RESUMO
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.

Abnormal temperature in preterm infants is associated with increased morbidity and mortality. Infants born prematurely are at risk of abnormal temperature immediately after birth in the delivery room (DR). The World Health Organization (WHO) recommends that the temperature of newly born infants is maintained between 36.5-37.5oC after birth. When caring for very preterm infants, the International Liaison Committee on Resuscitation (ILCOR) recommends using a combination of interventions to prevent heat loss. While hypothermia remains prevalent, efforts to prevent it have increased the incidence of hyperthermia, which may also be harmful. Delayed cord clamping (DCC) for preterm infants has been recommended by ILCOR since 2015. Little is known about the effect of timing of DCC on temperature, nor have there been specific recommendations for thermal care before DCC. This review article focuses on the current evidence and recommendations for thermal care in the DR, and considers thermoregulation in the context of emerging interventions and future research directions. IMPACT: Abnormal temperature is common amongst very preterm infants after birth, and is an independent risk factor for mortality. The current guidelines recommend a combination of interventions to prevent heat loss after birth. Despite this, abnormal temperature is still a problem, across all climates and economies. New and emerging delivery room practice (i.e., delayed cord clamping, mobile resuscitation trolleys, early skin to skin care) may have an effect on infant temperature. This article reviews the current evidence and recommendations, and considers future research directions.

BACKGROUND: The impact of the permissive hypotension approach in clinically well infants on regional cerebral oxygen saturation (rScO2) and autoregulatory capacity (CAR) remains unknown. METHODS: Prospective cohort study of blinded rScO2 measurements within a randomized controlled trial of management of hypotension (HIP trial) in extremely preterm infants. rScO2, mean arterial blood pressure, duration of cerebral hypoxia, and transfer function (TF) gain inversely proportional to CAR, were compared between hypotensive infants randomized to receive dopamine or placebo and between hypotensive and non-hypotensive infants, and related to early intraventricular hemorrhage or death. RESULTS: In 89 potentially eligible HIP trial patients with rScO2 measurements, the duration of cerebral hypoxia was significantly higher in 36 hypotensive compared to 53 non-hypotensive infants. In 29/36 hypotensive infants (mean GA 25 weeks, 69% males) receiving the study drug, no significant difference in rScO2 was observed after dopamine (n = 13) compared to placebo (n = 16). Duration of cerebral hypoxia was associated with early intraventricular hemorrhage or death. Calculated TF gain (n = 49/89) was significantly higher reflecting decreased CAR in 16 hypotensive compared to 33 non-hypotensive infants. CONCLUSIONS: Dopamine had no effect on rScO2 compared to placebo in hypotensive infants. Hypotension and cerebral hypoxia are associated with early intraventricular hemorrhage or death. IMPACT: Treatment of hypotension with dopamine in extremely preterm infants increases mean arterial blood pressure, but does not improve cerebral oxygenation. Hypotensive extremely preterm infants have increased duration of cerebral hypoxia and reduced cerebral autoregulatory capacity compared to non-hypotensive infants. Duration of cerebral hypoxia and hypotension are associated with early intraventricular hemorrhage or death in extremely preterm infants. Since systematic treatment of hypotension may not be associated with better outcomes, the diagnosis of cerebral hypoxia in hypotensive extremely preterm infants might guide treatment.

