RESUMEN

OBJECTIVE: to identify variables related to pleural complications in patients undergoing tube thoracostomies due to traumatic injuries. METHOD: we conducted a prospective observational study from May/2019 to January/2021 including adult trauma patients submitted to tube thoracostomies after hospital admission. Patients undergoing thoracotomies as the initial treatment were not included. We excluded patients with suspected and confirmed COVID-19 diagnosis during the hospitalization. Pleural complications were defined as clotted hemothorax, residual pneumothorax and empyema. Students t, Mann Whitneys, Chi square and Fishers exact test were used to compare variables between groups. We considered p<0.05 as significant. RESULTS: we analyzed 68 patients. The mean age was 36.0 + 12.6 years and 91.2% were male. The mean RTS and ISS were, respectively, 7.0 ± 1.6 and 15.9 ± 7.6. The most frequent trauma mechanism was stab wounds in 50.0%, followed by blunt trauma in 38.2%. The severity of thoracic injuries was stratified (AIS) as 2 (4.4%), 3 (80.9%), 4 (13.2%), e 5 (1.5%). Pleural complications happened in 14 (20.5%) patients, being clotted / residual hemothorax (11.8%), residual pneumothorax (4.4%), empyema (2.9%) and miscellaneous (1.4%). These patients were treated by thoracoscopy (5), thoracotomy (3), chest re-drainage (3) and clinical measures alone (3). There was a significant association between pleural complications with the time of permanence (p<0,001) and the necessity of relocation (p<0,001) of the drain. CONCLUSION: the predictors of pleural complications in this series were time of permanence and the necessity of relocation of the drain.

RESUMO Objetivo: identificar as variáveis relacionadas às complicações pleurais em vítimas de trauma submetidas a drenagem torácica. Método: estudo observacional prospectivo entre maio/2019 e janeiro/2021, incluindo adultos submetidos a drenagem torácica após a admissão hospitalar para tratamento de lesões traumáticas. Pacientes que desenvolveram COVID19 foram excluídos. As complicações pleurais foram caracterizadas como: pneumotórax residual, hemotórax residual / coagulado e empiema pleural. Comparamos as variáveis coletadas entre os grupos de pacientes com e sem estas complicações. Os testes t de Student, Mann Whitney, Chi quadrado e Fisher foram utilizados para análise estatística. Foram considerados significativos valores de p<0,05. Resultados: analisamos 68 casos, com média etária de 36,0 + 12,6 anos, de RTS de 7,0 ± 1,6 e ISS de 15,9 ± 7,6, sendo 62 (91,2%) do sexo masculino. Trinta e quatro pacientes (50,0%) foram vítimas de ferimento por arma branca. O AIS das lesões torácicas foi classificado como 2 (4,4%), 3 (80,9%), 4 (13,2%), e 5 (1,5%). As complicações pleurais ocorreram em 14 casos (20,5%), sendo hemotórax residual / coagulado em 8 casos (11,8%), pneumotórax residual em 3 (4,4%), o empiema pleural em 2 (2,9%) e associações em 1 (1,4%). Estas complicações foram tratadas por videotoracoscopia (5 casos), toracotomia (3), redrenagem de tórax (3) e medidas clínicas apenas (3). A redrenagem de tórax (p<0,001) e o tempo de permanência do dreno (p<0,001) tiveram relação significativa com a presença de complicações pleurais. Conclusão: a redrenagem do tórax e o maior tempo de permanência do dreno foram associados às complicações pleurais.
