What color drainage is most consistent with a traumatic hemothorax?

• A. Bloody drainage.
• B. Clear serous drainage.
• C. Purulent drainage.
• D. Yellow-green drainage.

Answer: (A)

In a traumatic hemothorax, blood from injured vessels fills the pleural space, so the chest tube is most likely to drain blood. The earliest drainage is typically bright red and may be clotted, reflecting ongoing bleeding from thoracic injuries. As bleeding is controlled, the fluid can become serosanguinous or clearer, but the presence of actual blood remains the hallmark in this scenario.

Clear serous drainage would suggest non-hemorrhagic pleural fluid or resolved bleeding, not an ongoing hemothorax. Purulent drainage points to infection such as empyema, which is not characteristic of an acute traumatic bleed. Yellow-green drainage often indicates pus or bile-related material, again more aligned with infection or a different pathology rather than a fresh traumatic bleed.
