Evaluation of the analgesic efficacy of dinalbuphine sebacate in transoral robotic surgery for obstructive sleep apnea-hypopnea syndrome: a single-center retrospective cohort study.

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
Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a chronic disorder with significant comorbidities. Transoral robotic surgery (TORS) combined with uvulopalatopharyngoplasty (UPPP) is an established treatment, but postoperative pain management remains challenging. This study evaluates the efficacy of dinalbuphine sebacate (DNS), an extended-release analgesic, in reducing opioid use and managing postoperative pain in TORS UPPP patients. This retrospective cohort included consecutive TORS-UPPP patients from 1 January 2020 to 30 June 2024; the database was locked on 30 June 2024 prior to analysis. The patients were divided into a DNS group (n = 96) and a conventional analgesia (CA) group (n = 42). The DNS group received a 150 mg intramuscular injection after anesthetic induction and after the surgery. Analgesic consumption, opioid usage, and pain scores were evaluated from the day of surgery (POD0) to two days postoperatively (POD2), as well as opioid prescriptions at discharge and during the first follow-up. The DNS group exhibited a significantly lower percentage of opioid use during POD0-POD2 (30.21% vs. 54.76%, p < 0.001) and a reduced oral morphine equivalent dose (15.31 ± 36.68 mg vs. 56.79 ± 85.83 mg, p = 0.001). Opioid prescriptions at discharge (68.75% vs. 88.10%, p = 0.016) and at the first follow-up (13.54% vs. 52.38%, p < 0.001) were also lower in the DNS group, with comparable analgesic effects. DNS effectively reduces postoperative opioid consumption and prescription in TORS UPPP patients without significant adverse effects. These findings support the integration of DNS into multimodal analgesia protocols for OSAHS surgery, substantially reduced inpatient and post-discharge opioid use (NNT ≈ 3-5) with small, likely non-clinically important differences in pain scores and no significant safety signal, supporting its clinical relevance in OSAHS surgical programs. Warranting further multicenter validation.
