手术室全程积极保温策略对老年腹部手术患者低体温及寒战的预防作用

目的 探讨手术室全程积极保温策略对老年腹部手术患者低体温及寒战的预防作用。 方法 选取2022年10月至2023年3月浙江省嘉兴市第二医院接受腹部手术的老年患者82例，根据随机数字表法将其分为对照组（常规保温护理）及观察组（手术室全程积极保温策略），各41例。比较两组不同时间点体温、术中低体温发生情况、寒战发生情况及分级、麻醉苏醒指标、不良反应。 结果 两组体温不同时间、组间及交互作用比较，差异有统计学意义（P＜0.05），两组手术30 min、术毕体温均高于术前，且观察组高于对照组（P＜0.05）。观察组术中低体温发生率、寒战发生率均低于对照组（P＜0.05）。观察组寒战分级情况优于对照组（P＜0.05）。观察组自主呼吸恢复时间、意识恢复时间、下床活动时间、住院时间均短于对照组（P＜0.05）；观察组不良反应发生率低于对照组（P＜0.05）。结论 手术室全程积极保温策略能稳定老年腹部手术患者体温，有效预防低体温及寒战，改善苏醒质量，促进术后恢复，减少不良反应。

Prevention effect of whole-course active thermal insulation strategy in operating room on hypothermia and chills in elderly patients undergoing abdominal surgery

Objective To explore the prevention effect of whole-course active thermal insulation strategy in operating room on hypothermia and chills in elderly patients undergoing abdominal surgery. Methods A total of 82 elderly patients who underwent abdominal surgery in Jiaxing Second Hospital, Zhejiang Province were enrolled between October 2022 and March 2023. According to random number table method, they were divided into control group (routine thermal insulation nursing) and observation group (whole-course active thermal insulation strategy in operating room), with 41 cases in each group. The body temperature at different time points, occurrence of intraoperative hypothermia, occurrence and grading of chills, anesthesia recovery indexes, and adverse reactions were compared between the two groups. Results There were statistically significant differences in body temperature between the two groups at different time, between groups and interaction (P＜0.05). The body temperature of the two groups at 30 min and after operation were higher than those before operation, and those in the observation group were higher than those in the control group (P＜0.05). The incidence of intraoperative hypothermia and chills in the observation group were lower than those in the control group (P＜0.05). Shivering grade of observation group was better than control group (P＜0.05). The recovery time of spontaneous respiration, consciousness recovery time, getting out of bed activity time and hospitalization time in observation group were shorter than those in control group (P＜0.05). The incidence of adverse reactions in observation group was lower than that in control group (P＜0.05). Conclusion The whole-course active thermal insulation strategy in operating room can stabilize body temperature, effectively prevent hypothermia and chills, improve recovery quality, promote postoperative recovery and reduce adverse reactions in elderly patients undergoing abdominal surgery.
