Brain surgeryIn 1923, the first operation to remove a brain tumour under local anesthetic (cocaine on the patient's scalp) was performed at Beth Israel Hospital in New York City by a team of surgeons led by Dr. Karl Winfield Ney (d. 31 May 1949). The 4"x2"x¾" tumour was benign, but still life-threatening. The patient's condition had been deemed too risky for a general anaesthetic. So Henry A. Brown was fully conscious throughout the operation and able to answer the doctors' questions. Ney was a one-time chief of surgery for the French Red Cross. He served in the U.S. Army Medical Corps from 1917 to 1921. «* |
