Wound Packing & Junctional Bleed
Objective: Pack deep and junctional bleeding to the source, hold real pressure, and keep packing out of the chest — that hole gets a seal, not a roll of gauze.
Why This Is Hard
Limb tourniquets do not reach the groin, axilla, or neck. Those junctional bleeds hide under clothing and kill as fast as a femoral. CoTCCC: hemostatic dressing (Combat Gauze or equivalent) packed into the wound, at least 3 minutes of direct pressure (optional for XStat), then a pressure bandage. If a junctional tourniquet is available and the site fits, apply it — do not wait to finish a pretty pack first if the device is ready.
- Expose clothing. The hole is often under a belt or in the groin crease — not where the first glance lands.
- A chest hole gets a seal, not packing. Packing into the thorax is the wrong hole.
- Hold pressure for the full teaching interval. Peeking at 20 seconds is how junctional bleeds restart in the back of the truck.
- Junctional — not a CAT-on-the-torso problem
- Pack to the bleeding source / bone, not a surface puff
- Hold pressure — do not peek at 20 seconds
- Chest hole → seal, not pack (see open chest wounds)
How Packing Works (Education)
- Expose. Scoop out massive clots only enough to see the hole — you are not doing surgery.
- Feed gauze into the track with a finger or instrument per training, down to the source. Keep packing until the cavity is full. One roll is often not enough.
- Hold firm pressure for about 3 minutes with hemostatic gauze (CoTCCC). Do not lift to “check.”
- Pressure bandage over the pack. Reassess. If it soaks through, reinforce or repack per training — do not just stack dry 4×4s on top and hope.
Hemostatic vs Plain
- Hemostatic gauze is preferred when you have it. Plain gauze packed tightly with pressure still beats a fluttering trauma dressing.
- XStat-type expanding sponges are for deep narrow tracts and are not pulled in the field. Know what you carry.
- Do not pack the thoracic cavity. Open chest wounds get a vented seal and a tension watch.
Neck
Packing a neck wound is a trained, careful skill — airway and expanding hematoma live here. Direct pressure that does not occlude both carotids is the first move. Follow protocol; this is not a “stuff the whole roll in” site for the untrained.
Field Pitfalls
- Surface dressing on a 6-inch tract.
- Packing a sucking chest wound like a junctional bleed.
- Peeking every 15 seconds so the clot never forms.
Practice
60-second drill
On a packed-wound trainer (or a rolled towel with a hole), pack until you cannot add gauze, then count 3 minutes of pressure out loud. Partner names: groin vs chest vs mid-thigh — pack, seal, or TQ.

Named guidelines for further study. They are not clinical orders and do not replace your protocol or medical direction.
- NASEMSO National Model EMS Clinical Guidelines (2022) — U.S. EMS model language; protocol still wins
- TCCC / CoTCCC — Combat Gauze first-line hemostatic; 3 minutes pressure; junctional TQ when the site allows
- TECC
- Pack junctional and deep wounds. Seal the chest. Protocol owns devices.
