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
OBJECTIVE Neonatal endotracheal intubation is a lifesaving but technically difficult procedure, particularly for inexperienced operators. This secondary analysis in a subgroup of inexperienced operators of the Stabilization with nasal High flow during Intubation of NEonates randomised trial aimed to identify the factors associated with successful intubation on the first attempt without physiological stability of the infant. METHODS In this secondary analysis, demographic factors were compared between infants intubated by inexperienced operators and those intubated by experienced operators. Following this, for inexperienced operators only, predictors of successful intubation without physiological instability were analysed. RESULTS A total of 251 intubations in 202 infants were included in the primary intention-to-treat analysis of the main trial. Inexperienced operators were more likely to perform intubations in larger and more mature infants in the neonatal intensive care unit where premedications were used. When intubations were performed by inexperienced operators, the use of nasal high flow therapy (nHF) and a higher starting fraction of inspired oxygen were associated with a higher rate of safe, successful intubation on the first attempt. There was a weaker association between premedication use and first attempt success. CONCLUSIONS In inexperienced operators, this secondary, non-randomised analysis suggests that the use of nHF and premedications, and matching the operator to the infant and setting, may be important to optimise neonatal intubation success.

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
OBJECTIVE To describe initial experience with use of the Glidescope Go videolaryngoscope by an Australian neonatal pre-hospital and retrieval service. METHODS We conducted a 31-month retrospective review of an airway registry for neonates intubated by MedSTAR Kids clinicians. RESULTS Twenty-two patients were intubated using the Glidescope Go, compared with 50 using direct laryngoscopy. First-pass success was 17/22 (77.3%) with the Glidescope Go and 38/50 (76%) with direct laryngoscopy. Complications occurred in 7/22 (32%) and 8/50 (16%), respectively. CONCLUSIONS On initial review of this practice change, videolaryngoscopy allows neonatal tracheal intubation with a comparable success rate to direct laryngoscopy in a pre-hospital and retrieval setting.

Abstract
BACKGROUND Repeated attempts at endotracheal intubation are associated with increased adverse events in neonates. When clinicians view the airway directly with a laryngoscope, fewer than half of first attempts are successful. The use of a video laryngoscope, which has a camera at the tip of the blade that displays a view of the airway on a screen, has been associated with a greater percentage of successful intubations on the first attempt than the use of direct laryngoscopy in adults and children. The effect of video laryngoscopy among neonates is uncertain. METHODS In this single-center trial, we randomly assigned neonates of any gestational age who were undergoing intubation in the delivery room or neonatal intensive care unit (NICU) to the video-laryngoscopy group or the direct-laryngoscopy group. Randomization was stratified according to gestational age (<32 weeks or ≥32 weeks). The primary outcome was successful intubation on the first attempt, as determined by exhaled carbon dioxide detection. RESULTS Data were analyzed for 214 of the 226 neonates who were enrolled in the trial, 63 (29%) of whom were intubated in the delivery room and 151 (71%) in the NICU. Successful intubation on the first attempt occurred in 79 of the 107 patients (74%; 95% confidence interval [CI], 66 to 82) in the video-laryngoscopy group and in 48 of the 107 patients (45%; 95% CI, 35 to 54) in the direct-laryngoscopy group (P<0.001). The median number of attempts to achieve successful intubation was 1 (95% CI, 1 to 1) in the video-laryngoscopy group and 2 (95% CI, 1 to 2) in the direct-laryngoscopy group. The median lowest oxygen saturation during intubation was 74% (95% CI, 65 to 78) in the video-laryngoscopy group and 68% (95% CI, 62 to 74) in the direct-laryngoscopy group; the lowest heart rate was 153 beats per minute (95% CI, 148 to 158) and 148 (95% CI, 140 to 156), respectively. CONCLUSIONS Among neonates undergoing urgent endotracheal intubation, video laryngoscopy resulted in a greater number of successful intubations on the first attempt than direct laryngoscopy.

Abstract
The survival and health of preterm and critically ill infants have markedly improved over the past 50 years, supported by well-conducted neonatal research. However, newborn research is difficult to undertake for many reasons, and obtaining informed consent for research in this population presents several unique ethical and logistical challenges. In this article, we explore methods to facilitate the consent process, including the role of checklists to support meaningful informed consent for neonatal clinical trials. CONCLUSION: The authors provide practical guidance on the design and implementation of an effective consent checklist tailored for use in neonatal clinical research.

