Abstract

Background NCPAP facilitates successful extubation. It is unclear whether HFNC are as effective as NCPAP in preventing extubation failure. In addition to an alternative modality of respiratory support HFNC may result in less nasal trauma than NCPAP.

Methods 132 preterm ventilated infants were randomised and stratified by gestation(< 28 vs 28–32 weeks). Primary outcome was extubation failure defined by a composite of 3 pre-specified failure criteria in the 7 days post-extubation. Individual failure criteria were not mutually exclusive and are defined; Apnoea, > 6 episodes in 6 hours or 1 requiring IPPV, Acidosis, pH< 7.25 & pCO2>66mmHg, and >15% increase in FiO2 from extubation. A nasal trauma score was adapted from Kaufman [E-PAS 2007:61390].

Abstract 137 Table 1

Conclusions Rates of extubation failure were not significantly different between the groups. HFNC resulted in significantly less nasal trauma than NCPAP. This benefit may need to be considered in post-extubation respiratory support for preterm infants.
