Withdrawal and withholding of life sustaining treatment (WWLST): an under recognised factor in the morbidity or mortality of periviable infants?-a narrative review

Background and Objective

The morbidity and mortality of infants born extremely preterm varies substantially across networks, within countries and throughout the globe. Most of the literature tends to focus on the management at birth and choices around active resuscitation of extremely preterm infants. Withdrawal and withholding of life sustaining treatment (WWLST) is an important and central process in the neonatal intensive care unit (NICU) and practices vary substantially. As such, our objective in this review was to explore whether end of life decisions also contribute to variations in the morbidity and mortality of periviable infants.

Methods

This narrative literature review is based on studies from the last 15 years found using several searches of medical databases (OVID Medline, Scopus and Cochrane Systematic Reviews) performed between March 2021 and December 2023.

Key Content and Findings

Just as outcomes in periviable infants vary, the rates of and processes behind WWLST differ in the periviable population. Variation increases as gestational age decreases. Parental involvement is crucial to share decision making but the circumstances and rates of parental involvement differ. Strict guidelines in end-of-life care may not be appropriate, however there is a need for more targeted guidance for periviable infants as a specific population. The current literature available relating to periviable infants or WWLST is minimal, with many datasets rapidly becoming outdated.

Conclusions

Further research is needed to establish the role of WWLST in variation of periviable infants' outcomes. The unification of data, acquisition of more recent datasets and inclusion of variables relating to end-of-life decisions in data collection will aid in this process.

European Training Requirements in Neonatology 2021: The ESPR, EAP, and UEMS Accredited European Syllabus for Neonatal Training

INTRODUCTION

The European Union stipulates transnational recognition of professional qualifications for several sectoral professions, including medical doctors. The Union of European Medical Specialists (UEMS), in its "Charter on Training of Medical Specialists," defines the principles for high-level medical training. These principles are manifested in the framework for European Training Requirements (ETR), ensuring medical training reflects modern medical practice and current scientific findings. In 1998, the European Society for Paediatric Research developed the first ETR for Neonatology. We present the ETR Neonatology in its third iteration (ETR III), ratified by the European Academy of Paediatrics (EAP), and approved by UEMS in 2021.

METHODS

In generating the ETR III, existing European policy documents on training requirements, including national syllabi and the European Standards of Care for Newborn Health were considered. To ensure the ETR III meets a pan-European standard of expertise in Neonatology, input from representatives from 27 European national paediatric/neonatal societies, and a European parent organisation, was sought.

RESULTS

The ETR III summarises the requirements of contemporary training programs in Neonatology and offers a system for accrediting trainers and training centres. We describe the content of the ETR III training syllabus and means of gaining and assessing competency as a medical care provider in Neonatology.

CONCLUSION

Graduates of courses following the ETR III Neonatology will obtain a certificate of satisfactory training completion which should be accepted by all European member states as a baseline qualification to practice as a specialist in neonatal medicine, enabling mutual recognition of status throughout Europe.

Clinical decision thresholds for surfactant administration in preterm infants: a systematic review and network meta-analysis

Background

The ideal threshold at which surfactant administration in preterm neonates with respiratory distress syndrome (RDS) is most beneficial is contentious. The aim of this systematic review was to determine the optimal clinical criteria to guide surfactant administration in preterm neonates with RDS.

Methods

The systematic review was registered in PROSPERO (CRD42022309433). Medline, Embase, CENTRAL and CINAHL were searched from inception till 16th May 2023. Only randomized controlled trials (RCTs) were included. A Bayesian random effects network meta-analysis (NMA) evaluating 33 interventions was performed. The primary outcome was requirement of invasive mechanical ventilation (IMV) within 7 days of life.

Findings

58 RCTs were included. In preterm neonates ≤30 weeks after adjusting for the confounding factor of modality of surfactant administration, an arterial alveolar oxygen tension ratio (aAO2) <0.36 (FiO2: 37-55%) was ranked the best threshold for decreasing the risk of IMV, very low certainty. Further, surfactant administration at an FiO2 40-45% possibly decreased mortality compared to rescue treatment when respiratory failure was diagnosed, certainty very low. The reasonable inference that could be drawn from these findings is that surfactant administration may be considered in preterm neonates of ≤30 weeks' with RDS requiring an FiO2 ≥ 40%. There was insufficient evidence for the comparison of FiO2 thresholds: 30% vs. 40%. The evidence was sparse for surfactant administration guided by lung ultrasound. For the sub-group >30 weeks, nebulized surfactant administration at an FiO2 < 30% possibly increased the risk of IMV compared to Intubate-Surfactant-Extubate at FiO2 < 30% and 40%, and less invasive surfactant administration at FiO2 40%, certainty very low.

Interpretation

Surfactant administration may be considered in preterm neonates of ≤30 weeks' with RDS if the FiO2 requirement is ≥40%. Future trials are required comparing lower FiO2 thresholds of 30% vs. 40% and that guided by lung ultrasound.

Funding

Sedation for less invasive surfactant administration in preterm infants: a systematic review and meta-analysis

BACKGROUND

Sedation to preterm neonates receiving less invasive surfactant administration (LISA) for respiratory distress syndrome is controversial.

METHODS

Systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies (OS) to evaluate the effect of sedative drugs for LISA on respiratory outcomes and adverse effects.

RESULTS

One RCT (78 neonates) and two OS (519 neonates) were analyzed in pairwise meta-analysis and 30 studies (2164 neonates) in proportion-based meta-analysis. Sedative drugs might not affect the duration of the procedure [RCT: mean difference (MD) (95% CI); -11 (-90; 67) s; OS: MD 95% CI: -60 (-178; 58) s; low certainty of evidence (CoE)]. Evidence for success at the first attempt and rescue intubation was uncertain (very low CoE). The risk of nasal intermittent positive pressure ventilation [RCT: 1.97 (1.38-2.81); OS: RR, 95% CI: 2.96 (1.46; 6.00), low CoE], desaturation [RCT: RR, 95% CI: 1.30 (1.03; 1.65), low CoE], and apnea [OS: RR, 95% CI: 3.13 (1.35; 7.24), very low CoE] might be increased with sedation. Bradycardia, hypotension, and mechanical ventilation were comparable between groups (low CoE).

CONCLUSIONS

Use of sedative drugs for LISA temporarily affects the newborn's breathing. Further trials are warranted to explore the use of sedation for LISA.

IMPACT

The effect of sedative drugs (analgesics, sedatives, anesthetics) compared to the effect of no-sedation for LISA in preterm infants with RDS is underexplored. This systematic review and meta-analysis assesses the impact of sedative drugs compared to no-sedation for LISA on short-term pulmonary outcomes and potential adverse events. Sedative drugs for LISA temporarily affect the newborn's breathing (desaturation, apnea) and increase the need for nasal intermittent positive pressure ventilation. For most outcomes, certainty of evidence is low/very low.

