Management of Hemothorax After Blunt Chest Trauma: Results from a Level II Emergency Department

Background: Traumatic hemothorax is a common complication of blunt chest trauma and remains associated with significant morbidity and mortality. Although contrast-enhanced computed tomography (CT) is central to diagnosis, the optimal criteria for selecting patients who require invasive management versus conservative treatment remain unclear. This study aimed to evaluate the management strategies and clinical outcomes of traumatic hemothorax and to identify predictors of surgical intervention and postoperative complications. Methods: We conducted a retrospective, single-center cohort study including adult patients admitted to a Level II Emergency Department with hemothorax following blunt chest trauma between January 2019 and December 2024. Primary outcomes were the need for urgent chest drainage or surgery. Secondary outcomes included postoperative complications, length of hospital stay, and intensive care unit admission. Univariable and multivariable regression analyses were performed to identify factors associated with surgical intervention and complications. Results: Seventy-two patients were included (mean age 60.0 ± 20.5 years; 80.6% male). Rib fractures were the most common cause of hemothorax (61.1%). Chest tube placement was required in 70.8% of cases, and 31.9% underwent urgent surgical intervention. Active bleeding on contrast-enhanced CT was identified in 16.7% of patients and was the only independent predictor of urgent surgery (OR 3.85, 95% CI 1.07–13.88; p = 0.039). The initial volume of blood drained after chest tube insertion did not differ between surgically and non-surgically managed patients. Conservative management was successful in 19.4% of cases. Postoperative complications occurred in five patients and were associated with a higher comorbidity burden. Overall mortality was 5.6%. Conclusions: In traumatic hemothorax following blunt chest trauma, active bleeding on contrast-enhanced CT seems to be the strongest predictor of urgent surgical intervention, whereas initial pleural drainage volume alone is not. Conservative management is safe in selected patients, while comorbidities influence postoperative outcomes. Multidisciplinary management and accurate radiological assessment are essential to guide timely and appropriate treatment.
