Acute Adverse Effects of Formaldehyde Treated Cadaver on New Innovative Medical Students and Anatomy Staff Members in the Dissection Hall at Wollo University, Northeast Ethiopia.

INTRODUCTION

Formaldehyde is the most frequently used chemical for the preservation of a cadaver. However, its toxicity in the dissection hall is frequently ignored.

OBJECTIVE

To assess the acute adverse effects of formaldehyde treated cadaver on preclinical new innovative medical students and anatomy staff members in the dissection hall at Wollo University, Ethiopia.

METHODS

This institutional-based cross-sectional study was carried out from January 20 to February 25, 2020. A total of 88 study participants were surveyed at the department of Human Anatomy, Wollo University, Ethiopia. The participants were those who were exposed to formaldehyde vapors during the dissection of a cadaver in the dissection hall. A self-administered questionnaire which contains the clinical symptoms observed after formaldehyde exposure was used to collect data. The data were entered into EpiData version 4.2 and then exported to SPSS Version 21 for analysis. Finally, the data were expressed in texts, tables, and figures.

RESULTS

The study comprised 84 (95.5%) male and 4 (4.5%) female. In this study, the top three most common acute adverse effects of formaldehyde during dissection of a cadaver in the cadaver room were unpleasant smells, Tiredness/dizziness, and watering of eyes (lacrimation), each accounted for 64 (72.7%), 39 (44.3%) and 35 (39.8%), respectively. The other acute adverse effects were running nose with tingling sensation 27 (30.7%) followed by lack of concentration 24 (27.3%) and headache 22 (25%).

CONCLUSION

In dissection hall, preclinical medical students and instructors are at high risk to develop various acute adverse symptoms of formaldehyde. Therefore, a free-aldehyde preservation solution should be assumed to prevent its toxicity.