Survey of transfusion practices in preterm infants in Europe

BACKGROUND

Preterm infants commonly receive red blood cell (RBC), platelet and fresh frozen plasma (FFP) transfusions. The aim of this Neonatal Transfusion Network survey was to describe current transfusion practices in Europe and to compare our findings to three recent randomised controlled trials to understand how clinical practice relates to the trial data.

METHODS

From October to December 2020, we performed an online survey among 597 neonatal intensive care units (NICUs) caring for infants with a gestational age (GA) of <32 weeks in 18 European countries.

RESULTS

Responses from 343 NICUs (response rate: 57%) are presented and showed substantial variation in clinical practice. For RBC transfusions, 70% of NICUs transfused at thresholds above the restrictive thresholds tested in the recent trials and 22% below the restrictive thresholds. For platelet transfusions, 57% of NICUs transfused at platelet count thresholds above 25×10⁹/L in non-bleeding infants of GA of <28 weeks, while the 25×10⁹/L threshold was associated with a lower risk of harm in a recent trial. FFP transfusions were administered for coagulopathy without active bleeding in 39% and for hypotension in 25% of NICUs. Transfusion volume, duration and rate varied by factors up to several folds between NICUs.

CONCLUSIONS

Transfusion thresholds and aspects of administration vary widely across European NICUs. In general, transfusion thresholds used tend to be more liberal compared with data from recent trials supporting the use of more restrictive thresholds. Further research is needed to identify the barriers and enablers to incorporation of recent trial findings into neonatal transfusion practice.

Assessment of Change in Practice of Routine Tracheal Suctioning Approach of Non-Vigorous Infants Born through Meconium-Stained Amniotic Fluid: A Pragmatic Systematic Review and Meta-Analysis of Evidence outside Randomized Trials

AIM

The 2015 recommendation of the International Liaison Committee on Resuscitation of no routine tracheal suctioning in non-vigorous neonates born through meconium-stained amniotic fluid (MSAF) was based on very low certainty of evidence (CoE) necessitating ongoing monitoring. The aim of this systematic review was to perform a meta-analysis of observational studies comparing the effect of implementing immediate resuscitation without routine tracheal suctioning versus with routine suctioning in neonates born through MSAF.

METHODS

MEDLINE, Embase, CENTRAL, and Web of Science were searched. Observational studies with a before-and-after design were included. Two authors extracted data independently. CoE based on GRADE recommendations was performed.

RESULTS

13 studies were included. Clinical benefit or harm could not be excluded for the composite primary outcome of mortality or requirement of extracorporeal membranous oxygenation (ECMO) (relative risk, 95% confidence interval: 0.74 [0.47-1.17]), and mortality (0.68 [0.42-1.11]). "Routine tracheal suctioning" epoch had possibly lesser risk of meconium aspiration syndrome (MAS) when compared to "no routine tracheal suctioning" epoch (0.68 [0.47-0.99]). "Routine tracheal suctioning" epoch also possibly had a lower risk of hospital admission for respiratory symptoms, requirement of non-invasive respiratory support, invasive mechanical ventilation, surfactant treatment, air leak, and low-flow oxygen therapy. Clinical benefit or harm could not be excluded for the outcome of mortality or ECMO among those diagnosed with MAS (1.09 [0.86-1.39]), but "routine tracheal suctioning" was possibly associated with lower risk of respiratory morbidities among those diagnosed with MAS. The CoE was very low for most of the outcomes evaluated.

CONCLUSIONS

Due to the very low CoE for the outcomes evaluated, no definitive conclusions can be drawn warranting the need for additional studies.

Non-invasive ventilatory support in neonates: An evidence-based update

Non-invasive ventilatory support (NIV) is considered the gold standard in the care of preterm infants with respiratory distress syndrome (RDS). NIV from birth is superior to mechanical ventilation (MV) for the prevention of death or bronchopulmonary dysplasia (BPD), with a number needed to treat between 25 and 35. Various methods of NIV are available, some of them extensively researched and with well proven efficacy, whilst others are needing further research. Nasal continuous positive airway pressure (nCPAP) has replaced routine invasive mechanical ventilation (MV) for the initial stabilization and the treatment of RDS. Choosing the most suitable form of NIV and the most appropriate patient interface depends on several factors, including gestational age, underlying lung pathophysiology and the local facilities. In this review, we present the currently available evidence on NIV as primary ventilatory support to preventing intubation and for secondary ventilatory support, following extubation. We review nCPAP, nasal high-flow cannula, nasal intermittent positive airway pressure ventilation, bi-level positive airway pressure, nasal high-frequency oscillatory ventilation and nasal neurally adjusted ventilatory assist modes. We also discuss most suitable NIV devices and patient interfaces during resuscitation of the newborn in the delivery room.

Surfactant therapy in late preterm and term neonates with respiratory distress syndrome: a systematic review and meta-analysis

BACKGROUND

There are no evidence-based recommendations for surfactant use in late preterm (LPT) and term infants with respiratory distress syndrome (RDS).

OBJECTIVE

To investigate the safety and efficacy of surfactant in LPT and term infants with RDS.

METHODS

Systematic review, meta-analysis and evidence grading.

INTERVENTIONS

Surfactant therapy versus standard of care.

MAIN OUTCOME MEASURES

Mortality and requirement for invasive mechanical ventilation (IMV).

RESULTS

Of the 7970 titles and abstracts screened, 17 studies (16 observational studies and 1 randomised controlled trial (RCT)) were included. Of the LPT and term neonates with RDS, 46% (95% CI 40% to 51%) were treated with surfactant. We found moderate certainty of evidence (CoE) from observational studies evaluating infants supported with non-invasive respiratory support (NRS) or IMV that surfactant use may be associated with a decreased risk of mortality (OR 0.45, 95% CI 0.32 to 0.64). Very low CoE from observational trials in which surfactant was administered at FiO₂ >0.30-0.40 to infants on Continuous Positive Airway Pressure (CPAP) indicated that surfactant did not decrease the risk of IMV (OR 1.20, 95% CI 0.40 to 3.56). Very low to low CoE from the RCT and observational trials showed that surfactant use was associated with a significant decrease in risk of air leak, persistent pulmonary hypertension of the newborn (PPHN), duration of IMV, NRS and hospital stay.

CONCLUSIONS

Current evidence base on surfactant therapy in LPT and term infants with RDS indicates a potentially decreased risk of mortality, air leak, PPHN and duration of respiratory support. In view of the low to very low CoE and widely varying thresholds for deciding on surfactant replacement in the included studies, further trials are needed.

Comparison of intraosseous and intravenous epinephrine administration during resuscitation of asphyxiated newborn lambs

OBJECTIVE

Intraosseous access is recommended as a reasonable alternative for vascular access during newborn resuscitation if umbilical access is unavailable, but there are minimal reported data in newborns. We compared intraosseous with intravenous epinephrine administration during resuscitation of severely asphyxiated lambs at birth.

