SCF ENCYCLOPEDIA ENTRY

MASSIVE HEMOTHORAX

Alternative Terminology

• Massive Traumatic Hemothorax
• Major Pleural Hemorrhage Syndrome
• Catastrophic Hemothorax
• Severe Intrapleural Hemorrhage
• Exsanguinating Hemothorax
• Thoracic Hemorrhagic Compartment Syndrome

1. SCOPE & POSITIONING

Etiology / Classification

Massive Hemothorax is a life-threatening thoracic emergency characterized by rapid accumulation of a large volume of blood within the pleural cavity, resulting in lung compression, respiratory failure, circulatory collapse, hemorrhagic shock, and high mortality risk.

Clinically, massive hemothorax is traditionally defined as:

• Initial chest tube drainage exceeding approximately 1,500 mL of blood

or

• Persistent hemorrhage exceeding approximately 200–250 mL/hour for several consecutive hours

although physiologic instability often supersedes absolute volume criteria.

Within the SCF framework, Massive Hemothorax is classified as a Thoracic Hemorrhagic Compartment Failure Syndrome involving catastrophic disruption of pleural vascular integrity, pulmonary expansion systems, oxygen transport networks, and cardiopulmonary homeostasis mechanisms.

18. SCF LAYMAN’S SUMMARY

Massive Hemothorax is a life-threatening emergency in which a large amount of blood rapidly accumulates inside the chest cavity around the lung. The condition is most commonly caused by severe chest trauma but can also occur after certain medical procedures or from major blood vessel injuries.

As blood fills the pleural space, the affected lung becomes compressed and cannot expand properly, making breathing increasingly difficult. At the same time, significant blood loss can lead to shock, organ failure, and death if not treated immediately.

Treatment typically requires emergency chest tube placement, aggressive blood transfusion, intensive care support, and often urgent surgery to identify and stop the source of bleeding. Rapid recognition and intervention are essential for survival.
