To examine the best available evidence for interventions used to manage mild to moderate respiratory distress in late preterm and term infants experiencing delayed respiratory transition.
EMBASE, MEDLINE, Cochrane Review, Joanna Briggs, PubMed, CINAHL, and Google Scholar online databases were searched for articles related to delayed respiratory transition. Reference lists were reviewed to identify additional articles for inclusion.
Randomized, blinded, placebo-controlled, randomized prospective, prospective observational, and retrospective cohort studies published in English-language, peer-reviewed journals between 2007 and August 2017 were reviewed for inclusion. Studies were included if they examined respiratory focused interventions that could potentially prevent admission to the neonatal intensive care unit (NICU) of the term or late preterm infant transitioning to extrauterine life.
The CASP tools were utilized for appraisal of individual studies. Data were extracted from the 5 studies included in this review.
In 4 of the 5 studies, prevention of NICU admission was the primary aim. The observational study observed videos of newborn resuscitations and described the effect of early intervention with continuous positive-airway pressure (CPAP) ventilation on prevention of NICU admission for respiratory distress. One randomized controlled trial used adrenaline injections to prevent development of respiratory distress. The 3 remaining randomized controlled trials used prophylactic CPAP or sustained inflation as a method for preventing development of delayed respiratory transition. Three of the 5 studies focused exclusively on cesarean born infants. Among the interventions studied, early or prophylactic CPAP shows the most promise for prevention of NICU admission in late preterm and term infants with mild to moderate respiratory distress.
The lack of safety and efficacy data for either adrenaline injections or prophylactic CPAP precludes either method for current use in the prevention of respiratory distress for the late preterm or term infant transitioning to extrauterine life. Two randomized trials, both using prophylactic CPAP, had a significant decrease in NICU admissions. Both studies were conducted at a single center and exclusive to infants born by cesarean delivery. A single study using sustained lung inflation showed no significant difference in the need for respiratory support or NICU admission. A single study using adrenaline also showed no benefit to the prevention of respiratory distress related to transition. Further multicenter randomized controlled trials are needed before broad adoption of early or prophylactic CPAP can be recommended.
