外科手术中热应力对手术人员操作能力和感知功能的影响

Effect of thermal stress on surgical ability and cognitive function of operating personnel

目的 评估手术室环境温度对手术人员操作能力和感知功能的影响。方法 27名外科实习医师分入两种手术环境中(19℃和26℃)进行动物手术,使用外科操作能力评价表评估手术操作能力,手术任务负荷指数评估感知压力。结果 两种手术环境(19℃和26℃)条件下,外科实习医师的无菌技术和手术基本操作技术评分差异无统计学意义(P>0.05)。与低室温相比,高室温下身体需求和分心更明显(P<0.01)。结论 提高手术室环境温度不会大幅降低短期手术操作的技术能力,但增加外科医生分心和身体感知需求。

Objective To assess the impact of operating room temperature on surgical ability and cognitive function of operating personnel. Methods Twenty-seven surgical interns entered the operating rooms at 19 ℃ or 26 ℃ for animal surgery. The surgical ability and perceived stress were evaluated using surgical ability evaluation form and Surgical Task Load Index. Results There were no significant differences in aseptic technique and basic surgical technique scores between two environmental temperatures of 19 ℃ and 26 ℃(P>0.05). Physical demand and distraction were more evident at higher room temperature than at lower room temperature(P<0.01). Conclusion The increased operating room temperature has little effect on short-term surgical performance, but enhances the body perception and distraction.
