in five level III-A neonatal intensive care units in Madrid (Spain). The intervention involved conducting weekly RRSA of neonatal resuscitation stations and the systematic use of checklists, briefings, and debriefings during stabilization at birth for infants <32 wGA. The satisfaction with their use was analyzed through surveys conducted with the personnel responsible for resuscitating these newborns. These surveys were conducted both before and after the intervention phase (each lasting 1 year) and used a Likert scale response model to assess various aspects of the utility of the introduced assistance tools, team coordination, and perceived quality of the resuscitation. RESULTS Comparison of data from 200 preintervention surveys and 155 postintervention surveys revealed statistically significant differences (p < 0.001) between the two phases. The postintervention phase scored higher in all aspects related to the effective utilization of these tools. Improvements were observed in team coordination and the perceived quality of neonatal resuscitation. These improved scores were consistent across personnel roles and years of experience. CONCLUSION Personnel attending to infants <32 wGA in the delivery room are satisfied with the application of RRSA, checklists, briefings, and debriefings in the neonatal resuscitation and perceive a higher level of quality in the stabilization of these newborns following the introduction of these tools. KEY POINTS · RRSA, checklists, briefings, and debriefings improve the quality of neonatal resuscitation at birth.. · These tools, when used together, are well-received and enhance perceived resuscitation quality.. · Perception of utility and quality improvement is consistent across roles and experience..

The vocal cords are predominantly closed in preterm infants <30 weeks gestation during transition after birth; an observational study. Resuscitation 2024; 194:110053. [PMID: 37979668 DOI: 10.1016/j.resuscitation.2023.110053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 11/06/2023] [Accepted: 11/12/2023] [Indexed: 11/20/2023]
Abstract
AIM Studies in animals have shown that vocal cords (VCs) close during apnoea before and after birth, thereby impairing the effect of non-invasive ventilation. We tested the feasibility of visualising VCs using ultrasonography (US) and investigated the position and movement of the VCs during non-invasive respiratory support of preterm infants at birth. METHODS In an observational study, VCs were visualised using US in infants <30 weeks gestation during both stabilisation after birth and at one hour after birth. Respiratory efforts were simultaneously recorded. The percentage of time the VCs were closed in the first ten minutes was determined from videoframes acquired at 15 Hz and compared with respiratory flow patterns measured using a respiratory function monitor. RESULTS US of the VCs could be performed in 20/20 infants included (median (IQR) gestational age 27+6 (27+1-28+6) weeks) without interfering with stabilisation, of whom 60% (12/20) were initially breathing and 40% (8/20) were apnoeic at birth. In breathing infants, the VCs closed between breaths and during breath holds, which accounted for 57% (49-66) of the time. In apnoeic infants receiving positive pressure ventilation, the VCs were closed for 93% (81-99) of the time. US at one hour after birth could be performed in 14/20 infants, VCs were closed between breaths and during breath holds, accounting for 46% (27-52) of the time. CONCLUSION Visualising VCs in preterm infants at birth using US is feasible. The VCs were closed during apnoea, in between breaths and during breath holds, impairing the effect of ventilation given.

Delivery room resuscitation intensity and associated neonatal outcomes of 24 +0-31 +6 weeks' preterm infants in China: a retrospective cross-sectional study. World J Pediatr 2024; 20:64-72. [PMID: 37389785 PMCID: PMC10827838 DOI: 10.1007/s12519-023-00738-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 06/01/2023] [Indexed: 07/01/2023]
Abstract
BACKGROUND The aim of this study was to review current delivery room (DR) resuscitation intensity in Chinese tertiary neonatal intensive care units and to investigate the association between DR resuscitation intensity and short-term outcomes in preterm infants born at 24+0-31+6 weeks' gestation age (GA). METHODS This was a retrospective cross-sectional study. The source population was infants born at 24+0-31+6 weeks' GA who were enrolled in the Chinese Neonatal Network 2019 cohort. Eligible infants were categorized into five groups: (1) regular care; (2) oxygen supplementation and/or continuous positive airway pressure (O2/CPAP); (3) mask ventilation; (4) endotracheal intubation; and (5) cardiopulmonary resuscitation (CPR). The association between DR resuscitation and short-term outcomes was evaluated by inverse propensity score-weighted logistic regression. RESULTS Of 7939 infants included in this cohort, 2419 (30.5%) received regular care, 1994 (25.1%) received O2/CPAP, 1436 (18.1%) received mask ventilation, 1769 (22.3%) received endotracheal intubation, and 321 (4.0%) received CPR in the DR. Advanced maternal age and maternal hypertension correlated with a higher need for resuscitation, and antenatal steroid use tended to be associated with a lower need for resuscitation (P < 0.001). Severe brain impairment increased significantly with increasing amounts of resuscitation in DR after adjusting for perinatal factors. Resuscitation strategies vary widely between centers, with over 50% of preterm infants in eight centers requiring higher intensity resuscitation. CONCLUSIONS Increased intensity of DR interventions was associated with increased mortality and morbidities in very preterm infants in China. There is wide variation in resuscitative approaches across delivery centers, and ongoing quality improvement to standardize resuscitation practices is needed.

Abstract
BACKGROUND Newborn hypothermia at birth remains as global challenge across all settings. The prevention of delivery room hypothermia at birth could potentially reduce neonatal morbidity and mortality. OBJECTIVE To compare the heat conservation efficacy of Neohelp and Neowrap and evaluate the heat production efficacy of trans-warmer infant mattress (TWM) in a laboratory setting. METHODS A beaker of water was heated at 60∘C was covered by Neohelp or two layers of Neowrap and left to cool in an open room for 90 minutes and calculated the decay constant. Using infra-red camera, we measured the maximum temperature and time taken to reach the temperature in the TWM. RESULTS Neowrap took 863 seconds for the temperature to drop from 37∘C to 35∘C, compared with 941 seconds with Neohelp. When activated TWM reached a maximum temperature of 39.3 ± 0.1∘C. It took 30 seconds when the activator was placed in the centre, compared with 88 seconds when it was at the corner. CONCLUSION Compared to Neowrap, Neohelp had better heat conservation properties. Activating the metal disk from the TWM center would deliver quicker heat.

Unveiling pseudo-pulseless electrical activity (pseudo-PEA) in ultrasound-integrated infant resuscitation. Eur J Pediatr 2023; 182:5285-5291. [PMID: 37725211 PMCID: PMC10746595 DOI: 10.1007/s00431-023-05199-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/04/2023] [Accepted: 09/06/2023] [Indexed: 09/21/2023]
Abstract
Point-of-care ultrasound (POCUS) holds immense potential to manage critically deteriorating infants within the neonatal intensive care unit (NICU) and is increasingly used in neonatal clinical practice worldwide. Recent ultrasound-based protocols such as the Sonographic Assessment of liFe-threatening Emergencies-Revised (SAFE-R) and Crashing Neonate Protocol (CNP) offer step-by-step guidance for diagnosing and addressing reversible causes of cardiorespiratory collapse. Traditionally, pulseless electrical activity (PEA) has been diagnosed solely based on absent pulses on clinical examination, disregarding myocardial activity. However, integrating POCUS into resuscitation unveils the concept of pseudo-PEA, where cardiac motion activity is observed visually on the ultrasound but fails to generate a detectable pulse due to inadequate cardiac output. Paradoxically, existing neonatal resuscitation protocols lack directives for identifying and effectively leveraging pseudo-PEA insights in infants, limiting their potential to enhance outcomes. Pseudo-PEA is extensively described in adult literature owing to routine POCUS use in resuscitation. This review article comprehensively evaluates the adult pseudo-PEA literature to glean insights adaptable to neonatal care. Additionally, we propose a simple strategy to integrate POCUS during neonatal resuscitation, especially in infants who do not respond to routine measures. CONCLUSION Pseudo-PDA is a newly recognized diagnosis in infants with the use of POCUS during resuscitation. This article highlights the importance of cross-disciplinary learning in tackling emerging challenges within neonatal medicine. WHAT IS KNOWN • Point-of-Care ultrasound (POCUS) benefits adult cardiac arrest management, particularly in distinguishing true Pulseless Electrical Activity (PEA) from pseudo-PEA. • Pseudo-PEA is when myocardial motion can be seen on ultrasound but fails to generate palpable pulses or sustain circulation despite evident cardiac electrical activity. WHAT IS NEW • Discuss recognition and management of pseudo-PEA in infants. • A proposed algorithm to integrate POCUS into active neonatal cardiopulmonary resuscitation (CPR) procedures.

