Many people who think of anesthesiologists think of the person who provides an anesthetic before an operation. While this is true, they also provide much more than this and are responsible for many more treatments. An anesthesiologist is a medical doctor who works in the medical field and provides pain management care, such as anesthetics and epidurals, to patients before a surgery or to treat other pain problems. They work in a variety of medical settings with their patients. Anaesthesiologists provide more than just anesthetics to patients before surgery; they also watch over the patient during surgery, prepare people for surgery, and work with many patients who need pain management.