METHODS

Near-term lambs (139 days' gestation) were instrumented antenatally for measurement of carotid and pulmonary blood flow and systemic blood pressure. Intrapartum asphyxia was induced by umbilical cord clamping until asystole. Resuscitation commenced with positive pressure ventilation followed by chest compressions and the lambs received either intraosseous or central intravenous epinephrine (10 μg/kg); epinephrine administration was repeated every 3 min until return of spontaneous circulation (ROSC). The lambs were maintained for 30 min after ROSC. Plasma epinephrine levels were measured before cord clamping, at end asphyxia, and at 3 and 15 min post-ROSC.

RESULTS

ROSC was successful in 7 of 9 intraosseous epinephrine lambs and in 10 of 12 intravenous epinephrine lambs. The time and number of epinephrine doses required to achieve ROSC were similar between the groups, as were the achieved plasma epinephrine levels. Lambs in both groups displayed a similar marked overshoot in systemic blood pressure and carotid blood flow after ROSC. Blood gas parameters improved more quickly in the intraosseous lambs in the first 3 min, but were otherwise similar over the 30 min after ROSC.

CONCLUSIONS

Intraosseous epinephrine administration results in similar outcomes to intravenous epinephrine during resuscitation of asphyxiated newborn lambs. These findings support the inclusion of intraosseous access as a route for epinephrine administration in current guidelines.

Safe emergency neonatal airway management: current challenges and potential approaches

This review examines the airway adjuncts currently used to acutely manage the neonatal airway. It describes the challenges encountered with facemask ventilation and intubation. Evidence is presented on how to optimise intubation safety and success rates with the use of videolaryngoscopy and attention to the intubation environment. The supraglottic airway (laryngeal mask airway) is emerging as a promising neonatal airway adjunct. It can be used effectively with little training to provide a viable alternative to facemask ventilation and intubation in neonatal resuscitation and be used as an alternative conduit for the administration of surfactant.

Respiratory management and bronchopulmonary dysplasia in extremely preterm infants: a comparison of practice between centres in Oxford and Melbourne

OBJECTIVE

Considerable variation in the care of extremely low gestational age infants (ELGAN) contributes to the variation in incidence of bronchopulmonary dysplasia (BPD). We compared management and outcomes of two neonatal centres with different respiratory support strategies.

STUDY DESIGN

Retrospective cohort study of infants <28 weeks gestational age treated at two units in Australia and the UK between 2015 and 2017.

RESULT

Of 492 infants, the overall incidence of BPD for extremely preterm infants was 62.20% and was similar across both sites (64.84% at Monash vs. 60.65% at Oxford). Independent predictors for the development of BPD or mortality included the days on mechanical ventilation (MV, adjusted OR 1.13, 95% Cl 1.07-1.19) and use of inhaled nitric oxide (adjusted OR 13.42, 95% Cl 1.75-103.28).

CONCLUSION

Primary choice of non-invasive respiratory support had no significant impact on BPD development. Duration of MV and using nitric oxide were independent predictors for death or BPD.

Delivery room CPAP in improving outcomes of preterm neonates in low-and middle-income countries: A systematic review and network meta-analysis

AIM

To study the impact of delivery room continuous positive airway pressure (DRCPAP) on outcomes of preterm neonates in low- and middle- income countries (LMICs) by comparing with interventions: oxygen supplementation, late DRCPAP, DRCPAP with sustained inflation, DRCPAP with surfactant and invasive mechanical ventilation (IMV).

METHODS

Medline, Embase, CENTRAL, WOS and CINAHL searched. Observational studies and randomized controlled trials (RCTs) were included. Pair-wise meta-analysis and Bayesian network meta-analysis (NMA) were utilized. Primary outcome was receipt of IMV.

RESULTS

Data from 11 of the 18 included studies (4 observational studies, 7 RCTs) enrolling 4210 preterm infants was synthesized. Moderate certainty of evidence (CoE) from NMA of RCTs comparing DRCPAP with surfactant administration versus DRCPAP alone suggested no decrease in subsequent receipt of IMV [Risk ratio (RR); 95% Credible Interval (CrI): 0.73; (0.34, 1.40)]. Very low CoE from observational studies comparing use of DRCPAP versus oxygen supplementation indicated a trend towards decreased IMV [RR; 95% Confidence Interval (CI): 0.75; (0.56-1.00)]. Although moderate CoE from NMA evaluating DRCPAP versus oxygen supplementation showed a trend towards decreased receipt of surfactant, it did not reach statistical significance [RR; 95% CrI: 0.69; (0.44, 1.06)]. Moderate CoE from NMA indicated that none of the interventions, when compared with use of supplemental oxygen alone or with each other decreased mortality or bronchopulmonary dysplasia.

LIMITATIONS

CoE was very low for primary outcome.

CONCLUSIONS

Present evidence is not sufficient for use of DRCPAP, but also did not show harm. Since it seems unlikely that there are marked variations in patient physiology to explain the difference in efficacy between high income countries and LMICs, we suggest future research evaluating other barriers in improving the effectiveness of DRCPAP in LMICs.

ELBW and ELGAN outcomes in developing nations-Systematic review and meta-analysis

Context

Morbidity and mortality amongst extremely low birth weight (ELBW) and extremely low gestational age neonates (ELGANs) in developing nations has not been well studied.

Objectives

Evaluate survival until discharge, short- and long-term morbidities of ELBW and ELGANs in LMICs.

Data sources

CENTRAL, EMBASE, MEDLINE and Web of Science.

Study selection

Prospective and retrospective observational studies were included.

Data extraction and synthesis

Four authors extracted data independently. Random-effects meta-analysis of proportions was used to synthesize data, modified QUIPS scale to evaluate quality of studies and GRADE approach to ascertain the certainty of evidence (CoE).

Results

192 studies enrolling 22,278 ELBW and 18,338 ELGANs were included. Survival was 34% (95% CI: 31% - 37%) (CoE–low) for ELBW and 39% (34% - 44%) (CoE—moderate) for ELGANs. For ELBW neonates, the survival for low-income (LI), lower middle-income (LMI) and upper middle income (UMI) countries was 18% (11% - 28%), 28% (21% - 35%) and 39% (36% - 42%), respectively. For ELGANs, it was 13% (8% - 20%) for LI, 28% (21% - 36%) for LMI and 48% (42% - 53%) for UMI countries. There was no difference in survival between two epochs: 2000–2009 and 2010–2020. Except for necrotising enterocolitis [ELBW and ELGANs—8% (7% - 10%)] and periventricular leukomalacia [ELBW—7% (4% - 11%); ELGANs—6% (5%-7%)], rates of all other morbidities were higher compared to developed nations. Rates of neurodevelopmental impairment was 17% (7% - 34%) in ELBW neonates and 29% (23% - 37%) in ELGANs.

