Anaesthesiology is the branch of medicine that is involved in providing pain relief to patients with the help of medications called anaesthetics and in ensuring patients are in a stable condition before, during and after an operation.Anaesthesia is used in a wide variety of disciplines chiefly focussing on pre and post surgical pain management, critical care and emergency, diagnostics and palliative care. Anaesthesiologists are trained in managing pain in patients undergoing a variety of procedures and are responsible for keeping the patient safe and stabilised at all times during and after the surgery. They ensure patients are comfortable following a surgery through the administration of pain relievers.
