My father is 81. He fell on his face and did not go to hospital until next day. He is on Coumadin and had a hematoma. Had surgery after two weeks in the ICU. He has A Fib, has had serious melanoma surgery , had both shoulders replaces, has fallen and broken his arm 2 times in past year with pins and truss system to support elbow now. Lots of surgeries in the past several years. Has had a few small strokes. What is his chance of coming out of coma after almost 4 weeks after craniotomy and having any quality of life. He is breathing 4-5 hours a day on his own but has trach and peg tube. Mom says he blinks his eyes when talked to.
