Objective To review the effects of pulmonary surfactant in adult patients with acute lung injury ( ALI) /acute respiratory distress syndrome ( ARDS) .
Methods Randomized controlled trials ( RCTs) were recruited from PubMed ( 1966.1-2011.3) , ISI Web of Knowledge ( all the years) and Wanfang Database ( 1982-2011) . Related published data and attached references were hand searched. All the RCTs about pulmonary surfactant for the adult patients with ALI/ARDS were included, then a meta-analysis was performed.
Results Eight eligible trials were enrolled. Pooled analysis showed that treatment with pulmonary surfactant was not associated with reduction in 28 or 30-day mortality compared with the control group [ OR 1.05, 95% CI ( 0.90, 1.22 ) , P = 0.55] , neither did subgroup analysis in the pneumoia/ aspiration, sepsis, and trauma/ surgery induced ALI/ARDS patients. Three RCTs showed the oxygenation was significantly improved in adult ALI/ARDS patients receiving pulmonary surfactant compared with the control group( P lt;0.05) . Shorter mechanical ventilation days was shown in the ALI/ARDS patients receiving pulmonary surfactant in one RCT(P lt;0.05) .
Conclusions Meta-analysis showed pulmonary surfactant did not reduce the 28 or 30-day mortality of adult patients with ALI/ARDS, however, improved the oxygenation. Pulmonary surfactant can be considered a therapy in ALI/ARDS.
