When discussing severe bleeding and first aid, the tourniquet often steals the spotlight. Whether its a CAT Gen 7 Tourniquet, DNIPRO Tourniquet, SOF-T Tourniquet or others... They're an incredible, life-saving device that every trauma kit should have. But there is a dangerous misconception that a tourniquet is a universal fix for every major bleed.
The reality? Not every severe injury can be treated with a tourniquet. Depending on where the trauma occurs, relying solely on one could be a fatal mistake. That is exactly why advanced, trauma kits—like the DEPLOY Trauma Kit—always include a packing gauze.
Here is why wound packing is a non-negotiable skill, and why a packing gauze isn't just an "optional extra."
The "High-Up" Problem: When Vessels Retract
Imagine a severe cut high up on a limb. If the injury is within 3 to 4 inches from the top of the arm or leg, applying a tourniquet effectively becomes incredibly difficult, if not impossible.
When a major blood vessel is severed, it can actually retract backward into the body. If the cut is too high, the vessel may pull back beyond the point where a tourniquet can apply pressure to stop the flow. In these scenarios, external restriction of the limb simply won't work. You have to go into the wound and find the source of bleeding.
The Danger Zones: Junctional Injuries
Beyond high limb injuries, there are specific areas of the body where a tourniquet is anatomically useless. These are known as junctional areas:
-
The Neck
-
The Armpits
-
The Pelvis and Groin
For professionals working in high-risk environments—particularly tree climbers using the "cut and push" method (something we are very against) — the risk of a chainsaw kicking back towards the neck or armpit, or a branch or stub causing a major laceration to the armpit or neck is a very real threat. If a catastrophic bleed happens in these areas, you cannot use a tourniquet. You have to pack the junction.
The Solution: Heamostatic and Z-Fold Packing Gauze
Wound packing involves physically packing sterile gauze deep into the wound cavity to apply direct, internal pressure to the severed artery or vein.
Because of the critical nature of these injuries, the DEPLOY Trauma Kit includes specialised packing gauze designed to handle severe hemorrhaging. Depending on your geographical region, these kits are equipped with top-tier options such as:
-
Celox Rapid (Deploy distributed via Mediarb - UK Distributor)
-
QuikClot Combat Gauze (Deploy distributed via Maple Leaf Ropes and Arbsession, Inc. - Canada and USA Distributors)
-
Deploy Z-Fold Packing Gauze (via Reecoil - rest of world distribution)
The Celox Rapid and QuikClot gauzes are haemostatic dressings, meaning they are impregnated with agents that actively promote rapid blood clotting. Helping to speed up the clotting process, above what wound packing with a non haemostatic gauze will do.
Gear is Good, But Training is Essential
Having the right medical devices in your trauma kit is only the first step. You need fast access to them, and more importantly, you need to know how to use them under extreme stress.
If you are working in an environment where major trauma is a risk, don't just carry the kit—train with it. Know the difference between when to apply a tourniquet and when you need to immediately start packing a wound.
Stay safe, get trained, and make sure your kit is built for the reality of the job.
