Celox type hemostatics are specifically contraindicated for abdominal, thoracic and open skull trauma. Verboten. No bueno. Bad news. The 2ndary dangers are too great in those specific bodily neighborhoods. But now we get into the weeds. Hemostatics come in many forms. Natural polymers: collagen, cellulose, chitin..(just hope the patient doesn't have a shell fish allergy) Various synthetic polymers. Metal (usually aluminum or silver) based agents. There may be certain exogenous hemostatics that are ok for ab wounds in the field, but if so, they have been implemented after my time. But Celox is not one of them Israeli (gasp!) bandages should be in every serious stop-the-bleed kit. They are essentially and pre-fab pressure dressing and are even vac packed to save space. Gauze, chest seals abdominal bandages and the mighty T (tourniquets), too. And, of course, the even mightier T to tie it all together: Training. All the cool guy gear in the world is worth fuck all unless effectively deployed and applied.
