Background:
Midazolam has some potential in pain control of patients undergoing knee arthroscopy. However, the results remain controversial. We conduct a systematic review and meta-analysis to explore the effect of midazolam on pain control after knee arthroscopy.
Methods:
PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases are systematically searched. Randomized controlled trials (RCTs) assessing the effect of midazolam on pain management after knee arthroscopy are included. Two investigators have independently searched articles, extracted the data, and assessed the quality of the included studies. This meta-analysis is performed using the random-effect model.
Results:
Six RCTs are included in this meta-analysis. Compared with control intervention after knee arthroscopy, midazolam intervention can significantly reduce the pain scores (standard mean difference (Std. MD) = - 3.70; 95% confidence interval (CI) = - 6.81 to - 0.60; P = 0.02), the number of patients requiring analgesics (risk ratio (RR) = 0.66; 95% CI = 0.49 to 0.88; P = 0.005), and analgesic consumption (Std. MD = -1.62; 95% CI = - 3.04 to - 0.19; P = 0.03), as well as increase the time to first analgesic requirement (Std. MD = 1.58; 95% CI = 0.17 to 2.99; P = 0.03). In addition, midazolam intervention results in no increase in adverse events following knee arthroscopy (RR = 0.74; 95% CI = 0.18 to 2.98; P = 0.67).
Conclusions:
Midazolam intervention is revealed to substantially reduce the pain scores, the number of patients requiring analgesics, and analgesic consumption, as well as improve the time to first analgesic requirement after knee arthroscopy.