Abstract
AIM This scoping review identified studies on approaches to intact cord resuscitation and/or stabilisation (ICR/S) for neonates delivered by Caesarean section (C-section). METHODS A systematic literature search was carried out using the PubMed, Web of Science, Scopus, Cochrane and CINAHL databases to identify papers published in English from inception to 14 November 2022. RESULTS We assessed 2613 studies and included 18 from 10 countries, covering 1-125 C-sections: the United States, the United Kingdom, Australia, India, Italy, China, France, The Netherlands, New Zealand and Taiwan. The papers were published from 2014 to 2023, and the majority were randomised controlled trials and observational studies. Different platforms, equipment and staff positions in relation to the operating table were described. Options for resuscitation and stabilisation included different bedding and trolley approaches, and maintaining aseptic conditions was mainly addressed by the neonatal team scrubbing in. Hypothermia was prevented by using warm surfaces, polythene bags and radiant heaters. Equipment was kept easily accessible by mounting it on a trolley or a separate mobile pole. CONCLUSION We could not reach definitive conclusions on the optimal method for performing ICR/S during a C-section, due to study variations. However, a number of equipment and management options appeared to be feasible approaches.

T-Piece resuscitator versus self-inflating bag for delivery room resuscitation in preterm neonates: a randomized controlled trial. Eur J Pediatr 2023; 182:5565-5576. [PMID: 37792092 DOI: 10.1007/s00431-023-05230-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/15/2023] [Accepted: 09/18/2023] [Indexed: 10/05/2023]
Abstract
The establishment of adequate ventilation is the cornerstone of neonatal resuscitation in the delivery room (DR). This parallel-group, accessor-blinded randomized controlled trial compared the changes in peripheral oxygen saturation (SpO2), heart rate (HR), and cerebral regional oxygen saturation (crSO2) with the use of a T-piece resuscitator (TPR) versus self-inflating bag (SIB) as a mode of providing positive pressure ventilation (PPV) during DR resuscitation in preterm neonates. Seventy-two preterm neonates were randomly allocated to receive PPV with TPR (n = 36) or SIB (n = 36). The primary outcome was SpO2 (%) at 5 min. The secondary outcomes included the time to achieve a SpO2 ≥ 80% and > 85%, HR > 100/min, fractional-inspired oxygen (FiO2) requirement, minute-specific SpO2, HR and FiO2 trends for the first 5 min of life, need for DR-intubation, crSO2, need and duration of respiratory support, and other in-hospital morbidities. Mean SpO2 at 5 min was 74.5 ± 17.8% and 69.4 ± 22.4%, in TPR and SIB groups, respectively [Mean difference, 95% Confidence Interval 5.08 (-4.41, 14.58); p = 0.289]. No difference was observed in the time to achieve a SpO2 ≥ 80% and > 85%, HR > 100/min, the requirement of FiO2, DR-intubation, and the need and duration of respiratory support. There was no significant difference in the minute-specific SpO2, HR, and FiO2 requirements for the first 5 min. CrSO2 (%) at one hour was lower by 5% in the TPR group compared to SIB; p = 0.03. Other complications were comparable. CONCLUSIONS TPR and SIB resulted in comparable SpO2 at 5 min along with similar minute-specific SpO2, HR, and FiO2 trends. CLINICAL TRIAL REGISTRATION Clinical trial registry of India, Registration no: CTRI/2021/10/037384, Registered prospectively on: 20/10/2021, https://ctri.icmr.org.in/ . WHAT IS KNOWN • Compared to self-inflating bags (SIB), T-piece resuscitators (TPR) provide more consistent inflation pressure and tidal volume as shown in animal and bench studies. • There is no strong recommendation for one device over the other in view of low certainty evidence. WHAT IS NEW • TPR and SIB resulted in comparable peripheral oxygen saturation (SpO2) at 5 min along with similar minute-specific SpO2, heart rate, and fractional-inspired oxygen requirement trends. • Short-term complications and mortality rates were comparable with both devices.

Abstract
OBJECTIVES To determine efficacy of non-invasive positive pressure face mask ventilation using a ventilator device (NIPPmV) for achieving early effective ventilation compared to that by self-inflating bag (SIB) or T- piece resuscitator (TPR). METHODS The authors video recorded 33 trained resuscitators using NIPPmV (provided using ventilator device), SIB [a 500 ml silicone SIB without a positive end expiratory pressure (PEEP) valve] and a TPR. Using a continuous pressure recording system and a neonatal manikin, the authors evaluated the efficacy of the ventilation to achieve early effective ventilation during 30 s of ventilation. The primary outcome was time to achieve effective chest rise. Secondary outcomes were peak inspiratory pressure (PIP), ventilation rate and the need to perform ventilation corrective steps during positive pressure ventilation (PPV) among the devices. RESULTS Total 99 videos were recorded. The time(s) taken to achieve the first chest rise was significantly lesser in NIPPmV group compared to SIB and TPR (3.0 ± 1.7 vs. 3.7 ± 1.9 vs. 7.5 ± 5.4, respectively, p <0.001). The mean PIP delivered by NIPPmV compared to SIB & TPR (19.8 ± 1.6 vs. 35.6 ± 7.4 vs. 17.8 ± 2.0 cm H20 respectively; p <0.001) was more accurate with preset PIP. Ventilation, in terms of breath rate, was observed to be controlled more accurately with NIPPmV compared to SIB & TPR (50 vs. 42 vs. 33 per min respectively; p <0.001). CONCLUSIONS The non-invasive positive pressure face mask ventilation using a ventilator (NIPPmV) resulted in achieving early, effective and consistent ventilation.

Abstract
OBJECTIVE Lung ultrasound score (LUS) accurately guides surfactant replacement in preterm neonates with respiratory distress syndrome due to surfactant deficiency. However, surfactant deficiency is not the unique pathobiological feature, as there may be relevant lung inflammation, such as in certain cases of clinical chorioamnionitis (CC). We aim to investigate if CC influences LUS and ultrasound-guided surfactant treatment. DESIGN Retrospective (2017-2022), large, cohort study targeted to recruit a homogeneous population treated with unchanged respiratory care policy and lung ultrasound protocol. Patients with (CC+: 207) and without (CC-: 205) chorioamnionitis were analyzed with propensity score matching and subsequent additional multivariate adjustments. RESULTS LUS was identical at unmatched and matched comparisons. Consistently, at least one surfactant dose was given in 98 (47.3%) and 83 (40.5%) neonates in the CC+ and CC- matched cohorts, respectively (p = .210). Multiple doses were needed in 28 (13.5%) and 21 (10.2%) neonates in the CC+ and CC- cohorts, respectively (p = .373). Postnatal age at surfactant dosing was also similar. LUS was higher in patients who were diagnosed with neonatal acute respiratory distress syndrome (NARDS) (CC+ cohort: 10.3 (2.9), CC- cohort: 11.4 (2.6)), than in those without NARDS (CC+ cohort: 6.1 (3.7), CC- cohort: 6.2 (3.9); p < .001, for both). Surfactant use was more frequent in neonates with, than in those without NARDS (p < .001). Multivariate adjustments confirmed NARDS as the variable with greater effect size on LUS. CONCLUSIONS CC does not influence LUS in preterm neonates, unless inflammation is enough severe to trigger NARDS. The occurrence of NARDS is key factor influencing the LUS.