BACKGROUND: High flow nasal cannulae (HFNC) are small, thin, tapered binasal tubes that deliver oxygen or blended oxygen/air at gas flows of more than 1 L/min. HFNC are increasingly being used as a form of non-invasive respiratory support for preterm infants. OBJECTIVES: To compare the safety and efficacy of HFNC with other forms of non-invasive respiratory support in preterm infants. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 1), MEDLINE via PubMed (1966 to 1 January 2016), EMBASE (1980 to 1 January 2016), and CINAHL (1982 to 1 January 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA: Randomised or quasi-randomised trials comparing HFNC with other non-invasive forms of respiratory support in preterm infants immediately after birth or following extubation. DATA COLLECTION AND ANALYSIS: The authors extracted and analysed data, and calculated risk ratio, risk difference and number needed to treat for an additional beneficial outcome. MAIN RESULTS: We identified 15 studies for inclusion in the review. The studies differed in the interventions compared (nasal continuous positive airway pressure (CPAP), nasal intermittent positive pressure ventilation (NIPPV), non-humidified HFNC, models for delivering HFNC), the gas flows used and the indications for respiratory support (primary support from soon after birth, post-extubation support, weaning from CPAP support). When used as primary respiratory support after birth compared to CPAP (4 studies, 439 infants), there were no differences in the primary outcomes of death (typical risk ratio (RR) 0.36, 95% CI 0.01 to 8.73; 4 studies, 439 infants) or chronic lung disease (CLD) (typical RR 2.07, 95% CI 0.64 to 6.64; 4 studies, 439 infants). HFNC use resulted in longer duration of respiratory support, but there were no differences in other secondary outcomes. One study (75 infants) showed no differences between HFNC and NIPPV as primary support. Following extubation (total 6 studies, 934 infants), there were no differences between HFNC and CPAP in the primary outcomes of death (typical RR 0.77, 95% CI 0.43 to 1.36; 5 studies, 896 infants) or CLD (typical RR 0.96, 95% CI 0.78 to 1.18; 5 studies, 893 infants). There was no difference in the rate of treatment failure (typical RR 1.21, 95% CI 0.95 to 1.55; 5 studies, 786 infants) or reintubation (typical RR 0.91, 95% CI 0.68 to 1.20; 6 studies, 934 infants). Infants randomised to HFNC had reduced nasal trauma (typical RR 0.64, 95% CI 0.51 to 0.79; typical risk difference (RD) -0.14, 95% CI -0.20 to -0.08; 4 studies, 645 infants). There was a small reduction in the rate of pneumothorax (typical RR 0.35, 95% CI 0.11 to 1.06; typical RD -0.02, 95% CI -0.03 to -0.00; 5 studies 896 infants) in infants treated with HFNC. Subgroup analysis found no difference in the rate of the primary outcomes between HFNC and CPAP in preterm infants in different gestational age subgroups, though there were only small numbers of extremely preterm and late preterm infants. One trial (28 infants) found similar rates of reintubation for humidified and non-humidified HFNC, and two other trials (100 infants) found no difference between different models of equipment used to deliver humidified HFNC. For infants weaning from non-invasive respiratory support (CPAP), two studies (149 infants) found that preterm infants randomised to HFNC had a reduced duration of hospitalisation compared with infants who remained on CPAP. AUTHORS' CONCLUSIONS: HFNC has similar rates of efficacy to other forms of non-invasive respiratory support in preterm infants for preventing treatment failure, death and CLD. Most evidence is available for the use of HFNC as post-extubation support. Following extubation, HFNC is associated with less nasal trauma, and may be associated with reduced pneumothorax compared with nasal CPAP. Further adequately powered randomised controlled trials should be undertaken in preterm infants comparing HFNC with other forms of primary non-invasive support after birth and for weaning from non-invasive support. Further evidence is also required for evaluating the safety and efficacy of HFNC in extremely preterm and mildly preterm subgroups, and for comparing different HFNC devices.

BACKGROUND: Pneumothorax occurs more frequently in the neonatal period than at any other time of life and is associated with increased mortality and morbidity. It may be treated with either needle aspiration or insertion of a chest tube. The former consists of aspiration of air with a syringe through a needle or an angiocatheter, usually through the second or third intercostal space in the midclavicular line. The chest tube is usually placed in the anterior pleural space passing through the sixth intercostal space into the pleural opening, turned anteriorly and directed to the location of the pneumothorax, and then connected to a Heimlich valve or an underwater seal with continuous suction. OBJECTIVES: To compare the efficacy and safety of needle aspiration and intercostal tube drainage in the management of neonatal pneumothorax. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2015, Issue 11), MEDLINE via PubMed (1966 to 30 November 2015), EMBASE (1980 to 30 November 2015), and CINAHL (1982 to 30 November 2015). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA: Randomised controlled trials, quasi-randomised controlled trials and cluster trials comparing needle aspiration (either with the needle or angiocatheter left in situ or removed immediately after aspiration) to intercostal tube drainage in newborn infants with pneumothorax. DATA COLLECTION AND ANALYSIS: For each of the included trial, two authors independently extracted data (e.g. number of participants, birth weight, gestational age, kind of needle and chest tube, choice of intercostal space, pressure and device for drainage) and assessed the risk of bias (e.g. adequacy of randomisation, blinding, completeness of follow-up). The primary outcomes considered in this review are mortality during the neonatal period and during hospitalisation. MAIN RESULTS: One randomised controlled trial (72 infants) met the inclusion criteria of this review. We found no differences in the rates of mortality (risk ratio (RR) 1.50, 95% confidence interval (CI) 0.27 to 8.45) or complications related to the procedure. After needle aspiration, the angiocatheter was left in situ (mean 27.1 hours) and not removed immediately after the aspiration. The angiocatheter was in place for a shorter duration than the intercostal tube (mean difference (MD) -11.20 hours, 95% CI -15.51 to -6.89). None of the 36 newborns treated with needle aspiration with the angiocatheter left in situ required the placement of an intercostal tube drainage. Overall, the quality of the evidence supporting this finding is low. AUTHORS' CONCLUSIONS: At present there is insufficient evidence to determine the efficacy and safety of needle aspiration versus intercostal tube drainage in the management of neonatal pneumothorax. Randomised controlled trials comparing the two techniques are warranted.

