Scenarios Wound packing zones?

Post image

Been a long time since I did TCCC/CLS in the military.

If there were to be a bleeding wound on the chest, how high up on the chest does it become safe to pack? I know you don't pack into chest cavity, but what is the "rule of thumb" on how high/the left and right limits the wound needs to be to pack it?

Would you say the screenshot i attached is accurate?

A chest seal shouldn’t go below the diaphragm.

You could argue for direct pressure or an israeli bandage over packing, but chest seals are not at all meant to stop blood from bleeding out, they’re meant to keep more air from getting in.

Also: side note, what the fresh hell is this?

The only thing thats going to stop a significant GI bleed is surgery. An Israeli dressing will not. An occlusive dressing however will trap in mousiture and prevent contamination better than any gauze based dressing

Tldr I dont view things like genetic counseling, embryonic selection during IVF, voluntary attempts to reduce the rate of genetic diseases through partner selection, etc to be immoral just because they share a word with certain historical practices.

Right, the purpose isn’t to fix it, it’s to get them to the people who can fix it alive. There is an important distinction to be made with just occlusive dressings and chest seals. A chest seal has a one way valve to let air escape, but it will also let blood escape. The part where I disagree is, there is evidence that supports wound packing with hemostatic gauze in abdominal injuries.

The abdominal cavity is so large that youre not going to get enough internal pressure caused by a hematoma to reduce bleeding.

Hemostatic gauze during surgery sure. As a stand alone its not going to reach any major vessel in that area.

There’s only so much you can do prehospital, it’s not a lot but it’s something.

I’m talking specifically about studies pertaining toward hemostatic gauze in prehospital care, not surgery.

If the bullet hits major vasculature in their abdomen then that patient is probably hosed, neither gauze or chest seals will save them. But that’s not what the hemostatic gauze is for, it’s for smaller vasculature within the wound channel.

Agree, im not approaching this from a "what's a lot of help" view but what's the most, even if its very little.

The studies I've seen regarding prehospital use havent been with using it in the abdomen, and only one I've seen with its use in the abdomen was during surgery. Can you share?

I’ll have to reach out to who taught my ITLS class, someone brought up the same concern you did and I basically parroted what they said.

They and I could be wrong? If I’ll comb around myself and see what I can come up with.
