Objective:To evaluate the effectiveness and safety of different interventions to prevent etomidate-induced myoclonus based on Bayesian network Meta-analysis, aiming at reducing and improving the occurrence of etomidate myoclonus clinically.Methods:Pubmed, Embase, the Cochrane Central Register of Controlled Trials(CENTRAL), China National Knowledge Infrastructure(CNKI), Wanfang Data Knowledge Service Platform, VIP Chinese Journal Service Platform and Chinese Biomedical Literature Database(CBM) were used to retrieve randomized controlled trials(RCTs) published in Chinese and English on different interventions for the prevention of etomidate-induced myoclonus from the establishment of the database to August 2024. Revman 5.4 and Stata 18.0 software were used for Bayesian network meta-analysis. The relative risk(RR) and corresponding 95% confidence interval(CI) were used to evaluate the efficacy and safety of different interventions for etomidate myoclonus. Results:A total of 37 articles with 3 078 subjects were included, involving 8 interventions: midazolam, butorphanol, dezocine, dexmedetomidine, remifentanil, sufentanil, fentanyl and placebo. The results of network meta-analysis showed that sufentanil(RR=0.10, 95%CI 0.04-0.27), remifentanil(RR=0.14, 95%CI 0.08-0.24), dezocine(RR=0.18, 95%CI 0.09-0.34), butorphanol(RR=0.19, 95%CI 0.04-0.27), dexmedetomidine(RR=0.20, 95%CI 0.12-0.33), midazolam(RR=0.22, 95%CI 0.12-0.41) were better than placebo(all P<0.05). Sufentanil(RR=0.22, 95%CI 0.06-0.84) and remifentanil(RR=0.32, 95%CI 0.12-0.89) had a better preventive effect than fentanyl(both P<0.05). SUCRA probability ranking results showed that sufentanil(89.0%)>remifentanil(78.3%)>dezocine(60.4%)>butorphanol(56.9%)>dexmedetomidine(51.1%)>midazolam(45.7%)>fentanyl(18.0%)>placebo(0.5%). The publication bias analysis of the included studies showed that there was a certain asymmetry in the outcome indicators, suggesting that there was a certain risk of publication bias. Conclusion:Through network Meta-analysis integrating direct or indirect evidence between different drugs, it is found that opioids can effectively reduce the incidence of etomidate-induced myoclonus, among which sufentanil has the best effect, followed by remifentanil. However, attention should be paid to the occurrence of complications such as chest wall rigidity and slow heart rate when using opioid pretreatment. |
