Management of chemical health hazard fumes emitted during and after embalming procedure and its impact on medical students and embalmers

Abstract

The process of human cadaveric preservation uses diverse embalming formulas introduced in cadavers by means of various technical approaches. Successful embalming requires the use of adequate formulas and techniques to fulfil a long-term structural preservation and minimize shrinkage and any harmful toxic effects to personal and environment. Our aim in this study is to generate a high-quality embalming formula that generate superior embalming and to minimize chemical toxic fumes emitted that students and embalmers are exposed to. An altered low formaldehyde based formula was used in our laboratories and introduced in cadavers through arterial injection using gravity infusion pressure. Results indicate an even distribution of the formula observed exhibiting superior tissue quality and excellent joint flexibility. Final formaldehyde concentration within the embalmed cadavers was minimal. The ambient fumes detected were significantly reduced when compared with other formula’s used complying with international permitted values. There was significant reduction in the symptoms the students complain about during and after contact with cadavers. We conclude that this modified formula yields a higher quality preserved cadavers with high flexibility and colour preservation. A reduction of the unwanted ambient hazardous toxic effects of formaldehyde and other chemical fumes was achieved.
