Whats an Induced Coma?
Via Slate:Doctors can try to reduce swelling by putting the patient in a coma. (Among the other available options: opening a hole in the side of the head to let out fluid, cutting out portions of the inflamed brain, or inducing hypothermia.) Inducing a coma is beneficial because a comatose brain uses less energy—and oxygen—than an awake and alert one. A brain that’s been shut down in a coma can survive longer with a limited supply of oxygen. The coma also further reduces blood flow to the brain, which eases pressure in the cranium.