Limitations

CoE was very low to low for all secondary outcomes.

Conclusions

Mortality and morbidity amongst ELBW and ELGANs is still a significant burden in LMICs. CoE was very low to low for all the secondary outcomes, emphasizing the need for high quality prospective cohort studies.

Enteral Feeding Strategies in Preterm Neonates ≤32 weeks Gestational Age: A Systematic Review and Network Meta-Analysis

INTRODUCTION

Critical aspects of time of feed initiation, advancement, and volume of feed increment in preterm neonates remain largely unanswered.

METHODS

Medline , Embase, CENTRAL and CINAHL were searched from inception until 25th September 2020. Network meta-analysis with the Bayesian approach was used. Randomized controlled trials (RCTs) evaluating preterm neonates ≤32 weeks were included. Feeding regimens were divided based on the following categories: initiation day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); advancement day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); increment volume: small volume (SV) (<20 mL/kg/day), moderate volume (MoV) (20-< 30 mL/kg/day), and large volume (≥30 mL/kg/day); and full enteral feeding from the first day. Sixteen regimens were evaluated. Combined outcome of necrotizing enterocolitis (NEC) stage ≥ II or mortality before discharge was the primary outcome.

RESULTS

A total of 39 studies enrolled around 6,982 neonates. Early initiation (EI) with moderately early or late advancement using MoV increment enteral feeding regimens appeared to be most efficacious in decreasing the risk of NEC or mortality when compared to EI and early advancement with SV increment (risk ratio [95% credible interval]: 0.39 [0.12, 0.95]; 0.34 [0.10, 0.86]) (GRADE-very low).

CONCLUSIONS

Early initiated, moderately early, or late advanced with MoV increment feeding regimens might be most appropriate in decreasing the risk of NEC stage ≥II or mortality. In view of the certainty of evidence being very low, adequately powered RCTs evaluating these 2 strategies are warranted.

Devices for Administering Ventilation at Birth: A Systematic Review

CONTEXT

Positive pressure ventilation (PPV) is the most important intervention during neonatal resuscitation.

OBJECTIVE

To compare T-piece resuscitators (TPRs), self-inflating bags (SIBs), and flow-inflating bags for newborns receiving PPV during delivery room resuscitation.

DATA SOURCES

Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Database of Systematic Reviews, and trial registries (inception to December 2020).

STUDY SELECTION

Randomized, quasi-randomized, interrupted time series, controlled before-and-after, and cohort studies were included without language restrictions.

DATA EXTRACTION

Two researchers independently extracted data, assessed the risk of bias, and evaluated the certainty of evidence. The primary outcome was in-hospital mortality. When appropriate, data were pooled by using fixed-effect models.

RESULTS

Meta-analysis of 4 randomized controlled trials (1247 patients) revealed no significant difference between TPR and SIB for in-hospital mortality (risk ratio 0.74; 95% confidence interval [CI] 0.40 to 1.34). Resuscitation with a TPR resulted in a shorter duration of PPV (mean difference -19.8 seconds; 95% CI -27.7 to -12.0 seconds) and lower risk of bronchopulmonary dysplasia (risk ratio 0.64; 95% CI 0.43 to 0.95; number needed to treat 32). No differences in clinically relevant outcomes were found in 2 randomized controlled trials used to compare SIBs with and without positive end-expiratory pressure valves. No studies used to evaluate flow-inflating bags were found.

LIMITATIONS

Certainty of evidence was very low or low for most outcomes.

CONCLUSIONS

Resuscitation with a TPR compared with an SIB reduces the duration of PPV and risk of bronchopulmonary dysplasia. A strong recommendation cannot be made because of the low certainty of evidence. There is insufficient evidence to determine the effectiveness of positive end-expiratory pressure valves when used with SIBs.

Care practices and outcomes of extremely preterm neonates born at 22-24 weeks -A single centre experience

BACKGROUND

Wide variation in the care practices and survival rates of neonates born at peri-viable gestational ages of 22 +0 -24 +6 weeks exists. This study elucidates the postnatal risk factors for morbidity/mortality, contrasts the care practices and short-term outcomes of this vulnerable group of preterm neonates from a single center with others.

METHODS

Retrospective study of neonates born at 22 +0 -24 +6 weeks in a level 3 neonatal intensive care unit in UK, over a period of 4 years (2016-2019).

RESULTS

94 neonates given active care studied. Survival until discharge was 51.1%(22-23 wks -44%, 24 wks -59.1%) and survival with no major brain injury (MBI) [grade III/IV IVH, cystic periventricular leukomalacia] was 38.3%(22-23 wks -32%, 24 wks -45.4%). Of those who survived until discharge, 75%had no MBI (22-23 wks -72.7%, 24 wks -76.9%). Neonates requiring significant respiratory support within first 72 hours as well as needing rescue high frequency ventilation had significantly high risk of mortality or MBI [aOR -7.17 (2.24-25.79), p = 0.00; 4.76 (1.43-20.00), p = 0.01].

CONCLUSIONS

Survival rate differed from other centres. MBI was low amongst survivors. Severe respiratory disease in the initial days was associated with a higher risk of death or MBI.

Resuscitation of non-vigorous neonates born through meconium-stained amniotic fluid: post policy change impact analysis

BACKGROUND

We investigated the impact of policy change in delivery room resuscitation from routine endotracheal (ET) suctioning of non-vigorous neonates born through meconium-stained amniotic fluid (MSAF) to immediate non-invasive respiratory support.

DESIGN

Single-centre cohort study. Prospective group (October 2016-September 2017)-non-vigorous neonates born through MSAF managed according to the current (2015) guidance of commencing respiratory support without prior suctioning. Retrospective group (August 2015-July 2016)-non-vigorous neonates born through MSAF who underwent routine ET suctioning.

RESULTS

1138 neonates born through MSAF were analysed. No differences in the incidence of meconium aspiration syndrome (MAS), requirement of mechanical ventilation, inhaled nitric oxide or surfactant therapy were found between groups. Less neonatal intensive care unit (NICU) admissions were necessary in the prospective cohort compared with the retrospective group (19.1% vs 55.6%, respectively; p<0.05).

CONCLUSION

The policy change towards not routinely suctioning non-vigorous neonates born through MSAF at birth was not associated with an increase in the local incidence of MAS and was associated with fewer NICU admissions.

T-piece resuscitator or self-inflating bag during neonatal resuscitation: a scoping review

BACKGROUND

To identify the evidence for administering positive pressure ventilation (PPV) to infants at birth by either T-piece resuscitator (TPR) or self-inflating bag (SIB), and to determine whether a full systematic review (SR) is warranted.

