          Abstract

          OBJETIVO: Avaliar a relação entre o uso de vestimenta de proteção radiológica e a diminuição da dose absorvida de radiação ionizante, reforçando a eficácia do seu uso tanto para pacientes quanto para indivíduos ocupacionalmente expostos. MATERIAIS E MÉTODOS: O estudo foi desenvolvido utilizando-se o método de revisão integrativa de literatura, e teve como materiais: 21 artigos, 2 livros, 1 tese, 1 trabalho de conclusão de curso, 1 programa de computador, 4 pesquisas em base de dados (Instituto Brasileiro de Geografia e Estatística e Departamento de Informática do Sistema Único de Saúde) e 2 diretrizes de proteção radiológica. RESULTADOS: A utilização da vestimenta de proteção radiológica, teoricamente, reduz 86% a 99% a dose absorvida. Na prática, a redução nos pacientes pode ser de 88% na radiologia convencional e chegar a 95% no exame tomográfico. Nos indivíduos ocupacionalmente expostos, a redução durante um cateterismo cardíaco é em torno de 90% e durante uma cirurgia ortopédica é de 75%. CONCLUSÃO: Conforme demonstrado em várias pesquisas, o uso de vestimenta de proteção radiológica é eficaz e de baixo custo e reduz a dose desnecessária nos pacientes e nos indivíduos ocupacionalmente expostos. Logo, sua utilização é necessária para a implementação de um efetivo programa de proteção radiológica em um serviço de radiodiagnóstico.

          OBJECTIVE: The present study was aimed at evaluating the relation between the use of radiation protection gear and the decrease in absorbed dose of ionizing radiation, thereby reinforcing the efficacy of its use by both the patients and occupationally exposed personnel. MATERIALS AND METHODS: The integrative literature review method was utilized to analyze 21 articles, 2 books, 1 thesis, 1 monograph, 1 computer program, 4 pieces of database research (Instituto Brasileiro de Geografia e Estatística and Departamento de Informática do Sistema Único de Saúde) and 2 sets of radiological protection guidelines. RESULTS: Theoretically, a reduction of 86% to 99% in the absorbed dose is observed with the use of radiation protection gear. In practice, however, the reduction may achieve 88% in patients submitted to conventional radiology, and 95% in patients submitted to computed tomography. In occupationally exposed individuals, the reduction is around 90% during cardiac catheterization, and 75% during orthopedic surgery. CONCLUSION: According to findings of several previous pieces of research, the use of radiation protection gear is a low-cost and effective way to reduce absorbed dose both for patients and occupationally exposed individuals. Thus, its use is necessary for the implementation of effective radioprotection programs in radiodiagnosis centers.

              Radiation exposure to the hands of orthopaedic surgeons: are we underestimating the risk?

              Previous studies reported that the radiation exposure to the hands of orthopaedic surgeons was far below the acceptable limit. However, the risk could have been underestimated as some factors were overlooked, namely monitoring trainees during average workload, placing dosimeters over the most susceptible locations, measuring the cumulative dosage of radiation and considering the dose limit for non-classified workers. We performed a prospective study in two centres to estimate the radiation dose to the hands of two consultant trauma surgeons and two trainees (one assisting and one operating) while performing 47 fluoroscopy-assisted procedures. We used validated thermoluminescent dosimeters (TLDs) rings and fingerstalls for monitoring the cumulative dosage. Trainees were at higher risk while performing intramedullary nailing and during assistance. Higher radiation doses were recorded from dominant index fingers and particularly fingertips. The risk of radiation exposure appears to be higher than previously reported. Fingertips are more susceptible to radiation exposure and should therefore be monitored in forthcoming studies.
