There are numerous specialities within the field of Anaesthetics including that of Cardiac Anaesthesia, General Anaesthesia, Paediatric Anaesthesia, and ITU. As one of the essential medical fields, Anaesthetics have grown in importance not only because the anaesthetist provides general anaesthesia before and during surgeries, but also because of advances in technology and medicine. Epidurals, nerve blocking, and other techniques are used to bring about patient comfort during painful operations.
