复合保温策略在腹腔镜手术患者术中低体温预防中的应用研究

摘要

目的 探讨复合保温策略在腹腔镜手术患者术中低体温预防中的应用效果，为降低术中低体温发生率提供参考。方法 选取2025年1月-3月期间，我院手术室接收的1010例腹腔镜手术患者作为研究对象，将其随机分为对照组和实验组，对照组505例，实验组505例。对照组采用常规保温措施，包括盖被保暖、调节手术室温度等；实验组采用复合保温策略，即在常规保温基础上，增加暖风毯保温、加温输液输血、加温腹腔冲洗液等措施。观察指标为术中低体温发生率、体温波动幅度及术后苏醒时间。结果 实验组术中低体温发生率为5.1%（26/505），低于对照组的23.4%（118/505），差异有统计学意义（χ2=68.325，P=0.000）；实验组体温波动幅度为（0.8±0.3）℃，小于对照组的（1.5±0.5）℃，差异有统计学意义（t=26.784，P=0.000）；实验组术后苏醒时间为（18.5±5.2）分钟，短于对照组的（25.3±6.8）分钟，差异有统计学意义（t=16.357，P=0.000）。结论 复合保温策略可有效降低腹腔镜手术患者术中低体温发生率，减少体温波动，缩短术后苏醒时间，值得在临床推广应用。

Abstract

Objective To explore the application effect of composite thermal insulation strategy in preventing intraoperative hypothermia in patients undergoing laparoscopic surgery, and to provide a reference for reducing the incidence of intraoperative hypothermia.
Methods A total of 1010 patients undergoing laparoscopic surgery in the operating room of our hospital from January to March 2025 were selected as the research subjects. They were randomly divided into the control group and the experimental group, with 505 cases in each group. The control group adopted conventional thermal insulation measures, including keeping warm with quilts and adjusting the temperature of the operating room. The experimental group adopted a composite thermal insulation strategy, which added warm air blanket insulation, heated infusion and blood transfusion, and heated abdominal irrigation fluid on the basis of conventional thermal insulation. The observation indicators included the incidence of intraoperative hypothermia, the amplitude of body temperature fluctuation, and the postoperative awakening time.
Results The incidence of intraoperative hypothermia in the experimental group was 5.1% (26/505), which was lower than 23.4% (118/505) in the control group, and the difference was statistically significant (χ2=68.325, P=0.000). The amplitude of body temperature fluctuation in the experimental group was (0.8±0.3)℃, which was smaller than (1.5±0.5)℃ in the control group, with a statistically significant difference (t=26.784, P=0.000). The postoperative awakening time in the experimental group was (18.5±5.2) minutes, which was shorter than (25.3±6.8) minutes in the control group, and the difference was statistically significant (t=16.357, P=0.000).
Conclusion   The composite thermal insulation strategy can effectively reduce the incidence of intraoperative hypothermia, decrease body temperature fluctuation, and shorten the postoperative awakening time in patients undergoing laparoscopic surgery, which is worthy of clinical promotion and application.
