Query!
Description of intervention(s) / exposure
In the intervention arm initial respiratory support immediately after birth is provided using a nasal mask for CPAP and supplemental oxygen. In the control arm initial respiratory support is provided using a face mask.
The duration of this support is between the time of birth and transfer to the NICU, about 10-20 minutes.
The treatment will be administered by the neonatal team, typically the neonatal registrar, fellow, nurse practitioner, or consultant, depending on the composition of the team at birth. Note, all infants born at less than 27 weeks and all twins born at less than 29 weeks will have a consultant present at the birth.
Our primary outcome is the proportion of infants that are managed with CPAP only in the nasal CPAP versus face mask CPAP groups. Failure of CPAP only treatment means that the infant received positive pressure ventilation via a facemask or an endotracheal tube. Success of the intervention will be recorded in the existing medical records.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This is an unblinded, randomised controlled trial, at Monash Medical Centre (MMC) Clayton.
Once the neonatal resuscitation team has been called to attend the pending birth, the unborn patient will be randomised to nasal CPAP or facemask CPAP for initial respiratory support. Randomisation will be allocated by a member of the research team via the RedCAP web-based randomisation tool. RedCAP is a HIPAA-compliant, secure web application for building and managing databases. Monash Health Translational Precinct is an institutional partner and a member of the RedCAP Consortium. Prior to the impending birth, investigators will use RedCAP generate a study number, randomise the unborn infant, and tell the clinical team the treatment allocation. We have used RedCAP process to successfully to randomise infants requiring neonatal resuscitation in the Baby DUCC RCT (ACTRN12618000621213). Infants will be stratified by gestational age, 23 and 0/7 to 27 and 6/7 weeks and 28 and 0/7 to 31 and 6/7 weeks.

Statistical methods / analysis
Each patient will be assigned a study number and de-identified information will be entered into a database for analysis (Microsoft Excel, USA and IBM SPSS, USA). We will use means and SDs for normally distributed continuous variables, and medians and IQRs for variables with skewed distribution.
The primary outcome will be determined using a Fisher’s Exact test. Continuous variables will be compared using an independent samples t-test if normally distributed and a 2-sided Mann-Whitney U test for non-normally distributed data. Categorical variables will be compared using the Fisher’s exact test. Statistical significance will be considered at p<0.05.
Ninety percent of infants <32 weeks’ will initiate breathing by 1 minute after birth, breathing at an average of 25 seconds after birth. In published studies that are consistent with our data from our ongoing CLD QI initiative at Monash (2017-2019), over 60% of VPTI will require PPV and 25% will require intubation prior to transfer to the NICU. In the delivery room at Monash in 2019, 97% of eligible infants received respiratory support, 33% received CPAP as their maximum level of support, and 64% required PPV and/or intubation.
We hypothesise that 75% of infants who receive nasal CPAP as the initial respiratory management will be successfully managed on CPAP, defined as not requiring escalation to PPV and/or intubation in the delivery room, versus 45% of infants who receive facemask CPAP as initial respiratory management. Assuming an alpha of 0.05 and 90% power, we would need to study 122 infants, 61 in each arm. We anticipate that 10% of infants will be apneic at birth and will immediately require positive pressure ventilation as the first mode of respiratory support and that 3% of infants will not require any respiratory support. Therefore, we plan to study 150 infants, 75 in each arm. We will stratify for gestational age, 23 and 0/7 days to 27 6/7 days and 28 and 0/7 days to 31 and 6/7 days, and specify that each arm must have a minimum of 25 born at <28 weeks gestational age.
Over 180 eligible infants are born at MMC annually, including 55 infants born at <28 weeks’ gestational age. We anticipate requiring 18 months to complete enrolment and an additional 4 months to follow the last enrolled infant until hospital discharge.

Summary
Brief summary
Non-invasive, continuous positive airway pressure (CPAP) immediately after birth of a very preterm infant (“VPTI,” <32 weeks’ gestational age at birth) is currently recommended as the standard of care during the stabilisation of preterm infants following birth. After birth, the infant must rapidly transition from a fluid filled lung, and dependence on the placenta for oxygenation and the elimination of carbon dioxide, to an aerated lung that successfully exchanges gases. CPAP supports the transition from fetal to newborn physiology by providing a distending pressure to the lung, thus maintaining a functional residual capacity (FRC) and enabling oxygenation and ventilation.
Preterm infants who are successfully managed with CPAP versus mechanical ventilation via an endotracheal tube have increased survival without chronic lung disease, which improves long-term neurodevelopmental outcomes. Caffeine, and minimally invasive surfactant therapy (MIST) are other key treatments after admission to the NICU to avoid intubation and mechanical ventilation. Following stabilisation on CPAP, caffeine and MIST may be administered to further optimise respiratory support and reduce the risk of requiring intubation and mechanical ventilation, ultimately reducing the incidence of death and chronic lung disease in our patients.
97% of VPTIs at Monash require respiratory support to facilitate stabilisation. Current neonatal resuscitation training programs advocate a trial of CPAP via a facemask that covers the infant’s nose and mouth. An adequate seal is difficult to achieve and the use of a facemask has the additional adverse effect of high compressive forces being applied to the infant’s face and head during resuscitation regardless of which brand of facemask is used, and even with the use of adjunct respiratory monitoring. Ninety percent of VPTIs will initiate spontaneous breathing by 1 minute after birth. Despite VPTIs commonly having a good respiratory drive, respiratory support is nearly always indicated because of respiratory distress syndrome caused by the immature lungs. In this situation, facemask CPAP has a high failure rate due to stimulation of the trigeminal nerves which cause apnea, bradycardia, and hypoxia.
Our multidisciplinary team has over a year of experience with nasal CPAP at birth and we have equipoise between providing initial respiratory support in the delivery room with nasal CPAP versus facemask CPAP. We believe that nasal CPAP may be a more effective method of supporting the VPTI than facemask CPAP, specifically maintaining adequate spontaneous breathing and reducing the need for PPV, supplemental oxygen, and intubation in the delivery room. We believe a randomised controlled trial is warranted to test this hypothesis, in order to improve outcomes for high-risk, preterm infants, inform local practice, and provide critically important evidence to the global neonatal community.
