Non-Invasive Ventilatory Support in Preterm Neonates in the Delivery Room and the Neonatal Intensive Care Unit: A Short Narrative Review of What We Know in 2024. Neonatology 2024:1-8. [PMID: 39173610 DOI: 10.1159/000540601] [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: 05/10/2024] [Accepted: 07/22/2024] [Indexed: 08/24/2024]
Abstract
BACKGROUND Guidelines recommend non-invasive ventilatory (NIV) support as first-line respiratory support mode in preterm infants as NIV is superior to intubation and mechanical ventilation in preventing death or bronchopulmonary dysplasia. However, with an ever-expanding variety of NIV modes available, there is much debate about which NIV modality should ideally be used, how, and when. The aims of this work were to summarise the evidence on different NIV modalities for both primary and secondary respiratory support: nCPAP, nasal high-flow therapy (nHFT), and nasal intermittent positive airway pressure ventilation (nIPPV), bi-level positive airway pressure (BiPAP), nasal high-frequency oscillatory ventilation (nHFOV), and nasally applied, non-invasive neurally adjusted ventilatory assist (NIV-NAVA) modes, with particular focus on their use in preterm infants. SUMMARY This is a narrative review with reference to published guidelines by European Consensus Guidelines on the Management of Respiratory Distress Syndrome: 2022 Update. nCPAP is currently the most commonly used primary and secondary NIV modality for premature infants. However, there is increasing evidence on the superiority of nIPPV over nCPAP. No beneficial effect was found for BiPAP over nCPAP. For the use of nHFT, nHFOV, and NIV-NAVA, more studies are needed to establish their place in neonatal respiratory care. KEY MESSAGES The superiority of nIPPV over nCPAP needs to be confirmed by contemporaneous trials comparing nCPAP to nIPPV at comparable mean airway pressures. Future trials should study NIV modalities in preterm infants with comparable respiratory pathology and indications, at comparable pressure settings and with different modes of synchronisation. Importantly, future trials should not exclude infants of the smallest gestational ages.

Abstract
AIM To describe the effect of resuscitation with bubble CPAP (bCPAP) versus T-piece device at birth on early clinical parameters and hospital outcomes in infants born <32 weeks gestation. METHODS This is a single-centre pre- and post-implementation study comparing outcomes in two epochs. In epoch 1 (1 July 2013-31 December 2014), infants were managed with non-humidified gas using Neopuff® T-piece devices to support breathing after birth. In epoch 2 (1 March 2020-31 December 2021), routine application of bCPAP with humidified gas was introduced at birth. RESULTS Three hundred fifty-seven patients were included (176 epoch 1, 181 epoch 2). The mean gestational age was 28 ± 2 weeks. The demographics of the two epochs were comparable. There were significant improvements in outcomes of infants in epoch 2 with less infants intubated at delivery (16% vs. 4%, P ≤ 0.001), improved 5 min Apgar (7 vs. 8, P ≤ 0.001), reduced need for ventilation (21% vs. 8.8%, P ≤ 0.001), duration of ventilation in the first 72 h (9.6 vs. 4.6 h) and mortality (10.8% vs. 1.7%, P ≤ 0.001). There was, increased incidence of chronic lung disease (30% vs. 55%, P = 0.02) but no increase in infants discharged on oxygen (3.8% vs. 5%, P = 0.25). Similar findings were observed in a subgroup of infants born <25 weeks' gestation with no increase in the incidence of CLD. CONCLUSION Introducing application of bCPAP from the first breaths in infants <32 weeks' gestation was associated with better short-term outcomes and mortality, albeit with increased incidence of CLD. The subgroup of infants born <25 weeks' gestation showed similar change in outcomes, with no increase in CLD.

