This study aimed to investigate the impact of intraoperative hypothermia on the recovery period of anesthesia in elderly patients undergoing abdominal surgery.
A prospective observational study was conducted based on inclusion and exclusion criteria. A total of 384 elderly patients undergoing abdominal surgery under general anesthesia were enrolled in a grade A tertiary hospital in Chengdu, Sichuan Province from October 2021 and October 2022. After anesthesia induction, inflatable warming blankets were routinely used for active heat preservation, and nasopharyngeal temperature was monitored to observe the occurrence of intraoperative hypothermia. Patients were divided into hypothermia group and nonhypothermia group according to whether hypothermia occurred during the operation. Anesthesia recovery time and the incidence of adverse events or unwanted events during anesthesia recovery between the two groups were compared.
The numbers (percentage) of 384 patients who underwent abdominal surgery developed intraoperative hypothermia occurred in 240 (62.5%) patients, all of whom had mild hypothermia. There were statistically significant differences between mild hypothermia after active warming and nonhypothermia in the occurrence of shivering (χ2 = 5.197, P = 0.023) and anesthesia recovery time (Z = -2.269, P = 0.02) in elderly patients undergoing abdominal surgery during anesthesia recovery, and there were no statistically significant differences in hypoxemia, nausea or vomiting, hypertension, hypokalemia, hypocalcemia, analgesic drug use,postoperative wound infection or postoperative hospitalization days.
The incidence of intraoperative mild hypothermia after active warming was high in elderly patients who underwent abdominal surgery. Mild hypothermia increased the incidence of shivering and prolonged anesthesia recovery time in elderly patients undergoing abdominal surgery.
本研究旨在探讨术中低体温对老年腹部手术患者麻醉恢复期的影响。
基于纳入和排除标准，进行了一项前瞻性观察性研究。2021 年 10 月至 2022 年 10 月，在四川省成都市一家 A 级三级医院，共纳入 384 例接受全身麻醉下腹部手术的老年患者。麻醉诱导后，常规使用充气式升温毯进行主动保温，并监测鼻咽温度，观察术中低体温的发生情况。根据术中是否发生低体温，将患者分为低体温组和非低体温组。比较两组患者的麻醉恢复时间及麻醉恢复期间不良事件或不良事件的发生率。
384 例行腹部手术的患者中，240 例（62.5%）患者发生术中低体温，均为轻度低体温。与非低体温患者相比，主动升温后轻度低体温患者的寒战发生率（χ2=5.197，P=0.023）和麻醉恢复时间（Z=-2.269，P=0.02）差异均有统计学意义，而两组患者在低氧血症、恶心或呕吐、高血压、低钾血症、低钙血症、镇痛药使用、术后伤口感染或术后住院天数方面差异均无统计学意义。
腹部手术老年患者主动升温后，术中轻度低体温的发生率较高。轻度低体温增加了腹部手术老年患者寒战的发生率，并延长了麻醉恢复时间。
