Wound packing is how you control major bleeding where a limb tourniquet can't go: the groin, the armpit, the base of the neck and similar junctional areas. You fill the wound cavity with gauze, pack it down to the bleeding source, and hold firm pressure until the bleeding stops or someone with more capability takes over.
Tourniquets get most of the attention in law enforcement medical training, and they should be on every officer. But a round or a blade that lands high on the thigh or in the armpit creates a bleeding problem a tourniquet can't solve. Packing, pressure, hemostatic dressings and, where issued, junctional tourniquet devices are the tools for that job.
This guide explains what the guidelines say about each one. It quotes the June 2015 C-TECC guidelines. We could not open the 2024 C-TECC First Responder guidelines when this was written, so confirm current wording with C-TECC and your medical director.
What is junctional hemorrhage?
Junctional hemorrhage is bleeding where the limbs or neck join the torso. A StatPearls review on EMS junctional hemorrhage control (updated June 2026) defines it as "Hemorrhage occurring at the junction between the torso and the neck or between 1 or more extremities." It lists the sites as the groin, axilla (armpit), perineum, shoulder girdle and base of the neck.
These areas carry major blood vessels, and bleeding there can be just as fast as a limb wound. The Joint Trauma System's Damage Control Resuscitation guideline states that "Hemorrhage is the leading cause of preventable death on the battlefield." The same guideline says effective extremity tourniquets "may be responsible for saving more wounded service members in Iraq and Afghanistan than any other single medical intervention." Junctional wounds are the bleeding a tourniquet can't reach.
Why don't tourniquets work on junctional wounds?
A limb tourniquet works by wrapping all the way around an arm or leg and squeezing the artery against bone. At the groin, the armpit or the neck, there's no limb left to wrap. The same StatPearls review notes that "Standard extremity tourniquets are generally ineffective due to the proximal location of injury."
This is also why the TCCC guidelines limit limb tourniquets to hemorrhage "that is anatomically amenable to tourniquet use." If the wound is too high for a tourniquet to sit above it, you need a different tool. See our tourniquet application guide for where tourniquets do work.
High thigh wounds sit right on that line. In April 2026, Columbus officers applied a tourniquet to a partner whose femoral artery was reportedly hit, then drove him to the hospital. A wound a few inches higher might not have left room for one. Officers need reps at both skills, and the judgment to tell which one the wound needs.
What is wound packing?
Wound packing means pushing gauze into the wound until the cavity is filled and the gauze presses on the source of bleeding. Then you hold pressure on top of it. Surface pressure alone can miss the bleeding vessel. Packing brings the pressure to it.
The American College of Surgeons' Stop the Bleed booklet tells bystanders to "Pack (stuff) the wound with bleeding control gauze (also called hemostatic gauze), plain gauze, or clean cloth."
StatPearls describes the technique this way: "One hand should advance the gauze into the wound, while the other maintains the packing material's position to sustain continuous pressure." It also stresses constant pressure, without letting up to check whether the bleeding has stopped.
Hemostatic dressing vs plain gauze: which should you use?
Hemostatic gauze is gauze treated with an agent that helps blood clot. StatPearls describes hemostatic dressings as "bioengineered dressing materials impregnated with hemostatic agents."
The guidelines differ in how much they prefer it:
- C-TECC (2015): "For compressible hemorrhage not amenable to tourniquet use, or as an adjunct to tourniquet removal (if evacuation time is anticipated to be longer than two hours), apply a hemostatic agent in accordance with the directions for its use along with an appropriate pressure bandage."
- TCCC (1 May 2026): names a CoTCCC hemostatic dressing of choice and lists alternative hemostatic adjuncts for compressible bleeding.
- ACS Stop the Bleed: hemostatic gauze, plain gauze or clean cloth are all acceptable for packing.
The practical takeaway: pack with hemostatic gauze if you have it, because that's what the tactical guidelines call for. If all you have is plain gauze or a clean cloth, pack the wound anyway. Good packing and hard, steady pressure matter no matter what gauze you use. Which hemostatic product your agency issues is a medical-direction decision.
How long do you hold pressure on a packed wound?