Abstract
OBJECTIVE Positive pressure ventilation (PPV) is crucial to the resuscitation of newborns. Although neonates often require PPV at birth, the optimal interface has not been determined. Both binasal prongs and face masks were deemed acceptable by the International Liaison Committee on Resuscitation in 2010 and have been utilized at our center since 2016; however, the choice is by provider preference. Previous studies have suggested that binasal prongs may be more effective than face masks at avoiding intubation in the delivery room. The objective of this study is to compare intubation rates of binasal prongs versus face masks for delivery room resuscitation of neonates born < 30 weeks' gestation. STUDY DESIGN This retrospective study compares delivery room intubation rates by interface for neonates < 30 weeks' gestation born between August 2016 and April 2021 at our level IV neonatal intensive care unit. Exclusion criteria included diagnosis of congenital diaphragmatic hernia, no PPV required, or no resuscitation attempted. Data collected included interface device, demographics, maternal data, delivery room data, admission data, and discharge outcomes. The three interface groups (binasal prongs, face mask, face mask, and binasal prongs) were compared utilizing chi-square, analysis of variance with post hoc analysis, and logistic regression. RESULTS Mean gestational ages and birth weights for the groups were 27.6 weeks and 1,126 g, 25.7 weeks and 839 g, and 27.1 weeks and 1,028 g, respectively. Neonates resuscitated with face masks were 9.9 times more likely to be intubated in the delivery room and 10.8 times more likely to be intubated at 6 hours of life compared with those resuscitated with binasal prongs after logistic regression analysis. CONCLUSION The findings in our study support delivery room resuscitation with binasal prongs as a useful method in reducing the need for intubation both in the delivery room and at 6 hours of life. Further prospective studies are warranted. KEY POINTS · The International Liaison Committee on Resuscitation recommends multiple interface options for neonatal resuscitation.. · Vermont Oxford Network endorses nasal interface for premature infants.. · Binasal prongs are associated with lower intubation rates..

Abstract
Our objective was to conduct a systematic review and meta-analysis evaluating the effects of administering positive end-expiratory pressure (PEEP) during neonatal resuscitation at birth. Medline, Web of Science, Scopus, Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov databases were systematically searched from inception to 15 December 2020. Randomized controlled trials and cohort studies were held eligible. Studies were included if they compared the administration of PEEP using either a T-piece resuscitator or a self-inflating bag with a PEEP valve versus resuscitation via a self-inflating bag without a PEEP valve. Data were extracted by two reviewers independently. The credibility of evidence was appraised with the Grading of Recommendations, Assessment, Development, and Evaluations approach. Random-effects models were fitted to provide pooled estimates of risk ratio (RR) and 95% confidence intervals (CIs). Overall, 10 studies were included, comprising 4,268 neonates. This included five randomized controlled trials, one quasi-randomized trial, and four cohort studies. The administration of PEEP was associated with significantly lower rates of mortality till discharge (odds ratio [OR]: 0.60, 95% CI: 0.49-0.74, moderate quality of evidence). The association was significant in preterm (OR: 0.57, 95% CI: 0.46-0.69) but not in term (OR: 1.03, 95% CI: 0.52-2.02) neonates. Low-to-moderate quality evidence suggests that providing PEEP during neonatal resuscitation is associated with lower rates of mortality in preterm neonates. Evidence regarding term neonates is limited and inconclusive. Future research is needed to determine the optimal device and shed more light on the long-term effects of PEEP administration during neonatal resuscitation. This study is registered with PROSPERO with registration number: CRD42020219956. KEY POINTS: · PEEP administration during neonatal resuscitation in the delivery room reduces mortality in preterm.. · Evidence regarding term neonates is limited and inconclusive.. · Future research is needed to determine the optimal device..

Abstract
BACKGROUND The rPAP respiratory support system, used for delivery room stabilisation with nasal prongs, has been shown to reduce the need for intubation in extremely preterm infants. A simplified version of the system has been developed. The purpose of this study was to determine the feasibility of providing uninterrupted respiratory support with the simplified rPAP from birth up to 4 hours of life and to assess ease of use for skin-to skin stabilisation. METHODS This was a non-randomised feasibility study conducted at Karolinska University Hospital, Sweden. Respiratory support with continuous positive airway pressure (CPAP) and positive pressure ventilation if needed was given with the simplified rPAP using heated humidified gases. Respiratory support was provided in the delivery room, during transportation and in the neonatal unit, for a maximum of 4 hours. RESULTS 32 preterm infants with a mean (SD) gestational age of 33.4 weeks (±1.2) were included. Of 17 infants born vaginally, 13 were stabilised skin-to-skin. The remaining infants were stabilised on a resuscitation table. All infants received CPAP and nine received positive pressure ventilation. 31 infants received continued support during transport and after arrival in the neonatal unit. Minor interruptions in CPAP support occurred in all infants. The study did not reveal problems with usability of the system. CONCLUSION It is feasible to stabilise preterm infants with the simplified respiratory support system both skin-to-skin and on a resuscitation table, and to provide continued respiratory support with the same system during transportation and in the neonatal unit.

