Management of Persistent Bleeding in Extremities
Direct manual pressure is the immediate first-line intervention for all extremity bleeding, and if this fails to control life-threatening hemorrhage, a commercial tourniquet should be applied and tightened until bleeding stops. 1
Initial Hemorrhage Control
Direct Manual Pressure (First-Line)
- Apply firm, continuous direct manual pressure over the bleeding site using gauze or clean cloth—this is the most effective initial intervention for hemorrhage control 1, 2
- Maintain pressure for sufficient duration; the amount of pressure and duration are the most critical factors for successful bleeding cessation 2, 3
- If bleeding continues, add more gauze on top without removing the initial layer 2
- Do not waste time with pressure points (brachial/femoral artery compression)—these are ineffective and delay proper treatment 1, 2
- Do not rely on limb elevation alone as a hemorrhage control method 2
Hemostatic Dressings (Adjunctive Therapy)
- If direct pressure alone is insufficient, add a hemostatic dressing to improve effectiveness 1, 2
- Hemostatic dressings (containing materials that promote clotting) result in higher rates of bleeding cessation within 5 minutes (51.2%) compared to direct pressure alone (32.5%) 1
- These dressings shorten time to hemostasis compared to standard gauze 2, 4
- Apply the hemostatic dressing directly to the wound with continued direct pressure for 3 minutes 5
Pressure Dressings (Maintenance)
- Once bleeding has stopped with direct pressure, apply a pressure dressing to maintain hemorrhage control 1, 2
- Wrap an elastic bandage firmly over gauze to hold it in place with sustained pressure if continuous manual pressure cannot be maintained 2
- Commercial pressure dressings and elastic adhesive dressings are effective when applied by trained personnel 1
Tourniquet Application for Life-Threatening Bleeding
When to Apply a Tourniquet
Apply a tourniquet only when direct pressure (with or without hemostatic dressings) fails to control life-threatening extremity bleeding 1, 2
Life-threatening bleeding is recognized by:
- Pooling of blood on the ground 1
- Continued arterial spurting despite direct pressure 1
- Mangled extremity injuries, penetrating wounds, blast injuries, or traumatic amputations 1
Proper Tourniquet Technique
- Use a commercial tourniquet—these are superior to improvised tourniquets 1, 2
- If an improvised tourniquet must be used, ensure it is at least 2 inches wide to minimize tissue damage and pain 1
- Narrow tourniquets cause more pain, tissue damage, and are less effective than wider tourniquets 1
- Apply the tourniquet proximal to the wound and tighten until bleeding completely stops 1
- Document the exact time of tourniquet application and communicate this to all healthcare providers 6, 2
Tourniquet Duration and Removal
- Leave the tourniquet in place until surgical control of bleeding is achieved, but minimize this time as much as possible 1, 6
- Some guidelines suggest a maximum application time of 2 hours, though military data shows extremity survival with up to 6 hours of tourniquet time 1, 6
- Prolonged or improper tourniquet placement can cause nerve paralysis and limb ischemia 1, 6
- Consider removing the tourniquet after applying a hemostatic dressing with direct pressure if hemorrhage control is maintained 5
Adjunctive Measures
Local Cold Therapy
- Apply ice packs to the wound area to help control bleeding 2
- This is useful as an adjunctive measure alongside direct pressure 2
Mechanical Pressure Devices
- Consider mechanical pressure devices (pressure bandages) when direct manual pressure is not feasible, such as in mass casualty events 1
- These devices may be useful when there are insufficient resources to provide continuous direct pressure to all victims 1
Critical Pitfalls to Avoid
- Do not delay tourniquet application if direct pressure fails—blood loss from major arterial injury can cause exsanguination and death in 3-5 minutes 3
- Do not apply tourniquets to the neck, thorax, or abdomen—circumferential compression in these areas can occlude the airway, restrict chest expansion, or prevent adequate respiration 3
- Do not remove initial gauze layers when adding more—this disrupts clot formation 2
- Do not use narrow improvised tourniquets—they require higher pressure, cause more pain, and increase risk of nerve injury 1
- Minimize time from injury to definitive hemorrhage control (surgery or embolization)—every minute of delay increases mortality 1
Special Considerations
Hemostatic Dressings with Tourniquets
- Hemostatic dressings can reduce tourniquet time while maintaining hemorrhage control 5
- After tourniquet application achieves hemostasis, apply a hemostatic dressing with direct pressure for 3 minutes, then attempt tourniquet removal 5
- If bleeding recurs after tourniquet removal, immediately reapply the tourniquet 5
