What is the primary objective of hemorrhage control in Tactical Combat Casualty Care (TCCC), and which device is first-line for severe extremity bleeding?

• A. To prevent exsanguination by rapidly stopping life-threatening bleeding; the first-line device is a tourniquet.
• B. To minimize pain before bleeding is stopped; the first-line device is a tourniquet.
• C. To stabilize the limb for transport; the first-line device is a splint.
• D. To maintain blood pressure with no device; the first-line device is a chest seal.

Answer: (A)

Stopping life-threatening bleeding quickly to prevent exsanguination is the core goal of hemorrhage control in Tactical Combat Casualty Care. In the field, uncontrolled hemorrhage is the leading preventable cause of death, so the priority is to stop the bleed as fast as possible to keep the patient alive long enough to reach definitive care.

For severe extremity bleeding, a tourniquet is the first-line device because it rapidly halts arterial blood flow, is effective in most cases, and can be applied even when access to the wound is difficult. Splints help with limb stabilization after bleeding is controlled, and chest seals address chest injuries, but they do not replace the need to stop life-threatening limb bleeding with a tourniquet.