Background Neonatal resuscitation is an important skillset for clinicians attending deliveries. Accredited neonatal resuscitation training is not obligatory in most training centers of standardized medical residency programs before 2022 in China. We investigated the feasibility and effectiveness of neonatal resuscitation simulation training (neo-RST) in residents in Shenzhen, China. Methods Four two-day neo-RST workshops were conducted in the University of Hong Kong-Shenzhen Hospital and Shenzhen Health Capacity Building and Continuing Education Center in 2020-2021. The workshops had Neonatal Resuscitation Program (NRP)® update, skill stations and simulation practice with debriefing. Each participant had the integrated skill station assessment (ISSA) at the end of workshop. Participants of workshops included residents of different disciplines and health care providers (HCPs) of neonatal and obstetrical departments. We compared demographic characteristics, neonatal resuscitation knowledge before training, ISSA overall and categorical scores on skill sets between residents and HCPs. Results In 2020-2021, 4 neo-RST workshops were conducted with 48 residents and 48 HCPs. The residents group had less working experience, less prior experience in neo-RST and lower neonatal resuscitation knowledge scores than those of HCPs group. After the workshop, residents had higher overall ISSA score than that of HCPs group (90.2 ± 5.9 vs. 86.3 ± 6.6%, P = 0.003, respectively). There was no significant difference in the numbers of participants scored <80% in residents and HCPs group (3 [6.3%] vs. 7 [14.6%], respectively). Regarding the categorical scores, residents scored significantly higher in preparation, ventilation, crisis resource management and behavioral skills but lower in appropriate oxygen use, when compared with the HCPs. Conclusion Neo-RST for residents is feasible with promising short-term educational outcomes. Neo-RST could be implemented in standardized medical residency programs in China.

Effects of umbilical cord milking versus delayed cord clamping on systemic blood flow in intrauterine growth-restricted neonates: A randomized controlled trial. Eur J Pediatr 2023; 182:4185-4194. [PMID: 37439849 DOI: 10.1007/s00431-023-05105-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 06/26/2023] [Accepted: 07/06/2023] [Indexed: 07/14/2023]
Abstract
Recommendations for umbilical cord management in intrauterine growth-restricted (IUGR) neonates are lacking. The present randomized controlled trial compared hemodynamic effects of umbilical cord milking (UCM) with delayed cord clamping (DCC) in IUGR neonates > 28 weeks of gestation, not requiring resuscitation. One hundred seventy IUGR neonates were randomly allocated to intact UCM (4 times squeezing of 20 cm intact cord; n = 85) or DCC (cord clamping after 60 s; n = 85) immediately after delivery. The primary outcome variable was superior vena cava (SVC) blood flow at 24 ± 2 h. Secondary outcomes assessed were anterior cerebral artery (ACA) and superior mesenteric artery (SMA) blood flow indices, right ventricular output (RVO), regional cerebral oxygen saturation (CrSO2) and venous hematocrit at 24 ± 2 h, peak total serum bilirubin (TSB), incidences of in-hospital complications, need and duration of respiratory support, and hospital stay. SVC flow was significantly higher in UCM compared to DCC (111.95 ± 33.54 and 99.49 ± 31.96 mL/kg/min, in UCM and DCC groups, respectively; p < 0.05). RVO and ACA/SMA blood flow indices were comparable whereas CrSO2 was significantly higher in UCM group. Incidences of polycythemia and jaundice requiring phototherapy were similar despite significantly higher venous hematocrit and peak TSB in UCM group. The need for non-invasive respiratory support was significantly higher in UCM group though the need and duration of mechanical ventilation and other outcomes were comparable. CONCLUSIONS UCM significantly increases SVC flow, venous hematocrit, and CrSO2 compared to DCC in IUGR neonates without any difference in other hemodynamic parameters and incidences of polycythemia and jaundice requiring phototherapy; however, the need for non-invasive respiratory support was higher with UCM. TRIAL REGISTRATION Clinical trial registry of India (CTRI/2021/03/031864). WHAT IS KNOWN • Umbilical cord milking (UCM) increases superior vena cava blood flow (SVC flow) and hematocrit without increasing the risk of symptomatic polycythemia and jaundice requiring phototherapy in preterm neonates compared to delayed cord clamping (DCC). • An association between UCM and intraventricular hemorrhage in preterm neonates < 28 weeks of gestation is still being investigated. WHAT IS NEW • Placental transfusion by UCM compared to DCC increases SVC flow, regional cerebral oxygenation, and hematocrit without increasing the incidence of symptomatic polycythemia and jaundice requiring phototherapy in intrauterine growth-restricted neonates. • UCM also increases the need for non-invasive respiratory support compared to DCC.

Characteristics, Genetic Testing, and Diagnoses of Infants with Neonatal Encephalopathy Not Due to Hypoxic Ischemic Encephalopathy: A Cohort Study. J Pediatr 2023; 260:113533. [PMID: 37269901 DOI: 10.1016/j.jpeds.2023.113533] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 04/29/2023] [Accepted: 05/30/2023] [Indexed: 06/05/2023]
Abstract
OBJECTIVE To characterize the presentation and evaluation of infants with neonatal encephalopathy (NE) not due to hypoxic-ischemic encephalopathy (non-HIE NE) and to describe the genetic abnormalities identified. STUDY DESIGN Retrospective cohort study of 193 non-HIE NE neonates admitted to a level IV NICU from 2015 through 2019. For changes in testing over time, Cochrane-Armitage test for trend was used with a Bonferroni-corrected P-value, and comparison between groups was performed using Fisher exact test. RESULT The most common symptom of non-HIE NE was abnormal tone in 47% (90/193). Ten percent (19/193) died prior to discharge, and 48% of survivors (83/174) required medical equipment at discharge. Forty percent (77/193) underwent genetic testing as an inpatient. Of 52 chromosomal studies, 54 targeted tests, and 16 exome sequences, 10%, 41%, and 69% were diagnostic, respectively, with no difference in diagnostic rates between infants with and without an associated congenital anomaly and/or dysmorphic feature. Twenty-eight genetic diagnoses were identified. CONCLUSIONS Neonates with non-HIE NE have high rates of morbidity and mortality and may benefit from early genetic testing, even in the absence of other exam findings. This study broadens our knowledge of genetic conditions underlying non-HIE NE, which may enable families and care teams to anticipate the needs of the individual, allow early initiation of targeted therapies, and facilitate decisions surrounding goals of care.

Ultrasound-assessed lung aeration, oxygenation and respiratory care in neonatal bile acid pneumonia: A nested case-control study. Acta Paediatr 2023; 112:1898-1904. [PMID: 37265415 DOI: 10.1111/apa.16865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 05/30/2023] [Accepted: 06/01/2023] [Indexed: 06/03/2023]
Abstract
AIM Neonatal bile acid pneumonia (NBAP) occurs in neonates following obstetric cholestasis. We aimed to study the lung aeration and respiratory support of NBAP. METHODS Nested, case/control study enrolling age-matched neonates with NBAP, respiratory distress syndrome (RDS) or transient tachypnoea (TTN). Lung aeration and oxygenation were assessed with lung ultrasound score, oxygenation index and SpO2 /FiO2 . RESULTS Nineteen, 22 and 25 neonates with NBAP, RDS and TTN, respectively were studied (mean gestational age = 33 (2.2) weeks, 30 (45.5%) males). Upon admission, RDS patients had the worst lung ultrasound score (p = 0.022) and oxygenation index (p = 0.001), while NBAP and TTN neonates had similar values. At the worst time-point, NBAP and RDS patients showed similar oxygenation index (NBAP: 4.6 [2], RDS: 5.7 [3]) and SpO2 /FiO2 (NBAP: 3.1 [1.1], RDS: 2.7 [1]) which were worse than those of TTN patients (oxygenation index: p = 0.015, SpO2 /FiO2 : p = 0.001). RDS neonates needed the longest continuous positive airway pressure and highest mean airway pressure, but NBAP neonates needed invasive ventilation (26.3%, p = 0.01) and surfactant (31.6%, p = 0.003) more often than TTN patients who never needed these. CONCLUSION NBAP was a mild disorder in the first hours of life but subsequently worsened and became similar to RDS.

