Abstract: Objective: To investigate the effect of Forced-air Warming and Carbon-fibre Polymer-fabric Resistive Heating on the prevention of Inadvertent Perioperative Hypothermia (IPH). Methods: We searched Chinese and English databases from inception to March 2021 to collect Randomized Controlled Trials on Forced-air Warming versus Carbon-fibre Polymer-fabric Resistive Heating for prevention of IPH in adults. Two reviewers independently screened the literatures, extracted the data, and assessed the risk of bias of included studies. Results: A total of 16 studies were included. Meta-analysis results showed that compared with Carbon-fibre Polymer-fabric Resistive Heating, Forced-air Warming raised core body temperature 90 minutes after induction of anesthesia [SMD=0.42, 95%CI (0.07, 0.77)] and at the end of the procedure [SMD=0.41, 95%CI (0.28, 0.54)]. Conclusion: Current evidence shows that compared with Carbon-fibre Polymer-fabric Resistive Heating, Forced-air Warming can better maintain the core body temperature of perioperative patients. It can provide reference for perioperative temperature management.
