The aim of this study was to investigate the efficacy of limiting increases in theatre ambient temperature to 27°C to prevent intraoperative patient hypothermia.
This single-centre, comparative cohort clinical study investigated the management of theatre ambient temperatures involving patients with ≥ 20 % TBSA burn injuries at Victorian Adult Burns Service (Melbourne, Australia). Data from the intervention group (August 2021 - February 2023, theatre ambient temperature increase limited to 27°C) was compared with a historical cohort (August 2019 - August 2021). Patient hypothermia was defined as core temperature below 36°C.
In total, 29 patients underwent 107 surgical procedures in the operating theatre. Patient hypothermia was recorded on 45 occasions (42.1 %) and of these, between 35.1 and 36.0°C on 28 occasions (62.2 %). There was no statistically significant difference in the incidence of hypothermia, hospital LOS, ICU LOS, total operations, or mortality between the study cohort and historical cohort. Patients who suffered hypothermia had lower BMI, lower preoperative temperature, and shorter ICU LOS.
Increasing theatre ambient temperature to 27°C is adequate in most cases. A more nuanced approach with selective increase of theatre ambient temperature beyond 27°C, only where clinically indicated, is a refinement that will benefit both patients and staff.
本研究的目的是调查将手术室环境温度升高限制在27°C以预防术中患者体温过低的效果。
这项单中心、比较队列临床研究调查了澳大利亚墨尔本维多利亚成人烧伤服务中心对≥20%体表面积烧伤患者的手术室环境温度管理。将干预组（2021年8月至2023年2月，手术室环境温度升高限制在27°C）的数据与一个历史队列（2019年8月至2021年8月）进行比较。患者体温过低定义为核心温度低于36°C。
共有29名患者在手术室接受了107次手术。记录到45次患者体温过低情况（42.1%），其中28次（62.2%）体温在35.1至36.0°C之间。研究队列与历史队列在体温过低发生率、住院时间、重症监护病房住院时间、总手术次数或死亡率方面无统计学显著差异。体温过低的患者体重指数较低、术前体温较低且重症监护病房住院时间较短。
在大多数情况下，将手术室环境温度升高到27°C就足够了。采用一种更细致入微的方法，仅在临床指征明确时才将手术室环境温度选择性地升高到27°C以上，这将使患者和工作人员都受益。
