In previous posts on first aid for the homesteader, prepper, etc., we have covered not only some basic items to have in your medical supplies, but how to use them. This post goes a little more in depth with a more advanced product to have and how to use it.

A Little Bit of History
Saving myself hours of medical research and you a lot of boring reading, here's the jist of where this product came from...
A hemostatic agent is one that speeds the clotting of blood. You can find Merriam-Webster's definition here.
Different materials have been used over the years, to include the shells of marine arthropods as well as potato starches. More reading on that subject and the use of these agents in Emergency Medical Services here. The problem with the early forms of these agents has been either the overall success with stopping blood, or the side affect of the product creating heat and damaging skin (initially used as a powder which was poured onto the bleeding wound). So, fast-forward through a few years of development along with testing by both military and civilian medical professionals and we have a rolled (or folded) gauze that is impregnated with a hemostatic agent.
Quik Clot Rolled Gauze/Combat Gauze and Celox
Combat Gauze is the third generation of Quik Clot. This and Celox are both rolled gauze impregnated with a hemostatic agent. Quik Clot uses Kaolin, a type of clay containing Aluminum Silicate. Celox uses a product made from shells from marine arthropods, as mentioned above.
Basically, these companies can argue all day long about which one works better, but either one is better than none at all. If you have an allergy to shellfish, don't leave just yet. The material Celox uses is purified and the companies claim it will not cause an allergic reaction.
How To Use It
The instructions are pretty simple. Quik Clot has a simple step-by-step guide written on the package. It goes like this...
1. Open the package, remove the gauze, keep the empty package.
2. Pack the gauze into the wound and use it to apply pressure directly over bleeding source. (More than one gauze may be required).
3. Continue to apply pressure for 3 minutes or until bleeding stops.
4. Wrap and tie bandage to maintain pressure. Seek medical care immediately. Show PRODUCT REMOVAL directions on package to medical personnel.
PRODUCT REMOVAL: 1. Gently remove gauze from wound. 2. Thoroughly irrigate wound.
That's it. 4 steps. The last one is for the guy with the lab coat, or at least someone in scrubs. Obviously in a long term remote location you may have to play that role as well, but lets hope not.
So, to wrap this up, consider having hemostatic gauze in your medical supplies at home and in your mobile medical kit. You never know when you might need it!
I hope this information helps you with developing skills as a homesteader, prepper, missionary, hiker or whatever. Let me know!
