Unless u know how to use sutures and a nasal Trumpet they are useless. Most wounds sustained in the field should not be sutured closed in the field without extensive rinsing with a antiseptic of some type. Even then often times if a wound is grossly contaminated we do not suture them closed. It looks cool in Hollywood a skin suture and magically all bleeding stops. I can tell you that is not how it works at all. If bleeding is an issue in the field lots of direct pressure is best. If it’s a limb bleed and life is at risk from bleeding a tourniquet is an option knowing that I may cause irreversible harm to the limb but may save a life.
I would highly recommend ads advanced wilderness life support class or the book is also fantastic if you have a medical background. Even without bet it would be helpful for lots of people.
