Randomised study of a new inline respiratory function monitor (Juno) to improve mask seal and delivered ventilation with neonatal manikins. Arch Dis Child Fetal Neonatal Ed 2024; 109:535-541. [PMID: 38336472 PMCID: PMC11347194 DOI: 10.1136/archdischild-2023-326256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 01/18/2024] [Indexed: 02/12/2024]
Abstract
BACKGROUND Respiratory function monitors (RFMs) have been used extensively in manikin and infant studies yet have not become the standard of training. We report the outcomes of a new portable, lightweight RFM, the Juno, designed to show mask leak and deflation tidal volume to assist in positive pressure ventilation (PPV) competency training using manikins. METHODS Two leak-free manikins (preterm and term) were used. Participants provided PPV to manikins using two randomised devices, self-inflating bag (SIB) and T-piece resuscitator (TPR), with Juno display initially blinded then unblinded in four 90 s paired sequences, aiming for adequate chest wall rise and target minimal mask leak with appropriate target delivered volume when using the monitor. RESULTS 49 experienced neonatal staff delivered 15 569 inflations to the term manikin and 14 580 inflations to the preterm. Comparing blinded to unblinded RFM display, there were significant reductions in all groups in the number of inflations out of target range volumes (preterm: SIB 22.6-6.6%, TPR 7.1-4.2% and term: SIB 54.8-37.8%, TPR 67.2-63.8%). The percentage of mask leak inflations >60% was reduced in preterm: SIB 20.7-7.2%, TPR 23.4-7.4% and in term: SIB 8.7-3.6%, TPR 23.5-6.2%). CONCLUSIONS Using the Juno monitor during simulated resuscitation significantly improved mask leak and delivered ventilation among otherwise experienced staff using preterm and term manikins. The Juno is a novel RFM that may assist in teaching and self-assessment of resuscitation PPV technique.

Optimization of manual ventilation quality using respiratory function monitoring in neonates: A two-phase intervention trial. Resuscitation 2024:110345. [PMID: 39097079 DOI: 10.1016/j.resuscitation.2024.110345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 07/09/2024] [Accepted: 07/28/2024] [Indexed: 08/05/2024]
Abstract
OBJECTIVE The aim of this study was the evaluation of the impact of a respiratory function monitor (RFM, Neo100, Monivent AB, Gothenburg, Sweden) on the quality of ventilation in neonates. METHODS This single-center two-phase intervention study was conducted at the Neonatal Intensive Care Unit and the delivery room of the Medical University of Vienna. Patients with clinical need for positive pressure ventilation were included in either of two consecutive study phases: (i) patients were ventilated with a hidden RFM (control) or (ii) visible RFM (intervention) during manual positive pressure ventilations. The duration of each phase was approximately six months. The primary outcome was the percentage of ventilations within a tidal volume range of 4-8 ml/kg (pVTe). RESULTS A total of 90 patients (GA 22-66 weeks) were included. The primary outcome was significantly higher in the intervention group with a visible RFM (53.7%, SD 22.6) than in the control group without the monitor (37.3%, SD 20.5); (p < 0.001, mean difference [i.e., change in percentage points]: 16.95% CI: 7.4-35). In terms of secondary outcomes, excessive tidal volumes (>8ml/kg), potentially associated with an increased risk of brain injury, could be significantly reduced when a RFM was visible during ventilation (10.9% [IQR 26.4] vs. 29.5% [IQR 38.1]; p = 0.004). Furthermore, mask leakage could be significantly decreased (37.3% [SD 22.7] vs. 52.7% [SD 23.0]; p = 0.002). CONCLUSION Our results suggest that the clinical application of a RFM for manual ventilation of preterm and term infants leads to a significant improvement in ventilation parameters.

