Comparison of the effects of remimazolam and inhalational anesthesia on postoperative recovery in patients undergoing general anesthesia: a systematic review and meta-analysis of randomized controlled trials.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRemimazolam is an ultra-short-acting benzodiazepine characterized by rapid onset and recovery with minimal accumulation after continuous infusion. This systematic review and meta-analysis aimed to evaluate whether remimazolam use results in better postoperative recovery as compared to inhalational anesthetics.
methodsDatabases including MEDLINE, EMBASE, CENTRAL, Web of Science, Google Scholar, and Scopus were searched up to August 2024. Randomized controlled trials (RCTs) in adult patients comparing remimazolam with volatile agents were included. The primary outcome was incidence of postoperative nausea and vomiting (PONV) at 24 h. Secondary outcomes included use of rescue antiemetics and analgesics, pain scores, intraoperative hypotension, and other postoperative recovery parameters. Trial sequential analysis (TSA) was performed to validate the robustness of the primary outcome.
resultsTwelve RCTs involving 853 patients were analyzed. Remimazolam significantly reduced the incidence of PONV (relative risk [RR] 0.51; 95% confidence interval [CI] 0.27-0.96; I² = 43%; P = 0.04) and need for rescue antiemetics (RR 0.30; 95% CI 0.10-0.89; I² = 0%; P = 0.03) compared to inhalational agents. No significant differences were found in postoperative pain scores (standardized mean difference -0.17; P = 0.11) or analgesic requirement (RR 0.95; P = 0.82). Remimazolam was associated with a significantly lower incidence of intraoperative hypotension (RR 0.58; P = 0.01). Time to extubation, sedation scores, and post-anesthesia care unit stay were comparable. TSA confirmed that the required information size for the primary outcome was reached, indicating statistical conclusiveness.
conclusionsRemimazolam use is associated with significantly reduced PONV, rescue antiemetic use, and intraoperative hypotension compared to inhalational agents. TSA confirms the robustness of these findings.