Abstract
BACKGROUND Over 95% of infants less than 32 weeks gestational age-very preterm infants (VPTI)-require cardiorespiratory support at birth. Clinical condition at birth is assessed by the Apgar score, but the precision and accuracy of activity and grimace has not been evaluated. We hypothesised activity and grimace could predict the level of cardiorespiratory support required for stabilisation. METHODS Two hundred twenty-nine videos of VPTI resuscitations at Monash Children's Hospital and The Royal Women's Hospital, Melbourne were evaluated, with 78 videos eligible for assessment. Activity and grimace were scored (0, 1, or 2) by seven consultant neonatologists, with inter-rater reliability assessed. Activity and grimace were correlated with the maximum level of cardiorespiratory support required for stabilisation. RESULTS Kendall's Coefficient of Concordance (W) showed strong interobserver agreement for activity (W = 0.644, p < 0.001) and grimace (W = 0.722, p < 0.001). Neither activity nor grimace independently predicted the level of cardiorespiratory support required. Combining activity and grimace showed non-vigorous infants (combined score <2) received more cardiorespiratory support than vigorous (combined score ≥ 2). CONCLUSION Scoring of activity and grimace was consistent between clinicians. Independently, activity and grimace did not correlate with perinatal stabilisation. Combined scoring showed non-vigorous infants had greater resuscitation requirements. IMPACT Our study evaluates the precision and accuracy of activity and grimace to predict perinatal stability, which has not been validated in infants <32 weeks gestational age. We found strong score agreement between assessors, indicating video review is a practical and precise method for grading of activity and grimace. Combined scoring to allow a dichotomous evaluation of infants as non-vigorous or vigorous showed the former group required greater cardiorespiratory support at birth.

High-flow nasal oxygenation versus face mask oxygenation for preoxygenation in patients undergoing double-lumen endobronchial intubation: protocol of a randomised controlled trial.

Abstract
INTRODUCTION With the growing emphasis on swift recovery, minimally invasive thoracic surgery has advanced significantly. Video-assisted thoracoscopic surgery (VATS) has seen rapid development, and the double-lumen tube (DLT) remains the most dependable method for tracheal intubation in VATS. However, hypoxaemia during DLT intubation poses a threat to the perioperative safety of thoracic surgery patients. Recently, transnasal high-flow nasal oxygen (HFNO) has shown promise in anaesthesia, particularly in handling short-duration hypoxic airway emergencies. Yet, its application in the perioperative period for patients undergoing pulmonary surgery with compromised cardiopulmonary function lacks evidence, and there are limited reliable clinical data. METHODS AND ANALYSIS A prospective, randomised, controlled, single-blind design will be employed in this study. 112 patients aged 18-60 years undergoing elective VATS-assisted pulmonary surgery will be enrolled and randomly divided into two groups: the nasal high-flow oxygen group (H group) and the traditional mask transnasal oxygen group (M group) in a 1:1 ratio. HFNO will be used during DLT intubation for the prevention of asphyxia in group H, while conventional intubation procedures will be followed by group M. Comparison will be made between the two groups in terms of minimum oxygen saturation during intubation, hypoxaemia incidence during intubation, perioperative complications and postoperative hospital days. ETHICS AND DISSEMINATION Approval for this study has been granted by the local ethics committee at Shenzhen Second People's Hospital. The trial results will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER NCT05666908.

Apnoeic oxygenation during paediatric tracheal intubation: a systematic review and meta-analysis. Br J Anaesth 2024; 132:392-406. [PMID: 38030551 DOI: 10.1016/j.bja.2023.10.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 10/03/2023] [Accepted: 10/24/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Supplemental oxygen administration by apnoeic oxygenation during laryngoscopy for tracheal intubation is intended to prolong safe apnoea time, reduce the risk of hypoxaemia, and increase the success rate of first-attempt tracheal intubation under general anaesthesia. This systematic review examined the efficacy and effectiveness of apnoeic oxygenation during tracheal intubation in children. METHODS This systematic review and meta-analysis included randomised controlled trials and non-randomised studies in paediatric patients requiring tracheal intubation, evaluating apnoeic oxygenation by any method compared with patients without apnoeic oxygenation. Searched databases were MEDLINE, Embase, Cochrane Library, CINAHL, ClinicalTrials.gov, International Clinical Trials Registry Platform (ICTRP), Scopus, and Web of Science from inception to March 22, 2023. Data extraction and risk of bias assessment followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) recommendation. RESULTS After initial selection of 40 708 articles, 15 studies summarising 9802 children were included (10 randomised controlled trials, four pre-post studies, one prospective observational study) published between 1988 and 2023. Eight randomised controlled trials were included for meta-analysis (n=1070 children; 803 from operating theatres, 267 from neonatal intensive care units). Apnoeic oxygenation increased intubation first-pass success with no physiological instability (risk ratio [RR] 1.27, 95% confidence interval [CI] 1.03-1.57, P=0.04, I2=0), higher oxygen saturation during intubation (mean difference 3.6%, 95% CI 0.8-6.5%, P=0.02, I2=63%), and decreased incidence of hypoxaemia (RR 0.24, 95% CI 0.17-0.33, P<0.01, I2=51%) compared with no supplementary oxygen administration. CONCLUSION This systematic review with meta-analysis confirms that apnoeic oxygenation during tracheal intubation of children significantly increases first-pass intubation success rate. Furthermore, apnoeic oxygenation enables stable physiological conditions by maintaining oxygen saturation within the normal range. CLINICAL TRIAL REGISTRATION Protocol registered prospectively on PROSPERO (registration number: CRD42022369000) on December 2, 2022.