Abstract
BACKGROUND To compare tidal volume (VT) delivery with compliance at 0.5 and 1.5 mL/cmH2O using four different ventilation (PPV) devices (i.e., self-inflating bag (SIB), T-Piece resuscitator, Next Step (a novel Neonatal Resuscitator), and Fabian ventilator (conventional neonatal ventilator) using a neonatal piglet model. DESIGN/METHODS Randomized experimental animal study using 10 mixed-breed neonatal piglets (1-3 days; 1.8-2.4 kg). Piglets were anesthetized, intubated, instrumented, and randomized to receive positive pressure ventilation (PPV) for one minute with a SIB with or without a respiratory function monitor (RFM), T-Piece resuscitator with or without an RFM, Next Step, and Fabian Ventilator with both compliance levels. Compliance changes were achieved by placing a wrap around the piglets' chest and tightened it. Our primary outcome was targeted VT delivery of 5 mL/kg at 0.5 and 1.5 mL/cmH2O lung compliance. RESULTS At 0.5 mL/cmH2O compliance, the mean(SD) expired VT with the Next Step was 5.1(0.2) mL/kg compared to the Fabian 4.8(0.5) mL/kg, SIB 8.9(3.6) mL/kg, SIB + RFM 4.5(1.8) mL/kg, T-Piece 7.4(4.3) mL/kg, and T-Piece+RFM 6.4(3.1) mL/kg. At 1.5 mL/cmH2O compliance, the mean(SD) expired VT with the Next Step was 5.2(0.6) mL/kg compared to the Fabian 4.4(0.7) mL/kg, SIB 12.1(5.3) mL/kg, SIB + RFM 9.4(3.9) mL/kg, T-Piece 8.6(1.5) mL/kg, and T-Piece+RFM 6.5 (1.6) mL/kg. CONCLUSION The Next Step provides consistent VT during PPV, which is comparable to a mechanical ventilator. IMPACT Current guidelines recommend fixed peak inflation pressure in resuscitation, linked to lung and brain injury. The Next Step Neonatal Resuscitator, a cost-effective device, offers volume-targeted positive pressure ventilation with consistent tidal volumes. With two different compliances, the Next Step Neonatal Resuscitator delivered a consistent tidal volume which was similar to a mechanical ventilator. The Next Step Neonatal Resuscitator outperformed self-inflating bags and T-Pieces in delivering targeted tidal volumes. The Next Step Neonatal Resuscitator could be an alternative ventilation device for neonatal resuscitation.

Abstract
BACKGROUND A major proportion of preterm neonates require positive pressure ventilation (PPV) immediately after delivery. PPV may be administered through a face mask (FM) or nasal prongs. Current literature indicates that either of these are associated with similar outcomes. SUMMARY Nonetheless, FM remains the most utilized and the best choice. However, most available FM sizes are too large for extremely preterm infants, which leads to mask leak and ineffective PPV. Challenges to providing effective PPV include poor respiratory drive, complaint chest wall, weak thoracic muscle, delayed liquid clearance, and surfactant deficiency in preterm infants. Mask leak, airway obstruction, poor technique, and inappropriate size are correctable causes of ineffective PPV. Visual assessment of chest rise is often used to assess the efficacy of PPV. However, its accuracy is debatable. Though end tidal CO2 may adjudge the effectiveness of PPV, clinical studies are limited. The compliance of a preterm lung is highly dynamic. The inflating pressure set on T-piece is constant throughout the resuscitation, but the lung volume and dynamics changes with every breath. This leads to huge fluctuations of tidal volume delivery and can trigger inflammatory cascade in preterm infants leading to brain and lung injury. Respiratory function monitoring in the delivery room has potential for guiding and optimizing delivery room resuscitation. This is, however, limited by high costs, complex information that is difficult to interpret during resuscitation, and absence of clinical trials. KEY MESSAGES This review summarizes the existing literature on PPV in preterm infants, the various aspects related to it such as the pathophysiology, interfaces, devices utilized to deliver it, appropriate technique, emerging technologies, and future directions.

Abstract
Neonatal care has made significant advances in the last few decades. As a result, mortality and morbidity in high-risk infants, such as extremely preterm infants or those infants with birth-related brain injury, has reduced significantly. Many of these advances have been facilitated or delivered through development of medical technologies allowing clinical teams to be better supported with the care they deliver or provide new therapies and diagnostics to improve management. The delivery of neonatal intensive care requires the provision of medical technologies that are easy to use, reliable, accurate and ideally developed for the unique needs of the newborn population. Many technologies have been developed and commercialised following adult trials without ever being studied in neonatal patients despite the unique characteristics of this population. Increasingly, funders and industry are recognising this major challenge which has resulted in initiatives to develop new ideas from concept through to clinical care. This review explores some of the key medical technologies used in neonatal care and the evidence to support their adoption to improve outcomes. A number of devices have yet to realise their full potential and will require further development to optimise and find their ideal target population and clinical benefit. Examples of emerging technologies, which may soon become more widely used, are also discussed. As neonatal care relies more on medical technologies, we need to be aware of the impact on care pathways, especially from a human factors approach, the associated costs and subsequent benefits to patients alongside the supporting evidence.

