Abstract:

Objective

To evaluate the efficacy of airway pressure release ventilation (APRV) in patients with acute respiratory distress syndrome (ARDS).

Methods

The randomized controlled trials (RCTs) about the APRV and conventional mechanical ventilation for the treatment of ARDS patients were retrieved from Cochrane Library, PubMed, Embase, CBM, CNKI, Wangfang databases published up to March 2021. According to the inclusion and exclusion criteria, two researchers shifted the literatures, extracted the data and evaluated the methodological quality of the studies. Meta-analysis was performed using RevMan 5.2 software and Stata 1.4 software.

Results

A total of 11 RCTs were included in this study with 611 patients. The results of meta-analysis showed that the oxygenation index in the APRV group was much higher than that in the control group [mean difference (MD) = 31.70, 95% confidence interval (CI) (3.76, 59.63), Z = 2.22, P = 0.03], while the 28-day mortality was much lower[odds ratio (OR) = 0.55, 95% CI (0.36, 0.84), Z = 2.77, P = 0.006].

Conclusion

For the patients with ARDS, early application of APRV can improve oxygenation and reduce 28-day mortality.
