Abstract

Background

There is increased use of early nasal continuous positive airway pressure (NCPAP) to manage respiratory distress in preterm infants but optimal methods and factors associated with successful wean are not well defined. A systematic review was performed to define the corrected gestational age (CGA), weight to wean NCPAP and the methods associated with successful weaning of the NCPAP among preterm infants, along with factors affecting it.

Methods

Searches were made of PubMed using the keywords-NCPAP, CPAP, weaning, withdrawal, preterm, and infants from its inception to January 1st, 2014, for studies in all languages but limited to humans. Previous reviews (including cross references) were also searched. We included all randomized and quasi-randomized controlled trials where preterm neonates were randomized to different NCPAP weaning strategies. Details of CGA, weight and methods used for weaning NCPAP were extracted along with factors which affect its withdrawal.

Results

Seven studies met the search criteria. The successful wean was at 32 to 33 weeks CGA and at 1600 g. Three different methods were used for weaning were sudden, gradual pressure wean and gradual graded time off wean. Criteria for readiness, success and failure to wean were defined. Factors affecting successful weaning were intubation, anemia, infection and gastro-esophageal reflux.

Conclusions

The successful wean was at 32 to 33 weeks CGA and 1600 g. Criteria for readiness, success and failure to wean are well defined. Sudden weaning may be associated with a shorter weaning time. Future trials are needed comparing weaning methods using defined criteria for readiness and success of NCPAP wean and stratify the results by gestational age and birth weight.
