1 · What the graph read from it

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.

2 · The registry

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

backgroundIntraoperative hypotension may result in a higher incidence of postoperative myocardial injury, acute kidney injury, and stroke. Notably, more than half of intraoperative hypotension cases occur immediately after induction of general anesthesia. Although intraoperative hypotension has multiple causes, post-induction hypotension is primarily due to the effects of anesthetic drugs. Propofol is the most widely used agent for anesthesia induction. However, propofol can induce hemodynamic instability, potentially leading to adverse postoperative outcomes. Remimazolam, a novel ultra-short-acting intravenous sedative-hypnotic, may promote stable hemodynamics. Studies have reported that remimazolam is associated with less hypotension compared to propofol. Therefore, this study aims to compare the hemodynamic effects of remimazolam and propofol during anesthesia induction in patients undergoing video-assisted thoracoscopic surgery.

methodsThis is a prospective, multicenter randomized controlled trial. A total of 172 patients aged 45 to 65 years undergoing video-assisted thoracoscopic surgery will be randomly allocated to receive remimazolam or propofol during anesthetic induction. The primary outcome is the incidence of hypotension occurring within 20 min after anesthesia induction. Hypotension is defined as systolic blood pressure (SBP) of less than 90 mmHg, or a reduction of more than 30% in SBP from baseline, or the administration of vasoactive medication. Secondary outcomes include the rate of successful sedation, time to successful sedation, coughing during the induction period, postoperative delirium within 7 days after surgery, and postoperative in-hospital mortality. DISCUSSION: To date, remimazolam has rarely been used for anesthesia induction in video-assisted thoracoscopic surgery. This study will provide important information on hemodynamic stability and anesthesia efficacy of remimazolam in this surgical setting.
