"Overall, 9.6 percent of the study patients had amputations, and more than one-third of those patients had received a tourniquet. However, amputation patients who received a tourniquet had significantly lower mortality rates than those who did not — 2.9 percent vs. 7.9 percent."
I remember being trained to only do them in life or death situations due to the risk/damage to the effected limb. Which kind of never made sense to me. If it's bad enough to consider a TQ it's probably bad enough to just need one. Looks like you are trading a limb for a life though based on those numbers. I gotta think most folks would take that trade in a bad situation. But I also think folks need to understand that going in. There is a real chance the TQ both saves the life and helps ensure an amputation. At least make that thought a part of the mental math. In the end it's a similar math to moving an injured patient. If you are sure they are going to die by not moving, then move them the best you can and hope for the best.
