AbstractDelayed hemothorax (DHTX) is rarely seen. On an 8-year retrospective analysis of blunt thoracic trauma (BTT), hemothorax (HTX) was diagnosed in 167 patients: 18 children, 113 adults, and 36 elderly. No statistical differences were seen in any age groups regarding Injury Severity Score (mean ISS, 30.54), critical care length of stay (CLOS, 9.0), and hospital LOS (HLOS, 11.21). Mortality rate was 18 per cent in adults and 28 per cent in elderly (P value < 0.0001). HTX was acute in 160 and delayed in 7 patients. Two-thirds of HTX patients were males and 75 per cent had rib fractures. All of our DHTX patients were males (5 adults and 2 elderly) and had rib fractures. Acute HTX was seen in younger patients (43.3 vs 56.1 years, P value 0.46), with higher ISS (31.44 vs 14.43, P value < 0.001), CLOS (7.19 vs 3.0 days, P value 0.511) and HLOS (11.9 vs 11.6, P value 0.468). Mortality was 22.5 per cent in AHTX and none in DHTX. Eighty-six per cent of DHTX and 49 per cent of AHTX patients went home on discharge. DHTX was rare (5%) in the current report with lower ISS, HLOS, and no mortality. Patients with rib fractures should be watched for development of DHTX as timely diagnosis and treatment is essential for favorable outcome.
