Outcomes of preterm infants receiving positive pressure support at term corrected gestation

Abstract

Aim To establish the mortality rate to hospital discharge of very preterm infants who remain on positive pressure support (PPS) at term corrected gestation and describe factors that are associated with increased mortality. Methods Infants born <30 weeks' gestation between 1 January 2001 and 31 December 2009 who were receiving PPS at 40 weeks' postmenstrual age (PMA) were identified from our database, and their medical records reviewed. The fraction of inspired oxygen (FiO2), mean airway pressure and partial pressure of carbon dioxide (PaCO2) at 40 weeks' PMA were recorded. Receiver operating characteristic curves for mortality before discharge were generated. Results One thousand three hundr..