AIM: Newborns are placed supine for umbilical venous catheter insertion, and catheter tip position is confirmed with X-ray. Umbilical venous catheters are considered correctly positioned when the tip is in the inferior vena cava; however, frequently, the catheter tip enters the portal venous circulation. We wished to determine whether placing infants on their right side, rather than on the back, for umbilical venous catheter insertion results in more correctly placed catheters. METHODS: Newborns were randomised to be placed on their back, or turned onto their right side for catheter insertion. Primary outcome was correct catheter tip position on X-ray (visible in the midline at diaphragm level). RESULTS: Umbilical venous catheter insertion was successful in all infants enrolled. There was no difference in the proportion of correctly positioned catheters between the groups [back 23/44 (52%) versus right side 27/44 (61%), p = 0.389]. More infants randomised to back had the catheter tip in the portal circulation [back 13/44 (30%) versus right side 5/44 (11%), p = 0.034]. CONCLUSION: Positioning newborn infants on their right side did not result in more correctly placed umbilical venous catheters. The procedure was well tolerated and reduced the rate of tip insertion into the portal venous circulation.

BACKGROUND: At birth, infants' lungs are fluid-filled; this fluid must be replaced by air to allow for effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volume in the lungs. OBJECTIVES: To assess the efficacy of initial sustained (> one second duration) lung inflation compared to standard inflations (≤ one second) in newly born infants receiving resuscitation with intermittent PPV. SEARCH METHODS: We searched on PubMed (1966 to 1 February 2015), EMBASE (1980 to 1 February 2015) and the Cochrane Central Register of Controlled Trials (the Cochrane Library 2015). No language restrictions were applied. We searched the abstracts of the Pediatric Academic Societies (PAS) from 2000 to 2014. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs comparing giving initial sustained lung inflations (SLI) vs. standard inflations to infants receiving resuscitation with PPV at birth. DATA COLLECTION AND ANALYSIS: We assessed methodological quality of the included trials using Cochrane Effective Practice and Organisation of Care Group (EPOC) criteria (assessing randomisation, blinding, loss to follow-up and handling of outcome data). We evaluated the treatment effect using a fixed-effect model using risk ratio for categorical data and using mean, standard deviation (SD) and weighted mean difference (WMD) for continuous data. MAIN RESULTS: Two trials enrolling 352 infants met our inclusion criteria. There were no differences in the rates of mortality during hospitalisation (RR 1.59, 95% CI 0.81 to 3.10; two trials, 352 infants), intubation in the first three days of life (RR 0.85, 95% CI 0.72 to 1.02; two trials, 352 infants) or chronic lung disease (RR 1.06, 95% CI 0.79 to 1.42; two trials, 349 infants) between infants who received sustained versus standard inflations. The rate of patent ductus arteriosus (reported as need for pharmacological treatment) was higher in the sustained inflation group (RR 1.27, 95% CI 1.03 to 1.56; two trials, 352 infants). AUTHORS' CONCLUSIONS: At present there is insufficient evidence from clinical trials to determine the efficacy and safety of initial sustained lung inflation for newborn infants resuscitated with PPV. RCTs comparing PPV with and without sustained inflations at neonatal resuscitation are warranted.

