A Meta-Analysis of the Effects and Safety of Pulmonary Surfactants Combined with Budesonide in Bronchopulmonary Dysplasia

Abstract

Context: The purpose of this analysis was to explore the effects and safety of Pulmonary Surfactants (PS) combined with budesonide in Bronchopulmonary Dysplasia (BPD) by a meta-analysis of Randomized Controlled Trials (RCTs). Evidence acquisition: Literature searches were performed in PubMed, the Cochrane Library, EMBASE, the China Knowledge Network, and the Wanfang database to collect data from RCTs. The primary outcomes were BPD incidence and BPD-related mortality, while the secondary outcomes were BPD-related complications. Bias was evaluated by the Cochrane risk assessment tool. The RevMan 5.3 software was used for the meta-analysis, and the Egger’s test was used for publication bias assessment. Results: A total of 720 subjects were enrolled from six RCTs, including 352 in the experimental group and 368 in the observation group. The BPD incidence (RR = 0. 42, 95% CI [0. 37, 0. 89], P < 0.001) and BPD-related mortality (RR = 0.54, 95% CI [0.38, 0.89], P < 0.05) differed significantly between the two groups. Significant differences were also found in intraventricular hemorrhage, infection/sepsis, Retinopathy of Prematurity (ROP), and Patent Ductus Arteriosus (PDA). There were no significant differences in the incidence of PDA, Neonatal Necrotizing Enterocolitis (NEC), hyperglycemia, and hypertension. Conclusions: The intratracheal instillation of pulmonary surfactants with budesonide can reduce the incidence of BPD and BPD-related mortality with no increased risk of short-term complications.
