To examine the effect of large-scale repair work on indoor formaldehyde (FA) levels and subjective symptoms in medical students during a gross anatomy dissection course.
We measured the indoor FA levels, room air temperature, and room humidity during a gross anatomy dissection course. In addition, the prevalence of subjective symptoms, keeping allergy state, and wearing personal protective equipment were surveyed in two groups of students using a self-administered questionnaire.
The mean indoor FA levels before and after repair work were 1.22 ppm and 0.14 ppm, respectively. The mean indoor FA level significantly decreased after repair work. The prevalences of most subjective symptoms before the anatomy practice were similar before and after the repair work. However, the prevalences of most subjective symptoms during the anatomy practice were lower after the repair work.
The mean indoor FA levels and prevalences of subjective symptoms decreased after the repair work. We have to continuously monitor indoor FA levels, carry out private countermeasures to minimize exposure to FA, and maintain equipment for ventilation to be able to conduct practice in a comfortable environment.
研究大规模维修工作对医学生在大体解剖课程期间室内甲醛（FA）水平及主观症状的影响。
在大体解剖课程期间，我们测量了室内FA水平、室温及室内湿度。此外，使用自填式问卷对两组学生的主观症状发生率、过敏状态及个人防护装备佩戴情况进行了调查。
维修工作前后室内FA平均水平分别为1.22 ppm和0.14 ppm。维修工作后室内FA平均水平显著下降。解剖实习前大多数主观症状的发生率在维修工作前后相似。然而，解剖实习期间大多数主观症状的发生率在维修工作后较低。
维修工作后室内FA平均水平及主观症状发生率降低。我们必须持续监测室内FA水平，采取个人应对措施以尽量减少FA暴露，并维护通风设备，以便能够在舒适的环境中进行实习。
