Objective To investigate the incidence of intraoperative hypothermia in elderly patients,and to analyze and discuss related influencing factors and targeted management strategies.Methods From February 2017 to February 2019,220 elderly patients admitted into our hospital for surgery were selected.According to whether or not they had intraoperative hypothermia,patients were divided into the hypothermia group and the non-hypothermia group.General information and surgical data were compared between the two groups.Measures for the prevention of intraoperative hypothermia were discussed.Results Of the 220 patients,103 had intraoperative hypothermia,and the incidence rate was 46.8％.The proportion of patients aged ≥70 years or with BMI ＜24 kg/m2 was higher in the hypothermia group than in the non-hypothermia group (all P ＜ 0.05).The proportion of patients with the anesthesia time ≥60 min or total intraoperative fluid intake ≥2000 ml was higher in the hypothermia group than in the non-hypothermia group(all P＜0.05).BMI ＜24 kg/m2 and total intraoperative fluid intake ≥ 2000 ml were the key risk factors for intraoperative hypothermia in elderly patients(all P＜0.05).Conclusions Intraoperative hypothermia is a common complication for elderly patients undergoing surgery.Intraoperative fluid intake and body mass are the key risk factors for intraoperative hypothermia.Targeted treatment measures based on the above related factors should be considered for elderly patients receiving surgery.%目的 分析老年手术患者术中低体温发生情况,并对其相关影响因素和针对性处理对策进行探讨. 方法 选取2017年2月至2019年2月本院各科手术室所收治老年手术患者220例,按照是否出现术中低体温将其分为低体温组和非低体温组,对两组患者一般资料和手术资料进行对比分析,并对术中低体温预防措施进行探讨. 结果 220例老年手术患者共计出现术中低体温103例,发生率为46.8％;低体温组中年龄≥70岁、体质指数(BMI)＜24 kg/m2比例高于非低体温组(均P＜0.05);低体温组患者麻醉时间≥60 min、液体总入量≥2 000 ml所占比例均高于非低体温组(均P＜0.05);BMI＜24 kg/m2、术中液体总入量≥2 000 ml均是影响老年患者术中出现低体温的危险因素(均P＜0.05). 结论 术中低体温是一种常见老年患者手术并发症,术中液体输入量、体质量是影响术中低体温发生的关键因素,应从以上因素对老年手术患者实施针对性处理.
