Inadvertent intraoperative hypothermia is frequent during open surgeries; however, few studies on hypothermia during laparoscopic abdominal surgery have been reported. We aimed to investigate the incidence and risk factors for hypothermia in patients undergoing laparoscopic abdominal surgery.
This single-center prospective cohort observational study involved patients undergoing laparoscopic surgery between October 2018 and June 2019. Data on core body temperature and potential variables were collected. A multivariate logistic regression analysis was performed to identify the risk factors associated with hypothermia. A Cox regression analysis was used to verify the sensitivity of the results.
In total, 690 patients were included in the analysis, of whom 200 (29.0%, 95% CI: 26%-32%) had a core temperature < 36°C. The core temperature decreased over time, and the incident hypothermia increased gradually. In the multivariate logistic regression analysis, age (OR = 1.017, 95% CI: 1.000-1.034, P = 0.050), BMI (OR = 0.938, 95% CI: 0.880-1.000; P = 0.049), baseline body temperature (OR = 0.025, 95% CI: 0.010-0.060; P < 0.001), volume of irrigation fluids (OR = 1.001, 95% CI: 1.000-1.001, P = 0.001), volume of urine (OR = 1.001, 95% CI: 1.000-1.003, P = 0.070), and duration of surgery (OR = 1.010, 95% CI: 1.006-1.015, P < 0.001) were significantly associated with hypothermia. In the Cox analysis, variables in the final model were age, BMI, baseline body temperature, volume of irrigation fluids, blood loss, and duration of surgery.
Inadvertent intraoperative hypothermia is evident in patients undergoing laparoscopic surgeries. Age, BMI, baseline body temperature, volume of irrigation fluids, and duration of surgery are significantly associated with intraoperative hypothermia.
在开放性手术中，术中意外低体温很常见；然而，关于腹腔镜腹部手术中低体温的研究较少。我们旨在研究腹腔镜腹部手术患者中低体温的发生率和危险因素。
这是一项单中心前瞻性队列观察研究，纳入了 2018 年 10 月至 2019 年 6 月期间接受腹腔镜手术的患者。收集核心体温和潜在变量的数据。采用多变量逻辑回归分析确定与低体温相关的危险因素。采用 Cox 回归分析验证结果的敏感性。
共纳入 690 例患者，其中 200 例（29.0%，95%CI：26%-32%）核心体温<36°C。核心体温随时间下降，发生低体温的比例逐渐增加。多变量逻辑回归分析显示，年龄（OR=1.017，95%CI：1.000-1.034，P=0.050）、BMI（OR=0.938，95%CI：0.880-1.000；P=0.049）、基础体温（OR=0.025，95%CI：0.010-0.060；P<0.001）、灌洗液量（OR=1.001，95%CI：1.000-1.001，P=0.001）、尿量（OR=1.001，95%CI：1.000-1.003，P=0.070）和手术时间（OR=1.010，95%CI：1.006-1.015，P<0.001）与低体温显著相关。Cox 分析显示，最终模型中的变量为年龄、BMI、基础体温、灌洗液量、失血量和手术时间。
腹腔镜手术患者术中发生意外低体温。年龄、BMI、基础体温、灌洗液量和手术时间与术中低体温显著相关。
