So for more so those who find this while searching, I came across this looking for wound packing slides in hopes I wouldn't have to make them -__- But anyways reading this thread I think most people are missing the fact that this is being taught for emergency intervention prehospital. In the hospital they may wound pack or utilize other means. When I deploy I always have several tourniquets on me to include a junctional, if I have uncontrolled bleeding, I would use one of those immediately, even stateside in ambulance services hands down. However, if I don't have a junctional tourniquet or I have a GSW to a weird place, then I would wound pack the hell out of it. the notion of holding pressure and elevating makes sense on paper but in an emergency or during care under fire (police too) your not gonna sit there with your hand on a wound waiting when you have other things that take precedence which is when wound packing becomes a great alternative. Idk about others but Civilian Paramedicine does talk about wound packing, at least the school I went to. Military PHTLS and TCCC go way more in-depth with it as well to include hemostatic agents. To properly do it, its best to use something like compressed gauze or kerlix so you don't have a bunch of pieces everywhere, but you use what you have. Also, just packing a wound wont do anything but act like a sponge, the idea of it is if you know your anatomy and can find the source of the bleeding, your initial packing will be on the vessel to help potentiate clotting and then pack the hell out of the wound to give it added pressure. I cant speak for hospital protocols, but if your teaching policemen or firefighters or medics this is what I've done and seen in my experience both stateside and deployed.
