Jacob Hall, 6 years old, died of a femoral artery laceration after being shot by a 14-year-old at recess at school. No one knew how to apply a tourniquet. Tourniquets do work on kids.
Just recently, the first case report of a commercially available tourniquet being placed on a child was published. A 7-year-old sustained a femoral artery laceration when a piece of metal flew out of a running lawnmower. Although in shock by the time prehospital providers arrived, he survived after a commercial tourniquet was placed, before transport to the hospital. See more on the blog.
