Effect of prophylactic CPAP in very low birth weight infants in South America

Objective:the objective of this study was to examine the effect of prophylactic continuous positive airway pressure (cpap) on infants born in 25 south american neonatal intensive care units affiliated with the neocosur neonatal network using novel multivariate matching methods.study design:a prospective cohort was constructed of infants with a birth weight 500 to 1500 g born between 2005 and 2011 who clinically were eligible for prophylactic cpap. patients who received prophylactic cpap were matched to those who did not on 23 clinical and sociodemographic variables (n=1268). outcomes were analyzed using the mcnemar’s test.results:infants not receiving prophylactic cpap had higher mortality rates (odds ratio (or)=1.69, 95% confidence interval (ci) 1.17, 2.46), need for any mechanical ventilation (or=1.68, 95% ci 1.33, 2.14) and death or bronchopulmonary dysplasia (bpd) (or=1.47, 95% ci 1.09, 1.98). the benefit of prophylactic cpap varied by birth weight and gender.conclusions:the implementation of this process was associated with a significant improvement in survival and survival free of bpd.
