Abstract
BACKGROUND: Patients with cirrhosis frequently require sedation for elective endoscopic procedures. Several sedation protocols are available, but choosing an appropriate sedative in patients with cirrhosis is challenging. AIM: To conduct a systematic review and meta-analysis to compare propofol and midazolam for sedation in patients with cirrhosis during elective endoscopic procedures in an attempt to understand the best approach. METHODS: This systematic review and meta-analysis was conducted using the PRISMA guidelines. Electronic searches were performed using MEDLINE, EMBASE, Central Cochrane, LILACS databases. Only randomized control trials (RCTs) were included. The outcomes studied were procedure time, recovery time, discharge time, and adverse events (bradycardia, hypotension, and hypoxemia). The risk of bias assessment was performed using the Revised Cochrane Risk-of-Bias tool for randomized trials (RoB-2). Quality of evidence was evaluated by GRADEpro. The meta-analysis was performed using Review Manager. RESULTS: = 0.93). Five studies had low risk of bias, two demonstrated some concerns, and one presented high risk. The quality of the evidence was very low for procedure time, recovery time, and adverse events; while low for discharge time. CONCLUSION: This systematic review and meta-analysis based on RCTs show that propofol has shorter recovery and patient discharge time as compared to midazolam with a similar rate of adverse events. These results suggest that propofol should be the preferred agent for sedation in patients with cirrhosis.