Abstract
Airway management is required during general anaesthesia and is essential for life-threatening conditions such as cardiopulmonary resuscitation. Evidence from recent trials indicates a high incidence of critical events during airway management, especially in neonates or infants. It is important to define the optimal techniques and strategies for airway management in these groups. In this joint European Society of Anaesthesiology and Intensive Care (ESAIC) and British Journal of Anaesthesia (BJA) guideline on airway management in neonates and infants, we present aggregated and evidence-based recommendations to assist clinicians in providing safe and effective medical care. We identified seven main areas of interest for airway management: i) preoperative assessment and preparation; ii) medications; iii) techniques and algorithms; iv) identification and treatment of difficult airways; v) confirmation of tracheal intubation; vi) tracheal extubation, and vii) human factors. Based on these areas, Population, Intervention, Comparison, Outcomes (PICO) questions were derived that guided a structured literature search. GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology was used to formulate the recommendations based on those studies included with consideration of their methodological quality (strong '1' or weak '2' recommendation with high 'A', medium 'B' or low 'C' quality of evidence). In summary, we recommend: 1. Use medical history and physical examination to predict difficult airway management (1C). 2. Ensure adequate level of sedation or general anaesthesia during airway management (1B). 3. Administer neuromuscular blocker before tracheal intubation when spontaneous breathing is not necessary (1C). 4. Use a videolaryngoscope with an age-adapted standard blade as first choice for tracheal intubation (1B). 5. Apply apnoeic oxygenation during tracheal intubation in neonates (1B). 6. Consider a supraglottic airway for rescue oxygenation and ventilation when tracheal intubation fails (1B). 7. Limit the number of tracheal intubation attempts (1C). 8. Use a stylet to reinforce and preshape tracheal tubes when hyperangulated videolaryngoscope blades are used and when the larynx is anatomically anterior (1C). 9. Verify intubation is successful with clinical assessment and end-tidal CO2 waveform (1C). 10. Apply high-flow nasal oxygenation, continuous positive airway pressure or nasal intermittent positive pressure ventilation for postextubation respiratory support, when appropriate (1B).

Abstract
Neonatal airway management comes with exclusive anatomical, physiological, and environmental complexities, and probably higher incidences of accidents and complications. No dedicated airway management guidelines were available until the recently published first joint guideline released by a task force supported by the European Society of Anaesthesiology and Intensive Care and the British Journal of Anaesthesia and focused on airway management in children under 1 yr of age. The guideline offers a series of recommendations based on meticulous methodology including multiple Delphi rounds to complement the sparse and scarce available evidence. Getting back from Brobdingnag, the land of giants with many guidelines available, this guideline represents a foundational cornerstone in the land of Lilliput.

Higher versus lower nasal continuous positive airway pressure for extubation of extremely preterm infants in Australia (ÉCLAT): a multicentre, randomised, superiority trial. THE LANCET. CHILD & ADOLESCENT HEALTH 2023; 7:844-851. [PMID: 38240784 DOI: 10.1016/s2352-4642(23)00235-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 09/07/2023] [Accepted: 09/08/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND Extremely preterm infants often require invasive mechanical ventilation, and clinicians aim to extubate these infants as soon as possible. However, extubation failure occurs in up to 60% of extremely preterm infants and is associated with increased mortality and morbidity. Nasal continuous positive airway pressure (nCPAP) is the most common post-extubation respiratory support, but there is no consensus on the optimal nCPAP level to safely avoid extubation failure in extremely preterm infants. We aimed to determine if higher nCPAP levels compared with standard nCPAP levels would decrease rates of extubation failure in extremely preterm infants within 7 days of their first extubation. METHODS In this multicentre, randomised, open-label controlled trial done at three tertiary perinatal centres in Australia, we assigned extremely preterm infants to extubation to either higher nCPAP (10 cmH2O) or standard nCPAP (7 cmH2O). Infants were eligible if they were born at less than 28 weeks' gestation, were receiving mechanical ventilation via an endotracheal tube, and were being extubated for the first time to nCPAP. Eligible infants must have received previous treatment with exogenous surfactant and caffeine. Infants were ineligible if they were planned to be extubated to a mode of respiratory support other than nCPAP, if they had a known major congenital anomaly that might affect breathing, or if ongoing intensive care was not being provided. Parents or guardians provided prospective, written, informed consent. Infants were maintained within an assigned nCPAP range for a minimum of 24 h after extubation (higher nCPAP group 9-11 cmH2O and standard nCPAP group 6-8 cmH2O). Randomisation was stratified by both gestation (22-25 completed weeks or 26-27 completed weeks) and recruiting centre. The primary outcome was extubation failure within 7 days and analysis was by intention to treat. This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12618001638224. FINDINGS Between March 3, 2019, and July 31, 2022, 483 infants were born at less than 28 weeks and admitted to the recruiting centres. 92 infants were not eligible, 172 were not approached, 65 families declined to participate, and 15 consented but were not randomly assigned. 139 infants were enrolled and randomly assigned, 70 to the higher nCPAP group and 69 to the standard nCPAP group. One infant in the higher nCPAP group was excluded from the analysis because consent was withdrawn after randomisation. 104 (75%) of 138 mothers were White. The mean gestation was 25·7 weeks (SD 1·3) and the mean birthweight was 777 grams (201). 70 (51%) of 138 infants were female. Extubation failure occurred in 24 (35%) of 69 infants in the higher nCPAP group and in 39 (57%) of 69 infants in the standard nCPAP group (risk difference -21·7%, 95% CI -38·5% to -3·7%). There were no significant differences in rates of adverse events between groups during the primary outcome period. Three patients died (two in the higher nCPAP group and one in the standard nCPAP group), pneumothorax occurred in one patient from each group, spontaneous intestinal perforation in three patients (two in the higher nCPAP group and one in the standard nCPAP group) and there were no events of pulmonary interstitial emphysema. INTERPRETATION Extubation of extremely preterm infants to higher nCPAP significantly reduced extubation failure compared with extubation to standard nCPAP, without increasing rates of adverse effects. Future larger trials are essential to confirm these findings in terms of both efficacy and safety.

