RADIATION EXPOSURE DURING SPINE SURGERY USING C-ARM FLUOROSCOPY.

Abstract:

Objective:To evaluate the radiation dose received by staff in spine surgeries, including those who are not considered occupationally exposed workers. Methods:All spinal surgeries performed in the same department during a period of 12 months were evaluated with regard to the exposure of surgeons, scrub nurses, and auxiliary personnel working in the operating room to radiation from C-arm fluoroscopy. Radiation was measured by 15 film badge dosimeters placed on the professionals' lapels, gloves, and room standardized sites. The films were analyzed in the dosimetry laboratory by collections per period. Results:During the 12 months, 81 spinal surgeries were performed by the same team, with surgical times ranging from 1 to 6 hours. The total radiation dose ranged from 0.16 mSv to 2.29 mSv depending on the dosimetry site. The most exposed site was the wrist of the main surgeon. Conclusion:The results showed that in the spinal surgeries in our setting, the radiation doses are low and within legal limits. Nevertheless, constant training of professionals is essential for radiation protection of medical staff and patients. Level of evidence I/b, exploratory cohort study. Objetivo:Avaliar a dose de radiação recebida pela equipe cirúrgica em cirurgias de coluna, incluindo entre aqueles que não são considerados trabalhadores com exposição ocupacional. Método:Todas as cirurgias de coluna realizadas num mesmo departamento num período de 12 meses foram avaliadas quanto à exposição dos cirurgiões, enfermeiros/instrumentadores e auxiliares trabalhando na sala cirúrgica à radiação do fluoroscópio tipo “C-arm”. A radiação foi medida por 15 dosímetros de filme posicionados nas lapelas, luvas dos profissionais e também em pontos padronizados da sala. Os filmes foram analisados no laboratório de dosimetria em coleções por período. Resultados:Durante 12 meses, 81 cirurgias de coluna foram realizadas pela mesma equipe, e cada cirurgia durou entre 1 e 6 horas. A dose total de radiação variou de 0,16 mSv a 2,29 mSv dependendo do local de mensuração. O local com maior exposição foi o punho do cirurgião principal. Conclusão:Os resultados mostraram que nas cirurgias de coluna no nosso serviço, as doses de radiação foram baixas e dentro dos limites legais. Porém, o treinamento dos profissionais é essencial para a proteção contra a radiação dos profissionais de saúde e seus pacientes. Nível de evidência I/b, estudo de coorte exploratório.