Variation in delivery room management of preterm infants across Europe: a survey of the Union of European Neonatal and Perinatal Societies. Eur J Pediatr 2023; 182:4173-4183. [PMID: 37436521 DOI: 10.1007/s00431-023-05107-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Revised: 07/04/2023] [Accepted: 07/06/2023] [Indexed: 07/13/2023]
Abstract
The aim of the present study, endorsed by the Union of European Neonatal and Perinatal Societies (UENPS) and the Italian Society of Neonatology (SIN), was to analyze the current delivery room (DR) stabilization practices in a large sample of European birth centers that care for preterm infants with gestational age (GA) < 33 weeks. Cross-sectional electronic survey was used in this study. A questionnaire focusing on the current DR practices for infants < 33 weeks' GA, divided in 6 neonatal resuscitation domains, was individually sent to the directors of European neonatal facilities, made available as a web-based link. A comparison was made between hospitals grouped into 5 geographical areas (Eastern Europe (EE), Italy (ITA), Mediterranean countries (MC), Turkey (TUR), and Western Europe (WE)) and between high- and low-volume units across Europe. Two hundred and sixty-two centers from 33 European countries responded to the survey. At the time of the survey, approximately 20,000 very low birth weight (VLBW, < 1500 g) infants were admitted to the participating hospitals, with a median (IQR) of 48 (27-89) infants per center per year. Significant differences between the 5 geographical areas concerned: the volume of neonatal care, ranging from 86 (53-206) admitted VLBW infants per center per year in TUR to 35 (IQR 25-53) in MC; the umbilical cord (UC) management, being the delayed cord clamping performed in < 50% of centers in EE, ITA, and MC, and the cord milking the preferred strategy in TUR; the spotty use of some body temperature control strategies, including thermal mattress mainly employed in WE, and heated humidified gases for ventilation seldom available in MC; and some of the ventilation practices, mainly in regard to the initial FiO2 for < 28 weeks' GA infants, pressures selected for ventilation, and the preferred interface to start ventilation. Specifically, 62.5% of TUR centers indicated the short binasal prongs as the preferred interface, as opposed to the face mask which is widely adopted as first choice in > 80% of the rest of the responding units; the DR surfactant administration, which ranges from 44.4% of the birth centers in MC to 87.5% in WE; and, finally, the ethical issues around the minimal GA limit to provide full resuscitation, ranging from 22 to 25 weeks across Europe. A comparison between high- and low-volume units showed significant differences in the domains of UC management and ventilation practices. Conclusion: Current DR practice and ethical choices show similarities and divergences across Europe. Some areas of assistance, like UC management and DR ventilation strategies, would benefit of standardization. Clinicians and stakeholders should consider this information when allocating resources and planning European perinatal programs. What is Known: • Delivery room (DR) support of preterm infants has a direct influence on both immediate survival and long-term morbidity. • Resuscitation practices for preterm infants often deviate from the internationally defined algorithms. What is New: • Current DR practice and ethical choices show similarities and divergences across Europe. Some areas of assistance, like UC management and DR ventilation strategies, would benefit of standardization. • Clinicians and stakeholders should consider this information when allocating resources and planning European perinatal programs.

Abstract
BACKGROUND Cardiopulmonary resuscitation and subsequent care are subject to various ethical and legal issues. Few studies have addressed ethical and legal issues in post-resuscitation care. OBJECTIVE To explore nurses' experiences of ethical and legal issues in post-resuscitation care. RESEARCH DESIGN This qualitative study adopted an exploratory descriptive qualitative design using conventional content analysis. PARTICIPANTS AND RESEARCH CONTEXT In-depth, semi-structured interviews were conducted in three educational hospital centers in northwestern Iran. Using purposive sampling, 17 nurses participated. Data were analyzed by conventional content analysis. ETHICAL CONSIDERATIONS The study was approved by Research Ethics Committees at Tabriz University of Medical Sciences. Participation was voluntary and written informed consent was obtained. For each interview, the ethical principles including data confidentiality and social distance were respected. FINDINGS Five main categories emerged: Pressure to provide unprincipled care, unprofessional interactions, ignoring the patient, falsifying documents, and specific ethical challenges. Pressures in the post-resuscitation period can cause nurses to provide care that is not consistent with guidelines, and to avoid communicating with physicians, patients and their families. Patients can also be labeled negatively, with early judgments made about their condition. Medical records can be written in a way to indicate that all necessary care has been provided. Disclosure, withdrawing, and withholding of therapy were also specific important ethical challenges in the field of post-resuscitation care. CONCLUSION There are many ethical and legal issues in post-resuscitation care. Developing evidence-based guidelines and training staff to provide ethical care can help to reduce these challenges.

Abstract
OBJECTIVE To compare HR pattern of vigorous newborns during the first 180 s with early (≤60 s, ECC) or delayed (>60 s, DCC) cord clamping. STUDY DESIGN Observational study including dry-electrode ECG monitoring of 610 vaginally-born singleton term and late-preterm (≥34 weeks) who were vigorous after birth. RESULTS 198 received ECC while 412 received DCC with median cord clamping at 37 s and 94 s. Median HR remained stable from 30 to 180 s with DCC (172 and 170 bpm respectively) but increased with ECC (169 and 184 bpm). The proportion with bradycardia was higher among ECC than DCC at 30 s and fell faster in the DCC through 60 s. After adjusting for factors affecting timing of cord clamping, ECC had significant risk of bradycardia compared to DCC (aRR 1.51; 95% CI; 1.01-2.26). CONCLUSION Early heart instability and higher risk of bradycardia with ECC as compared to DCC supports the recommended clinical practice of DCC.

BORN study: a multicenter randomized trial investigating cord blood red blood cell transfusions to reduce the severity of retinopathy of prematurity in extremely low gestational age neonates. Trials 2022; 23:1010. [PMID: 36514106 PMCID: PMC9746198 DOI: 10.1186/s13063-022-06949-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Accepted: 11/22/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Extremely low gestational age neonates (ELGANs, i.e., neonates born before 28 weeks of gestation) are at high risk of developing retinopathy of prematurity (ROP), with potential long-life visual impairment. Due to concomitant anemia, ELGANs need repeated red blood cell (RBC) transfusions. These produce a progressive replacement of fetal hemoglobin (HbF) by adult hemoglobin (HbA). Furthermore, a close association exists between low levels of HbF and severe ROP, suggesting that a perturbation of the HbF-mediated oxygen release may derange retinal angiogenesis and promote ROP. METHODS/DESIGN BORN (umBilical blOod to tRansfuse preterm Neonates) is a multicenter double-blinded randomized controlled trial in ELGANs, to assess the effect of allogeneic cord blood RBC transfusions (CB-RBCs) on severe ROP development. Recruitment, consent, and randomization take place at 10 neonatology intensive care units (NICUs) of 8 Italian tertiary hospitals. ELGANs with gestational age at birth comprised between 24+0 and 27+6 weeks are randomly allocated into two groups: (1) standard RBC transfusions (adult-RBCs) (control arm) and (2) CB-RBCs (intervention arm). In case of transfusion need, enrolled patients receive transfusions according to the allocation arm, unless an ABO/RhD CB-RBC is unavailable. Nine Italian public CB banks cooperate to make available a suitable amount of CB-RBC units for all participating NICUs. The primary outcome is the incidence of severe ROP (stage 3 or higher) at discharge or 40 weeks of postmenstrual age, which occurs first. DISCUSSION BORN is a groundbreaking trial, pioneering a new transfusion approach dedicated to ELGANs at high risk for severe ROP. In previous non-randomized trials, this transfusion approach was proven feasible and able to prevent the HbF decrease in patients requiring multiple transfusions. Should the BORN trial confirm the efficacy of CB-RBCs in reducing ROP severity, this transfusion strategy would become the preferential blood product to be used in severely preterm neonates.

Abstract
OBJECTIVE Inadequate adherence to resuscitation for non-crying infants will have poor outcome and thus rationalise a need for real-time guidance and quality improvement technology. This study assessed the usability, feasibility and acceptability of a novel technology of real-time visual guidance, with sound and video recording during resuscitation. SETTING A public hospital in Nepal. DESIGN A cross-sectional design. INTERVENTION The technology has an infant warmer with light, equipped with a tablet monitor, NeoBeat and upright bag and mask. The tablet records resuscitation activities, ventilation sound, heart rate and display time since birth. Healthcare providers (HCPs) were trained on the technology before piloting. DATA COLLECTION AND ANALYSIS HCPs who had at least 8 weeks of experience using the technology completed a questionnaire on usability, feasibility and acceptability (ranged 1-5 scale). Overall usability score was calculated (ranged 1-100 scale). RESULTS Among the 30 HCPs, 25 consented to the study. The usability score was good with the mean score (SD) of 68.4% (10.4). In terms of feasibility, the participants perceived that they did not receive adequate support from the hospital administration for use of the technology, mean score (SD) of 2.44 (1.56). In terms of acceptability, the information provided in the monitor, that is, time elapsed from birth was easy to understand with mean score (SD) of 4.60 (0.76). CONCLUSION The study demonstrates reasonable usability, feasibility and acceptability of a technological solution that records audio visual events during resuscitation and provides visual guidance to improve care.

