First Aid for Deep Lacerations: Applying a Pressure Bandage to Control Bleeding

Priority: Stop the Bleeding

A pressure bandage is the standard first-aid choice for a deep, actively bleeding laceration (e.g., under the arm near the axilla).

Step-by-Step Application

1. Safety – Ensure scene is safe.
2. Direct Pressure – Remove loose debris; place sterile dressing on wound; pack deep wounds with gauze. Apply firm hand pressure.
3. Wrap Pressure Bandage – Start distal (wrist), wrap upward covering forearm, elbow, and upper arm, encircling the wound. Snug but not tourniquet-tight (check capillary refill).
4. Secure – Clips, tape, or tuck end.
5. Cover – Clean dressing over bandage.
6. Elevate – Arm above heart level if possible.
7. Seek Professional Care – Deep axillary lacerations risk neurovascular injury; urgent surgical evaluation needed.

Key Reminders

• Do not remove soaked dressings—add more on top.
• Monitor distal pulse, color, sensation.
• Tourniquet only as last resort for life-threatening limb hemorrhage.