Abstract
PROBLEM High-flow nasal cannula (HFNC) has been widely used in paediatric medicine as a non-invasive ventilation mode for respiratory support. However, the differences in its efficacy across different diseases and intervention types remain poorly understood. ELIGIBILITY CRITERIA An extensive literature search was performed across multiple academic databases to investigate the systematic reviews and meta-analyses of HFNC. SAMPLE This study included 35 systematic reviews and meta-analyses, which collectively examined 355 randomised controlled trials and assessed 51 outcome indicators. RESULTS The findings suggest that the existing clinical research evidence predominantly supports the therapeutic efficacy of HFNC. Notably, there is a significant focus on treating acute lower respiratory infection, hypoxaemia, bronchiolitis, and respiratory distress syndrome following extubation. However, concerning the respiratory status, the existing clinical research evidence mainly demonstrates the therapeutic benefits in post-extubation respiratory support and primary respiratory support. CONCLUSIONS The research on HFNC has witnessed significant expansion, primarily focusing on respiratory disorders, post-extubation respiratory support, conscious sedation, and related fields. The evidence mapping provides a systematic and comprehensive overview of the available evidence on HFNC therapy in paediatric patients. IMPLICATIONS This study systematically and comprehensively assessed the clinical subjects and populations involved in HFNC therapy. Notably, this study analyzed the trends, current status, and evidence gaps of research, and furnished decision-makers and relevant researchers with a more comprehensive reference basis.

Abstract
Neonatal endotracheal intubation is a challenging procedure with suboptimal success and adverse event rates. Systematically tracking intubation outcomes is imperative to understand both universal and site-specific barriers to intubation success and safety. The National Emergency Airway Registry for Neonates (NEAR4NEOS) is an international registry designed to improve neonatal intubation practice and outcomes that includes over 17,000 intubations across 23 international sites as of 2023. Methods to improve intubation safety and success include appropriately matching the intubation provider and situation and increasing adoption of evidence-based practices such as muscle relaxant premedication and video laryngoscope, and potentially new interventions such as procedural oxygenation.

Abstract
'Apnoeic oxygenation' describes the diffusion of oxygen across the alveolar-capillary interface in the absence of tidal respiration. Apnoeic oxygenation requires a patent airway, the diffusion of oxygen to the alveoli, and cardiopulmonary circulation. Apnoeic oxygenation has varied applications in adult medicine including facilitating tubeless anaesthesia or improving oxygenation when a difficult airway is known or anticipated. In the paediatric population, apnoeic oxygenation prolongs the time to oxygen desaturation, facilitating intubation. This application has gained attention in neonatal intensive care where intubation remains a challenging procedure. Difficulties are related to the infant's size and decreased respiratory reserve. In addition, policy changes have led to limited opportunities for operators to gain proficiency. Until recently, evidence of benefit of apnoeic oxygenation in the neonatal population came from a small number of infants recruited to paediatric studies. Evidence specific to neonates is emerging and suggests apnoeic oxygenation may increase intubation success and limit physiological instability during the procedure. The best way to deliver oxygen to facilitate apnoeic oxygenation remains an important question.

Abstract
Interest in 'resurrecting' the lifeless by supporting breathing has been described since ancient times. For centuries, methods of resuscitating animals, then humans and specifically the 'lifeless' neonate were debated and discussed. Over time, with experimentation and worldwide collaboration, endotracheal tubes and laryngoscopes specific to the newborn were created and their use refined. This historical work has meant that today, the neonatal community focuses on refining the science and the art of intubation for the benefit of the newborn; who, where, when and how to intubate, with what devices and medications, bringing about significant change in the area of neonatal intubation. Recent work has focused on alternatives to neonatal intubation as the risks of endotracheal intubation and mechanical ventilation have become clearer. Appreciating the history of neonatal intubation and its (somewhat cyclical) changes over time can show us how far we've come and how far we can still go in the resuscitation and respiratory support of newborns.