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
The fetal-to-neonatal transition poses an extraordinary challenge for extremely low birth weight (ELBW) infants, and postnatal stabilization in the delivery room (DR) remains challenging. The initiation of air respiration and the establishment of a functional residual capacity are essential and often require ventilatory support and oxygen supplementation. In recent years, there has been a tendency towards the soft-landing strategy and, subsequently, non-invasive positive pressure ventilation has been generally recommended by international guidelines as the first option for stabilizing ELBW in the delivery room. On the other hand, supplementation with oxygen is another cornerstone of the postnatal stabilization of ELBW infants. To date, the conundrum concerning the optimal initial inspired fraction of oxygen, target saturations in the first golden minutes, and oxygen titration to achieve desired stability saturation and heart rate values has not yet been solved. Moreover, the retardation of cord clamping together with the initiation of ventilation with the patent cord (physiologic-based cord clamping) have added additional complexity to this puzzle. In the present review, we critically address these relevant topics related to fetal-to-neonatal transitional respiratory physiology, ventilatory stabilization, and oxygenation of ELBW infants in the delivery room based on current evidence and the most recent guidelines for newborn stabilization.

Resuscitators' opinions on using a respiratory function monitor during neonatal resuscitation. Acta Paediatr 2023; 112:63-68. [PMID: 36177808 PMCID: PMC10092741 DOI: 10.1111/apa.16559] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 09/06/2022] [Accepted: 09/29/2022] [Indexed: 12/13/2022]
Abstract
AIM The aim of this study was to assess the resuscitators' opinions of the usefulness and clinical value of using a respiratory function monitor (RFM) when resuscitating extremely preterm infants with positive pressure ventilation. METHODS The link to an online survey was sent to 106 resuscitators from six countries who were involved in a multicentre trial that compared the percentage of inflations within a predefined target range with and without the RFM. The resuscitators were asked to assess the usefulness and clinical value of the RFM. The survey was online for 4 months after the trial ended in May 2019. RESULTS The survey was completed by 74 (70%) resuscitators of which 99% considered the RFM to be helpful during neonatal resuscitation and 92% indicated that it influenced their decision-making. The majority (76%) indicated that using the RFM improved their practice and made resuscitation more effective, even when the RFM was not available. Inadequate training was the key issue that limited the effectiveness of the RFM: 45% felt insufficiently trained, and 78% felt more training in using and interpreting the RFM would have been beneficial. CONCLUSION Resuscitators considered the RFM to be helpful to guide neonatal resuscitation, but sufficient training was required to achieve the maximum benefit.

Abstract
Aim Positive pressure ventilation via a facemask is critical in neonatal resuscitation, but frequently results in mask leak, obstruction, and inadequate respiratory support. This systematic review aimed to determine whether the display of respiratory function monitoring improved resuscitation or clinical outcomes. Methods Randomized controlled trials comparing outcomes when respiratory function monitoring was displayed versus not displayed for newborns requiring positive pressure ventilation at birth were selected and from databases (last search August 2022), and assessed for risk of bias using Cochrane Risk of Bias Tools for randomized control trials. The study was registered in the Prospective Register of Systematic Reviews. Grading of Recommendations, Assessment, Development and Evaluations was used to assess the certainty of evidence. Treatment recommendations were approved by the Neonatal Life Support Task Force of the International Liaison Committee on Resuscitation. Results reported primary and secondary outcomes and included resuscitation and clinical outcomes. Results Of 2294 unique articles assessed for eligibility, three randomized controlled trials were included (observational studies excluded) (n = 443 patients). For predefined resuscitation and clinical outcomes, these studies either did not report the primary outcome (time to heart rate ≥ 100 bpm from birth), had differing reporting methods (achieving desired tidal volumes, significant mask leak) or did not find significant differences (intubation rate, air leaks, death before hospital discharge, severe intraventricular hemorrhage, chronic lung disease). Limitations included limited sample size for critical outcomes, inconsistent definitions amongst studies and unreported long-term outcomes. Conclusion Although respiratory function monitoring has been utilized in clinical care, there is currently insufficient evidence to suggest its benefit for newborn infants receiving respiratory support for resuscitation at birth. Registration PROSPERO CRD42021278169 (registered November 27, 2021). Funding The International Liaison Committee on Resuscitation provided support that included access to software platforms and teleconferencing.

