Nasal intermittent positive pressure ventilation during less invasive surfactant administration in preterm infants: An open‐label randomized controlled study

Le résumé fourni par la source

Abstract Introduction Approximately half of very preterm infants with respiratory distress syndrome (RDS) fail treatment with nasal continuous positive airway pressure (NCPAP) and need mechanical ventilation (MV). Objectives Our aim with this study was to evaluate if nasal intermittent positive pressure ventilation (NIPPV) during less invasive surfactant treatment (LISA) can improve respiratory outcome compared with NCPAP. Materials and Methods We carried out an open‐label randomized controlled trial at tertiary neonatal intensive care units in which infants with RDS born at 25+0−31+6 weeks of gestation between December 1, 2020 and October 31, 2022 were supported with NCPAP before and after surfactant administration and received NIPPV or NCPAP during LISA. The primary endpoint was the need for a second dose of surfactant or MV in the first 72 h of life. Other endpoints were need and duration of invasive and noninvasive respiratory supports, changes in SpO2/FiO2 ratio after LISA, and adverse effect rate. Results We enrolled 101 infants in the NIPPV group and 99 in the NCPAP group. The unadjusted odds ratio for the composite primary outcome was 0.873 (95% confidence interval: 0.456–1.671; p = .681). We found that the SpO2/FiO2 ratio was transiently higher in the LISA plus NIPPV than in the LISA plus NCPAP group, while adverse effects of LISA had similar occurrence in the two arms. Conclusions The application of NIPPV or NCPAP during LISA in very preterm infants supported with NCPAP before and after surfactant administration had similar effects on the short‐term respiratory outcome and are both safe. Our study does not support the use of NIPPV during LISA.
