Abstract
BACKGROUND

Remimazolam is a new benzodiazepine used for procedural sedation and general anesthesia. Several studies have used remimazolam for bendable bronchoscopy.

AIM

To assess the safety and efficacy of remimazolam for sedation in patients undergoing bendable bronchoscopy by performing a meta-analysis of randomized controlled trials (RCTs).

METHODS

We searched the EMBASE, PubMed, Cochrane Library, and Web of Science databases for RCTs on bendable bronchoscopic procedural sedation with remimazolam vs conventional sedatives (CS).

RESULTS

Five studies with 1080 cases were included. Remimazolam had the same sedation success rate compared with CS [relative risk (RR): 1.35, 95%CI: 0.60-3.05, P = 0.474, I2 = 99.6%]. However, remimazolam was associated with a lower incidence of hypotension (RR: 0.61; 95%CI: 0.40-0.95, P = 0.027; I2 = 65.1%) and a lower incidence of respiratory depression (RR: 0.50, 95%CI: 0.33-0.77, P = 0.002, I2 = 42.3%). A subgroup analysis showed a higher success rate of sedation with remimazolam than midazolam (RR: 2.45, 95%CI: 1.76-3.42, P < 0.001). Compared with propofol, the incidence of hypotension (RR: 0.45, 95%CI: 0.32-0.64, P < 0.001, I2 = 0.0%), respiratory depression (RR: 0.48, 95%CI: 0.30-0.76, P = 0.002, I2 = 78.4%), hypoxemia (RR: 0.36, 95%CI: 0.15-0.87, P = 0.023), and injection pain (RR: 0.04, 95%CI: 0.01-0.28, P = 0.001) were lower.

CONCLUSION

Remimazolam is safe and effective during bronchoscopy. The sedation success rate was similar to that in the CS group. However, remimazolam has a higher safety profile, with fewer inhibitory effects on respiration and circulation.

Core Tip: We searched the databases of EMBASE, PubMed, Cochrane Library, and the Web of Science for randomized controlled trials of bendable bronchoscopic procedural sedation with remimazolam vs conventional sedatives (CS) from the time the database was created until August 2023. STATA 15.1 software was applied to data analyses. Five studies with 1080 cases were included. We finally came to the conclusion: Remimazolam is safe and effective for cases with bronchoscopy. Its sedation success rate is similar to CS. However, remimazolam has a higher safety profile with less inhibitory effects on respiration and circulation.
