Mini-mint ice cubes for early postoperative thirst relief in orthopedic patients undergoing general anesthesia: a randomized controlled trial.
Trial report in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Postoperative thirst affects 70% of surgical patients, causing discomfort and potential complications, especially in orthopedic patients. Current relief strategies remain suboptimal. This trial evaluated the efficacy and safety of mini-mint ice cubes (1 cm³, 20% mint) for early postoperative thirst relief. 282 patients were randomized to three groups: mini-mint ice cubes, room temperature water or absolute fasting. Primary outcome was thirst intensity at PACU discharge, measured by Numerical Rating Scale. Secondary outcomes included PACU stay, oropharyngeal discomfort, satisfaction, 24-hour postoperative quality of recovery (QoR-15), postoperative nausea and vomiting (PONV), delirium and adverse events. Mini-mint group had lower thirst (median [IQR]: 3 [1-5]) vs. water (4 [2-5], median difference: -1, 95% CI: -2 to 0; P = 0.004); vs. absolute fasting (7 [5-9], median difference: -4, 95% CI: -5 to -3; P < 0.001), shorter PACU stay (35 [30-43] min) vs. water (40 [33-45] min, P = 0.014); vs. absolute fasting (40 [35-55] min, P < 0.001), less oropharyngeal discomfort (12.9% vs. absolute fasting 27.2%, P = 0.015), higher satisfaction (4 [4-5]) vs. water (4 [4-5], P = 0.003) and absolute fasting (3 [2-4], P < 0.001), higher QoR-15 (124 [119-130]) vs. water (119 [114-125], P < 0.001) and absolute fasting (117 [111-123], P < 0.001). PONV, delirium, and hypoxemia showed no intergroup differences; cough occurred only in the water group (6.4%). Mini-mint ice cubes safely and effectively alleviate early postoperative thirst in orthopedic patients under general anesthesia, conferring clinically meaningful benefits compared to absolute fasting. Compared to room temperature water, the improvement is modest with uncertain clinical relevance. Clinical trial registration number: ClinicalTrials.gov (ChiCTR2400089335, 6/9/2024).
