麻醉前预保温对TURP老年患者围术期低体温的防治效果

Preventive Effect of Prewarming Interven-tion Prior to Anesthesia on Perioperative Hypothermia in Elderly Patients with TURP

摘要: 目的：探讨麻醉前预保温对TURP老年患者围术期低体温的防治效果。方法：选择2018年5月~2019年8月期间在北仑区人民医院行TURP手术的老年患者90例，随机分为三组(n = 30)，即麻醉前预保温组(PW组)、麻醉后保温组(CW组)和对照组(CO组)。麻醉前预保温组于麻醉前20分钟采用主动充气加温系统进行预保温；麻醉后保温组于麻醉诱导后给予主动充气加温系统保温；对照组仅采取常规保温措施。分别观察三组患者的围术期核心体温变化、低体温发生率、以及术后复苏时间等指标。结果：三组患者的年龄、基础体温、BMI、手术时间、术中灌洗液容量等数据比较，均未见统计学差异(P > 0.05)。但术中体温、围术期低体温发生率及术后复苏时间的组间比较存在明显差异(P < 0.05)。与对照组相比，PW组的术中体温明显升高(P = 0.014)，围术期低体温率明显降低(P = 0.011)，术后复苏时间明显缩短(P = 0.040)。但CW组与对照组比较未见统计学差异(P > 0.05)。结论：对于短小的老年患者TURP手术，麻醉前预保温可明显减少术中低体温的发生，并缩短术后复苏时间。

Abstract: Objective: To explore the preventive effect of prewarming intervention prior to anesthesia on perioperative hypothermia in elderly patients with TURP. Methods: Between May 2018 and Au-gust 2019, ninety elderly patients undergoing TURP were randomly divided into three groups (n = 30), that is, prewarming group (PW), cowarming group (CW), and control group (CO). In PW group, prewarming intervention with active inflation heating system initiated 20 minutes prior to the induction of anesthesia, and in PW group, warming intervention initiated simultaneously after the induction of anesthesia, while in control group, routine warming intervention was performed during perioperative period. The changes in body core temperature during the peri-operative period, the incidence of hypothermia and postoperative recovery time were observed in the three groups. Results: There were no statistical differences in age, BMI, operation time, and intraoperative perfusion volume among the three groups (P > 0.05). However, compared with those of control group, higher intraoperative core temperature (P = 0.014), lower inci-dence of hypothermia (P = 0.011) and shorter postoperative recovery time (P = 0.040) were observed in PW group, but not in CW group (P > 0.05). Conclusion: For short-term surgery of TURP in elderly patients, prewarming intervention prior to anesthesia can significantly reduce the incidence of perioperative hypothermia and shorten the postoperative recovery time.