Abstract
BACKGROUND Cystic hygroma is a congenital lymphatic malformation. It may present as a huge mass in the neck, jeopardizing airway patency and prolonging intubation time, resulting in hypoventilation and hypoxemia. We used a high-flow nasal cannula to decrease the risk of hypoxemia and provide anesthesiologists sufficient time to perform tracheal intubation in young infants. CASE PRESENTATION A 33-day-old infant (height, 55 cm; weight, 5.05 kg) was diagnosed with macro-cystic hygroma of the right neck. Considering the progressive enlargement of the macrocystic hygroma and its impact on the airway, urgent intervention becomes imperative. Among the available treatment modalities, percutaneous cyst aspiration and sclerotherapy performed under ultrasound guidance represent the most commonly chosen approach. During the induction of general anesthesia, the otolaryngologists were on standby and prepared for emergency tracheotomy. The anesthesiologists chose total intravenous anesthesia induction while maintaining spontaneous breathing. A high-flow nasal cannula was used to keep the infant oxygenated, and endotracheal intubation was successfully performed using a C-MAC video laryngoscope and fiber-optic bronchoscope. CONCLUSIONS Airway management is the biggest challenge for anesthesiologists when delivering general anesthesia to infants with neck macro-cystic hygroma. Total intravenous anesthesia could be a choice for induction without considering compromised respiration and the side effects of inhalational anesthetics. A high-flow nasal cannula can be used in young infants to maintain oxygenation and allow anesthesiologists a longer time to perform intubation.

Abstract
Airway management is one of the most crucial aspects of neonatal care. The occurrence of a difficult airway is more common in neonates than in any other age group, and any neonatal intubation can develop into a difficult airway scenario. Understanding the intricacies of the difficult neonatal airway is paramount for healthcare professionals involved in the care of newborns. This chapter explores the multifaceted aspects of the difficult neonatal airway. We begin with a review of the definition and incidence of difficult airway in the neonate. Then, we explore factors contributing to a difficult neonatal airway. We next examine diagnostic considerations specific to the difficult neonatal airway, including prenatal imaging. Finally, we review management strategies. The importance of a multidisciplinary team approach and the role of communication and collaboration in achieving optimal outcomes are emphasized.

Abstract
High-flow nasal cannula (HFNC) oxygen therapy, which is important in noninvasive respiratory support, is increasingly being used in critically ill neonates with respiratory failure because it is comfortable, easy to setup, and has a low incidence of nasal trauma. The advantages, indications, and risks of HFNC have been the focus of research in recent years, resulting in the development of the application. Based on current evidence, we developed guidelines for HFNC in neonates using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). The guidelines were formulated after extensive consultations with neonatologists, respiratory therapists, nurse specialists, and evidence-based medicine experts. We have proposed 24 recommendations for 9 key questions. The guidelines aim to be a source of evidence and reference of HFNC oxygen therapy in clinical practice, and so that more neonates and their families will benefit from HFNC.

Abstract
Noninvasive respiratory support has gained significant popularity in neonatal units because of its potential to reduce lung injury associated with invasive mechanical ventilation. To minimize lung injury, clinicians aim to apply for noninvasive respiratory support as early as possible. However, the physiological background and the technology behind such support modes are not always clear, and many open questions remain regarding the indications of use and clinical outcomes. This narrative review discusses the currently available evidence for various noninvasive respiratory support modes applied in Neonatal Medicine in terms of physiological effects and indications. Reviewed modes include nasal continuous positive airway pressure, nasal high-flow therapy, noninvasive high-frequency oscillatory ventilation, nasal intermittent positive pressure ventilation (NIPPV), synchronized NIPPV and noninvasive neurally adjusted ventilatory assist. To enhance clinicians' awareness of each support mode's strengths and limitations, we summarize technical features related to the functioning mechanisms of devices and the physical properties of the interfaces commonly used for providing noninvasive respiratory support to neonates. We finally address areas of current controversy and suggest possible areas of research for implementing noninvasive respiratory support in neonatal intensive care units.

Abstract
OBJECTIVE Evaluate the association of short-term tracheal intubation (TI) outcomes with premedication in the NICU. STUDY DESIGN Observational single-center cohort study comparing TIs with full premedication (opiate analgesia and vagolytic and paralytic), partial premedication, and no premedication. The primary outcome is adverse TI associated events (TIAEs) in intubations with full premedication compared to those with partial or no premedication. Secondary outcomes included change in heart rate and first attempt TI success. RESULTS 352 encounters in 253 infants (median gestation 28 weeks, birth weight 1100 g) were analyzed. TI with full premedication was associated with fewer TIAEs aOR 0.26 (95%CI 0.1-0.6) compared with no premedication, and higher first attempt success aOR 2.7 (95%CI 1.3-4.5) compared with partial premedication after adjusting for patient and provider characteristics. CONCLUSION The use of full premedication for neonatal TI, including an opiate, vagolytic, and paralytic, is associated with fewer adverse events compared with no and partial premedication.