METHODS

Guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews, eligible studies included peer-reviewed human studies, prospectively or retrospectively comparing a TPR vs. SIB for administering PPV at birth. Databases searched were OVID Medline, PubMed, Embase and the Cochrane Central Register of Controlled Trials. Review Manager software was used for the data analysis.

RESULTS

Following electronic literature search and review, data from four eligible studies (3 RCT and 1 observational study), enrolling a total of 2889 patients, were included. Studies differed regarding the investigated populations, reported outcomes and came from different geographical areas. In particular for preterm infants, use of TPR for providing PPV may improve survival, result in fewer intubations at birth and decrease the incidence of bronchopulmonary dysplasia.

CONCLUSIONS

This scoping review identified two new studies with substantive new evidence, pointing towards improved survival, decreased bronchopulmonary dysplasia and fewer intubations at birth, in particular among preterm infants treated with TPR. Full SR of the literature is advised.

IMPACT

This scoping review identified studies comparing TPR vs. SIB for respiratory support of newborn infants previously not included in the International Liaison Committee on Resuscitation (ILCOR) recommendations. Our review found substantive new evidence highlighting that device choice may impact the outcomes of compromised newborn infants'. This scoping review stipulates the need for full SR and updated meta-analysis of studies investigating supportive equipment for stabilizing infants at birth in order to inform ILCOR treatment recommendations.

Less-Invasive Surfactant Administration for Neonatal Respiratory Distress Syndrome: A Consensus Guideline

INTRODUCTION

Less-invasive surfactant administration (LISA) is a method of surfactant delivery to preterm infants for treating respiratory distress syndrome (RDS), which can reduce the composite risk of death or bronchopulmonary dysplasia and the time on mechanical ventilation.

METHODS

A systematic literature search of studies published up to April 2021 on minimally invasive catheter surfactant delivery in preterm infants with RDS was conducted. Based on these studies, with parental feedback sought via an online questionnaire, 9 UK-based specialists in neonatal respiratory disease developed their consensus for implementing LISA. Recommendations were developed following a modified, iterative Delphi process using a questionnaire employing a 9-point Likert scale and an a priori level of agreement/disagreement.

RESULTS

Successful implementation of LISA can be achieved by training the multidisciplinary team and following locally agreed guidance. From the time of the decision to administer surfactant, LISA should take <30 min. The comfort of the baby and requirements to maintain non-invasive respiratory support are important. While many infants can be managed without requiring additional sedation/analgesia, fentanyl along with atropine may be considered. Parents should be provided with sufficient information about medication side effects and involved in treatment discussions.

CONCLUSION

LISA has the potential to improve outcomes for preterm infants with RDS and can be introduced as a safe and effective part of UK-based neonatal care with appropriate training.

To Sedate or Not to Sedate for Less Invasive Surfactant Administration: An Ethical Approach

Less invasive surfactant administration (LISA) is an effective, minimally invasive technique of administering surfactant to infants with respiratory distress syndrome. While termed less invasive, LISA still requires airway instrumentation with direct laryngoscopy, thus may be considered painful. However, the issue of whether or not to routinely sedate infants for LISA remains contentious, with significant variation in practice between centres. Proponents for giving pharmacological analgesia and/or sedation predominantly focus on patient comfort during the procedure. However, those who favour non-pharmacological measures of pain management focus on the potential for procedural success without the risk of adverse events, such as respiratory depression and potentially the need for escalation to intubation, which may occur with pharmacological agents. The neonatal population who may benefit from LISA is varied. Due to this variety in presentation type, gestational age, and unit experience, there is a need to provide an individualized, tailored approach to sedation and analgesia for these infants. Using a blanket approach to sedation will lead to infants being exposed to sedative medications on the assumption of potential distress, rather than in response to signs of actual distress. This places the infant at risk of the adverse reactions, potentially without them ever having needed the beneficial effect of the medications. This seems an unnecessary risk. This article explores the ethical arguments pertaining to analgesia and sedation during the LISA technique, concluding that a standardized approach to the usage of pharmacological sedation is undesirable. Moreover, we maintain that procedural analgesia and sedation should be based on individualized, infant-centred assessment, rather than on a rigid, standardized approach.

Efficacy of noninvasive respiratory support modes for primary respiratory support in preterm neonates with respiratory distress syndrome: Systematic review and network meta-analysis

OBJECTIVES

To compare the efficacy of different noninvasive respiratory support (NRS) modes for primary respiratory support of preterm infants with respiratory distress syndrome (RDS).

DESIGN

Systematic review and network meta-analysis using the Bayesian random-effects approach. MEDLINE, EMBASE, and CENTRAL were searched.

INTERVENTIONS

High flow nasal cannula (HFNC), continuous positive airway pressure (CPAP), bilevel CPAP (BiPAP), noninvasive positive pressure ventilation (NIPPV).

MAIN OUTCOME MEASURES

Requirement of invasive mechanical ventilation (MV), any treatment failure.

RESULTS

A total of 35 studies including 4078 neonates were included. NIPPV was more effective in decreasing the requirement of MV than CPAP (risk ratios [95% credible interval]: 0.60 [0.44, 0.77]) and HFNC [0.66 (0.43, 0.97)]. Surface under the cumulative ranking curve (SUCRA) for NIPPV, BiPAP, HFNC, and CPAP were 0.95, 0.59, 0.32, and 0.13. For the outcome of treatment failure, both NIPPV and BiPAP were more efficacious compared to CPAP and HFNC (0.56 [0.44, 0.71] {NIPPV vs CPAP}, 0.69 [0.51, 0.93] {BiPAP vs CPAP}, 0.42 [0.30, 0.63] {NIPPV vs HFNC}, 0.53 [0.35, 0.81] {BiPAP vs HFNC}). The SUCRA for NIPPV, BiPAP, CPAP, and HFNC were 0.96, 0.70, 0.32, and 0.01. NIPPV was associated with a reduced risk of air leak compared to BiPAP and CPAP (0.36 [0.16, 0.73]; 0.54 [0.30, 0.87], respectively). NIPPV resulted in lesser incidence of bronchopulmonary dysplasia or mortality when compared to CPAP (0.74 [0.52, 0.98]). Nasal injury was lesser with HFNC compared to CPAP (0.15 [0.01, 0.60]).

CONCLUSIONS

Most effective primary mode of NRS in preterm neonates with RDS was NIPPV.

Cerebral oxygenation and circulatory parameters during pressure-controlled vs volume-targeted mechanical ventilation in extremely preterm infants

BACKGROUND

Respiratory distress syndrome (RDS) is the most common cause of respiratory failure of infants born prematurely with very low birth weight (VLBW). Essential elements of RDS management include ventilatory support and endotracheal administration of a surfactant.

OBJECTIVES

To assess the effect of volume-targeted compared to pressure-controlled mechanical ventilation (MV) on circulatory parameters and cerebral oxygenation StO2 in extremely preterm infants.

