What is exsanguination?
loss of blood volume resulting in death
Components of trauma triad of death
1. hypothermia
2. coagulopathy
3. acidosis
Bleeding from open skull fx
loose sterile bandage
External bleeding would be the most difficult to control in a pt with a large lac to the
brachial artery
carotid artery
femoral vein
jugular vein
carotid artery
Much of the bleeding associated with unsplinted fxs continues because
-most fxs are unstable and usually lacerate major blood vessels
-pt anxiety increases the BP which exacerbates bleeding
-bone ends will continue to move and destroy partially formed clots
-swelling associated with such fxs prevents platelet aggregation
-bone ends will continue to move and destroy partially formed clots
