The impact of a chest tube management protocol on the outcome of trauma patients with tube thoracostomy / Impacto de um protocolo de cuidados a pacientes com trauma torácico drenado

ABSTRACTObjective:to investigate the effect of standardized interventions in the management of tube thoracostomy patients and to assess the independent effect of each intervention.Methods:A chest tube management protocol was assessed in a retrospective cohort study. The tube thoracostomy protocol (TTP) was implemented in August 2012, and consisted of: antimicrobial prophylaxis, chest tube insertion in the operating room (OR), admission post chest tube thoracostomy (CTT) in a hospital floor separate from the emergency department (ED), and daily respiratory therapy (RT) sessions post-CTT. The inclusion criteria were, hemodynamic stability, patients between the ages of 15 and 59 years, and injury severity score (ISS) < 17. All patients had isolated injuries to the chest wall, lung, and pleura. During the study period 92 patients were managed according to the standardized protocol. The outcomes of those patients were compared to 99 patients treated before the TTP. Multivariate logistic regression analysis was performed to assess the independent effect of each variable of the protocol on selected outcomes.Results:Demographics, injury severity, and trauma mechanisms were similar among the groups. As expected, protocol compliance increased after the implementation of the TTP. There was a significant reduction (p<0.05) in the incidence of retained hemothoraces, empyemas, pneumonias, surgical site infections, post-procedural complications, hospital length of stay, and number of chest tube days. Respiratory therapy was independently linked to significant reduction (p<0.05) in the incidence of seven out of eight undesired outcomes after CTT. Antimicrobial prophylaxis was linked to a significant decrease (p<0.05) in retained hemothoraces, despite no significant (p<0.10) reductions in empyema and surgical site infections. Conversely, OR chest tube insertion was associated with significant (p<0.05) reduction of both complications, and also significantly decreased the incidence of pneumonias.Conclusion:Implementation of a TTP effectively reduced complications after CTT in trauma patients.

RESUMOObjetivo:avaliar a implantação do Cuidado Padronizado com o Dreno de Tórax (CPDT) em um hospital público, referência para o trauma, e o impacto independente de cada um dos itens do protocolo no período do estudo sobre desfechos selecionados.Métodos: coorte retrospectiva avaliando implementação do Cuidado Padronizado para o Dreno de Tórax (CPDT). Foram incluídos pacientes entre 15 e 59 anos de idade, hemodinamicamente estáveis, com Injury Severity Score inferior a 17, com lesão isolada na parede do tórax, pulmão e pleura. Foram comparados 99 pacientes antes do CPDT com 92 depois do CPDT. Foi realizada comparação de desfechos selecionados por meio de diferença de proporções. A regressão logística multivariada foi feita para análise do efeito independente de cada variável do protocolo.Resultados:não houve diferença entre os grupos quanto às variáveis sociodemográficas, índice de gravidade e mecanismo de trauma. A implementação do CPDT resultou no aumento no percentual de todos os itens do protocolo. Houve redução significativa (p<0,05) de hemotórax retido, empiema, pneumonia, infecções de ferida operatória e nova operação, queda do percentual de pacientes retornados com complicações, tempo de internação e de permanência do dreno. A fisioterapia revelou-se independentemente associada à redução de sete dos oito desfechos (p<0,05). O antibiótico presuntivo revelou tendência de associação com a redução de empiema e de infecções de ferida operatória (p<0,10) e esteve associado à redução do hemotórax retido (p<0,05). A drenagem no centro cirúrgico esteve associada à redução de empiema, pneumonia e infecção de ferida operatória (p<0,05).Conclusão:a implementação do CPDT foi efetiva na redução de complicações de pacientes com dreno de tórax.

Ascite quilosa traumática / Traumatic chylous ascites

Chylous ascites is a rare clinical entity. In infancy it is less commom still. The etiology of most of them is usually congenital or idiopathic; trauma is a less frequent cause. It has been implicated in about 10 percent of all cases 1-5. There have been less than one hundred cases published in the English literature, including 12 in children. We report a pediatric case of chylous ascites as a result of blunt abdominal trauma managed by ligation of the lymphatic leak.
