Description
Summary:ABSTRACT Objective: To determine the relative risk and time to development of signs and symptoms related to exposure to surgical smoke in resident physicians. Method: Prospective cohort, with 55 resident physicians exposed to surgical smoke and 45 unexposed. Collection took place in two hospital institutions in southern Brazil, in eight moments, from March 2018 to February 2020, using a form containing sociodemographic and labor information, signs, symptoms and self-reported preventive measures, conducted by trained researchers, who followed the participants throughout the process. Descriptive statistics, Chi-square, COX regression and Kaplan-Meier were used to analyze association, risk and time of onset of signs and symptoms. Results: Exposed residents were 1.5 times more likely to develop signs and symptoms (95% CI: 0.99-2.42; p=0.05). The most common respiratory and eye symptoms were the sensation of a foreign body in the throat (HR: 3.86; p<0.001), burning sensation in the pharynx (HR: 2.49; p=0.02), eye irritation (HR: 3.43; p<0.001) and tearing (HR: 4.95; p<0.001). The median time for symptom development was 16 months (95% IQR: 14.8-17.1). Conclusion: Residents exposed to surgical smoke are at greater risk of developing occupational symptoms, with an average time of 16 months for their onset.
