Operating room (OR) temperature may impact the performance of health care providers. This study assesses whether hot or cold room temperature diminishes the performance of OR personnel measured by psychomotor vigilance testing (PVT) and self-report scales.
This prospective observational study enrolled surgical/anesthesia trainees, student registered nurse anesthetists, and certified registered nurse anesthetists. Each provider participated in a test of psychomotor function and a questionnaire using a self-report scale of personal comfort and well-being. The PVT and questionnaires were completed after 30 minutes of exposure to 3 different conditions (temperature of 21°C, 23°C, and 26°C).
The cohort of 22 personnel included 9 certified registered nurse anesthetists, 7 anesthesia/surgical trainees, and 6 student registered nurse anesthetists. Mean reaction time on the PVT was comparable among baseline (280 ± 47 ms), hot (286 ± 55 ms; = 0.171), and cold (303 ± 114 ms; = 0.378) conditions. On the self-report score (range, 1-21), there was no difference in the self-rated subjective performance between baseline and cold conditions. However, the self-rated subjective performance scale was lower (12 ± 6, = 0.003) during hot conditions.
No difference was noted in reaction time depending on the temperature; however, excessive heat in the OR environment was associated with worse self-rated subjective performance among health care providers. Particularly, self-rated subjective physical demand and frustration were greater under hot condition.
手术室温度可能会影响医护人员的工作表现。本研究旨在评估高温或低温环境是否会降低通过精神运动警觉性测试（PVT）和自我报告量表衡量的手术室工作人员的表现。
这项前瞻性观察性研究纳入了外科/麻醉实习生、注册护士麻醉专业学生和注册护士麻醉师。每位参与者都参加了一项精神运动功能测试和一份使用个人舒适度和幸福感自我报告量表的问卷。在暴露于3种不同条件（21°C、23°C和26°C）30分钟后完成PVT和问卷。
22名参与者包括9名注册护士麻醉师、7名麻醉/外科实习生和6名注册护士麻醉专业学生。PVT的平均反应时间在基线（280±47毫秒）、高温（286±55毫秒；P = 0.171）和低温（303±114毫秒；P = 0.378）条件下相当。在自我报告得分（范围为1 - 21）方面，基线和低温条件下的自我评定主观表现没有差异。然而在高温条件下，自我评定主观表现量表得分较低（12±6，P = 0.003）。
根据温度不同，反应时间没有差异；然而，手术室环境中的过热与医护人员自我评定的主观表现较差有关。特别是在高温条件下，自我评定的主观身体需求和挫败感更大。
