  • Effectiveness of Forced Air Warming for the Maintenance of Perioperative Core Temperature: A Meta-Analysis

    Objective To systematically review the effectiveness of forced air warming for the maintenance of perioperative core temperature, so as to provide clinical evidence for an appropriate warming plan during the perioperative period. Methods We electronically searched PubMed, The Cochrane Library, EMbase, Web of Science, CBM and CNKI from 2000 to 2012, so as to comprehensively collect randomized controlled trials (RCTs) about the effectiveness of different warming methods for the maintenance of perioperative core temperature (including forced air warming, resistive-heating blanket/electric heating pad, circulating water mattress, and infrared ray radiant heating system) for maintenance of perioperative core temperature. References of the included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results Eleven RCTs involving 577 patients were included. The results of meta-analysis indicated that, in the maintenance of core temperature during the perioperative period, forced air warming was superior to resistive-heating blanket/electric heating pad (SMD= –0.40, 95%CI –0.73 to –0.06), circulating water mattress (SMD= –1.10, 95%CI –1.55 to –0.66), and infrared ray radiant heating system (SMD= –0.69, 95%CI –1.06 to –0.32). In the incidence of hypothermia during the perioperative period, the group of forced air warming was lower than the group of blanket/electric heating pad (RR=1.76, 95%CI 1.15 to 2.69), but it was the same as the group of infrared ray radiant heating system (RR=1.37, 95%CI 0.83 to 2.27). In the incidence of shivering during the perioperative period, the group of forced air warming was the same as the group of blanket/electric heating pad (RR=0.75, 95%CI 0.18 to 3.21) and the group of infrared ray radiant heating system (RR=0.8, 95%CI 0.19 to 3.36). Conclusion Compared with resistive-heating blanket/electric heating pad, circulating water mattress, and infrared ray radiant heating system, forced air warming maintains patients’ core temperature better during the perioperative period, with a lower incidences of hypothermia. Due to the limited quantity and quality of the included studies, more high quality RCTs with large sample size are needed to verify the above conclusion.

  • 手术患者术中体温变化规律的临床研究

    目的探讨手术患者术中低体温的发生率、降低程度、发生术中低体温的重点人群及手术方式。 方法采用便利抽样的方法将2013年7月-9月符合标准的手术患者170例作为研究对象。在患者全身麻醉后采用食道探头监测患者术中的体温,每半小时记录1次,了解患者麻醉后、手术开始后、打开腹腔后以及手术结束后的体温变化曲线。 结果手术患者低体温率为52.9%(90/170)。开腹手术和神经外科手术低体温发生率较高,但各手术类型低体温发生率差异无统计学意义(P>0.05)。10例患者监测过程中发现体温过低,低至34.7℃,中途采用主动保温措施退出研究。手术患者术中体温变化可划分为4个阶段:下降期、快速下降期、平台期、上升期。 结论手术患者术中未普遍采取主动加温措施,低体温发生率高。在手术结束前,随着手术时间的延长,体温逐渐降低。

  • Analysis in the influencing factor of intraoperative hypothermia during laparotomy

    ObjectiveTo investigate the influencing factor of intraoperative hypothermia during laparotomy.MethodsA total of 81 patients underwent laparotomy in our hospital from October 1, 2018 to January 1, 2019 were enrolled. The difference of preoperative baseline data and surgical data between the hypothermia and non-hypothermia groups was compared, and the influencing factor of intraoperative hypothermia during laparotomy was explored.ResultsOf the 81 patients, 32 patients occurred hypothermia during operation. There were no significant differences in gender, age, BMI, HGB, WBC count, PLT count, TB, AST, ALT, ALB, PT, operation time, postoperative hospital stay, and Clavien-Dindo grade between the hypothermia group and the non-hypothermia group (P>0.05), but there were significant differences in intraoperative infusion volume, intraoperative blood loss, and surgical mode (P<0.05). The intraoperative infusion volume and intraoperative blood loss in the hypothermia group were higher than those in the non-hypothermia operation group, and the proportion of hepatectomy was higher than that in the non-hypothermia group. The multivariate analysis show that the intraoperative blood loss, intraoperative infusion volume, and kind of operation were the risk factors for the hypothermia during laparotomy (P<0.05).ConclusionsIntraoperative hypothermia is related to intraoperative bleeding volume, intraoperative fluid infusion volume, and the kind of operation. Therefore, for patients with less bleeding, the intraoperative hypothermia can be reduced by limiting the volume of intraoperative fluid infusion. For those patients with more intraoperative bleeding, warming fluid infusion may reduce the incidence of intraoperative hypothermia.

  • The changes of intraoperative temperature and risk factors of prognosis of patients undergoing clipping of posterior communicating artery aneurysms

    ObjectiveTo explore the changes of intraoperative temperature and influencing factors of the short-term prognosis of patients undergoing clipping of posterior communicating artery aneurysms.MethodsThe 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.ResultsA 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).ConclusionsThe 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.