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
Importance Preterm newborns at risk of respiratory distress syndrome are supported with continuous positive airway pressure (CPAP). Many newborns worsen despite CPAP and are intubated for surfactant administration, an effective therapy for treatment of respiratory distress syndrome. Endotracheal intubation is associated with adverse effects. Pharyngeal administration of surfactant to preterm animals and humans has been reported as an alternative. Objective To assess whether giving prophylactic oropharyngeal surfactant to preterm newborns at birth would reduce the rate of intubation for respiratory failure. Design, Setting, and Participants This unblinded, parallel-group randomized clinical trial (Prophylactic Oropharyngeal Surfactant for Preterm Infants [POPART]) was conducted from December 17, 2017, to September 11, 2020, at 9 tertiary neonatal intensive care units in 6 European countries. Newborns born before 29 weeks of gestation without severe congenital anomalies, for whom intensive care was planned, were eligible for inclusion. The data were analyzed from July 27, 2022, to June 20, 2023. Intervention Newborns were randomly assigned to receive oropharyngeal surfactant at birth in addition to CPAP or CPAP alone. Randomization was stratified by center and gestational age (GA). Main Outcomes and Measures The primary outcome was intubation in the delivery room for bradycardia and/or apnea or in the neonatal intensive care unit for prespecified respiratory failure criteria within 120 hours of birth. Caregivers were not masked to group assignment. Results Among 251 participants (mean [SD] GA, 26 [1.5] weeks) who were well matched at study entry, 126 (69 [54.8%] male) with a mean (SD) birth weight of 858 (261) grams were assigned to the oropharyngeal surfactant group, and 125 (63 [50.4%] male) with a mean (SD) birth weight of 829 (253) grams were assigned to the control group. The proportion of newborns intubated within 120 hours was not different between the groups (80 [63.5%) in the oropharyngeal surfactant group and 81 [64.8%] in the control group; relative risk, 0.98 [95% CI, 0.81-1.18]). More newborns assigned to the oropharyngeal surfactant group were diagnosed with and treated for pneumothorax (21 [16.6%] vs 8 [6.4%]; P = .04). Conclusions and Relevance This randomized clinical trial found that administration of prophylactic oropharyngeal surfactant to newborns born before 29 weeks' GA did not reduce the rate of intubation in the first 120 hours of life. These findings suggest that administration of surfactant into the oropharynx immediately after birth in addition to CPAP should not be routinely used. Trial Registration EudraCT: 2016-004198-41.

Abstract
RATIONALE Lung recruitment and continuous distending pressure (CDP) titration are critical for assuring the efficacy of high-frequency ventilation (HFOV) in preterm infants. The limitation of oxygenation (peripheral oxygen saturation, SpO2) in optimizing CDP calls for evaluating other non-invasive bedside measurements. Respiratory reactance (Xrs) at 10 Hz measured by oscillometry reflects lung volume recruitment and tissue strain. In particular, lung volume recruitment and decreased tissue strain result in increased Xrs values. OBJECTIVES In extremely preterm infants treated with HFOV as first intention, we aimed to measure the relationship between CDP and Xrs during SpO2-driven CDP optimization. METHODS In this prospective observational study, extremely preterm infants born before 28 weeks of gestation undergoing SpO2-guided lung recruitment maneuvers were included in the study. SpO2 and Xrs were recorded at each CDP step. The optimal CDP identified by oxygenation (CDPOpt_SpO2) was compared to the CDP providing maximal Xrs on the deflation limb of the recruitment maneuver (CDPXrs). RESULTS We studied 40 infants (gestational age at birth = 22+ 6-27+ 5 wk; postnatal age = 1-23 days). Measurements were well tolerated and provided reliable results in 96% of cases. On average, Xrs decreased during the inflation limb and increased during the deflation limb. Xrs changes were heterogeneous among the infants for the amount of decrease with increasing CDP, the decrease at the lowest CDP of the deflation limb, and the hysteresis of the Xrs vs. CDP curve. In all but five infants, the hysteresis of the Xrs vs. CDP curve suggested effective lung recruitment. CDPOpt_SpO2 and CDPXrs were highly correlated (ρ = 0.71, p < 0.001) and not statistically different (median difference [range] = -1 [-3; 9] cmH2O). However, CDPXrs were equal to CDPOpt_SpO2 in only 6 infants, greater than CDPOpt_SpO2 in 10, and lower in 24 infants. CONCLUSIONS The Xrs changes described provide complementary information to oxygenation. Further investigation is warranted to refine recruitment maneuvers and CPD settings in preterm infants.