A Randomized, Controlled Animal Study: 21% or 100% Oxygen during Cardiopulmonary Resuscitation in Asphyxiated Infant Piglets. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9111601. [PMID: 36360329 PMCID: PMC9688656 DOI: 10.3390/children9111601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/17/2022] [Accepted: 10/19/2022] [Indexed: 01/25/2023]
Abstract
Background: During pediatric cardiopulmonary resuscitation (CPR), resuscitation guidelines recommend 100% oxygen (O2); however, the most effective O2 concentration for infants unknown. Aim: We aimed to determine if 21% O2 during CPR with either chest compression (CC) during sustained inflation (SI) (CC + SI) or continuous chest compression with asynchronized ventilation (CCaV) will reduce time to return of spontaneous circulation (ROSC) compared to 100% O2 in infant piglets with asphyxia-induced cardiac arrest. Methods: Piglets (20−23 days of age, weighing 6.2−10.2 kg) were anesthetized, intubated, instrumented, and exposed to asphyxia. Cardiac arrest was defined as mean arterial blood pressure < 25 mmHg with bradycardia. After cardiac arrest, piglets were randomized to CC + SI or CCaV with either 21% or 100% O2 or the sham. Heart rate, arterial blood pressure, carotid blood flow, and respiratory parameters were continuously recorded. Main results: Baseline parameters, duration, and degree of asphyxiation were not different. Median (interquartile range) time to ROSC was 107 (90−440) and 140 (105−200) s with CC + SI 21% and 100% O2, and 600 (50−600) and 600 (95−600) s with CCaV 21% and 100% O2 (p = 0.27). Overall, six (86%) and six (86%) piglets with CC + SI 21% and 100% O2, and three (43%) and three (43%) piglets achieved ROSC with CCaV 21% and 100% O2 (p = 0.13). Conclusions: In infant piglets resuscitated with CC + SI, time to ROSC reduced and survival improved compared to CCaV. The use of 21% O2 had similar time to ROSC, short-term survival, and hemodynamic recovery compared to 100% oxygen. Clinical studies comparing 21% with 100% O2 during infant CPR are warranted.

Abstract
OBJECTIVE We sought to determine the effect of stimulation during positive pressure ventilation (PPV) on the number of spontaneous breaths, exhaled tidal volume (VTe), mask leak and obstruction. DESIGN Secondary analysis of a prospective, randomised trial comparing two face masks. SETTING Single-centre delivery room study. PATIENTS Newborn infants ≥34 weeks' gestation at birth. METHODS Resuscitations were video recorded. Tactile stimulations during PPV were noted and the timing, duration and surface area of applied stimulus were recorded. Respiratory flow waveforms were evaluated to determine the number of spontaneous breaths, VTe, leak and obstruction. Variables were recorded throughout each tactile stimulation episode and compared with those recorded in the same time period immediately before stimulation. RESULTS Twenty of 40 infants received tactile stimulation during PPV and we recorded 57 stimulations during PPV. During stimulation, the number of spontaneous breaths increased (median difference (IQR): 1 breath (0-3); padj<0.001) and VTe increased (0.5 mL/kg (-0.5 to 1.7), padj=0.028), whereas mask leak (0% (-20 to 1), padj=0.12) and percentage of obstructed inflations (0% (0-0), padj=0.14) did not change, compared with the period immediately prior to stimulation. Increased duration of stimulation (padj<0.001) and surface area of applied stimulus (padj=0.026) were associated with a larger increase in spontaneous breaths in response to tactile stimulation. CONCLUSIONS Tactile stimulation during PPV was associated with an increase in the number of spontaneous breaths compared with immediately before stimulation without a change in mask leak and obstruction. These data inform the discussion on continuing stimulation during PPV in term infants. TRIAL REGISTRATION NUMBER Australian and New Zealand Clinical Trial Registry (ACTRN12616000768493).

Abstract
BACKGROUND The feasibility and benefits of continuous sustained inflations (SIs) during chest compressions (CCs) during delayed cord clamping (physiological-based cord clamping; PBCC) are not known. We aimed to determine whether continuous SIs during CCs would reduce the time to return of spontaneous circulation (ROSC) and improve post-asphyxial blood pressures and flows in asystolic newborn lambs. METHODS Fetal sheep were surgically instrumented immediately prior to delivery at ~139 days' gestation and asphyxia induced until lambs reached asystole. Lambs were randomised to either immediate cord clamping (ICC) or PBCC. Lambs then received a single SI (SIsing; 30 s at 30 cmH2O) followed by intermittent positive pressure ventilation, or continuous SIs (SIcont: 30 s duration with 1 s break). We thus examined 4 groups: ICC +SIsing, ICC +SIcont, PBCC +SIsing, and PBCC +SIcont. Chest compressions and epinephrine administration followed international guidelines. PBCC lambs underwent cord clamping 10 min after ROSC. Physiological and oxygenation variables were measured throughout. RESULTS The time taken to achieve ROSC was not different between groups (mean (SD) 4.3±2.9 min). Mean and diastolic blood pressure was higher during chest compressions in PBCC lambs compared with ICC lambs, but no effect of SIs was observed. SIcont significantly reduced pulmonary blood flow, diastolic blood pressure and oxygenation after ROSC compared with SIsing. CONCLUSION We found no significant benefit of SIcont over SIsing during CPR on the time to ROSC or on post-ROSC haemodynamics, but did demonstrate the feasibility of continuous SIs during advanced CPR on an intact umbilical cord. Longer-term studies are recommended before this technique is used routinely in clinical practice.

Guidance for Cardiopulmonary Resuscitation of Children With Suspected or Confirmed COVID-19. Pediatrics 2022; 150:188494.

Abstract
This article aims to provide guidance to health care workers for the provision of basic and advanced life support to children and neonates with suspected or confirmed coronavirus disease 2019 (COVID-19). It aligns with the 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular care while providing strategies for reducing risk of transmission of severe acute respiratory syndrome coronavirus 2 to health care providers. Patients with suspected or confirmed COVID-19 and cardiac arrest should receive chest compressions and defibrillation, when indicated, as soon as possible. Because of the importance of ventilation during pediatric and neonatal resuscitation, oxygenation and ventilation should be prioritized. All CPR events should therefore be considered aerosol-generating procedures. Thus, personal protective equipment (PPE) appropriate for aerosol-generating procedures (including N95 respirators or an equivalent) should be donned before resuscitation, and high-efficiency particulate air filters should be used. Any personnel without appropriate PPE should be immediately excused by providers wearing appropriate PPE. Neonatal resuscitation guidance is unchanged from standard algorithms, except for specific attention to infection prevention and control. In summary, health care personnel should continue to reduce the risk of severe acute respiratory syndrome coronavirus 2 transmission through vaccination and use of appropriate PPE during pediatric resuscitations. Health care organizations should ensure the availability and appropriate use of PPE. Because delays or withheld CPR increases the risk to patients for poor clinical outcomes, children and neonates with suspected or confirmed COVID-19 should receive prompt, high-quality CPR in accordance with evidence-based guidelines.

Abstract
BACKGROUND In high-resource settings, postponing the interruption of cardiopulmonary resuscitation from 10 to 20 min after birth has been recently suggested, but data from low-resource settings are lacking. We investigated the outcome of newborns with Apgar scores of 0-1 at 10 min of resuscitative efforts in a low-resource setting. METHODS This observational substudy from the NeoSupra trial included all 49 late preterm/full-term newborns with Apgar scores of 0-1 at 10 min of resuscitation. The study was carried out at Mulago National Referral Hospital (Kampala, Uganda) between May 2018 and August 2019. Outcome measures were mortality and hypoxic-ischaemic encephalopathy in the first week of life. All resuscitations were video recorded and daily reviewed by trial researchers. RESULTS Median duration of resuscitation was 32 min (IQR 17-37). Advanced resuscitation was provided to 21/49 neonates (43%). Overall, 48 neonates (98%) died within 2 days of life (44 in the delivery room, three on the first day and one on the second day) and one survived at 1 week with severe hypoxic-ischaemic encephalopathy. CONCLUSION Our study adds information from a low-resource setting to the recent evidence from high-resource settings about prolonging the resuscitation in infants with Apgar scores of 0-1 at 10 min. The vast majority died in the delivery room despite prolonged resuscitative efforts. We confirm that duration of resuscitation should be tailored to the setting, while the focus in low-resource settings should be improving the quality of antenatal and immediately after birth care.

