The role of non‐invasive positive pressure ventilation ( NIPPV ) in acute lung injury ( ALI )/acute respiratory distress syndrome ( ARDS ) is controversial. The aim of this study was to investigate whether NIPPV could prevent endotracheal intubation and decrease mortality rate in patients with ALI / ARDS . Randomized controlled trials ( RCT ) which reported endotracheal intubation and mortality rate in patients with ALI / ARDS treated by NIPPV were identified in P ubmed, M edline, E mbase, C entral Cochrane Controlled Trials Register, Chinese National Knowledge Infrastructure, reference lists and by manual searches. Fixed‐ and random‐effects models were used to calculate pooled relative risks. This meta‐analysis included six RCT involving 227 patients. The results showed that endotracheal intubation rate was lower in NIPPV (95% confidence interval ( CI ): 0.44–0.80, z = 3.44, P = 0.0006), but no significant difference was found either in intensive care unit ( ICU ) mortality (95% CI : 0.45–1.07, z = 1.65, P = 0.10) or in hospital mortality (95% CI : 0.17–1.58, z = 1.16, P = 0.25). Only two studies discussed the aetiology of ALI / ARDS as pulmonary or extra‐pulmonary, and neither showed statistical heterogeneity ( I 2 = 0%, χ 2 = 0.31, P = 0.58), nor a significant difference in endotracheal intubation rate (95% CI : 0.35–9.08, z = 0.69, P = 0.49). In conclusion, the early use of NIPPV can decrease the endotracheal intubation rate in patients with ALI / ARDS , but does not change the mortality of these patients.
