Objective To explore the changes of intraoperative temperature and influencing factors of the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms.Methods The basic clinic data and intraoperative temperature of patients undergoing elective clipping of posterior communicating artery aneurysms between October 2018 and July 2019 were collected, and the minimum intraoperative temperature was categorized into ≥36.0 and <37.5℃, ≥35.0 and <36.0℃, and <35.0℃. According to the Glasgow outcome scale (GOS) at discharge, the patients were divided into good prognosis group (GOS 4-5) and bad prognosis group (GOS 1-3). Multiple logistic regression analysis was used to obtain the risk factors of short-term prognosis.Results A total of 127 cases were involved, and intraoperative hypothermia (<36.0℃) occurred in 64 cases (50.4%). The intraoperative temperature presented classical three-phrase changes, i.e. it dropped rapidly at 1 hour after anesthesia introduction, decreased slowly during 2-3 hours after anesthesia introduction, and then entered the plateau. In the 127 cases, 93 (73.2%) had good prognosis, with an intraoperative hypothermia proportion of 44.1% (41/93); and 34 (26.8%) had bad prognosis, with an intraoperative hypothermia proportion of 67.6% (23/34). Univariate analysis showed that Hunt-Hess grade (χ2=18.999, P<0.001), intraoperative bleeding (χ2=7.074, P=0.008), minimum intraoperative temperature (Z=−3.473, P=0.001), and postoperative complications (χ2=43.060, P<0.001) were related to the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms. Multiple logistic regression analysis presented that high Hunt-Hess grade (Ⅳ, Ⅴ) [odds ratio (OR)=6.456, 95% confidence interval (CI) (1.141, 36.532), P=0.035], the minimum intraoperative temperature <35.0℃ [OR=7.552, 95%CI (1.450, 39.345), P=0.016], and postoperative complications [OR=22.866, 95%CI (6.778, 77.142), P<0.001] were independent risk factors of the short-term prognosis. The difference in short-term prognosis between patients with the minimum intraoperative temperature ≥35.0 and <36.0℃ and the ones with the minimum intraoperative temperature ≥36.0 and <37.5℃ was not statistically significant (P>0.05).Conclusions The minimum intraoperative temperature<35.0℃ and postoperative complications were changeable factors to effect progonosis of patients undergoing elective clipping of posterior communicating artery aneurysms. Clinical staff should set medical intervention measures based on the individual conditions of patients to improve patients’ quality of life.
