Effect of airway management method on hypothermia in patients undergoing laparoscopic gynecologic surgery: tracheal intubation, supreme laryngeal mask, and i-gel laryngeal mask.

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
objectiveThis study aimed to assess the association between different airway management methods and perioperative hypothermia in gynecologic laparoscopic surgery.
methodsThis single-center prospective cohort observational study included patients who underwent gynecologic laparoscopic surgery between September 2022 and February 2023. A total of 531 patients scheduled for non-emergent surgery were recruited and randomly assigned to the tracheal intubation group (T group) (n = 153), supreme laryngeal mask group (L group) (n = 156), or i-gel laryngeal mask group (i group) (n = 151). Following anesthesia induction, the primary outcome was the incidence of intraoperative hypothermia at the end of surgery. Secondary outcomes included final core body temperature, incidence of nosebleeds, flushing and fluid administration, urine output, and other relevant parameters. Multivariate logistic regression analyses were conducted to identify risk factors associated with hypothermia.
resultsThe incidence of postoperative hypothermia in the L and i groups was significantly lower than of the T group (P < 0.05). At the end of surgery, the core body temperature in the T group was also lower than in the L and i groups (P < 0.05). Extubation and recovery times differed significantly among the three groups, with the T group showing longer durations compared to the two laryngeal mask groups (P < 0.05). During postoperative follow-up, the incidence of nasal bleeding in the T group was higher than of the other two groups (P < 0.05). No significant differences were observed in the incidence of other postoperative complications (P > 0.05).
conclusionIn patients undergoing gynecologic laparoscopic surgery, tracheal intubation is associated with a higher likelihood of perioperative hypothermia compared to laryngeal mask use.
