First Aid for Deep Arm Laceration in Children: Emergency Steps

1. Call 911 immediately—this is a medical emergency.
2. Apply direct pressure with clean cloth/gauze. Do NOT remove once applied (may dislodge clot).
3. Elevate the arm above heart level to reduce bleeding and swelling.
4. Keep the child calm and still to prevent further injury and aid responders.

Do not apply tourniquet unless trained and bleeding is life-threatening. Let EMS manage advanced care.
