ABSTRACT

ABSTRACT Objective: to verify the efficiency and usefulness of basic ultrasound training in trauma (FAST - Focused Assessment with Sonography in Trauma) for emergency physicians in the primary evaluation of abdominal trauma. Methods: a longitudinal and observational study was carried out from 2015 to 2017, with 11 emergency physicians from Hospital Universitário do Oeste do Paraná, submitted to ultrasound training in emergency and trauma (USET® - SBAIT). FAST results started to be collected two months after the course. These were compared with a composite score of complementary exams and surgical findings. Information was stored in a Microsoft Excel program database and submitted to statistical analysis. Results: FAST was performed in 120 patients. In the study, 38.4% of the assessed patients had a shock index ≥0.9. The composite score detected 40 patients with free peritoneal fluid, whereas FAST detected 27 cases. The method sensitivity was 67.5%, specificity was 98.7%, the positive predictive value was 96.4%, the negative predictive value was 85.39% and accuracy was 88%. All those with a positive FAST had a shock index ≥0.9. Fifteen patients with positive FAST and signs of instability were immediately submitted to surgery. Conclusions: the basic training of emergency physicians in FAST showed efficiency and usefulness in abdominal trauma assessment. Due to its low cost and easy implementation, this modality should be considered as a screening strategy for patients with abdominal trauma in health systems.


RESUMO Objetivo: verificar a eficiência e a utilidade do treinamento básico em ultrassom no trauma (Focused Assessment with Sonography in Trauma - FAST) para emergencistas, na avaliação primária do trauma abdominal. Métodos: estudo longitudinal, observacional, realizado durante o período de 2015 a 2017, com 11 emergencistas do Hospital Universitário do Oeste do Paraná, submetidos ao treinamento em ultrassom na emergência e trauma (USET® - SBAIT). Resultados dos FAST começaram ser coletados dois meses após o curso. Estes foram comparados com escore composto de exames complementares e achados cirúrgicos. Informações foram armazenadas em banco de dados do programa Microsoft Excel® e submetidas à análise estatística. Resultados: foram realizados FAST em 120 pacientes. No estudo, 38,4% dos pacientes avaliados apresentavam índice de choque ≥0,9. O escore composto detectou 40 pacientes com líquido livre peritoneal. FAST detectou 27 casos de líquido livre peritoneal. A sensibilidade do método foi de 67,5%, a especificidade de 98,7%, o valor preditivo positivo de 96,4%, o valor preditivo negativo de 85,39% e a acurácia foi de 88%. Todos que tiveram FAST positivo apresentavam índice de choque ≥0,9. Quinze pacientes com FAST positivo e sinais de instabilidade foram conduzidos imediatamente para cirurgia. Conclusões: o treinamento básico de emergencistas em FAST demonstrou eficiência e utilidade na avaliação do trauma abdominal. Por seu baixo custo e facilidade de implantação, esta modalidade deve ser considerada como estratégia de triagem de pacientes com trauma abdominal nos sistemas de saúde.