MATERIAL AND METHODS

This prospective, cross-over trial enrolled neonates born before 28 weeks of gestation. The patients were ventilated for 3 h in pressure-controlled assist-control (PC-AC) mode, followed by 3 h of volume-guarantee assist-control ventilation (VG-AC). Pulse oximetry (saturation (SpO2) and heart rate (HR)), near-infrared spectroscopy (NIRS), StO2, and electrical cardiometry (EC) were used in monitoring of the patients.

RESULTS

Twenty preterm infants with a mean gestational age of 26 weeks were studied. The patients' mean postnatal age was 7.7 days. The SpO2 values and HR were comparable during PC-AC and VG-AC. The mean values of peak inspiratory pressure (PIP), mean airway pressure (MAP) and expiratory tidal volume (VTE) were lower, while the respiratory rate (RR) was higher during PC-VG. There were no significant differences in the mean values of StO2, but based on a comparison of the standard deviations (SD) the StO2 variability was significantly lower during VG-AC. The circulatory parameters were comparable.

CONCLUSIONS

The StO2 is more stable during VG than PC ventilation. These findings support the use of VG mode in premature infants.

European Resuscitation Council COVID-19 guidelines executive summary

Coronavirus disease 2019 (COVID-19) has had a substantial impact on the incidence of cardiac arrest and survival. The challenge is to find the correct balance between the risk to the rescuer when undertaking cardiopulmonary resuscitation (CPR) on a person with possible COVID-19 and the risk to that person if CPR is delayed. These guidelines focus specifically on patients with suspected or confirmed COVID-19. The guidelines include the delivery of basic and advanced life support in adults and children and recommendations for delivering training during the pandemic. Where uncertainty exists treatment should be informed by a dynamic risk assessment which may consider current COVID-19 prevalence, the person’s presentation (e.g. history of COVID-19 contact, COVID-19 symptoms), likelihood that treatment will be effective, availability of personal protective equipment (PPE) and personal risks for those providing treatment. These guidelines will be subject to evolving knowledge and experience of COVID-19. As countries are at different stages of the pandemic, there may some international variation in practice.

A Comparison of UK Preterm Anthropometric Charts and INTERGROWTH-21st: Is It Time to Change Growth Charts?

BACKGROUND

Current practice in the UK is to plot premature infant anthropometric measurements on Neonatal and Infant Close Monitoring (NICM) reference charts. These charts have several known limitations. The INTERGROWTH-21st Project has recently produced international ante- and postnatal growth standards. Exact knowledge of growth centiles allows clinicians to accurately assess infant nutritional requirements.

OBJECTIVE

To compare target centile measurements between INTERGROWTH-21st and UK NICM growth charts for premature infants.

METHOD

Anthropometric measurements (weight and head circumference) of a convenience sample of neonates born between 24 and 32 weeks of gestation were analysed retrospectively. Measurements were collected across three time points and plotted on both the NICM and INTERGROWTH-21st growth charts. The respective centiles were compared and analysed by paired-sample t test, Wilcoxon rank test analysis, and multilevel mixed-effect linear regression models.

RESULTS

Centiles for weight and head circumference measurements of 96 infants plotted on INTERGROWTH-21st charts were significantly greater than their corresponding UK charts at all three time points. For weight, the average difference between the two charts varied from 9.1 to 16.4 centiles. The difference between the two charts was greater for female than male infants by up to 6.9 centiles (95% CI 10.1-3.8).

CONCLUSION

Existing UK NICM reference charts are significantly different to the growth standards of INTERGROWTH-21st. The choice of which growth chart to adopt in the UK could have important consequences on premature infants' future adult health and therefore requires further prospective observational studies with larger data sets including length measurements and more comprehensive population characteristics.

Neonatal Resuscitation Where the Mother Has a Suspected or Confirmed Novel Coronavirus (SARS-CoV-2) Infection: Suggestion for a Pragmatic Action Plan

Coronavirus disease 2019 (COVID-19), caused by the novel SARS-CoV-2 virus, is rapidly spreading across the world. As the number of infections increases, those of infected pregnant women and children will rise as well. Controversy exists whether COVID-19 can be transmitted in utero and lead to disease in the newborn. As this chance cannot be ruled out, strict instructions for the management of mothers and newborn infants are mandatory. This perspective aims to be a practical support tool for the planning of delivery and neonatal resuscitation of infants born by mothers with suspected or confirmed COVID-19 infection.

Caffeine in preterm infants: where are we in 2020?

The incidence of preterm birth is increasing, leading to a growing population with potential long-term pulmonary complications. Apnoea of prematurity (AOP) is one of the major challenges when treating preterm infants; it can lead to respiratory failure and the need for mechanical ventilation. Ventilating preterm infants can be associated with severe negative pulmonary and extrapulmonary outcomes, such as bronchopulmonary dysplasia (BPD), severe neurological impairment and death. Therefore, international guidelines favour non-invasive respiratory support. Strategies to improve the success rate of non-invasive ventilation in preterm infants include pharmacological treatment of AOP. Among the different pharmacological options, caffeine citrate is the current drug of choice. Caffeine is effective in reducing AOP and mechanical ventilation and enhances extubation success; it decreases the risk of BPD; and is associated with improved cognitive outcome at 2 years of age, and pulmonary function up to 11 years of age. The commonly prescribed dose (20 mg·kg⁻¹ loading dose, 5–10 mg·kg⁻¹ per day maintenance dose) is considered safe and effective. However, to date there is no commonly agreed standardised protocol on the optimal dosing and timing of caffeine therapy. Furthermore, despite the wide pharmacological safety profile of caffeine, the role of therapeutic drug monitoring in caffeine-treated preterm infants is still debated. This state-of-the-art review summarises the current knowledge of caff­eine therapy in preterm infants and highlights some of the unresolved questions of AOP. We speculate that with increased understanding of caffeine and its metabolism, a more refined respiratory management of preterm infants is feasible, leading to an overall improvement in patient outcome.

Caffeine is the current drug of choice to prevent and treat apnoea of prematurity. There is no agreed protocol on the optimal timing and dosage of caffeine therapy for preterm babies. Data on caffeine metabolism may optimise individualised therapy.http://bit.ly/2LMuJPY

Randomised cross-over study of automated oxygen control for preterm infants receiving nasal high flow

OBJECTIVE

To evaluate a prototype automated controller (IntellO₂) of the inspired fraction of oxygen (FiO₂) in maintaining a target range of oxygen saturation (SpO₂) in preterm babies receiving nasal high flow (HF) via the Vapotherm Precision Flow.

DESIGN

Prospective two-centre order-randomised cross-over study.

SETTING

Neonatal intensive care units.

PATIENTS

Preterm infants receiving HF with FiO₂ ≥25%.