Abstract
IMPORTANCE Animal and observational human studies report that delivery of excessive tidal volume (VT) at birth is associated with lung and brain injury. Using a respiratory function monitor (RFM) to guide VT delivery might reduce injury and improve outcomes. OBJECTIVE To determine whether use of an RFM in addition to clinical assessment versus clinical assessment alone during mask ventilation in the delivery room reduces in-hospital mortality and morbidity of infants <37 weeks' gestation. STUDY SELECTION Randomised controlled trials (RCTs) comparing RFM in addition to clinical assessment versus clinical assessment alone during mask ventilation in the delivery room of infants born <37 weeks' gestation. DATA ANALYSIS Risk of bias was assessed using Covidence Collaboration tool and pooled into a meta-analysis using a random-effects model. The primary outcome was death prior to discharge. MAIN OUTCOME Death before hospital discharge. RESULTS Three RCTs enrolling 443 infants were combined in a meta-analysis. The pooled analysis showed no difference in rates of death before discharge with an RFM versus no RFM, relative risk (RR) 95% (CI) 0.98 (0.64 to 1.48). The pooled analysis suggested a significant reduction for brain injury (a combination of intraventricular haemorrhage and periventricular leucomalacia) (RR 0.65 (0.48 to 0.89), p=0.006) and for intraventricular haemorrhage (RR 0.69 (0.50 to 0.96), p=0.03) in infants receiving positive pressure ventilation with an RFM versus no RFM. CONCLUSION In infants <37 weeks, an RFM in addition to clinical assessment compared with clinical assessment during mask ventilation resulted in similar in-hospital mortality, significant reduction for any brain injury and intraventricular haemorrhage. Further trials are required to determine whether RFMs should be routinely available for neonatal resuscitation.

Abstract
OBJECTIVE To review the current state of the art of positive pressure ventilation (PPV) during resuscitation FINDINGS: The frequency of PPV during delivery room resuscitation varies across settings and gestational age subgroups. Goal targets and parameters for delivery room PPV remain undefined. The T-piece resuscitator provides the most consistent pressures during PPV and may improve clinical outcomes. The laryngeal mask may be an important alternative interface for PPV, but more data are needed to identify the optimal role of the supraglottic airway during PPV. No objective monitors of PPV have conclusively demonstrated improved outcomes to date. CONCLUSION More information, including real-world data from population-based studies, is needed to provide data-driven guidelines for positive pressure ventilation during neonatal transition after birth.

Abstract
Advances in neonatal care have resulted in improved outcomes for high-risk newborns with technologies playing a significant part although many were developed for the neonatal intensive care unit. The care provided in the delivery room (DR) during the first few minutes of life can impact short- and long-term neonatal outcomes. Increasingly, technologies have a critical role to play in the DR particularly with monitoring and information provision. However, the DR is a unique environment and has major challenges around the period of foetal to neonatal transition that need to be overcome when developing new technologies. This review focuses on current DR technologies as well as those just emerging and further over the horizon. We identify what key opinion leaders in DR care think of current technologies, what the important DR measures are to them, and which technologies might be useful in the future. We link these with key technologies including respiratory function monitors, electoral impedance tomography, videolaryngoscopy, augmented reality, video recording, eye tracking, artificial intelligence, and contactless monitoring. Encouraging funders and industry to address the unique technological challenges of newborn care in the DR will allow the continued improvement of outcomes of high-risk infants from the moment of birth. IMPACT: Technological advances for newborn delivery room care require consideration of the unique environment, the variable patient characteristics, and disease states, as well as human factor challenges. Neonatology as a speciality has embraced technology, allowing its rapid progression and improved outcomes for infants, although innovation in the delivery room often lags behind that in the intensive care unit. Investing in new and emerging technologies can support healthcare providers when optimising care and could improve training, safety, and neonatal outcomes.