Pediatr Res 2023; 94:1929-1934. [PMID: 37460710 DOI: 10.1038/s41390-023-02715-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 06/01/2023] [Accepted: 06/14/2023] [Indexed: 11/24/2023]
Abstract
BACKGROUND The importance of neonatal resuscitator resistance is currently unknown. In this study we investigated peak flows and pressure stability resulting from differences in imposed resistance during positive pressure ventilation(PPV) and simulated spontaneous breathing (SSB) between the r-PAP, low-resistance resuscitator, and Neopuff™, high-resistance resuscitator. METHODS In a bench test, 20 inflations during PPV and 20 breaths during SSB were analysed on breath-by-breath basis to determine peak flow and pressure stability using the Neopuff™ with bias gas flow of 8, 12 or 15 L/min and the r-PAP with total gas flow of 15 L/min. RESULTS Imposed resistance of the Neopuff™ was significantly reduced when the bias gas flow was increased from 8 to 15 L/min, which resulted in higher peak flows during PPV and SSB. Peak flows in the r-PAP were, however, significantly higher and fluctuations in CPAP during SSB were significantly smaller in the r-PAP compared to the Neopuff™ for all bias gas flow levels. During PPV, a pressure overshoot of 3.2 cmH2O was observed in the r-PAP. CONCLUSIONS The r-PAP seemed to have a lower resistance than the Neopuff™ even when bias gas flows were increased. This resulted in more stable CPAP pressures with higher peak flows when using the r-PAP. IMPACT The traditional T-piece system (Neopuff™) has a higher imposed resistance compared to a new neonatal resuscitator (r-PAP). This study shows that reducing imposed resistance leads to smaller CPAP fluctuations and higher inspiratory and expiratory peak flows. High peak flows might negatively affect lung function and/or cause lung injury in preterm infants at birth. This study will form the rationale for further studies investigating these effects. A possible compromise might be to use the traditional T-piece system with a higher bias gas flow (12 L/min), thereby reducing the imposed resistance and generating more stable PEEP/CPAP pressures, while limiting potentially harmful peak flows.

