Effects of different inflatable heater temperature settings on early postoperative recovery after hysteroscopic...

To investigate the effect of perioperative temperature settings of an inflatable warming device on postoperative recovery quality in patients undergoing hysteroscopic myomectomy, this randomized controlled trial enrolled 258 patients receiving laryngeal mask general anesthesia at Xuzhou Central Hospital, China, between March 2022 and August 2024. Patients were allocated to perioperative temperature management with an inflatable warming device set to 38 °C (Group L, n = 129) or 43 °C (Group H, n = 129). A total of 211 patients were included in the final analysis after accounting for exclusions. At 24 h postoperatively, the QoR-40 score was significantly higher in Group H compared to Group L (P < 0.05). At baseline (T0), no significant differences in core body temperature, mean arterial pressure (MAP), or heart rate (HR) were observed between groups (P > 0.05). From T1 to T6, Group H exhibited higher and more stable core body temperature, MAP, and HR compared to Group L (P < 0.05). There were no statistically significant differences in QoR-40 scores at 48 h (P > 0.05) or in the incidence of postoperative restlessness, chills, and infection between the two groups. Compared to 38 °C, the perioperative application of a 43 °C inflatable warming device improved early postoperative recovery quality at 24 h in hysteroscopic myomectomy patients without increasing complication risks.
