BACKGROUND BACKGROUND
Optimal starting oxygen concentration for delivery room resuscitation of extremely preterm infants (<29 weeks) remains unknown, with recommendations of 21-30% based on uncertain evidence. Individual patient randomized trials designed to answer this question have been hampered by poor enrolment.
HYPOTHESIS OBJECTIVE
It is feasible to compare 30% vs. 60% starting oxygen for delivery room resuscitation of extremely preterm infants using a change in local hospital policy and deferred consent approach.
STUDY DESIGN METHODS
Prospective, single-center, feasibility study, with each starting oxygen concentration used for two months for all eligible infants.
POPULATION METHODS
Infants born at 23 + 0-28 + 6 weeks' gestation who received delivery room resuscitation. Study interventions: Initial oxygen at 30% or 60%, increasing by 10-20% every minute for heart rate < 100 bpm, or increase to 100% for chest compressions.
PRIMARY OUTCOME METHODS
Feasibility, defined by (i) achieving difference in cumulative supplied oxygen concentration between groups, and (ii) post-intervention rate consent >50%.
RESULTS RESULTS
Thirty-four infants were born during a 4-month period; consent was obtained in 63%. Thirty (
CONCLUSION CONCLUSIONS
Randomized control trial of 30% or 60% oxygen at the initiation of resuscitation of extremely preterm neonates with deferred consent is feasible.
TRIAL REGISTRATION BACKGROUND
Clinicaltrials.gov NCT03706586.