Abstract
BACKGROUND The Neonatal Task Force of the International Liaison Committee on Resuscitation (ILCOR) makes practice recommendations for the care of newborn infants in the delivery room (DR). ILCOR recommends that all infants who are gasping, apnoeic, or bradycardic (heart rate < 100 per minute) should be given positive pressure ventilation (PPV) with a manual ventilation device (T-piece, self-inflating bag, or flow-inflating bag) via an interface. The most commonly used interface is a face mask that encircles the infant's nose and mouth. However, gas leak and airway obstruction are common during face mask PPV. Nasal interfaces (single and binasal prongs (long or short), or nasal masks) and laryngeal mask airways (LMAs) may also be used to deliver PPV to newborns in the DR, and may be more effective than face masks. OBJECTIVES To determine whether newborn infants receiving PPV in the delivery room with a nasal interface compared to a face mask, laryngeal mask airway (LMA), or another type of nasal interface have reduced mortality and morbidity. To assess whether safety and efficacy of the nasal interface differs according to gestational age or ventilation device. SEARCH METHODS Searches were conducted in September 2022 in CENTRAL, MEDLINE, Embase, Epistemonikos, and two trial registries. We searched conference abstracts and checked the reference lists of included trials and related systematic reviews identified through the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCT's that compared the use of nasal interfaces to other interfaces (face masks, LMAs, or one nasal interface to another) to deliver PPV to newborn infants in the DR. DATA COLLECTION AND ANALYSIS Each review author independently evaluated the search results against the selection criteria, screened retrieved records, extracted data, and appraised the risk of bias. If they were study authors, they did not participate in the selection, risk of bias assessment, or data extraction related to the study. In such instances, the study was independently assessed by other review authors. We contacted trial investigators to obtain additional information. We completed data analysis according to the standards of Cochrane Neonatal, using risk ratio (RR) and 95% confidence Intervals (CI) to measure the effect of the different interfaces. We used fixed-effect models and the GRADE approach to assess the certainty of the evidence. MAIN RESULTS We included five trials, in which 1406 infants participated. They were conducted in 13 neonatal centres across Europe and Australia. Each of these trials compared a nasal interface to a face mask for the delivery of respiratory support to newborn infants in the DR. Potential sources of bias were a lack of blinding to treatment allocation of the caregivers and investigators in all trials. The evidence suggests that resuscitation with a nasal interface in the DR, compared with a face mask, may have little to no effect on reducing death before discharge (typical risk ratio (RR) 0.72, 95% CI 0.47 to 1.13; 3 studies, 1124 infants; low-certainty evidence). Resuscitation with a nasal interface may reduce the rate of intubation in the DR, but the evidence is very uncertain (RR 0.68, 95% CI 0.54 to 0.85; 5 studies, 1406 infants; very low-certainty evidence). The evidence is very uncertain for the rate of intubation within 24 hours of birth (RR 0.97, 95% CI 0.85 to 1.09; 3 studies, 749 infants; very low-certainty evidence), endotracheal intubation outside the DR during hospitalisation (RR 1.15, 95% CI 0.93 to 1.42; 1 study, 144 infants; very low-certainty evidence) and cranial ultrasound abnormalities (intraventricular haemorrhage (IVH) grade ≥ 3, or periventricular leukomalacia; RR 0.94, 95% CI 0.55 to 1.61; 3 studies, 749 infants; very low-certainty evidence). Resuscitation with a nasal interface in the DR, compared with a face mask, may have little to no effect on the incidence of air leaks (RR 1.09, 95% CI 0.85 to 1.09; 2 studies, 507 infants; low-certainty evidence), or the need for supplemental oxygen at 36 weeks' corrected gestational age (RR 1.06, 95% CI 0.8 to 1.40; 2 studies, 507 infants; low-certainty evidence). We identified one ongoing study, which compares a nasal mask to a face mask to deliver PPV to infants in the DR. We did not identify any completed trials that compared nasal interfaces to LMAs or one nasal interface to another. AUTHORS' CONCLUSIONS Nasal interfaces were found to offer comparable efficacy to face masks (low- to very low-certainty evidence), supporting resuscitation guidelines that state that nasal interfaces are a comparable alternative to face masks for providing respiratory support in the DR. Resuscitation with a nasal interface may reduce the rate of intubation in the DR when compared with a face mask. However, the evidence is very uncertain. This uncertainty is attributed to the use of a new ventilation system in the nasal interface group in two of the five trials. As such, it is not possible to differentiate separate, specific effects related to the ventilation device or to the interface in these studies.

Abstract
Opportunities to learn and maintain competence in neonatal intubation have decreased. As many clinicians providing care to the newborn infant are not skilled in intubation, alternative strategies are critical. Most preterm infants breathe spontaneously, and require stabilisation rather than resuscitation at birth. Use of tactile stimulation, deferred cord clamping, and avoidance of hypoxia can help optimise breathing for these infants. Nasal devices appear a promising alternative to the face mask for early provision of respiratory support. In term and near-term infants, supraglottic airways may be the most effective initial approach to resuscitation. Use of supraglottic airways during resuscitation can be taught to a range of providers, and may reduce need for intubation. While face mask ventilation is an important skill, it is challenging to perform effectively. Identification of the best approach to training the use of these devices during neonatal resuscitation remains an important priority.

