Surfactant without Endotracheal Tube Intubation (SurE) versus Intubation-Surfactant-Extubation (InSurE) in Neonatal Respiratory Distress Syndrome: A Systematic Review and Meta-Analysis

Abstract

Neonatal respiratory distress syndrome (NRDS) is generally treated with surfactant by intubation-surfactant-extubation (InSurE) technique, an invasive method of surfactant administration. Surfactant without endotracheal tube intubation (SurE) is a noninvasive technique that avoids intubation and has been found to have improved the delivery of exogenous surfactants, thereby decreasing lung damage in neonates. This systematic review aimed to provide insights into the efficacy of SurE over InSurE in neonates who received respiratory support and to evaluate the progression and onset of concurrent diseases after treatment. The CENTRAL, PubMed, and Embase databases were searched for data collection. In all, 21 research articles were eligible, comprising 19,976 study participants. The data showed a significant reduction in the composite outcome of stage 2 necrotizing enterocolitis, bronchopulmonary dysplasia, and onset of hemodynamically significant patent ductus arteriosus when treated with SurE. The trend towards lower pneumothorax rates with SurE was also evident. These findings were robust due to the sensitivity analyses performed. There were no differences in the outcome of death or rates of other neonatal morbidities. Overall, SurE was identified as a better substitute for InSurE to treat neonates with RDS.
