The purpose of this study was to analyze the impact of neonatal care practices on the efficacy of exogenous human surfactant. Two hundred newborns (gestational age 24.0 to 29.9 weeks, lecithin-sphingomyelin ratio less than 2 or absent phosphatidylglycerol, and requirement of mechanical ventilation at birth) participated in a randomized bicenter trial of human surfactant substitution. In only one of the two sites (site 2) surfactant substitution decreased the severity of respiratory failure and increased neonatal survival without bronchopulmonary dysplasia. For analysis of three-way association, continuous variables describing patient characteristics and treatment were dichotomized at the median. The following variables were significantly associated with good outcome in site 1 and 2 and with surfactant substitution in site 2: low oxygen requirement during first three neonatal days, low mean airway pressure during second and third day, low PaCO2 during first two neonatal days, and no ligation of ductus arteriosus. Low fluid intake during the first three days and low colloid intake during the first two days of life were associated with good outcome in both sites. The ratio between mean airway pressure and the oxygen requirement was higher in site 2 than in site 1 during the first day of life. Fluid intake and ventilatory management may influence the efficacy of exogenous surfactant.
