[摘要] 目的：探讨全身麻醉下行开腹手术患者术中保温对术后苏醒延迟及寒战的影响。方法：选择择期ASAⅠ～Ⅱ级50～60岁开腹子宫全切术女性患者120例，随机分为两组：A组(60例)术中未进行任何保温措施，B组(60例)术中使用热风毯与加温输液仪。回顾性分析这两组患者全麻后苏醒延迟及寒战的发生率及原因。结果：A组患者发生术后苏醒时间为(8.7±1.9)min，寒战发生率为31.7%；B组术后苏醒苏醒时间为(5.3±1.1)min，寒战发生率为6.7%。结论：术中保温是一种预防术后寒战、促进全麻苏醒的简捷有效的方法。充分的术中保温是保证手术成功的重要环节，并直接影响疾病的预后。

[Abstract] Objective: To investigate the effects of intraoperative warming for postoperative delayed recovery and preservation of shivering after general anesthesia in patients undergoing abdominal surgery. Methods: 120 female abdominal hysterectomy patients who were ASA Ⅰ-Ⅱ grade and 50 to 60 years old were divided into two groups randomly. Group A (60 cases) did not have any insulation measures in surgery, group B (60 cases) were performed intraoperative infusion of hot air blanket and heating apparatus during opertion. These two sets of delayed recovery after general anesthesia and the incidence and causes chills were retrospective analysed. Results: Group A of patients with postoperative recovery time was (8.7±1.9) min, and the incidence of shivering were 31.7%. Group B patients with postoperative recovery time was (5.3±1.1) min, and the incidence of shivering rate was 6.7%. Conclusion: Intraoperative warming is the simple and effective method to prevente the postoperative shivering, and promote recovery from general anesthesia. Sufficient intraoperative warming is an important part to ensure successful operation and directly affect the prognosis.

正常的体温是机体进行新陈代谢和正常生命活动的必要条件，人体通过自主性和行为性体温调节功能维持体温的恒定。麻醉和开腹手术时行为性体温调节能力丧失，单纯依赖体温调节中枢调控机体的产热和散热不足以维持体温的恒定，所以围术期普遍存在体温失衡的现象[1]。体温降低会对人体的内环境、正常的生理功能和药物的代谢速率造成影响，从而影响机体正常的生理活动。正常情况下人体体温恒定在(37 ......
