Brief Summary:
The purpose of this study is to determine if in preterm infants < 34 weeks' gestation at birth receiving respiratory support with continuous positive airway pressure (CPAP) or nasal cannula (NC), CPAP compared with NC will decrease the number of episodes with oxygen saturations less than 85% of ≥10 seconds in a 24-hour randomized controlled trial. This will be a randomized controlled trial with a 1:1 parallel allocation of infants to CPAP or NC oxygen using stratified permuted block design.

Detailed Description:

We hope to determine whether in preterm infants < 34 weeks' gestation at birth receiving respiratory support with continuous positive airway pressure (CPAP) or nasal cannula (NC), CPAP compared with NC will decrease the number of episodes with oxygen saturations less than 85% of ≥10 seconds in a 24-hour randomized controlled trial.

This study will include preterm infants < 34 weeks' gestation on respiratory support via CPAP with a PEEP ≤ 5 and FiO2 ≤ 30%. There will be three randomization strata [≥ 22+0/7 to ≤ 25+6/7 weeks, ≥ 26+0/7 to ≤ 29+6/7 weeks, and ≥ 30+0/7 to ≤ 33+6/7 weeks. The purpose of stratification is to ensure an appropriate distribution of risk between study arms. This study will not be powered to detect outcome differences within or between strata.

Following informed consent, randomization, stratified by gestational age at delivery, will be performed using sequentially numbered sealed opaque envelopes. Each envelope will indicate either Treatment group (CPAP group) or Control group (NC group). The envelope will only be opened after informed consent has been obtained and just before starting the study on each infant.

This will be a single center randomized controlled trial with a 1:1 parallel allocation of infants to CPAP or NC oxygen using stratified permuted block design. 15-30 minutes will be provided as a washout period at the beginning of the intervention, followed by 24 hours on the intervention. Infants enrolled must meet CPAP stability criteria that are based on prior randomized clinical trials of weaning from CPAP to NC.

All infants enrolled in the study will have routine monitoring, uniform target saturation ranges of 91-95% with alarm limits set at 88-95%, and standard care for the duration of the study. The high alarm limit will be increased to 100% if an infant is weaned to 21% FiO2. Supplemental FiO2 will be titrated per unit routine to achieve goal target saturations. Pulse oximetry recordings will be downloaded using ixTrend (iexcellence, Wildau, Germany) software to a secure computer system or via Bedmaster software for later data analysis. The target oxygen saturations (91 to 95%) are based on data from the meta-analysis of randomized controlled trials of oxygen saturation targets which included data on 4911 infants from the SUPPORT, COT, and BOOST II trials.

Primary and secondary outcomes are described below. Other safety outcomes include recordings of episodes of bradycardia and circumstances surrounding the event. Pulse oximetry recordings will be downloaded using ixTrend software to a secure computer system for later data analysis. Abdominal and cerebral NIRS will also be performed with subsequent data analysis..

Arm Intervention/treatment
Experimental: Continuous positive airway pressure
Continuous positive airway pressure (CPAP) with blended oxygen delivered by binasal prongs or nasal mask.
Procedure: Continuous positive airway pressure
After study entry, CPAP will be provided via mask or binasal prongs in order to have a relatively uniform CPAP delivery system among infants in the treatment group. Bubble CPAP will be preferred over other modes of CPAP delivery. A PEEP of 5 will be used for uniformity.
Other Name: CPAP

Active Comparator: Nasal Cannula
Blended oxygen delivered by nasal cannula (NC).
Procedure: Nasal Cannula
After study entry, flow will be set to 0.5 L/kg with 1L maximum while on NC during the study period to reduce the risk of inadvertent PEEP with higher flows. Initial FiO2 can be titrated to achieve target saturations, and may be increased up to 100% while on NC.
Other Name: NC




Primary Outcome Measures :
  1. The number of episodes with oxygen saturations less than 85% for ≥ 10 seconds [ Time Frame: 24 hours of intervention ]

Secondary Outcome Measures :
  1. The coefficient of variability of oxygen saturations (relative standard deviation) [ Time Frame: 24 hours of intervention ]
    The coefficient of variation is a standardized measure of dispersion of a frequency distribution defined as the ratio of the standard deviation to the mean. It will be used in this study to assess the stability of oxygen saturations.

  2. The proportion of time with oxygen saturations > 95 % among infants requiring supplemental oxygen [ Time Frame: 24 hours of intervention ]
  3. The proportion of time spent outside oxygen saturation target ranges (91-95%) among infants requiring supplemental oxygen [ Time Frame: 24 hours of intervention ]
  4. The proportion of time with oxygen saturations less than 85% [ Time Frame: 24 hours of intervention ]
  5. The median supplemental oxygen concentration [ Time Frame: 24 hours of intervention ]
  6. The median transcutaneous carbon dioxide value [ Time Frame: 24 hours of intervention ]
  7. The number of episodes (≥ 10 seconds) with oxygen saturations less than 80 % [ Time Frame: 24 hours of intervention ]
  8. The number of recorded episodes (≥ 10 seconds) of bradycardia < 100/min [ Time Frame: 24 hours of intervention ]
  9. The median cNIRS value [ Time Frame: 24 hours of intervention ]
    Median cerebral near-infrared spectroscopy value during the 24 hour intervention period

  10. The median aNIRS value [ Time Frame: 24 hours of intervention ]
    Median abdominal near-infrared spectroscopy value during the 24 hour intervention period