Abstract
Background Difficult airway management remains a critical procedure with life-threatening adverse events. Current guidelines suggest high-flow therapy by nasal cannulae (HFNC) as a preoxygenation device in this setting. However, there is an evidence gap to support this recommendation. Methods The PREOPTI-DAM study is an open-label, single-centre, randomised controlled phase 3 trial done at Nantes University Hospital, France. Patients were aged 18-90 years with one major or two minor criteria of anticipated difficult airway management, and requiring intubation for scheduled surgery, were eligible. Patients with body mass index >35 kg/m2 were excluded. Patients were randomly allocated (1:1) to receive 4-min preoxygenation by HFNC or facemask. Randomisation was stratified according to the intubation strategy (laryngoscopic versus fiberoptic intubation). The primary outcome was the incidence of oxygen desaturation ≤94% or of bag-mask ventilation during intubation. The primary and safety analyses included the intention to treat population. This trial is registered with ClinicalTrials.gov (NCT03604120) and EudraCT (2018-A00434-51). Findings From September 4 2018 to March 31 2021, 186 patients were enrolled and randomly assigned. One participant withdrew consent and 185 (99.5%) were included in the primary analysis (HFNC, N = 95; Facemask, N = 90). The incidence of the primary outcome was not significantly different between the HFNC and the facemask groups, respectively 2 (2%) versus 7 (8%); adjusted difference, -5.6 [95% confidence interval (CI), -11.8 to 0.6], P = 0.10. In the HFNC group, 76 patients (80%) versus 53 (59%) in the facemask group, reported good or excellent intubation experiences; adjusted difference 20.5 [95% CI, 8.3-32.8], P = 0.016. Comparing HFNC with facemask, severe complication occurred in 22 (23%) versus 27 (30%) patients (P = 0.29), and moderate complication in 14 (15%) versus 18 (20%) patients (P = 0.35). No death or cardiac arrest occurred during the study. Interpretation Compared with facemask, HFNC did not significantly reduce the incidence of desaturation ≤94% or bag-mask ventilation during anticipated difficult intubation but the trial was underpowered to rule out a clinically significant benefit. Patient satisfaction was improved with HFNC. Funding Nantes University Hospital and Fisher & Paykel Healthcare.

Abstract
INTRODUCTION Nasal high flow (nHF) improves the likelihood of successful neonatal intubation on the first attempt without physiological instability. The effect of nHF on cerebral oxygenation is unknown. The aim of this study was to compare cerebral oxygenation during endotracheal intubation in neonates receiving nHF and those receiving standard care. METHODS A sub-study of a multicentre randomized trial of nHF during neonatal endotracheal intubation. A subset of infants had near-infrared spectroscopy (NIRS) monitoring. Eligible infants were randomly assigned to nHF or standard care during the first intubation attempt. NIRS sensors provided continuous regional cerebral oxygen saturation (rScO2) monitoring. The procedure was video recorded, and peripheral oxygen saturation and rScO2 data were extracted at 2-second intervals. The primary outcome was the average difference in rScO2 from baseline during the first intubation attempt. Secondary outcomes included average rScO2 and rate of change of rScO2. RESULTS Nineteen intubations were analyzed (11 nHF; 8 standard care). Median (interquartile range [IQR]) postmenstrual age was 27 (26.5-29) weeks, and weight was 828 (716-1,135) g. Median change in rScO2 from baseline was -1.5% (-5.3 to 0.0) in the nHF group and -9.4% (-19.6 to -4.5) in the standard care group. rScO2 fell more slowly in infants managed with nHF compared with standard care: median (IQR) rScO2 change -0.08 (-0.13 to 0.00) % per second and -0.36 (-0.66 to -0.22) % per second, respectively. CONCLUSIONS In this small sub-study, regional cerebral oxygen saturation was more stable in neonates who received nHF during intubation compared with standard care.

