全身麻醉术后患者苏醒室内低体温发生率及其影响因素的Logistic回归分析.

Objective: To investigate the incidence of hypothermia after general anesthesia and analyze its influencing factors. Methods: 110 patients with general anesthesia in our hospital from May 2020 to October 2020 were selected as the research objects, and methods retrospective analysis was used to sort out the patient's medical records. The incidence of hypothermia in the wake-up room of patients after general anesthesia was observed. Patients with hypothermia were classified as hypothermia group and those without hypothermia were classified as normal body temperature group. Logistic regression was used to analyze the related factors of hypothermia. Results: There were 15 patients with hypothermia after general anesthesia. The incidence of hypothermia was 13.64% (15/110). Univariate analysis showed that the incidence of postoperative hypothermia in patients after general anesthesia was related to age, anesthesia time, operation time, American Society of Anesthesiologists (ASA) classification, recovery delay and intraoperative infusion volume (P<0.05), but not with gender, body mass index, intraoperative ambient temperature and preoperative hemoglobin (P>0. 05). Multivariate Logistic regression analysis showed that operation time > 4h, ASA grade Ⅲ ~ Ⅳ, intraoperative infusion volume > 1300 mL, age > 60 years old were the influencing factors of the occurrence of postoperative hypothermia in patients after general anesthesia (P<0.05). Conclusions: The occurrence of hypothermia in the wake-up room of patients after general anesthesia is inevitable, and it is affected by many factors. It is necessary to shorten the operation time as far as possible, do a good job in heat preservation of input liquid, especially for elderly patients, so as to reduce the risk of hypothermia.
