Abstract

Background: Postoperative hypothermia seems to be a common problem in surgical patients but is easily ignored. This study aimed to identify risk factors for postoperative hypothermia in non-cardiac surgery patients.

Methods: We searched databases including PubMed, Embase, Web of Science, Cochrane Library, CINAHL, VIP, Wan Fang, CNKI, and CBM from inception to April 2025. The studies were selected using inclusion and exclusion criteria. Two reviewers screened studies, extracted data, and independently evaluated the risk of bias. The quality of the study was assessed with the Newcastle-Ottawa Scale, and a meta-analysis was carried out with Revman 5.4 software.

Results: A total of 17 studies were included. Age ≥ 60 (odds ratio [OR] = 1.80), BMI < 18.5 kg/m² (OR = 1.83), ASA III-IV (OR = 1.87), endoscopic surgery (OR = 1.93), intraoperative blood loss ≥ 100ml (OR = 2.35), intravenous fluid ≥ 1000ml (OR = 1.87), blood transfusion (OR = 1.80), duration of anesthesia > 1 h (OR = 1.99) and duration of surgery > 1 h (OR = 2.34) were significant risk factors that contributed to postoperative hypothermia in non-cardiac surgery patients.

Conclusion: There are many risk factors for postoperative hypothermia in patients undergoing non-cardiac surgery. The results of this research may improve clinician awareness, risk stratification, and prevention of postoperative hypothermia in non-cardiac surgery patients.

非心脏手术患者术后低体温的危险因素：系统回顾和荟萃分析。

背景：术后低体温似乎是外科患者的一个常见问题，但很容易被忽视。本研究旨在确定非心脏手术患者术后低体温的危险因素。方法：检索PubMed、Embase、Web of Science、Cochrane Library、CINAHL、VIP、万方、CNKI、CBM等数据库，检索时间自成立至2025年4月。采用纳入和排除标准选择研究。两名审稿人筛选研究，提取数据，并独立评估偏倚风险。采用Newcastle-Ottawa量表评估研究质量，并采用Revman 5.4软件进行meta分析。结果：共纳入17项研究。年龄≥60岁（比值比[OR] = 1.80）、BMI 2 （OR = 1.83）、ASA III-IV （OR = 1.87）、内镜手术（OR = 1.93）、术中出血量≥100ml （OR = 2.35）、静脉输液≥1000ml （OR = 1.87）、输血（OR = 1.80）、麻醉时间> h （OR = 1.99）、手术时间> h （OR = 2.34）是导致非心脏手术患者术后低体温的重要危险因素。结论：非心脏手术患者术后低体温的危险因素较多。本研究的结果可能会提高临床医生对非心脏手术患者术后低温的认识、风险分层和预防。