Abstract
Positive pressure ventilation via a facemask is a critical step in neonatal resuscitation but may be a difficult skill for frontline providers or trainees to master. A laryngeal mask is an alternative to endotracheal intubation for some newborns who require an advanced airway. We present the first case series in the United States in which a laryngeal mask was successfully utilized during resuscitation of newborns greater than or equal to 34 weeks’ gestation following an interdisciplinary quality improvement collaborative and focused training program.

Neonatal hemorrhage stroke and severe coagulopathy in a late preterm infant after receiving umbilical cord milking: A case report. World J Clin Cases 2022; 10:5365-5372. [PMID: 35812658 PMCID: PMC9210894 DOI: 10.12998/wjcc.v10.i16.5365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 12/23/2021] [Accepted: 04/04/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Umbilical cord milking (UCM) is an alternative placental transfusion method for delayed umbilical cord clamping in routine obstetric practice, allowing prompt resuscitation of an infant. Thus, UCM has been adopted at some tertiary neonatal centers for preterm infants to enhance placental-to-fetal transfusion. It is not suggested for babies less than 28 wk of gestational age because it is associated with severe brain hemorrhage. For late preterm or term infants who do not require resuscitation, cord management is recommended to increase iron levels and prevent the development of iron deficiency anemia, which is associated with impaired motor development, behavioral problems, and cognitive delays. Concerns remain about whether UCM increases the incidence of intraventricular hemorrhage. However, there are very few reports of late preterm infants presenting with neonatal hemorrhage stroke (NHS) and severe coagulopathy after receiving UCM. Here, we report a case of a late preterm infant born at 34 wk of gestation. She abruptly deteriorated, exhibiting signs and symptoms of NHS and severe coagulopathy after receiving UCM on the first day of life.
CASE SUMMARY A female preterm infant born at 34 wk of gestation received UCM after birth. She was small for her gestational age and described as vigorous with Apgar scores of 9 and 10 at one minute and five minutes of life, respectively. After hospitalization in the neonatal intensive care unit, she showed hypoglycemia and metabolic acidosis. The baby was administered glucose and sodium bicarbonate infusions. Intramuscular vitamin K1 was also used to prevent vitamin K deficiency. The baby developed umbilical cord bleeding and gastric bleeding on day 1 of life; a physical examination showed bilateral conjunctival hemorrhage, and a blood test showed thrombocytopenia, prolonged prothrombin time, prolonged activated partial thromboplastin time, low fibrinogen, raised D-dimer levels and anemia. A subsequent cranial ultrasound and computed tomography scan showed a left parenchymal brain hemorrhage with extension into the ventricular and subarachnoid spaces. The patient was diagnosed with NHS in addition to disseminated intravascular coagulation (DIC). Fresh frozen plasma (FFP) and prothrombin complex concentrate were given for coagulopathy. Red blood cell and platelet transfusions were provided for thrombocytopenia and anemia. A bolus of midazolam, intravenous calcium and phenobarbital sodium were administered to control seizures. The baby’s clinical condition improved on day 5 of life, and the baby was hospitalized for 46 d and recovered well without seizure recurrence. Our case report suggests that preterm infants who receive UCM should undergo careful clinical assessment for intracranial hemorrhage, NHS and severe coagulopathy that may develop under certain circumstances. Supportive management, such as intensive care, FFP and blood transfusion, is recommended when the development of massive NHS and associated DIC is suspected.
CONCLUSION Our case report suggests that for late preterm infants who are small for gestational age and who receive UCM for alternative placental transfusion, neonatal health care professionals should be cautious in assessing the development of NHS and severe coagulopathy. Neonatal health care professionals should also be more cautious in assessing the complications of late preterm infants after they receive UCM.

Making the Argument for Intact Cord Resuscitation: A Case Report and Discussion. CHILDREN 2022; 9:children9040517.

Abstract
We use a case of intact cord resuscitation to argue for the beneficial effects of an enhanced blood volume from placental transfusion for newborns needing resuscitation. We propose that intact cord resuscitation supports the process of physiologic neonatal transition, especially for many of those newborns appearing moribund. Transfer of the residual blood in the placenta provides the neonate with valuable access to otherwise lost blood volume while changing from placental respiration to breathing air. Our hypothesis is that the enhanced blood flow from placental transfusion initiates mechanical and chemical forces that directly, and indirectly through the vagus nerve, cause vasodilatation in the lung. Pulmonary vascular resistance is thereby reduced and facilitates the important increased entry of blood into the alveolar capillaries before breathing commences. In the presented case, enhanced perfusion to the brain by way of an intact cord likely led to regained consciousness, initiation of breathing, and return of tone and reflexes minutes after birth. Paramount to our hypothesis is the importance of keeping the umbilical cord circulation intact during the first several minutes of life to accommodate physiologic neonatal transition for all newborns and especially for those most compromised infants.

The management of late preterm infants: effects of rooming-in assistance versus direct admission to neonatal care units. Eur J Pediatr 2022; 181:1643-1649. [PMID: 34993626 DOI: 10.1007/s00431-021-04337-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 11/08/2021] [Accepted: 11/30/2021] [Indexed: 11/28/2022]
Abstract
Late preterm infants (LPIs) represent a significant percentage of all neonates (6-8%), but there are limited published data on their postnatal management. Our aim was to compare the frequency of neonatal intensive care unit (NICU) admission and the breastfeeding rate of LPIs born at 35+0-36+6 weeks of gestation who were cared for by initial rooming in strategy rather than directly admitted to the special care unit (SCU) and, eventually, to the NICU. We carried out a retrospective study in the perinatal centers of Careggi University Hospital (CUH) and San Giovanni di Dio Hospital in Florence, Italy, where the first and second strategies were applied, respectively. Main outcomes were LPIs admission rate at SCU/NICU and breastfeeding rate at discharge. We studied 190 LPIs born at SGDH and 240 born at CUH. The admission rate in SCU (81 vs. 43%; P < 0.001) and NICU (20 vs. 10%; P = 0.008) was higher in SGDH than in CUH, as was the exclusive breastfeeding rate (36 vs. 22%; P < 0.001). However, infants who were assisted in rooming-in at CUH and infants with similar clinical characteristics at SGDH had similar mixed (60 vs. 69%) and exclusive (35 vs. 31%) breastfeeding rates. Conclusion: Postnatal assistance of LPIs in rooming-in, eventually followed by admission in SCU/NICU based on their clinical conditions, allowed to safely halve their hospitalization. The assistance of infants in rooming-in did not negatively affect their breastfeeding rate. These results support the possibility of assisting LPIs in rooming-in. What is Known: • Late preterm infants represent a significant percentage of all neonates. • Early rooming-in and breastfeeding is recommended for late preterm infants. What is New: • Postnatal assistance of late preterm infants in rooming-in, followed when necessary by admission in neonatal units based on clinical conditions, allowed to safely avoid about half the number of hospitalizations in comparison with direct admission in neonatal units. • This strategy did not affect breastfeeding rate. Infants who were admitted to SCU/NICU after initial rooming-in had worst breastfeeding rate.

