Anesthesiologists administer anesthetics to make patients insensible to pain during surgery.
They also provide respiratory and cardiovascular life support to injured or ill patients in emergency departments and intensive care units. Anesthesiologists are fully qualified physicians. To become anesthesiologists, students complete college, medical school, and a residency in anesthesiology. The process may take twelve years or more after graduation from high school. There are no Missouri colleges or universities in which you could major in this field.
