Root Cause

Tourniquets must be placed 2-3 inches proximal to the wound, never directly over a joint, as joint anatomy prevents effective compression and risks nerve/vascular damage.

generic

中文

止血带必须放置在伤口近端2-3英寸处，绝不能直接放在关节上，因为关节解剖结构妨碍有效压迫并可能损伤神经/血管。

Workarounds

  1. 90% success Place tourniquet 2-3 inches proximal to the wound, above the joint if possible. For elbow bleeds, apply to upper arm; for knee bleeds, apply to upper thigh. Tighten until bleeding stops. Document time of application.

  2. 75% success If tourniquet cannot be placed proximal to joint (e.g., wound at joint itself), use hemostatic gauze with direct pressure and consider junctional tourniquet device (e.g., SAM Junctional) if available.

Dead Ends

Common approaches that don't work:

  1. Apply tourniquet directly over the bleeding joint to stop blood flow at the injury site 95% fail

    Joint movement and irregular bone structure prevent adequate compression; tourniquet may slip or fail to occlude artery.

  2. Place tourniquet below the joint to avoid interfering with joint function 85% fail

    Venous and arterial flow may not be fully occluded; bleeding from proximal wound may continue.

  3. Use a wide bandage instead of a tourniquet for joint bleeds 70% fail

    Direct pressure alone is insufficient for arterial bleeding from joint; tourniquet is indicated for life-threatening hemorrhage.