Association of delayed initiation of non-invasive respiratory support with pulmonary air leakage in outborn late-preterm and term neonates. Eur J Pediatr 2022; 181:1651-1660. [PMID: 35006375 DOI: 10.1007/s00431-021-04317-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 11/03/2021] [Accepted: 11/04/2021] [Indexed: 11/26/2022]
Abstract
UNLABELLED The frequency of non-invasive respiratory support use has increased in neonates of all gestational ages with respiratory distress (RD). However, the impact of delayed initiation of non-invasive respiratory support in outborn neonates remains poorly understood. This study aimed to identify the impact of the delayed initiation of non-invasive respiratory support in outborn, late-preterm, and term neonates. Medical records of 277 infants (gestational age of ≥ 35 weeks) who received non-invasive respiratory support as primary respiratory therapy < 24 h of age between 2016 and 2020 were retrospectively reviewed. Factors associated with respiratory adverse outcomes were investigated in 190 outborn neonates. Infants with RD were divided into two groups: mild (fraction of inspired oxygen [FiO2] ≤ 0.3) and moderate-to-severe RD (FiO2 > 0.3), depending on their initial oxygen requirements from non-invasive respiratory support. The median time for the initiation of non-invasive respiratory support at a tertiary center was 3.5 (2.2-5.0) h. Male sex, a high oxygen requirement (FiO2 > 0.3), high CO2 level, and respiratory distress syndrome were significant factors associated with adverse outcomes. Subgroup analysis revealed that in the moderate-to-severe RD group, delayed commencement of non-invasive respiratory support (≥ 3 h) was significantly associated with pulmonary air leakage (p = 0.033). CONCLUSION Our study shows that outborn neonates with moderate-to-severe RD, who were treated with delayed non-invasive respiratory support, were associated with an increased likelihood of pulmonary air leakage. Additional prospective studies are required to establish the optimal timing and methods of non-invasive respiratory support for outborn, late-preterm, and term infants. WHAT IS KNOWN • Non-invasive respiratory support is widely used in neonates of all gestational ages. • Little is known on the impact of delayed initiation of non-invasive respiratory support in outborn, late preterm, and term neonates. WHAT IS NEW • Male sex, high oxygen requirement (FiO2 >0.3), high initial CO2 level, and respiratory distress syndrome significantly correlated with adverse outcomes. • Outborn late-preterm and term neonates with high oxygen requirement who were treated with delayed non-invasive respiratory support indicated an increased likelihood of pulmonary air leakage.

Abstract
Although most newborns require no assistance to successfully transition to extrauterine life, the large number of births each year and limited ability to predict which newborns will need assistance means that skilled clinicians must be prepared to respond quickly and efficiently for every birth. A successful outcome is dependent on a rapid response from skilled staff who have mastered the cognitive, technical, and behavioral skills of neonatal resuscitation. Since its release in 1987, over 4.5 million clinicians have been trained by the American Heart Association and American Academy of Pediatrics Neonatal Resuscitation Program®. The guidelines used to develop this program were updated in 2020 and the Textbook of Neonatal Resuscitation, 8th edition, was released in June 2021. The updated guidelines have not changed the basic approach to neonatal resuscitation, which emphasizes the importance of anticipation, preparation, teamwork, and effective ventilation. Several practices have changed, including the prebirth questions, initial steps, use of electronic cardiac monitors, the initial dose of epinephrine, the flush volume after intravascular epinephrine, and the duration of resuscitation with an absent heart rate. In addition, the program has enhanced components of the textbook to improve learning, added new course delivery options, and offers 2 course levels to allow learners to study the material that is most relevant to their role during neonatal resuscitation. This review summarizes the recent changes to the resuscitation guidelines, the textbook, and the Neonatal Resuscitation Program course.

Abstract
The aim of our study was to evaluate the impact of the T-piece resuscitator in the delivery room management of pre-term neonates in a resource-limited setting. We compared the incidence rates of delivery room intubation, surfactant replacement therapy, pulmonary air leak syndrome, and pre-term very low birth weight infant mortality, before and after T-piece use. Bi-monthly neonatal resuscitation training sessions were conducted for healthcare providers during the study period. We emphasized hands-on experience with the T-piece resuscitator and delivery room early respiratory care practices during the post-intervention epoch. Our pre- and post-intervention data recorded statistically significant decline in delivery room intubations, a 32% decrease in surfactant replacement therapy, and a 57% decrease in air leaks in pre-term neonates. However, the use of T-piece resuscitator did not have a statistically significant effect on pre-term very low birth weight infant mortality.

Tactile stimulation in the delivery room: past, present, future. A systematic review. Pediatr Res 2022:10.1038/s41390-022-01945-9.

Abstract
In current resuscitation guidelines, tactile stimulation is recommended for infants with insufficient respiratory efforts after birth. No recommendations are made regarding duration, onset, and method of stimulation. Neither is mentioned how tactile stimulation should be applied in relation to the gestational age. The aim was to review the physiological mechanisms of respiratory drive after birth and to identify and structure the current evidence on tactile stimulation during neonatal resuscitation. A systematic review of available data was performed using PubMed, covering the literature up to April 2021. Two independent investigators screened the extracted references and assessed their methodological quality. Six studies were included. Tactile stimulation management, including the onset of stimulation, overall duration, and methods as well as the effect on vital parameters was analyzed and systematically presented. Tactile stimulation varies widely between, as well as within different centers and no consensus exists which stimulation method is most effective. Some evidence shows that repetitive stimulation within the first minutes of resuscitation improves oxygenation. Further studies are warranted to optimize strategies to support spontaneous breathing after birth, assessing the effect of stimulating various body parts respectively within different gestational age groups.

Abstract
We describe the process of implementation, adaptation, expansion and some related clinical intuitional impacts of the neonatal simulation program since its launch in 2016 in a non-simulation neonatal unit. The team has developed 6 types of curricula: 1 full-day course and 5 half-day workshops. A total of 35 free of charge simulation courses/workshops were conducted, 32 in Qatar and 3 abroad with a total of 799 diverse participants. There was a steady increase in the overall success rate of PICC insertion from 81.7% (309/378) to 97.6% (439/450) across 3 years (P < 0.0001). The first attempt PICC insertion success rate has been also increased from 57.7% (218/378) to 66.9% (301/450) across 3 years. The mean duration of PICC insertion has been improved from 39.7 ± 25 to 34.9 ± 12.4 min after implementing the program (P = 0.33). The mean duration of the LISA catheter insertion at the beginning of the workshop was 23.5 ± 15.9 compared to 12.1 ± 8.5 s at the end of the workshop (P = 0.001). When it came to clinical practise in real patients by the same participants, the overall LISA catheter insertion success rate was 100% and the first attempt success rate was 80.4%. The mean duration of LISA catheter insertion in real patients was 26.9 ± 13.9 s compared to the end of the workshop (P = 0.001). The mean duration of the endotracheal intubation at the beginning of the workshop was 12.5 ± 9.2 compared to 4.2 ± 3.8 s at the end of the workshop (P = 0.001). In real patients, the first-attempt intubation success rate has been improved from 37/139 (26.6%) in the first year to 141/187 (75.5%) in the second year after the program implementation (P = 0.001). The mean duration of successful endotracheal intubation attempts has been improved from 39.1 ± 52.4 to 20.1 ± 9.9 s (P = 0.78). As per the participants, the skills learned in the program sessions help in protecting neonates from potential harm and improve the overall neonatal outcome. Implementing a neonatal simulation program is a promising and feasible idea. Our experience can be generalised and replicated in other neonatal care institutions.

What does the evidence tell us? Revisiting optimal cord management at the time of birth. Eur J Pediatr 2022; 181:1797-1807.

Abstract
A newborn who receives a placental transfusion at birth from delayed cord clamping (DCC) obtains about 30% more blood volume than those with immediate cord clamping (ICC). Benefits for term neonates include higher hemoglobin levels, less iron deficiency in infancy, improved myelination out to 12 months, and better motor and social development at 4 years of age especially in boys. For preterm infants, benefits include less intraventricular hemorrhage, fewer gastrointestinal issues, lower transfusion requirements, and less mortality in the neonatal intensive care unit by 30%. Ventilation before clamping the umbilical cord can reduce large swings in cardiovascular function and help to stabilize the neonate. Hypovolemia, often associated with nuchal cord or shoulder dystocia, may lead to an inflammatory cascade and subsequent ischemic injury. A sudden unexpected neonatal asystole at birth may occur from severe hypovolemia. The restoration of blood volume is an important action to protect the hearts and brains of neonates. Currently, protocols for resuscitation call for ICC. However, receiving an adequate blood volume via placental transfusion may be protective for distressed neonates as it prevents hypovolemia and supports optimal perfusion to all organs. Bringing the resuscitation to the mother's bedside is a novel concept and supports an intact umbilical cord. When one cannot wait, cord milking several times can be done quickly within the resuscitation guidelines. Cord blood gases can be collected with optimal cord management. Conclusion: Adopting a policy for resuscitation with an intact cord in a hospital setting takes a coordinated effort and requires teamwork by obstetrics, pediatrics, midwifery, and nursing.

