根因分析
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。
English
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.
官方文档
https://www.stopthebleed.org/tourniquet-placement/解决方案
-
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.
-
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.
无效尝试
常见但无效的做法:
-
Apply tourniquet directly over the bleeding joint to stop blood flow at the injury site
95% 失败
Joint movement and irregular bone structure prevent adequate compression; tourniquet may slip or fail to occlude artery.
-
Place tourniquet below the joint to avoid interfering with joint function
85% 失败
Venous and arterial flow may not be fully occluded; bleeding from proximal wound may continue.
-
Use a wide bandage instead of a tourniquet for joint bleeds
70% 失败
Direct pressure alone is insufficient for arterial bleeding from joint; tourniquet is indicated for life-threatening hemorrhage.