Abstract
AIM To study if stabilisation using a new respiratory support system with nasal prongs compared to T-piece with a face mask is associated with less need for mechanical ventilation and bronchopulmonary dysplasia. METHODS A single-centre follow-up study of neonates born <28 weeks gestation at Karolinska University Hospital, Stockholm included in the multicentre Comparison of Respiratory Support after Delivery (CORSAD) trial and randomised to initial respiratory support with the new system versus T-piece. Data on respiratory support, neonatal morbidities and mortality were collected up to 36 weeks post-menstrual age. RESULTS Ninety-four infants, 51 female, with a median (range) gestational age of 25 + 2 (23 + 0, 27 + 6) weeks and days, were included. Significantly fewer infants in the new system group received mechanical ventilation during the first 72 h, 24 (52.2%) compared with 35 (72.9%) (p = 0.034) and during the first 7 days, 29 (63.0%) compared with 39 (81.3%) (p = 0.045) in the T-piece group. At 36 weeks post-menstrual age, 13 (28.3%) in the new system and 13 (27.1%) in the T-piece group were diagnosed with bronchopulmonary dysplasia. CONCLUSION Stabilisation with the new system was associated with less need for mechanical ventilation during the first week of life. No significant difference was seen in the outcome of bronchopulmonary dysplasia.

Abstract
Respiratory distress syndrome (RDS) care pathways evolve slowly as new evidence emerges. We report the sixth version of "European Guidelines for the Management of RDS" by a panel of experienced European neonatologists and an expert perinatal obstetrician based on available literature up to end of 2022. Optimising outcome for babies with RDS includes prediction of risk of preterm delivery, appropriate maternal transfer to a perinatal centre, and appropriate and timely use of antenatal steroids. Evidence-based lung-protective management includes initiation of non-invasive respiratory support from birth, judicious use of oxygen, early surfactant administration, caffeine therapy, and avoidance of intubation and mechanical ventilation where possible. Methods of ongoing non-invasive respiratory support have been further refined and may help reduce chronic lung disease. As technology for delivering mechanical ventilation improves, the risk of causing lung injury should decrease, although minimising time spent on mechanical ventilation by targeted use of postnatal corticosteroids remains essential. The general care of infants with RDS is also reviewed, including emphasis on appropriate cardiovascular support and judicious use of antibiotics as being important determinants of best outcome. We would like to dedicate this guideline to the memory of Professor Henry Halliday who died on November 12, 2022.These updated guidelines contain evidence from recent Cochrane reviews and medical literature since 2019. Strength of evidence supporting recommendations has been evaluated using the GRADE system. There are changes to some of the previous recommendations as well as some changes to the strength of evidence supporting recommendations that have not changed. This guideline has been endorsed by the European Society for Paediatric Research (ESPR) and the Union of European Neonatal and Perinatal Societies (UENPS).

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.

Abstract
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.

Abstract
BACKGROUND Providing appropriate care at birth remains a crucial strategy for reducing neonatal mortality and morbidity. We aimed to evaluate the consistency of practice and the adherence to the international guidelines on neonatal resuscitation in level-I and level-II Italian birth hospitals. METHODS This was a cross-sectional electronic survey. A 91-item questionnaire focusing on current delivery room practices in neonatal resuscitation was sent to the directors of 418 Italian neonatal facilities. RESULTS The response rate was 61.7% (258/418), comprising 95.6% (110/115) from level-II and 49.0% (148/303) from level-I centres. In 2018, approximately 300,000 births occurred at the participating hospitals, with a median of 1664 births/centre in level-II and 737 births/centre in level-I hospitals. Participating level-II hospitals provided nasal-CPAP and/or high-flow nasal cannulae (100%), mechanical ventilation (99.1%), HFOV (71.0%), inhaled nitric oxide (80.0%), therapeutic hypothermia (76.4%), and extracorporeal membrane oxygenation ECMO (8.2%). Nasal-CPAP and/or high-flow nasal cannulae and mechanical ventilation were available in 77.7 and 21.6% of the level-I centres, respectively. Multidisciplinary antenatal counselling was routinely offered to parents at 90.0% (90) of level-II hospitals, and 57.4% (85) of level-I hospitals (p < 0.001). Laryngeal masks were available in more than 90% of participating hospitals while an end-tidal CO2 detector was available in only 20%. Significant differences between level-II and level-I centres were found in the composition of resuscitation teams for high-risk deliveries, team briefings before resuscitation, providers qualified with full resuscitation skills, self-confidence, and use of sodium bicarbonate. CONCLUSIONS This survey provides insight into neonatal resuscitation practices in a large sample of Italian hospitals. Overall, adherence to international guidelines on neonatal resuscitation was high, but differences in practice between the participating centres and the guidelines exist. Clinicians and stakeholders should consider this information when allocating resources and planning perinatal programs in Italy.