Abstract
AIM Despite the lack of evidence, current resuscitation guidelines recommend tactile stimulation in apneic infants within the first minutes of life. The aim was to investigate whether timing, duration or intensity of tactile stimulation influences the extent of non-invasive respiratory support in extremely preterm infants during neonatal resuscitation. METHODS In an observational study, we analyzed 47 video recordings and physiological parameters during postnatal transition in preterm infants below 320/7 weeks of gestational age. Infants were divided into three groups according to the intensity of respiratory support. RESULTS All infants were stimulated at least once during neonatal resuscitation regardless of their respiratory support. Only 51% got stimulated within the first minute. Rubbing the feet was the preferred stimulation method and was followed by rubbing or touching the chest. Almost all very preterm infants were exposed to stimulation and manipulation most of the time within their first 15 min of life. Tactile stimulation lasted significantly longer but stimulation at multiple body areas started later in infants receiving prolonged non-invasive respiratory support. CONCLUSION This observational study demonstrated that stimulation of very preterm infants is a commonly used and easy applicable method to stimulate spontaneous breathing during neonatal resuscitation. The concomitant physical stimulation of different body parts and therefore larger surface areas might be beneficial.

Abstract
OBJECTIVE To determine if e-learning interventions are efficient to review Neonatal Resuscitation Program (NRP) and to prevent performance deterioration in neonatal resuscitation of already-certified healthcare professionals. STUDY DESIGN In this scoping review, we searched for manuscripts published until June 2020 in five databases. We included all studies on e-learning use for NRP review in already-certified healthcare providers. RESULTS Among 593 abstracts retrieved, 38 full-text articles were assessed for eligibility. Five studies were included. Four studies evaluated the effectiveness of e-learning interventions immediately or months after their completion by providers. These interventions did not consistently enhance their NRP knowledge and their performance. One study showed that a growth mindset can influence positively neonatal resuscitation performance after an e-learning simulation. CONCLUSION There is not enough evidence to conclude that e-learning interventions can prevent neonatal resuscitation knowledge and performance decay in already-certified providers. More research is needed on the use of e-learning simulation-based scenarios to improve NRP retention.

Electrocardiogram for heart rate evaluation during preterm resuscitation at birth: a randomized trial. Pediatr Res 2022; 91:1445-1451. [PMID: 34645954 PMCID: PMC8513736 DOI: 10.1038/s41390-021-01731-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/18/2021] [Accepted: 08/24/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Although electrocardiogram (ECG) can detect heart rate (HR) faster compared to pulse oximetry, it remains unknown if routine use of ECG for delivery room (DR) resuscitation reduces the time to stabilization in preterm infants. METHODS Neonates <31 weeks' gestation were randomized to either an ECG-displayed or an ECG-blinded HR assessment in the DR. HR, oxygen saturation, resuscitation interventions, and clinical outcomes were compared. RESULTS During the study period, 51 neonates were enrolled. The mean gestational age in both groups was 28 ± 2 weeks. The time to stabilization, defined as the time from birth to achieve HR ≥100 b.p.m., as well as oxygen saturation within goal range, was not different between the ECG-displayed and the ECG-blinded groups [360 (269, 435) vs 345 (240, 475) s, p = 1.00]. There was also no difference in the time to HR ≥100 b.p.m. [100 (75, 228) vs 138 (88, 220) s, p = 0.40] or duration of positive pressure ventilation (PPV) [345 (120, 558) vs 196 (150, 273) s, p = 0.36]. Clinical outcomes were also similar between groups. CONCLUSIONS Although feasible and safe, the use of ECG in the DR during preterm resuscitation did not reduce time to stabilization. IMPACT Although feasible and apparently safe, routine use of the ECG in the DR did not decrease time to HR >100 b.p.m., time to stabilization, or use of resuscitation interventions such as PPV for preterm infants <31 weeks' gestational age. This article adds to the limited randomized controlled trial evidence regarding the impact of routine use of ECG during preterm resuscitation on DR clinical outcomes. Such evidence is important when considering recommendations for routine use of the ECG in the DR worldwide as such a recommendation comes with a significant cost burden.

Abstract
Resuscitation guidelines are developed and revised by medical societies throughout the world. These guidelines are increasingly based on evidence from preclinical and clinical research. The International Liaison Committee on Resuscitation reviews evidence for each resuscitation practice and provides summary consensus statements that inform resuscitation guideline committees. A similar process is used for different populations including neonatal, pediatric, and adult resuscitation. The NeoHeart 2020 Conference brought together experts in resuscitation to discuss recent evidence and guidelines for resuscitation practices. This review summarizes the main focus of discussion from this symposium.

The Use of a Disposable Umbilical Clamp to Secure an Umbilical Venous Catheter in Neonatal Emergencies—An Experimental Feasibility Study. CHILDREN 2021; 8:children8121093. [PMID: 34943289 PMCID: PMC8699894 DOI: 10.3390/children8121093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 11/21/2021] [Accepted: 11/24/2021] [Indexed: 11/16/2022]
Abstract
Recent guidelines recommend the umbilical venous catheter (UVC) as the optimal vascular access method during neonatal resuscitation. In emergencies the UVC securement may be challenging and time-consuming. This experimental study was designed to test the feasibility of new concepts for the UVC securement. Umbilical cord remnants were catheterized with peripheral catheters and secured with disposable umbilical clamps. Three different securement techniques were investigated. Secure 1: the disposable umbilical clamp was closed at the level of the inserted catheter. Secure 2: the clamp was closed at the junction of the catheter and plastic wings. Secure 3: the setting of Secure 2 was combined with an umbilical tape. The main outcomes were the feasibility of fluid administration and the maximum force to release the securement. This study shows that inserting peripheral catheters into the umbilical vein and securing them with disposable umbilical clamps is feasible. Rates of lumen obstruction and the effectiveness of the securement were superior with Secure 2 and 3 compared to Secure 1. This new approach may be a rewarding option for umbilical venous catheterization and securement particularly in low-resource settings and for staff with limited experience in neonatal emergencies. However, although promising, these results need to be confirmed in clinical trials before being introduced into clinical practice.

Lung Deposition of Surfactant Delivered via a Dedicated Laryngeal Mask Airway in Piglets. Pharmaceutics 2021; 13:pharmaceutics13111858. [PMID: 34834273 PMCID: PMC8621675 DOI: 10.3390/pharmaceutics13111858] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/20/2021] [Accepted: 10/25/2021] [Indexed: 11/17/2022] Open
Abstract
It is unknown if the lung deposition of surfactant administered via a catheter placed through a laryngeal mask airway (LMA) is equivalent to that obtained by bolus instillation through an endotracheal tube. We compare the lung deposition of surfactant delivered via two types of LMA with the standard technique of endotracheal instillation. 25 newborn piglets on continuous positive airway pressure support (CPAP) were randomized into three groups: 1—LMA-camera (integrated camera and catheter channel; catheter tip below vocal cords), 2—LMA-standard (no camera, no channel; catheter tip above the glottis), 3—InSurE (Intubation, Surfactant administration, Extubation; catheter tip below end of endotracheal tube). All animals received 100 mg·kg−1 of poractant alfa mixed with 99mTechnetium-nanocolloid. Surfactant deposition was measured by gamma scintigraphy as a percentage of the administered dose. The median (range) total lung surfactant deposition was 68% (10–85), 41% (5–88), and 88% (67–92) in LMA-camera, LMA-standard, and InSurE, respectively, which was higher (p < 0.05) in the latter. The deposition in the stomach and nasopharynx was higher with the LMA-standard. The surfactant deposition via an LMA was lower than that obtained with InSurE. Although not statistically significant, introducing the catheter below the vocal cords under visual control with an integrated camera improved surfactant LMA delivery by 65%.

Delivery Room Care for Premature Infants Born after Less than 25 Weeks' Gestation-A Narrative Review. CHILDREN-BASEL 2021; 8:children8100882. [PMID: 34682147 PMCID: PMC8534639 DOI: 10.3390/children8100882] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 09/28/2021] [Accepted: 09/29/2021] [Indexed: 11/16/2022]
Abstract
Premature infants born after less than 25 weeks' gestation are particularly vulnerable at birth and stabilization in the delivery room (DR) is challenging. After birth, infants born after <25 weeks' gestation develop respiratory and hemodynamic instability due to their immature physiology and anatomy. Successful stabilization at birth has the potential to reduce morbidities and mortalities, while suboptimal DR care could increase long-term sequelae. This article reviews current neonatal resuscitation guidelines and addresses challenges during DR stabilization in extremely premature infants born after <25 weeks' gestation at the threshold of viability.