It depends on which guideline you follow, and the 2015 C-TECC document doesn't give a number.
- TCCC (military): "Hemostatic dressings should be applied with at least 3 minutes of direct pressure."
- ACS Stop the Bleed: "Continue pressure until relieved by medical responders."
- C-TECC (2015): calls for a hemostatic agent with a pressure bandage but states no pressure time.
The 3-minute figure is a floor for hemostatic dressings in TCCC, not a timer that says you can stop. If bleeding continues, keep pressure on and follow your training. Don't lift the dressing to check whether the bleeding has stopped. That breaks the clot you're trying to build.
What is a pressure dressing?
A pressure dressing holds pressure on the wound so your hands are free. StatPearls describes it as "a bulky sterile dressing secured in place with a tight circumferential band." This can remove the need for continuous manual pressure from the provider.
C-TECC pairs hemostatic agents with "an appropriate pressure bandage." In a tactical setting, freeing your hands is a big deal. You may have to move the casualty, treat another wound, talk on the radio or get back to security. Once the bleeding is controlled, a well-applied pressure dressing lets you do that without losing control.
What are junctional tourniquets?
Junctional tourniquet devices are built to compress the artery at a junctional site, such as the groin, where a limb tourniquet can't work. StatPearls notes several FDA-cleared designs that "function through proximal arterial compression."
Both guidelines say to use one right away if the wound calls for it and the device is available:
- C-TECC (2015): "If the bleeding site is not amenable to tourniquet application, cannot be controlled by direct pressure and hemostatics/dressings and a junctional tourniquet device is available, immediately apply a junctional tourniquet device in accordance with directions for its use."
- TCCC (2026): "If the bleeding site is amenable to use of a junctional tourniquet, immediately apply a junctional tourniquet. Do not delay in the application of the junctional tourniquet once it is ready for use."
Note the C-TECC order: pressure and hemostatics first, the junctional device if those fail and one is on hand. Most patrol officers won't carry a junctional device. They're more often found with tactical medics and team medical kits. Your training and issue decide whether it's in your lane.
Where does this fit in TECC?
In the Direct Threat Care phase, the 2015 C-TECC guidelines say to "Consider instructing casualty to apply direct pressure to the wound if no tourniquet available or application is not tactically feasible." Deliberate packing, hemostatic dressings and junctional devices belong to Indirect Threat Care. That's the "M" (massive hemorrhage) in the MARCHE assessment, once you've reached a safer position and can expose the wound.
The JTS Vascular Injury guideline lists "Pressure dressings, tourniquet placement, wound packing, etc." as initial prehospital care. It treats them as a set, not as rivals.
What you are authorized to do depends on your training level, your agency's protocols and your medical direction. Packing a real wound under stress is a hands-on skill. Reading about it is not practice.
Frequently Asked Questions
What areas count as junctional hemorrhage?
Junctional areas are where the limbs or neck meet the torso. A StatPearls review lists the groin, axilla (armpit), perineum, shoulder girdle and base of the neck. Standard limb tourniquets generally can't control bleeding from these sites.
Can you pack a wound with regular gauze?
Yes. The American College of Surgeons' Stop the Bleed booklet says to pack with hemostatic gauze, plain gauze or clean cloth. Tactical guidelines prefer hemostatic dressings, but a well-packed wound with plain gauze and firm pressure beats waiting for the "right" gauze.
How long do you hold pressure after packing a wound?
The military TCCC guidelines call for "at least 3 minutes of direct pressure" with hemostatic dressings. Stop the Bleed says to continue pressure until medical responders take over. The 2015 C-TECC guidelines don't state a time. Keep pressure on as long as it's needed.
Why can't you use a tourniquet on the groin or armpit?
A limb tourniquet has to go all the way around an arm or leg to squeeze the artery against bone. At the groin, armpit or neck there's no limb to wrap. The bleeding needs packing, pressure or a junctional device instead.
What is a junctional tourniquet?
It's a device that compresses the artery at a junctional site, like the groin, where a limb tourniquet won't fit. C-TECC's 2015 guidelines say to apply one immediately if pressure and hemostatics fail and a device is available. Whether you carry one depends on your role and agency.
