Factors Affecting Mortality in Blunt Thoracic Trauma

Abstract

Blunt thoracic trauma is usually associated with extra-thoracic injuries, but the effect of blunt thoracic trauma on mortality is not known. Patients with blunt thoracic trauma were evaluated with regard to clinical findings and factors affecting mortality. There were 76 patients (37.2±15 years) in the study group. Traffic accidents (63%) were the most common cause of trauma. Pneumothorax (54%), rib fracture (42%), hemothorax (22%) and lung contusion (22%) were common thoracic injuries. Extra-thoracic injuries were most commonly seen in the extremities (46%) and abdomen (40%). Glasgow Coma, Injury Severity and Revised Trauma Scores were 14±2.6, 19±13 and 7.4±1.5, respectively. Non-operative management was effective in 37 (48.7%) patients, tube thoracotomy and thoracotomy were performed in 37 (48.7%) and 2 (2.6%) patients, respectively. Mortality rate was 10.5%. Systolic blood pressure lower than 90 mmHg and superficial and apneic respiration at the first admission, and values of trauma scoring systems were significantly associated with mortality (p<0.05). The effect of thoracic trauma on mortality with regard to thoracic pathology is not shown, although it is usually associated with extra-thoracic injuries. There was a close relationship between the pattern of respiration, values of systolic blood pressure and trauma scoring systems, and mortality. Non-operative management and tube thoracotomy were effective in most of the cases.
