A systematic review and meta-analysis of pulmonary surfactant combined with budesonide in the treatment of neonatal respiratory distress syndrome.

Background: Neonatal respiratory distress syndrome (NRDS), if caused by a lack of pulmonary surfactant (PS), leads to progressive alveolar collapse. Glucocorticoids have anti-inflammatory and anti-allergic effects and can reduce bronchial and pulmonary edema. This research hopes to systematically evaluate the efficacy and safety of animal-derived PS combined with the glucocorticoid drug budesonide in the treatment of NRDS.
