The radio tones drop for a “shooting in progress” and your adrenaline instantly spikes. It’s the call every EMT dreads but must be ready for. When seconds count, hesitation costs lives, and knowing your gunshot wound treatment EMT protocol is the difference between a save and a loss. This isn’t just about following a checklist; it’s about mastering the MARCH algorithm to prioritize the kill threats first. In this guide, we’ll walk through the exact steps to manage penetrating trauma, from scene safety to the trauma bay doors.
Scene Safety & BSI: The Non-Negotiables
Imagine pulling up to a chaotic scene with people running and shouting. It’s tempting to rush in and grab the patient, but you are no good to anyone if you become a casualty yourself.
Your first priority is always ensuring the scene is safe. Wait for law enforcement to clear the “hot zone” before you enter. You cannot treat a patient if you are taking fire.
Once cleared, don your Personal Protective Equipment (PPE) immediately. Gunshot wounds involve blood, bone fragments, and often gunpowder residue.
Pro Tip: Double-glove for penetrating trauma calls. It’s not uncommon for gloves to snag on sharp bone fragments or shattered glass during your assessment.
The MARCH Algorithm: Changing the Mindset
For years, we were taught the ABCs (Airway, Breathing, Circulation). In penetrating trauma, that order gets flipped. A patient can bleed to death from a severed femoral artery in under two minutes.
This is why the military introduced the MARCH algorithm, which is now the standard of care for civilian penetrating trauma protocol.
Here is how MARCH applies to your GSW patient:
- M – Massive Hemorrhage
- A – Airway
- R – Respiration
- C – Circulation (Hypovolemic shock)
- H – Hypothermia / Head injury
See that “M” first? That is your new golden rule.
Managing Massive Hemorrhage
You approach your patient and see bright red blood spurting across the pavement. This is an immediate life threat.
You have two main tools for hemorrhage control EMT: Tourniquets and Wound Packing.
Tourniquet Application
For extremity wounds (arms and legs), a tourniquet is your best friend.
Place it “high and tight” on the limb—proximal to the wound, and as high up the arm or leg as necessary (even over clothing if you must). Tighten the windlass until the bleeding stops and the pulse distal to the injury is gone.
Clinical Pearl: Once a tourniquet is applied, do not remove it in the field. That decision belongs to the trauma surgeons. Note the time of application on the patient’s forehead.
Wound Packing Junctional Wounds
What if the bullet hit the groin, armpit, or neck? You can’t put a tourniquet there.
You must pack the wound. This requires direct, deep pressure.
- Grab your hemostatic gauze (or plain kerlix if hemostatic isn’t available).
- Stuff the gauze directly into the bullet track.
- Pack it tight until you literally meet resistance from bone.
- Hold manual pressure for three full minutes.
Think of it like trying to put out a fire by smothering it. You must fill the cavity to create pressure against the bleeding vessel.
Common Mistake: Placing a dressing loosely over a junctional wound. This won’t stop the bleeding. You have to get your fingers inside the wound.
Tourniquet vs. Wound Packing
| Feature | Tourniquet | Wound Packing |
|---|---|---|
| Best For | Extremities (Arms/Legs) | Junctional areas (Groin, Neck, Axilla) |
| Application | “High and Tight” proximal to wound | Deep, direct pressure inside the tract |
| Time to Apply | Seconds | 3+ minutes of holding pressure |
| Pain Level | High | High |
| Winner/Best For | Rapid limb hemorrhage | Areas you cannot wrap |
Thoracic Trauma Management
You’ve stopped the bleeding. Now you move to Airway and Respiration.
In chest wound management, you are looking for two specific killers: Open Pneumothorax and Tension Pneumothorax.
Open Pneumothorax (Sucking Chest Wound)
Look for a defect in the chest wall. You might actually hear the “suck” of air moving in and out.
This disrupts the pressure in the chest cavity, causing the lung to collapse.
Intervention: Apply a vented chest seal.
Cover the wound completely with the adhesive seal. If you only have a non-vented seal, you must tape down three sides to create a one-way valve effect. However, a commercial vented seal is the gold standard.
Tension Pneumothorax
If air gets trapped in the chest and can’t escape, the pressure builds up and crushes the heart and good lung.
Watch for these signs:
- Respiratory distress
- Tracheal deviation (late sign)
- Absent lung sounds on the injured side
- Jugular Venous Distension (JVD)
If your patient has a chest seal and starts deteriorating, remove it immediately. The vent might be clogged with blood, turning an open pneumothorax into a tension pneumothorax.
Rapid Transport & Packaging
Let’s be honest: You cannot fix a GSW in the back of an ambulance. Your job is to keep the tank full until you get to the surgeon.
“Load and Go” is the standard for penetrating trauma.
As you transport, consider the “H” in MARCH: Hypothermia. Trauma patients bleed out their ability to clot their blood. If they get cold, they die. Cover them with blankets immediately, even if it’s a hot summer day.
Pro Tip: Strip the patient down fully during your assessment, but once they are packaged, cover them up. Preserving body heat is a critical intervention that is often overlooked.
Common Pitfalls to Avoid
We’ve all made mistakes in the heat of the moment. Here are a few to watch out for on your next penetrating trauma call.
- Peeking the Dressing: Don’t lift the dressing to see if bleeding stopped. You will rip off the clot. If blood soaks through, apply another dressing on top and press harder.
- Ignoring Exit Wounds: A bullet creates a tunnel. Always check for an exit wound; it might be larger and more dangerous than the entrance.
- Focusing on the “Hole”: Treat the patient, not the hole. A femoral bleed is more deadly than a messy shoulder wound. Prioritize MARCH, not the most gruesome looking injury.
Conclusion
Mastering gunshot wound treatment EMT protocols comes down to prioritization. Stop the massive bleeding first, secure the chest, and transport rapidly. The MARCH algorithm is your roadmap through the chaos. Trust your training, pack the wound tight, and get them moving. You have the skills to intervene when it matters most.