INTERVENTION

Automated versus manual control of FiO₂ to maintain a target SpO₂ range of 90%-95% (or 90%-100% if FiO₂=21%).

MAIN OUTCOME MEASURES

The primary outcome measure was per cent of time spent within target SpO₂ range. Secondary outcomes included the overall proportion and durations of SpO₂ within specified hyperoxic and hypoxic ranges and the number of in-range episodes per hour.

RESULTS

Data were analysed from 30 preterm infants with median (IQR) gestation at birth of 26 (24-27) weeks, study age of 29 (18-53) days and study weight 1080 (959-1443) g. The target SpO₂ range was achieved 80% of the time on automated (IntellO₂) control (IQR 70%-87%) compared with 49% under manual control (IQR 40%-57%; p<0.0001). There were fewer episodes of SpO₂ below 80% lasting at least 60 s under automated control (0 (IQR 0-1.25)) compared with manual control (5 (IQR 2.75-14)). There were no differences in the number of episodes per hour of SpO₂ above 98% (4.5 (IQR 1.8-8.5) vs 5.5 (IQR 1.9-14); p=0.572) between the study arms.

CONCLUSIONS

The IntellO₂ automated oxygen controller maintained patients in the target SpO₂ range significantly better than manual adjustments in preterm babies receiving HF.

TRIAL REGISTRATION NUMBER

National surveys of UK and Italian neonatal units highlighted significant differences in the use of non-invasive respiratory support

AIM

This study compared how non-invasive respiratory support (NRS) was provided in neonatal units in Italy and the UK.

METHODS

An NRS questionnaire was sent to tertiary neonatal centres, identified by national societies, from November 2015 to May 2016.

RESULTS

Responses were received from 49/57 (86%) UK units and 103/115 (90%) Italian units. NRS was started in the delivery room by 61% of UK units and 85% of Italian units. In neonatal intensive care units, 33% of UK units used nasal high-flow therapy (HFT) as primary support, compared to 3% in Italy. Nasal continuous positive airway pressure (CPAP) was used in 57% of UK units and 90% of Italian units. The commonest starting flow rate on nasal HFT for term and preterm infants was 6 L/min in the UK, while Italian units mainly used this flow for term infants. In the UK, 67% of units decreased nasal HFT by 1 L/min per day. In Italy, infants on nasal CPAP were weaned by 1 cm H₂ O per day in 39% of units.

CONCLUSION

The way that NRS was managed for very preterm infants differed between the UK and Italy, reflecting a lack of evidence on optimal NRS and the use of local protocols.

Initial Oxygen Use for Preterm Newborn Resuscitation: A Systematic Review With Meta-analysis

: media-1vid110.1542/5839981895001PEDS-VA_2018-1828Video Abstract CONTEXT: The International Liaison Committee on Resuscitation prioritized to review the initial fraction of inspired oxygen (Fio₂) during the resuscitation of preterm newborns.

OBJECTIVES

This systematic review and meta-analysis provides the scientific summary of initial Fio₂ in preterm newborns (<35 weeks' gestation) who receive respiratory support at birth.

DATA SOURCES

Medline, Embase, Evidence-Based Medicine Reviews, and Cumulative Index to Nursing and Allied Health Literature were searched between January 1, 1980 and August 10, 2018.

STUDY SELECTION

Studies were selected by pairs of independent reviewers in 2 stages with a Cohen's κ of 0.8 and 1.0.

DATA EXTRACTION

Pairs of independent reviewers extracted data, appraised the risk of bias (RoB), and assessed Grading of Recommendations Assessment, Development and Evaluation certainty.

RESULTS

Ten randomized controlled studies and 4 cohort studies included 5697 patients. There are no statistically significant benefits of or harms from starting with lower compared with higher Fio₂ in short-term mortality (n = 968; risk ratio = 0.83 [95% confidence interval 0.50 to 1.37]), long-term mortality, neurodevelopmental impairment, or other key preterm morbidities. A sensitivity analysis in which 1 study with a high RoB was excluded failed to reveal a reduction in mortality with initial low Fio₂ (n = 681; risk ratio = 0.63 [95% confidence interval 0.38 to 1.03]).

LIMITATIONS

The Grading of Recommendations Assessment, Development and Evaluation certainty of evidence was very low for all outcomes due to RoB, inconsistency, and imprecision.

CONCLUSIONS

The ideal initial Fio₂ for preterm newborns is still unknown, although the majority of newborns ≤32 weeks' gestation will require oxygen supplementation.

Surfactant Administration via Thin Catheter: A Practical Guide

Exogenous surfactant replacement is the most effective evidence-based therapy for respiratory distress syndrome in preterm infants. The mode of administration has evolved in the last decade towards less invasive techniques that aim to effectively provide an adequate dose of surfactant, while allowing spontaneous respiration to continue, and with the support of continuous positive airway pressure. Surfactant delivery via aerosolisation, pharyngeal instillation, and laryngeal mask are being actively pursued in research, but have not yet been adopted to any significant degree in clinical practice. Surfactant administration via thin catheter, on the other hand, is becoming more widely used in neonatal intensive care units worldwide and is now an acknowledged alternative to the standard mode of surfactant delivery. Different devices, including nasogastric tubes, vascular catheters, and purpose-built surfactant instillation catheters are used. We present here a contemporary review of surfactant administration via thin catheter, in a practical guide format that reflects the individual and collective scientific opinions of the clinicians who participated in formulating the guide.

Room Air for Initiating Term Newborn Resuscitation: A Systematic Review With Meta-analysis

: media-1vid110.1542/5839981898001PEDS-VA_2018-1825Video Abstract CONTEXT: The International Liaison Committee on Resuscitation prioritized to rigorously review the initial fraction of inspired oxygen (Fio₂) during resuscitation of newborns.

OBJECTIVE

This systematic review and meta-analysis provides the scientific summary of initial Fio₂ in term and late preterm newborns (≥35 weeks' gestation) who receive respiratory support at birth.

DATA SOURCES

Medline, Embase, Evidence Based Medicine Reviews, and Cumulative Index to Nursing and Allied Health Literature were searched between January 1, 1980 and August 10, 2018.

STUDY SELECTION

Studies were selected by pairs of independent reviewers in 2 stages, with a Cohen's κ of 0.8 and 1.0.

DATA EXTRACTION

Pairs of independent reviewers extracted data, appraised risk of bias, and assessed Grading of Recommendations Assessment, Development and Evaluation certainty of evidence.

RESULTS

Five randomized controlled trials (RCTs) and 5 quasi RCTs included 2164 patients. Room air (Fio₂ 0.21) was associated with a statistically significant benefit in short-term mortality compared with 100% oxygen (Fio₂ 1.0) (7 RCTs; n = 1469; risk ratio [RR] = 0.73; 95% confidence interval [CI]: 0.57 to 0.94). No significant differences were observed in neurodevelopmental impairment (2 RCTs; n = 360; RR = 1.41; 95% CI: 0.77 to 2.60) or hypoxic-ischemic encephalopathy (5 RCTs; n = 1315; RR = 0.89; 95% CI: 0.68 to 1.18).

