Wound Packing for Deep Junctional & Cavity Wounds

Wound packing is the standard intervention for life-threatening haemorrhage from wounds where a tourniquet cannot be applied — the groin, axilla (armpit), neck, and deep cavity wounds such as gunshot or stab wounds to the torso. It involves filling the wound cavity completely with gauze and applying sustained, direct pressure to tamponade bleeding from within the wound itself.

This technique was once the exclusive domain of military combat medics. It is now taught in civilian Stop the Bleed training courses because the same injuries that occur in combat — gunshots, stabbings, and blast injuries — occur in public spaces. A bystander who knows how to pack a wound can save a life before emergency services arrive.

When Wound Packing Is Required

Wound Type	Tourniquet Applicable?	Intervention
Femoral artery injury (groin)	No — too proximal for limb tourniquet	Wound packing + junctional pressure
Axillary artery injury (armpit)	No	Wound packing + bandage compression
Penetrating neck trauma	No	Direct pressure (see next article)
Deep stab wound to thigh	Sometimes — tourniquet if applicable	Wound packing if too proximal
Gunshot wound to torso (abdomen/chest)	No	Wound packing for penetrating wound
Deep cavity wound, no active arterial spurting	No tourniquet applicable	Wound packing
Amputated limb (clean cut)	Yes	Tourniquet first

⚠️ Wound packing is a temporary life-saving measure. Every patient who has had a wound packed requires urgent surgical evaluation. Packing controls bleeding; it does not treat the underlying injury.

Haemostatic Gauze — What It Is and Why It Works

Haemostatic gauze is standard surgical gauze impregnated with a clot-activating agent. When packed into a bleeding wound, it concentrates clotting factors at the bleeding site and triggers a more rapid and robust clot formation than uncoated gauze.

The two most widely available products are:

QuikClot Combat Gauze (Z-Fold)

• Active ingredient: kaolin (inorganic mineral that activates clotting cascade)
• Endorsed by the US military's Committee on Tactical Combat Casualty Care (TCCC)
• Produces a firm clot within 3–5 minutes of sustained pressure
• X-ray detectable stripe woven into gauze (prevents surgical retention errors)
• Holds pressure well; relatively easy to pack

Celox Gauze

• Active ingredient: chitosan (derived from shellfish shells)
• Works by directly aggregating red blood cells regardless of clotting pathway
• Effective in patients on anticoagulants (warfarin, heparin) — where kaolin-based agents are less effective
• Important for elderly patients and those with known clotting disorders

Plain gauze — significantly less effective but far better than doing nothing. If no haemostatic gauze is available, plain sterile (or clean) gauze should be used.

Wound Packing Technique — Step by Step

Before You Begin

1. Protect yourself — put on gloves if available. If not, use a plastic bag, garment, or any barrier available. Proceed regardless if there is no option.
2. Expose the wound — cut or remove clothing. You need to see the entire wound.
3. Identify the wound cavity — is it a deep tunnel (stab/gunshot)? A gaping laceration? A groin/armpit wound? The technique adapts slightly to wound geometry.
4. Tell the patient what you are doing — packing is painful. Warn them: "This is going to hurt but it will save your life."

The Packing Process

1. Open the haemostatic gauze — do not contaminate it unnecessarily, but sterility is secondary to speed in a life-threatening bleed
2. Locate the deepest part of the wound — this is where you begin
3. Pack from the bottom up — push gauze into the deepest point of the wound cavity first, using your gloved finger or the handle of a clean instrument
4. Packing, not stuffing — use your index finger to push each fold of gauze firmly into the wound in a controlled, sequential manner. Stuffing gauze loosely on top of the opening does not stop bleeding.
5. Fill completely — continue packing fold by fold until the wound cavity is full and gauze is level with the skin surface. Use the entire roll if necessary.
6. Apply direct pressure — hard and sustained — place both hands (one on top of the other) over the packed wound and press down with your full body weight. Hold for a minimum of 3 minutes — 5 minutes for haemostatic gauze involving arterial sources, 10 minutes for plain gauze
7. Do not lift to check — the temptation to peek breaks the clot forming. Set a timer and hold pressure without interruption.

After Packing

1. Secure the gauze — apply a pressure bandage over the packed wound to maintain compression without requiring you to hold it continuously
2. Reassess — check whether blood is soaking through the bandage. If so, add more gauze and pressure on top — do not remove the existing pack
3. Position — if abdominal wound, lay the patient flat. If torso, semi-reclined may reduce respiratory distress
4. Monitor for shock — pallor, cold extremities, rapid breathing, altered consciousness

Improvised Materials for Wound Packing

In a resource-limited situation where commercial gauze is unavailable:

Material	Effectiveness	Notes
Sterile wound dressing (from first-aid kit)	Good	Unroll and pack in folds
Clean cloth (T-shirt, towel)	Acceptable	Cut into strips; pack systematically
Sanitary towels/pads	Reasonable	Highly absorbent; not designed for cavity packing but better than nothing
Tissue paper	Poor	Disintegrates; use only if truly nothing else available
Dirty cloth	Last resort	Infection risk is secondary to haemorrhage; use it

The principle is the same regardless of material: fill the cavity from the bottom up, then apply sustained direct pressure.

Psychological Aspects of Wound Packing

Packing a deep wound is emotionally and physically demanding. The first-time responder should be mentally prepared:

• Pain response from the patient — wound packing causes significant pain in conscious patients. A patient who screams or tries to pull away is not an indication to stop.
• Appearance of the wound — deep wounds with significant blood pooling are visually distressing. Focus on the technique, not the appearance.
• Blood on your hands — literal and figurative. Gloves reduce this but do not eliminate it.
• "Am I hurting them?" — yes. You are also saving their life.
• Holding pressure is harder than it looks — full-body-weight sustained pressure for 3–10 minutes is physically tiring. Get into a stable kneeling position before you start.

Common Mistakes

1. Stuffing gauze loosely — loose gauze absorbs blood but does not tamponade the bleeding vessel
2. Not packing deep enough — leaving the bottom third of the wound unpacked allows bleeding to continue beneath the gauze
3. Lifting pressure to check too soon — breaks early clot formation; hold for the full time
4. Using a single folded piece — one folded pad is not enough; use the entire roll, packing systematically
5. Skipping after-pack bandaging — without a securing bandage, the patient or rescuer movement will loosen the pack

Quick Reference

Step	Key Point
When to pack	Junctional wounds, deep cavity wounds, any wound where tourniquet cannot be applied
Starting point	Deepest part of the wound — pack from bottom up
Technique	Sequential folds pushed firmly with finger — not loose stuffing
Pressure duration	3 min (haemostatic gauze), 5 min (arterial), 10 min (plain gauze)
Check bleeding	Do NOT lift to check during the 3–10 minute hold
If bleeding persists	Add more gauze and pressure on top of existing pack
Secure	Pressure bandage over the packed wound
Patient allergy	Celox contains chitosan (shellfish-derived) — note allergy but still use in life-threatening bleed
Remove the pack?	No — leave for surgical team
Next step	Call emergency services if not done; monitor for shock

Training and Preparedness

Wound packing cannot be fully learned from text alone. The hands-on component — packing a simulated wound under supervision — builds the muscle memory needed to act under stress. Stop the Bleed training (2 hours, available globally) includes wound packing alongside tourniquet application and direct pressure.

Consider keeping haemostatic gauze in your workplace first-aid kit, vehicle emergency bag, and home first-aid supplies. It has a multi-year shelf life, takes up minimal space, and requires no prescription in most countries.
