How to Pack a Wound
Wound packing works on a simple principle: in a deep wound, the bleeding artery sits well below the skin, and the only way to stop it is to apply pressure at the source. You do that by stuffing gauze tightly into the cavity until it is completely filled, then holding firm pressure to let a clot form against the packed gauze.
Plain vs. hemostatic gauze
| Type | Best for |
|---|
| Plain rolled gauze | Wound packing where hemostatic agents aren't required or available; high-volume training |
| Hemostatic gauze | High-flow junctional and deep bleeds where faster clotting is critical |
Technique
- Find the source — clear pooled blood and locate where it's actively bleeding.
- Pack tight, to the bottom — press gauze directly onto the vessel and keep feeding it until the cavity is packed firm.
- Hold pressure at least three minutes — longer for hemostatic gauze per its instructions.
- Secure — wrap a pressure dressing over the packing to hold it for transport.
Wounds over the chest and abdomen are not packed the same way — junctional and extremity wounds are the packing targets. Train the technique before you need it.
Stocking a trauma kit? Carry both plain and hemostatic gauze, plus a pressure dressing to secure the pack. Anchor your loadout with the

Frequently Asked Questions
When do you pack a wound instead of using a tourniquet?
Pack a wound when bleeding is in a location a tourniquet can't address, such as the groin, armpit, neck, or a deep extremity wound where a tourniquet isn't an option. Packing drives pressure directly onto the deep bleeding vessel.
What is the difference between plain and hemostatic packing gauze?
Plain rolled gauze fills the cavity and applies mechanical pressure; hemostatic gauze adds a clotting agent for faster control of high-flow bleeds. Both are packed the same way, to the source and held under pressure.
How do you pack a wound correctly?
Locate the bleeding source, then press gauze directly onto it and keep feeding gauze until the wound cavity is packed firm. Hold direct pressure for at least three minutes, then secure with a pressure dressing.
How much gauze does it take to pack a wound?
A deep junctional wound can take an entire roll or more. Field kits often carry multiple packs, and training on a packing trainer shows how much gauze a realistic cavity actually requires.
Can you pack a chest or abdominal wound?
Packing is for junctional and extremity wounds. Open chest wounds are managed with a chest seal, and abdominal evisceration has its own management. Train on which wounds are packing targets before relying on the technique.
