4. Anaesthesia
Anesthesiology may be the least understood specialty on this list. Their main duty lies in providing a safe anesthesia to patients during surgical operations, but that is far from their only role.
They care about patients before and after operations, but they increasingly take on managerial roles as well.
After the required four years of medical school, four years of residency will be necessary for you before pretending to the title of the anesthesiologist.