Abstract
BACKGROUND AND OBJECTIVES The Brazilian Neonatal Resuscitation Program releases guidelines based on local interpretation of international consensus on science and treatment recommendations. We aimed to analyze whether guidelines for preterm newborns were applied to practice in the 20 Brazilian Network on Neonatal Research centers of this middle-income country. METHODS Prospectively collected data from 2014 to 2020 were analyzed for 8514 infants born at 230/7 to 316/7 weeks' gestation. The frequency of procedures was evaluated by gestational age (GA) category, including use of a thermal care bundle, positive pressure ventilation (PPV), PPV with a T-piece resuscitator, maximum fraction of inspired oxygen (Fio2) concentration during PPV, tracheal intubation, chest compressions and medications, and use of continuous positive airway pressure in the delivery room. Logistic regression, adjusted by center and year, was used to estimate the probability of receiving recommended treatment. RESULTS For 3644 infants 23 to 27 weeks' GA and 4870 infants 28 to 31 weeks' GA, respectively, the probability of receiving care consistent with guidelines per year increased, including thermal care (odds ratio [OR], 1.52 [95% confidence interval (CI) 1.44-1.61] and 1.45 [1.38-1.52]) and PPV with a T-piece (OR, 1.45 [95% CI 1.37-1.55] and 1.41 [1.32-1.51]). The probability of receiving PPV with Fio2 1.00 decreased equally in both GA groups (OR, 0.89; 95% CI, 0.86-0.93). CONCLUSIONS Between 2014 and 2020, the resuscitation guidelines for newborns <32 weeks' GA on thermal care, PPV with a T-piece resuscitator, and decreased use of Fio2 1.00 were translated into clinical practice.

Abstract
Lung immaturity and acute respiratory failure are the major problems in the care of extremely preterm infants. Most infants with gestational age (GA) 22-24 weeks will need mechanical ventilation and many will depend on some type of respiratory support, invasive and non-invasive for extended periods. There is ongoing gap in knowledge regarding optimal respiratory support and applying strategies that are effective in more mature populations is not easy or even suitable because lung maturation differs in smaller infants. Better strategies on how to avoid lung damage and to promote growth and development of the immature lung are warranted since increased survival is accompanied by increasing rates of bronchopulmonary dysplasia and concerns over long-standing reductions in lung function. This review focuses on some aspects of respiratory care of infants born at 22-24 weeks of GA.

Abstract
OBJECTIVE The resistance created by the PEEP-valve of a T-piece resuscitator is bias gas flow dependent and might affect breathing in preterm infants. In this study we investigated the effect of a higher bias gas flow on the imposed inspiratory and expiratory T-piece resistance and expiratory breaking manoeuvres (EBM) in preterm infants during spontaneous breathing on CPAP at birth. METHODS In a retrospective pre-post implementation study of preterm infants <32 weeks gestation, who were stabilised with a T-piece resuscitator, a bias gas flow of 12 L/min was compared to 8 L/min. All spontaneous breaths on CPAP within the first 10 min of starting respiratory support were analysed on a breath-by-breath basis to determine the breathing pattern of each breath and to calculate the imposed inspiratory and expiratory T-piece resistance (Ri, Re), flow rates and tidal volume. RESULTS In total, 54 infants were included (bias gas flow 12 L/min: n = 27, 8 L/min: n = 27) with a median GA of 29+6 (28+4-30+3) and 28+5 (25+6-30+3), respectively (p = 0.182). Ri and Re were significantly lower in the 12 L/min compared to 8 L/min bias flow group [Ri: 29.6 (26.1-33.6) vs. 46.4 (43.0-54.1) cm H2O/L/s, p < 0.001; Re: 32.0 (30.0-35.1) vs. 48.0 (46.3-53.9) cm H2O/L/s, p < 0.001], while the incidence of EBM [77% (53-88) vs. 77% (58-90), p = 0.586] was similar. CONCLUSION During stabilisation of preterm infants at birth with a T-piece resuscitator, the use of a higher bias gas flow reduced both the imposed inspiratory and expiratory T-piece resistance for the infant, but this did not influence the incidence of EBMs.