AIM: Many drugs are not licensed for use in children and drugs that are licensed may be given to them in an unapproved manner. We wanted to determine the extent of unlicensed and off-label prescribing in our neonatal intensive care unit (NICU). METHODS: All infants admitted to our tertiary-level NICU over 2 months were prospectively studied. We recorded demographic data, and all the drugs prescribed and compared the use of each drug to the licensed indications in the Summary of Product Characteristics. RESULTS: All the 110 infants admitted received a prescribed drug, with 69 different drugs prescribed, a median (IQR) of four (range: 3-11) drugs each. Just less than a fifth (19%) were unlicensed and 39% were off-label, with 45 infants (44%) receiving both an unlicensed and off-label drug, three (3%) receiving an unlicensed drug and 35 (32%) receiving just an off-label drug. Most infants <32 weeks received unlicensed (91%) and off-label (94%) drugs, and all infants <28 weeks received an unlicensed and an off-label drug. CONCLUSION: Most drugs prescribed to newborns are unlicensed or used for off-label reasons. Many infants, and the majority of preterm infants, admitted to our NICU received unlicensed and off-label drugs.

Fetal thyrotoxicosis is a rare condition with high morbidity and mortality. It may complicate pregnancies in women with a history of Graves disease (GD) when transplacental passage of maternal TSH receptor antibodies stimulate the fetal thyroid gland and cause hyperthyroidism. We report the case of a 34-year-old woman with a history of GD and prior thyroidectomy, where fetal thyrotoxicosis at 21 weeks of gestation was suspected due to prenatal ultrasound findings of cardiac failure and fetal goiter. She was treated with high-dose carbimazole and followed closely by a multidisciplinary team. Her baby was delivered in good condition at 34 weeks' gestation and developed hyperthyroidism in the days after birth, which was successfully treated medically. This case highlights the importance of awareness of the condition among women with a history of GD, as well as the necessity for prompt diagnosis and treatment of this complex disease.
RESUMO
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.

OBJECTIVE: To determine the proportion of infants who had the tasks recommended in the neonatal resuscitation guidelines performed within 30 and 60 seconds of birth, and the time taken to perform each task. STUDY DESIGN: From video recordings in delivery rooms, we determined the time from birth and arrival on a resuscitation table to warm, assess heart rate (HR), attach an oximeter, and provide respiratory support for each infant. We determined the proportion of infants who had these tasks completed by 30 and 60 seconds, and the median time taken to perform each task. RESULTS: We reviewed and analyzed data from 189 infants (median gestational age, 29 weeks [IQR, 27-34 weeks]; median birth weight, 1220 g [IQR, 930-2197 g]). Twelve infants (6%) were not on the resuscitation table within 30 seconds of birth. Less than 10% of infants were placed in polyethylene bags or had their HR determined by 30 seconds. By 60 seconds, 48% were in polyethylene bags, 33% had their HR determined, 38% received respiratory support, and 60% had an oximeter attached. The median time taken to perform all tasks was greater than that recommended in the guidelines. CONCLUSION: Most newborns were not managed within the time frame recommended in resuscitation guidelines. The recommended 30- and 60-second intervals may be too short.

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.

Resuscitation of newborns has been described since ancient times and is among the most commonly performed emergency medical interventions. The International Liaison Committee on Resuscitation first made recommendations on resuscitation in newborns in 1999. Over the last decade, new research and careful review of the available evidence have resulted in substantial changes to these recommendations - in particular, regarding the assessment of colour, giving supplemental oxygen, suctioning infants born through meconium-stained liquor, confirming endotracheal tube position, the use of pulse oximetry, giving CPAP to premature infants, keeping preterm infants warm using polyethylene wrapping and cooling term infants with encephalopathy. This process has also highlighted the paucity of evidence to support much of the care given to infants in the delivery room and the need for research to refine our techniques.

Many of the recommendations for newborn care in the delivery room (DR) are based on retrospective observational studies, preclinical studies of mannequins or animal models, and expert opinion. Conducting DR research is challenging. Many deliveries occur in fraught circumstances with little prior warning, making it difficult to get prospective consent from parents and buy-in from clinicians. Many DR interventions are difficult to mask for the purpose of a clinical trial and it is not easy to identify appropriate outcomes for studies that are sufficiently "short-term" that they are likely to be influenced by the intervention, yet sufficiently "long-term" to be considered clinically important. However, despite these challenges, much information has been accrued from clinical studies in recent years. In this article, we outline our experience of conducting clinical research in the DR. In our initial studies almost 20 years ago, we found wide variation in the equipment used both nationally and internationally, reflecting the paucity of evidence to support practice. This started a journey that has included many observational studies and randomized controlled trials that have attempted to refine how we care for newborn infants in the DR. Each has given further information and, inevitably, raised many more questions about the approach to caring for newborns in the DR.