Tidal volumes and pressures delivered by the NeoPuff T-piece resuscitator during resuscitation of term newborns. Resuscitation 2021; 170:222-229. [PMID: 34915085 DOI: 10.1016/j.resuscitation.2021.12.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 12/02/2021] [Accepted: 12/07/2021] [Indexed: 12/16/2022]
Abstract
AIM T-piece resuscitators are commonly used for respiratory support during newborn resuscitation. This study aimed to describe delivered pressures and tidal volumes when resuscitating term newborns immediately after birth, using the NeoPuff T-piece resuscitator. METHOD Observational study from June 2019 through March 2021 at Stavanger University Hospital, Norway, including term newborns ventilated with a T-piece resuscitator after birth, with consent to participate. Ventilation parameters of the first 100 inflations from each newborn were recorded by respiration monitors and divided into an early (inflation 1-20) and a late (inflation 21-100) phase. RESULTS Of the 7730 newborns born, 232 term newborns received positive pressure ventilation. Of these, 129 newborns were included. In the early and the late phase, the median (interquartile range) peak inflating pressure was 30 (28-31) and 30 (27-31) mbar, and tidal volume was 4.5 (1.6-7.8) and 5.7 (2.2-9.8) ml/kg, respectively. Increased inflation times were associated with an increase in volume before plateauing at an inflation time of 0.41 s in the early phase and 0.50 s in the late phase. Inflation rates exceeding 32 per minute in the early phase and 41 per minute in the late phase were associated with lower tidal volumes. CONCLUSION There was a substantial variation in tidal volumes despite a relatively stable peak inflating pressure. Delivered tidal volumes were at the lower end of the recommended range. Our results indicate that an inflation time of approximately 0.5 s and rates around 30-40 per minute are associated with the highest delivered tidal volumes.

Abstract
Mechanical ventilation can be life-saving for the premature infant, but is often injurious to immature and underdeveloped lungs. Lung injury is caused by atelectrauma, oxygen toxicity, and volutrauma. Lung protection must include appropriate lung recruitment starting in the delivery suite and throughout mechanical ventilation. Strategies include open lung ventilation, positive end-expiratory pressure, and volume-targeted ventilation. Respiratory function monitoring, such as capnography and ventilator graphics, provides clinicians with continuous real-time information and an adjunct to optimize lung-protective ventilatory strategies. Further research is needed to assess which lung-protective strategies result in a decrease in long-term respiratory morbidity.

Abstract
AIM To determine whether the use of a respiratory function monitor (RFM) during PPV of extremely preterm infants at birth, compared with no RFM, leads to an increase in percentage of inflations with an expiratory tidal volume (Vte) within a predefined target range. METHODS Unmasked, randomised clinical trial conducted October 2013 - May 2019 in 7 neonatal intensive care units in 6 countries. Very preterm infants (24-27 weeks of gestation) receiving PPV at birth were randomised to have a RFM screen visible or not. The primary outcome was the median proportion of inflations during manual PPV (face mask or intubated) within the target range (Vte 4-8 mL/kg). There were 42 other prespecified monitor measurements and clinical outcomes. RESULTS Among 288 infants randomised (median (IQR) gestational age 26+2 (25+3-27+1) weeks), a total number of 51,352 inflations were analysed. The median (IQR) percentage of inflations within the target range in the RFM visible group was 30.0 (18.0-42.2)% vs 30.2 (14.8-43.1)% in the RFM non-visible group (p = 0.721). There were no differences in other respiratory function measurements, oxygen saturation, heart rate or FiO2. There were no differences in clinical outcomes, except for the incidence of intraventricular haemorrhage (all grades) and/or cystic periventricular leukomalacia (visible RFM: 26.7% vs non-visible RFM: 39.0%; RR 0.71 (0.68-0.97); p = 0.028). CONCLUSION In very preterm infants receiving PPV at birth, the use of a RFM, compared to no RFM as guidance for tidal volume delivery, did not increase the percentage of inflations in a predefined target range.
