| 摘 要： | Objective: To assess the efficacy and safety of Chinese medicine injection(CMI) for treating acute lung injury/acute respiratory distress syndrome(ALI/ARDS). Methods: Randomized controlled trials(RCTs) were identified by searching 3 English databases and 4 Chinese databases from their inceptions until February 2019. The Cochrane Handbook was used to evaluate risk of bias in the included studies. Data analysis was conducted using RevMan 5.3.3 software. Results: A total of 19 eligible RCTs involving 1,334 participants was included in this systematic review and meta-analysis. The main meta-analysis showed that CMI combined with conventional therapy(CT) was more effective than CT alone in reducing the acute physiology and chronic health evaluation(APACHE) Ⅱ score [mean difference(MD): –1.74 points, 95% confidence interval(CI): –2.77 to –0.71, I~2=0] and increasing the total effective rate [relative risk(RR): 1.35, 95% CI: 1.17 to 1.56, I~2=37%]. Compared with CT, CMI combined with CT showed improvements in the arterial partial pressure of oxygen(PaO_2, MD: 9.25 mm Hg, 95% CI: 0.87 to 17.63, I~2=98%) and oxygenation index [arterial partial pressure of oxygen(PaO_2)/fraction of inspired oxygen(FiO_2), MD: 50.75 mm Hg, 95% CI: 35.18 to 66.31, I~2=94%]. CMI plus CT was superior to CT in reducing the systemic inflammatory response syndrome(SIRS) score(MD: –0.84 points, 95% CI: –1.26 to –0.42, I~2=65%), length of hospital stay(MD: –4.22 days, 95% CI: –6.49 to –1.95, I~2=92%), and duration of mechanical ventilation(MD: –2.94 days, 95% CI: –4.68 to –1.21, I~2=89%). Only 1 study reported adverse events. Conclusions: CMI as an adjuvant therapy showed great potential benefits for the treatment of ALI/ARDS. However, we could not make a definite conclusion due to low quality of included studies and uncertain security. Future studies should focus on improving research design, especially in blindness and placebo. The reporting of adverse events was also needed.
