Subjective symptoms of medical students exposed to formaldehyde during a gross anatomy dissection course.

ABSTRACT

The purpose of this study is to investigate the safety of and to try to find the best plan to cope with exposure to FA for students during a gross anatomy dissection course. The FA exposure level and subjective symptoms was estimated. The relationship between exposure to FA and subjective symptoms of irritation were discussed for times; before, in the beginning period, in the middle period, and upon completion of the Anatomy Dissection Course. The geometric means of FA concentration were 32.7 micrograms/m3 (before), 891.3 micrograms/m3 (beginning), 763.3 micrograms/m3 (middle), and 238.9 micrograms/m3 (completion), respectively. Among them, FA-related symptoms were observed in 61.1 percent; 28.0 percent fell strong stress during the course, and 27.4 percent complained that their normal life situation was affected. Our results indicate that such subjective symptoms during the anatomy dissection course were related to the period spent in the anatomy dissection room. Our study suggests that shortening the time of each anatomy dissection practical class and reduction of the number of cadaver tables could help to reduce symptoms.
