  • Surfactant replacement therapy on ECMO does not improve outcome in neonates with congenital diaphragmatic hernia JOURNAL OF PEDIATRIC SURGERY Colby, C. E. 2004; 39 (11): 1632-1637

    Abstract:

    Respiratory failure in neonates with congenital diaphragmatic hernia (CDH) may in part be caused by a primary or secondary surfactant deficiency. Knowledge of the optimal approach to surfactant replacement in neonates with CDH and respiratory failure is limited. The aim of this study was to determine if surfactant replacement on extracorporeal membrane oxygenation (ECMO) results in improved outcomes in neonates > or =35 weeks' gestation with unrepaired CDH.Using the CDH Study Group Registry, the authors identified 448 neonates with CDH who were > or =35 weeks' gestation, had no major anomalies, were treated with ECMO within the first 7 days of life, and underwent repair on or after ECMO therapy. Patients in 2 groups were compared: group 1 (- Surf, n = 334) consisted of patients who received no surfactant and group 2 (+ Surf, n = 114) consisted of patients who received at least 1 dose of surfactant while on ECMO. An analysis of all patients in both groups was performed. Additionally, subgroup analyses stratified by gestational age were performed for patients 351/7 to 366/7 weeks' gestation and for patients > or =37 weeks' gestation. Primary end-points for the study were survival and length of ECMO run. Secondary end-points were length of intubation, need for supplemental oxygen at 30 days of life, and at discharge to home. Demographic, clinical, and outcome variables were examined using Fisher's Exact tests for categorical variables and using unpaired t tests for continuous variables. Odds ratios were calculated for categorical end-point variables.Demographic and clinical variables were similar between groups. Analyses of aggregate data showed no significant differences between groups in length of ECMO run, survival, number of days intubated, and percent of patients requiring supplemental oxygen at 30 days or discharge. Subgroup stratification by gestational age did not show significant differences between groups in any of the outcome variables.The data from this study suggest that surfactant replacement on ECMO for neonates with congenital diaphragmatic hernia does not provide significant benefit in the infant's clinical course with respect to survival, length of ECMO course, length of intubation, or subsequent need for supplemental oxygen.
