How to Pack a Wound: A Step-by-Step Guide

This article is for general education. It is not a substitute for hands-on training — wound packing is a hands-on skill best learned in a certified course such as Stop the Bleed.

Wound packing comes up whenever a wound is in a location a tourniquet can't reach — the neck, groin, or high on the torso — or when bleeding is severe enough that direct pressure alone isn't controlling it. It's a different technique from applying a bandage, and it takes some nerve the first time, since it means physically packing gauze into an open wound.

Why Packing Works

A wound bleeds because the space inside it isn't under enough pressure to let clotting take hold. Packing gauze directly into the wound cavity fills that space and creates continuous pressure against the bleeding vessel from the inside out, which a surface bandage alone can't do for a deep wound.

The General Steps

1. Expose the wound. Cut away clothing with trauma shears if needed — you need to see what you're working with.
2. Locate the source. Find the specific point the bleeding is coming from, not just the general area.
3. Pack directly into the wound. Using gauze (hemostatic gauze if available), press it firmly into the wound cavity, working from the deepest point outward, maintaining constant pressure with one hand while packing with the other.
4. Keep packing. Continue until the wound cavity is completely filled — this often takes more gauze than people expect.
5. Apply a pressure dressing. Once packed, secure everything with an emergency trauma dressing, wrapped tightly enough to maintain constant pressure on the packed wound.
6. Hold pressure. Maintain direct pressure on the dressing for at least 3 minutes, or until bleeding is controlled.

Hemostatic vs. Standard Gauze

Standard gauze works through packing and pressure alone. Hemostatic gauze, like ChitoSAM, adds an active clotting agent to the mix, which can speed up bleeding control in severe cases. For most situations either works, but hemostatic gauze is worth having in a kit for the worst-case scenario.

Common Mistakes

• Not packing enough gauze. The instinct is to under-pack; the wound cavity needs to be genuinely full, not lightly filled.
• Losing pressure while switching gauze rolls. Keep constant pressure on the wound throughout, even while reaching for more material.
• Wrapping too loosely. The pressure dressing needs to be tight enough to matter — a loose wrap defeats the purpose.

Practice Before You Need It

Reading about wound packing and doing it under stress are very different experiences. If you're building a kit around this skill, consider a hands-on Stop the Bleed course, and practice with training gauze so the motion feels familiar if you ever need it for real.
