Abstract ABSTRACTObjective:to analyze the associated factors with empyema in patients with post-traumatic retained hemothorax.Methods:prospective observational study. Data were collected in patients undergoing PD during emergency duty. Variables analyzed were age, sex, mechanism of injury, side of the chest injury, intrathoracic complications of RH, laparotomy, specific injuries, rib fractures, trauma scores, days to diagnosis, diagnostic method of RH, primary indication of PD, initial volume drained, length of the first tube removal, surgical procedure. Cumulative incidence of empyema, pneumonia and pulmonary contusion and the proportion of patients with empyema or without empyema in each category of each variable analyzed were obtained.Results: the cumulative incidence of PD among trauma patients was 1.83% and the RH among those with PD was 10.63%. There were 20 cases of empyema (32.8%). Most were male in the age from 20 to 29, victims of injury by firearm on the left side of the thorax. The incidence of empyema in patients with injury by firearms was lower compared to those with stab wound or blunt trauma; higher among those with drained volume between 300 and 599 ml. The median hospital lenght of stay was higher among those with empyema.Conclusion:the incidence of PD was 1.83% and RH was 10.63%, these results are consistent with the low severity of the patients involved in this study and consistent with the literature. The incidence of empyema proved to be negatively associated with the occurrence of injury by firearms and positively associated with a drained volume between 300 and 599 ml, compared with lower or higher volumes. RESUMOObjetivo:analisar os fatores associados ao empiema em pacientes com hemotórax retido pós-traumático.Métodos:estudo prospectivo observacional. Os dados foram coletados de pacientes submetidos à drenagem pleural de emergência. Foram analisadas: idade, sexo, mecanismo de trauma, lado da lesão torácica, complicações intratorácicas decorrentes do hemotórax retido, laparotomia, lesões específicas, fratura de arcos costais, índices de trauma, dias até o diagnóstico, método diagnóstico do HR, indicação primária da drenagem pleural, volume inicial drenado, dias de permanência do primeiro dreno, procedimento cirúrgico. Obteve-se a incidencia acumulada de empiema, pneumonia e contusão pulmonar e a incidência de empiema em cada categoria das variaìveis analisadas.Resultados:a incidência acumulada de drenagem pleural por trauma foi 1,83% e a de hemotórax retido entre aqueles com derrame pleural foi de 10,63%. Houve 20 casos de empiema (32,8%). A maioria tinha entre 20 e 29 anos, era do sexo masculino e sofreu ferimento por arma de fogo. A incidência de empiema entre pacientes com ferimento por arma de fogo foi inferior aos demais mecanismos; superior entre aqueles com volume drenado entre 300 e 599 ml. O tempo mediano de permanência hospitalar foi maior nos pacientes com empiema.Conclusão:as incidências de derrame pleural e hemotórax retido entre aqueles com DP nessa amostra de baixa gravidade dos pacientes foram, respectivamente, 1,83% e 10,63%. A incidência de empiema revelou-se negativamente associada à ocorrência de ferimento por arma de fogo e positivamente associada a volume drenado entre 300 e 599 ml, bem como, ao tempo mediano de permanência hospitalar.
