Abstract：Objective To analyze the risk factors and intervention measures of hypothermia during laparoscopic hysterectomy under general anesthesia. Methods A total of 408 patients who underwent laparoscopic hysterectomy under general anesthesia in the First Affiliated Hospital of Nanjing Medical University from January 2022 to January 2023 were retrospectively included. According to whether there was hypothermia during the operation,they were divided into two groups：51 patients of the group with intraoperative hypothermia and 357 patients of the group without intraoperative hypothermia. The general data of patients were counted,and the single factor analysis of intraoperative hypothermia in patients undergoing laparoscopic hysterectomy under general anesthesia was carried out. The related factors affecting the occurrence of intraoperative hypothermia in patients undergoing laparoscopic hysterectomy under general anesthesia were analyzed by multivariate Logistic regression. Results The results of univariate analysis showed that the age in the group with intraoperative hypothermia was higher than that in the group without intraoperative hypothermia,and the anesthesia time and operation time were longer than those in the group without intraoperative hypothermia,while the amount of fluid replacement,carbon dioxide consumption and bleeding volume were higher than those in the group without intraoperative hypothermia,with statistical significance. Multivariate Logistic analysis showed that anesthesia time ≥90 min,operation time ≥120 min,fluid infusion ≥2 000 mL,carbon dioxide dosage ≥150 L,and bleeding volume ≥100 mL were all risk factors for intraoperative hypothermia in patients undergoing laparoscopic hysterectomy under general anesthesia. Conclusion Risk factors that affected the occurrence of intraoperative hypothermia in patients undergoing laparoscopic hysterectomy under general anesthesia included anesthesia time ≥90 min,operation time ≥120 min,fluid infusion≥2 000 mL,carbon dioxide dosage≥150 L,and bleeding volume≥100 mL. Therefore,targeted intervention measures could be taken for patients undergoing laparoscopic hysterectomy under general anesthesia to reduce the risk of intraoperative hypothermia.
