Surfactant in spontaneous breathing with nCPAP: neurodevelopmental outcome at early school age of infants ≤ 27 weeks

Abstract

Aim: In 2001, we implemented the 'surfactant without intubation' (SWI) method to administer surfactant during spontaneous breathing with nasal continuous positive airway pressure in preterm infants. To determine whether application of the SWI method in infants born at ≤ 27 weeks gestational age influences early school age outcome.

Methods: A historical control cohort was compared to an interventional cohort, when the SWI method had become part of primary respiratory support. According to the overall results of psychometric and neurological examinations, children were classified as showing no functional impairment, minor or major impairments.

Results: Out of 79 surviving children, 54 (68%, two children not completely classifiable) were assessed at a median age of 6 5/12 years [25 (32%) lost to follow-up]. Thirteen of 31 (42%, interventional cohort) vs. 8 of 21 (38%, control cohort) children had no functional impairment, 16 (52%) vs. 9 (43%) showed minor, and 2 (7%) vs. 4 (19%) major impairments.

Conclusion: There was no statistically significant difference regarding neurodevelopmental school age outcome in children treated after implementing the SWI procedure, even though surviving infants had been more immature and survival rates had increased.