Abstract
INTRODUCTION Nearly half of neonatal intubations are complicated by severe desaturation (≥20% decline in pulse oximetry saturation (SpO2)). Apnoeic oxygenation prevents or delays desaturation during intubation in adults and older children. Emerging data show mixed results for apnoeic oxygenation using high-flow nasal cannula (NC) during neonatal intubation. The study objective is to determine among infants ≥28 weeks' corrected gestational age (cGA) who undergo intubation in the neonatal intensive care unit (NICU) whether apnoeic oxygenation with a regular low-flow NC, compared with standard of care (no additional respiratory support), reduces the magnitude of SpO2 decline during intubation. METHODS AND ANALYSIS This is a multicentre, prospective, unblinded, pilot randomised controlled trial in infants ≥28 weeks' cGA who undergo premedicated (including paralytic) intubation in the NICU. The trial will recruit 120 infants, 10 in the run-in phase and 110 in the randomisation phase, at two tertiary care hospitals. Parental consent will be obtained for eligible patients prior to intubation. Patients will be randomised to 6 L NC 100% oxygen versus standard of care (no respiratory support) at time of intubation. The primary outcome is magnitude of oxygen desaturation during intubation. Secondary outcomes include additional efficacy, safety and feasibility outcomes. Ascertainment of the primary outcome is performed blinded to intervention arm. Intention-to-treat analyses will be conducted to compare outcomes between treatment arms. Two planned subgroup analyses will explore the influence of first provider intubation competence and patients' baseline lung disease using pre-intubation respiratory support as a proxy. ETHICS AND DISSEMINATION The Institutional Review Boards at the Children's Hospital of Philadelphia and the University of Pennsylvania have approved the study. Upon completion of the trial, we intend to submit our primary results to a peer review forum after which we plan to publish our results in a peer-reviewed paediatric journal. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Registry (NCT05451953).

Direct versus video laryngoscopy with standard blades for neonatal and infant tracheal intubation with supplemental oxygen: a multicentre, non-inferiority, randomised controlled trial. THE LANCET. CHILD & ADOLESCENT HEALTH 2023; 7:101-111. [PMID: 36436541 DOI: 10.1016/s2352-4642(22)00313-3] [Citation(s) in RCA: 18] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 10/14/2022] [Accepted: 10/14/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Tracheal intubation in neonates and infants is a potentially life-saving procedure. Video laryngoscopy has been found to improve first-attempt tracheal intubation success and reduce complications compared with direct laryngoscopy in children younger than 12 months. Supplemental periprocedural oxygen might increase the likelihood of successful first-attempt intubation because of an increase in safe apnoea time. We tested the hypothesis that direct laryngoscopy is not inferior to video laryngoscopy when using standard blades and supplemental oxygen is provided. METHODS We did a non-inferiority, international, multicentre, single-blinded, randomised controlled trial, in which we randomly assigned neonates and infants aged up to 52 weeks postmenstrual age scheduled for elective tracheal intubation to either direct laryngoscopy or video laryngoscopy (1:1 ratio, randomly assigned using a secure online service) at seven tertiary paediatric hospitals across Australia, Canada, Italy, Switzerland, and the USA. An expected difficult intubation was the main exclusion criteria. Parents and patients were masked to the assigned group of treatment. All infants received supplemental oxygen (1 L/Kg per min) during laryngoscopy until the correct tracheal tube position was confirmed. The primary outcome was the proportion of first-attempt tracheal intubation success, defined as appearance of end-tidal CO2 curve at the anaesthesia monitor, between the two groups in the modified intention-to-treat analysis. A 10% non-inferiority margin between direct laryngoscopy or video laryngoscopy was applied. The trial is registered with ClinicalTrials.gov (NCT04295902) and is now concluded. FINDINGS Of 599 patients assessed, 250 patients were included between Oct 26, 2020, and March 11, 2022. 244 patients were included in the final modified intention-to-treat analysis. The median postmenstrual age on the day of intubation was 44·0 weeks (IQR 41·0-48·0) in the direct laryngoscopy group and 46·0 weeks (42·0-49·0) in the video laryngoscopy group, 34 (28%) were female in the direct laryngoscopy group and 38 (31%) were female in the video laryngoscopy group. First-attempt tracheal intubation success rate with no desaturation was higher with video laryngoscopy (89·3% [95% CI 83·7 to 94·8]; n=108/121) compared with direct laryngoscopy (78·9% [71·6 to 86·1]; n=97/123), with an adjusted absolute risk difference of 9·5% (0·8 to 18·1; p=0·033). The incidence of adverse events between the two groups was similar (-2·5% [95% CI -9·6 to 4·6]; p=0·490). Post-anaesthesia complications occurred seven times in six patients with no difference between the groups. INTERPRETATION Video laryngoscopy with standard blades in combination with supplemental oxygen in neonates and infants might increase the success rate of first-attempt tracheal intubation, when compared with direct laryngoscopy with supplemental oxygen. The incidence of hypoxaemia increased with the number of attempts, but was similar between video laryngoscopy and direct laryngoscopy. Video laryngoscopy with oxygen should be considered as the technique of choice when neonates and infants are intubated.

Abstract
OBJECTIVE To assess the educational and clinical impact of a tiny baby intubation team (TBIT). STUDY DESIGN Retrospective study comparing endotracheal intubation (ETI) performed: pre-implementation of a TBIT (T1), 6 months post-implementation (T2), and 4 years post-implementation (T3). RESULTS Post-implementation (T2), first-attempt success rate in tiny babies increased (44% T1; 59% T2, p = 0.04; 56% T3, p = NS) and the proportion of ETIs performed by residents decreased (53% T1; 37% T2, p = 0.001; 45% T3, p = NS). After an educational quality improvement intervention (prioritizing non-tiny baby ETIs to residents, systematic simulation training and ETI using videolaryngoscopy), in T3 residents' overall (67% T1; 60% T2, p = NS; 79% T3, p = 0.02) and non-tiny baby ETI success rate improved (72% T1; 60% T2, p = NS; 82% T3, p = 0.02). CONCLUSION A TBIT improves success rate of ETIs in ELBW infants but decreases educational exposure of residents. Educational strategies may help maintain resident procedural competency without impacting on quality of care.

