Anesthesiologists

It is the branch of medical science or specialty practice of physicians (anesthesiologists) or other clinicians such as Anesthetists that deal with providing anesthesia and anesthetics. Anesthesia is the blocking of pain. Anesthetics are drugs that block pain and/or put you in an unconscious or sedated state so that medical procedures and surgical procedures can be done.

When determining the meaning of a medical word you read the word starting with the suffix or ending then you read the prefix or beginning and then the root or middle of the word. Logy- is the suffix meaning the study of, an- is the prefix meaning without, and esthes/o- is the root word meaning sensation or feeling. So when you put those together the word means the study of being without feeling or sensation.
