Abstract

The genetic material is exposed to several toxic agents, which can induce damage, causing alterations in the genome. Reports have shown that chronic exposure to inhalational anesthetics may have negative impact on health. Therefore, the evaluation of the effect of exposure to waste anesthetic gases on newly exposed professionals who work in operating rooms without still adequate exhaust system and air exchange is relevant. In this study, we will assess DNA damage in medical residents exposed to waste anesthetic gases for three years (at the end of residency). Thus, the study will be conducted in 40 medical residents, allocated into two groups according to occupational exposure or not (control) to waste anesthetic gases. Blood samples will be collected and coded, and lymphocytes will be isolated for evaluation of DNA damage by the comet assay. Our data will help to better understand the impact of occupational exposure to inhalational anesthetics on the genome of young professionals.