Abstract
BACKGROUND Determine if apneic oxygenation (AO) delivered via nasal cannula during the apneic phase of tracheal intubation (TI), reduces adverse TI-associated events (TIAEs) in children. METHODS AO was implemented across 14 pediatric intensive care units as a quality improvement intervention during 2016-2020. Implementation consisted of an intubation safety checklist, leadership endorsement, local champion, and data feedback to frontline clinicians. Standardized oxygen flow via nasal cannula for AO was as follows: 5 L/min for infants (< 1 year), 10 L/min for young children (1-7 years), and 15 L/min for older children (≥ 8 years). Outcomes were the occurrence of adverse TIAEs (primary) and hypoxemia (SpO2 < 80%, secondary). RESULTS Of 6549 TIs during the study period, 2554 (39.0%) occurred during the pre-implementation phase and 3995 (61.0%) during post-implementation phase. AO utilization increased from 23 to 68%, p < 0.001. AO was utilized less often when intubating infants, those with a primary cardiac diagnosis or difficult airway features, and patient intubated due to respiratory or neurological failure or shock. Conversely, AO was used more often in TIs done for procedures and those assisted by video laryngoscopy. AO utilization was associated with a lower incidence of adverse TIAEs (AO 10.5% vs. without AO 13.5%, p < 0.001), aOR 0.75 (95% CI 0.58-0.98, p = 0.03) after adjusting for site clustering (primary analysis). However, after further adjusting for patient and provider characteristics (secondary analysis), AO utilization was not independently associated with the occurrence of adverse TIAEs: aOR 0.90, 95% CI 0.72-1.12, p = 0.33 and the occurrence of hypoxemia was not different: AO 14.2% versus without AO 15.2%, p = 0.43. CONCLUSION While AO use was associated with a lower occurrence of adverse TIAEs in children who required TI in the pediatric ICU after accounting for site-level clustering, this result may be explained by differences in patient, provider, and practice factors. Trial Registration Trial not registered.

Abstract
OBJECTIVE In adult patients with acute respiratory failure, nasal high-flow (NHF) therapy at the time of intubation can decrease the duration of hypoxia. The objective of this pilot study was to calculate duration of peripheral oxygen saturation below 75% during single and multiple intubation attempts in order to inform development of a larger definitive trial. DESIGN AND SETTING This double-blinded randomised controlled pilot trial was conducted at a single, tertiary neonatal centre from October 2020 to October 2021. PARTICIPANTS Infants undergoing oral intubation in neonatal intensive care were included. Infants with upper airway anomalies were excluded. INTERVENTIONS Infants were randomly assigned (1:1) to have NHF 6 L/min, FiO2 1.0 or NHF 0 L/min (control) applied during intubation, stratified by gestational age (<34 weeks vs ≥34 weeks). MAIN OUTCOME MEASURES The primary outcome was duration of hypoxaemia of <75% up to the time of successful intubation, RESULTS: 43 infants were enrolled (26 <34 weeks and 17 ≥34 weeks) with 50 intubation episodes. In infants <34 weeks' gestation, median duration of SpO2 of <75% was 29 s (0-126 s) vs 43 s (0-132 s) (p=0.78, intervention vs control). Median duration of SpO2 of <75% in babies ≥34 weeks' gestation was 0 (0-32 s) vs 0 (0-20 s) (p=0.9, intervention vs control). CONCLUSION This pilot study showed that it is feasible to provide NHF during intubation attempts. No significant differences were noted in duration of oxygen saturation of <75% between groups; however, this trial was not powered to detect a difference. A larger, higher-powered blinded study is warranted.

Abstract
High flow nasal oxygen is a relatively new option for treating patients with respiratory failure, which decreases work of breathing, improves tidal volume, and modestly increases positive end expiratory pressure. Despite well-described physiologic benefits, the clinical impact of high flow nasal oxygen is still under investigation. In this article, we review the most recent findings on the clinical efficacy of high flow nasal oxygen in Type I, II, III, and IV respiratory failure within adult and pediatric patients. Additionally, we discuss studies across clinical settings, including emergency departments, intensive care units, outpatient, and procedural settings.

Abstract
In der Neonatologie ist bei der Anlage eines Endotrachealtubus häufig
mehr als ein Versuch notwendig. Dies führt oft, wegen der geringeren
funktionellen Residualkapazität und des höheren
Sauerstoffbedarfs, zu einer Sauerstoffentsättigung. Wiederholte
Intubationsversuche erhöhen das Komplikationsrisiko. Im Rahmen einer
australischen Studie wurde daher untersucht, ob eine begleitende nasale
