ABSTRACT

Introducción: Una cuarta parte de las muertes en trauma son por trauma torácico. El paciente con trauma torácico generalmente presenta neumotórax o hemotórax, los cuales predisponen a complicaciones infecciosas que dependen de múltiples factores. El manejo en muchas instituciones incluye antimicrobianos para prevenir complicaciones infecciosas, si bien no está demostrada la reducción de la incidencia de infecciones. El objetivo de nuestra investigación fue evaluar la utilidad de los antimicrobianos en trauma torácico. Material y métodos: Estudio clínico controlado, doble ciego, analítico, longitudinal, prospectivo, comparativo, de dos grupos: A recibió cefalotina y B, placebo. Rango de edad de 15 a 65 años. El análisis estadístico se llevó a cabo con χ2 o prueba exacta de Fisher. Resultados: 126 pacientes fueron incluidos en el estudio, 63 en cada grupo, con similares características demográficas. La media de días con pleurostomía fue de 6.56, pero en quienes desarrollaron empiema fue de 11; la incidencia del empiema fue de 6.4 % (n = 8). Tres pacientes con empiema fueron del grupo A y cinco del B; tres empiemas fueron complejos y cinco simples; dos requirieron toracoscopia y uno toracotomía; cinco curaron con sonda endopleural. Al relacionar en el análisis bivariado el uso de antimicrobiano versus empiema y días de estancia, no se identificó diferencia estadísticamente significativa. Conclusiones: Este estudio no demostró que los antimicrobianos sean útiles para prevenir infecciones pleurales en trauma torácico.


BACKGROUND: Thoracic trauma accounts for 25% of deaths due to trauma. Chest trauma patients generally present to the emergency room with pneumo- or hemothorax. According to the majority of the studies, management of closed thoracostomy for trauma includes the use of antimicrobial drugs to prevent infectious complications, but this has not been proven to be beneficial. We undertook this study to evaluate antimicrobial use in thoracic trauma patients with closed thoracostomy and its impact on the development of infectious complications. METHODS: We carried out a prospective, randomized, double blind, comparative study. Patients with isolated chest trauma requiring closed thoracostomy were divided into two groups. Group A received cefalotin, and group B received placebo. Ages ranged from 15-65 years. Results were analyzed with chi(2) and Fisher exact test. RESULTS: One hundred twenty six patients were included in this study. There were 63 patients in each group with similar demographic characteristics. The mean length of hospital stay with the tube was 6.56 days, but the average stay was 11 days for patients who developed empyema. Eight patients developed empyema, three patients with empyema belonged to group A patients and five patients with empyema belonged to group B. For empyema management, five cases were resolved by chest drainage, two cases required thoracoscopic cleaning and drainage and one patient was resolved with thoracotomy and pleural decortication. Bivariate analysis comparing antimicrobial use vs. empyema and length of drainage vs. antimicrobials did not show a statistically significant difference. CONCLUSIONS: The present study did not demonstrate that antimicrobial use was beneficial in the prevention of pleural infections in the management of chest trauma patients requiring closed thoracostomy.