LIMITATIONS

The Grading of Recommendations Assessment, Development and Evaluation certainty of evidence was low for short-term mortality and hypoxic-ischemic encephalopathy and very low for neurodevelopmental impairment.

CONCLUSIONS

Room air has a 27% relative reduction in short-term mortality compared with Fio₂ 1.0 for initiating neonatal resuscitation ≥35 weeks' gestation.

Use of Intraosseous Needles in Neonates: A Systematic Review

BACKGROUND

The use of intraosseous (IO) access during resuscitation is widely accepted and promoted in paediatric medicine but features less prominently in neonatal training. Whilst umbilical venous catheterization (UVC) is a reliable method of delivering emergency drugs and fluids, it is not always achievable in a timely manner. IO access warrants exploration as an alternative.

AIM

Conduct a systematic review of existing literature to examine the evidence for efficacy and safety of IO devices in neonatal patients, from birth to discharge.

METHOD

A search of PubMed, Ovid, Medline, and Embase was carried out. Abstracts were screened for relevance to focus on neonatal-specific literature and studies which carried out separate analyses for neonates (infants <28 days of age or resident on a neonatal unit).

RESULTS

One case series and 12 case reports describe IO device insertion into 41 neonates, delivering a variety of drugs, including adrenaline (epinephrine) and volume resuscitation. Complications range from none to severe. Cadaveric studies show that despite a small margin for error, IO devices can be correctly sited in neonates. Simulation studies suggest that IO devices may be faster and easier to site than UVC, even in experienced hands.

CONCLUSION

IO access should be available on neonatal units and considered for early use in neonates where other access routes have failed. Appropriate training should be available to staff in addition to existing life support and UVC training. Further studies are required to assess the optimal device, position, and whether medication can be delivered IO as effectively as by UVC. If IO devices provide a faster method of delivering adrenaline effectively than UVC, this may lead to changes in neonatal resuscitation practice.

The Laryngeal Mask Airway and Its Use in Neonatal Resuscitation: A Critical Review of Where We Are in 2017/2018

Studies using videotape recordings and respiratory function monitoring have shown that both face mask (FM) application and endotracheal tube (ETT) placement represent a challenge for resuscitators. Hence, there is a strong need for devices that can largely be used independently of individual operator training levels, in order to ensure more reliable support in time-critical situations, such as neonatal resuscitation. The laryngeal mask airway device (LMA) has evolved as a potentially very valuable tool. We conducted a systematic review of studies evaluating the use of the LMA in neonatal resuscitation. An electronic literature search of large medical databases was performed to identify relevant publications on the use of an LMA during neonatal delivery room (DR) resuscitation. Following a rigorous systematic review, we identified a total of 7 randomized controlled trials with results indicating that initial respiratory management of newborn infants with an LMA is feasible for a defined subgroup of infants, but the evidence is still insufficient to recommend the LMA instead of FM ventilation in the DR. There is, in particular, a dearth of evidence of the use of LMA in neonates born before 34 weeks' gestational age or weighing <1,500 g at birth. There were no reports on significant complications following the use of LMA; however, evidence is still limited regarding short- and long-term outcomes. We conclude that the limited currently available evidence suggests that the use of the LMA is a feasible and safe alternative to mask ventilation of late preterm and term infants in the DR. The potential use of LMA resuscitation, in particular for low-gestation and low-birth-weight infants, needs further study.

When Helping Babies Breathe Is Not Enough: Designing a Novel, Mid-Level Neonatal Resuscitation Algorithm for Médecins Sans Frontières Field Teams Working in Low-Resource Hospital Settings

BACKGROUND

Neonatal resuscitation (NR) combines a set of life-saving interventions in order to stabilize compromised newborns at birth or when critically ill. Médecins Sans Frontières/Doctors Without Borders (MSF), as an international medical-humanitarian organization working particularly in low-resource settings (LRS), assisted over 250,000 births in obstetric and newborn care aid projects in 2016 and provides thousands of newborn resuscitations annually. The Helping Babies Breathe (HBB) program has been used as formal guidance for basic resuscitation since 2012. However, in some MSF projects with the capacity to provide more advanced NR interventions but a lack of adapted guidance, staff have felt prompted to create their own advanced algorithms, which runs counter to the organization's aim for standardized protocols in all aspects of its care.

OBJECTIVES

The aim is to close a significant gap in neonatal care provision in LRS by establishing consensus on a protocol that would guide MSF field teams in their practice of more advanced NR.

METHODS

An independent committee of international experts was formed and met regularly from June 2016 to agree on the content and design of a new NR algorithm.

RESULTS

Consensus was reached on a novel, mid-level NR algorithm in April 2017. The algorithm was accepted for use by MSF Operational Center Paris.

CONCLUSION

This paper contributes to the literature on decision-making in the development of cognitive aids. The authors also highlight how critical gaps in healthcare delivery in LRS can be addressed, even when there is limited evidence to guide the process.

Ingeborg Syllm-Rapoport (1912-2017): An Exemplary Life for Children and Paediatrics

Ingeborg Syllm-Rapoport, the first Chair in neonatology in Europe, passed away on March 23. Her biography illustrates how medical and scientific work has been influenced by social, ideological, and economic frames and boundaries in the 20th century. Regarded as a "Half-Jew" by the Nazi racist laws, she was denied her medical doctorate. She went to the USA, where she trained in paediatrics and met her husband, the biochemist Samuel Mitja Rapoport. During the "McCarthy Era" both were persecuted as communists. They returned to Europe and became two of the most influential figures at the Charité Hospital in East Berlin. She had to wait until 2015 to finally undergo the doctoral examination at the age of 102 years, making her the oldest person in history to receive a doctorate. We describe Syllm-Rapoport's life and the challenges she had to face living in several countries under different political systems in the 20th century.

Key paediatric messages from the 2016 European Respiratory Society International Congress

In this article, the Group Chairs of the Paediatric Assembly of the European Respiratory Society (ERS) highlight some of the most interesting abstracts presented at the 2016 ERS International Congress, which was held in London.

When should resuscitation at birth cease?

It is rare for newborn infants to require prolonged resuscitation at birth. While there are detailed national and international guidelines on when and how to provide resuscitation to newborns, there is little existing guidance on when newborn resuscitation should be stopped. In this paper we review current guidance surrounding adult, paediatric and neonatal resuscitation as well as recent evidence of outcome for newborn infants requiring prolonged resuscitation. We discuss the ethical principles that can potentially guide decisions surrounding resuscitation and post-resuscitation care. We also propose a structured approach to stopping resuscitation.
