Anesthesiology is a branch of medicine that focuses on pain relief during and after surgery. This treatment is called anesthesia. Practitioners of anesthesiology are called anesthesiologists or, in some countries, anaesthetists.
Anesthesiologists often also undertake non-surgical pain relief and critical care management.