Introduction: Around 140 million children are born every year and post-natal transition is uncomplicated in the vast majority. However, around 5%-15% of neonates receive supportive interventions during transition. Recent data on the interventions used is scarce. More data on the frequencies with which these interventions are used is needed to evaluate neonatal resuscitation, guide recommendations and to generate hypotheses for further research. The following protocol describes an international, multicentre survey on the interventions currently applied during neonatal resuscitation. Objectives: To determine the frequencies at which different supportive interventions recommended by European Resuscitation Council (ERC) guidelines for neonatal resuscitation are used. To compare the frequencies between hospitals and patient groups and to investigate possible factors influencing any differences found. Methods: Participating hospitals will collect data on all interventions performed during neonatal resuscitation over a period of 6 months. All hospitals providing perinatal care are eligible regardless of size and designated level of neonatal care. Every neonate requiring more interventions than basic drying and tactile stimulation during the first 30â min of life will be included. The targeted sample size is at least 4,000 neonates who receive interventions. After anonymization, the data is pooled in a common database and descriptive and statistical analysis is performed globally and in subgroups. Possible correlations will be investigated with phi coefficient and chi square testing. Ethics and dissemination: Consent of the institutional review board of the Technical University Dresden was obtained for the local data collection under the number BO-EK-198042022. Additionally, approval of local ethical or institutional review boards will be obtained by the participating hospitals if required. Results will be published in peer-reviewed journals and presented at suitable scientific conferences.
RESUMO
OBJECTIVE: To investigate whether infants < 29 weeks gestation who receive positive pressure ventilation (PPV) immediately after birth with a T-piece have higher oxygen saturation (SpO2) measurements at 5 minutes than infants ventilated with a self inflating bag (SIB). STUDY DESIGN: Randomized, controlled trial of T-piece or SIB ventilation in which SpO2 was recorded immediately after birth from the right hand/wrist with a Masimo Radical pulse oximeter, set at 2-second averaging and maximum sensitivity. All resuscitations started with air. RESULTS: Forty-one infants received PPV with a T-piece and 39 infants received PPV with a SIB. At 5 minutes after birth, there was no significant difference between the median (interquartile range) SpO2 in the T-piece and SIB groups (61% [13% to 72%] versus 55% [42% to 67%]; P = .27). More infants in the T-piece group received oxygen during delivery room resuscitation (41 [100%] versus 35 [90%], P = .04). There was no difference in the groups in the use of continuous positive airway pressure, endotracheal intubation, or administration of surfactant in the delivery room. CONCLUSION: There was no significant difference in SpO2 at 5 minutes after birth in infants < 29 weeks gestation given PPV with a T-piece or a SIB as used in this study.

AIMS: To compare the admission temperature of infants treated with polyethylene bags alone to infants treated with exothermic mattresses in addition to bags in the delivery room. METHODS: We prospectively studied infants born at <31 weeks' gestation who were placed in bags at birth. Some infants were also placed on mattresses. Admission axillary temperatures were measured in all infants on admission to the neonatal intensive care. We compared the temperatures of infants treated with bags alone to those treated with mattresses and bags. RESULTS: We studied 43 infants: 15 were treated with bags while 28 were treated with a bag and mattress. Mean admission temperature was similar between the groups. Hypothermia and hyperthermia occurred more frequently in infants treated with a bag and mattress, and more infants treated with a bag had admission temperatures 36.5-37.5°C. CONCLUSION: The use of exothermic mattresses in addition to polyethylene bags, particularly in younger, smaller newborns, may result in more hypothermia and hyperthermia on admission. A randomised controlled trial is necessary to determine which strategy results in more infants having admission temperatures in the normal range.

Neonatal resuscitation algorithms recommend assessing breathing and heart rate (HR) of newborns and giving respiratory support when one or both are unsatisfactory. Recommendations also state that preterm infants may be supported with continuous positive airway pressure rather than routinely intubated for positive pressure ventilation (PPV). We wished to describe the prevalence and time of initiation of respiratory support of extremely preterm and extremely low birthweight (ELBW) infants at our hospital. We reviewed videos of 55 infants. Although most were breathing, practically all newly born extremely preterm ELBW infants were given respiratory support soon after arrival to the resuscitation cot. For the majority, this was done without knowing the HR. The majority received PPV; again, this was often done without knowing the HR. A quarter of infants were managed without any PPV.
