Effect of improving sleep quality the night before surgery with zolpidem on postoperative gastrointestinal function in patients undergoing laparoscopic partial colorectal resection: a randomized, double-blind, controlled trial.
Trial report in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundSleep is one of the basic physiological needs of human beings. Preoperative sleep disorders are associated with poor prognosis in surgical patients, and sleep disorders have been shown to be one of the risk factors for gastrointestinal dysfunction. However, there are now few studies to investigate whether improving preoperative sleep disorders can promote the recovery of postoperative gastrointestinal function. This study aimed to investigate the effects and significance of improving preoperative sleep quality with zolpidem on postoperative gastrointestinal function.
methodsIn this prospective, randomized, double-blind clinical trial, 76 patients undergoing elective laparoscopic partial colorectal resection and with a Pittsburgh Sleep Quality Index (PSQI) score > 5, were randomly divided into two groups. The zolpidem group (Group Z, n = 38) was given a capsule containing 10 mg of zolpidem the night before the operation, and the control group (Group C, n = 38) was given an empty capsule the night before the operation. Follow-up visits were performed on the 1st, 3rd, and 7th postoperative days, respectively. The primary outcome of this study was the I-FEED (Intake, Feeling nauseated, Emesis, Physical Exam, and Duration of symptoms) score on the third postoperative day (POD3). Secondary outcomes included time to postoperative first flatus, first feces, and first food intake (semi-liquid diet), I-FEED scores, visual analog scores (VAS) during coughing and at rest, times of patient-controlled intravenous analgesia (PCIA) effective presses, sufentanil dosage, number of remedial analgesia in the 24-hour postoperative period, and changes in inflammatory markers (TNF-α).
resultsCompared with Group C, Group Z had a lower I-FEED score on POD1 (P < 0.05) and shorter time to first flatus and first food intake (P < 0.05); there were significant differences between the two groups in VAS scores during coughing and at rest on POD1, VAS score during coughing on POD3, times of PCIA effective presses and sufentanil dosage in the 24-hour postoperative period, and patient satisfaction (P < 0.05).
conclusionFor patients with sleep disorders, the use of zolpidem to improve sleep the night before surgery is beneficial in partially improving postoperative gastrointestinal function, relieving postoperative pain, and increasing patient satisfaction.
