Anaesthesia

  Anaesthesia means "sensational loss" Anaesthetic medicines are called anaesthetics. Anaesthetics are used to relieve pain in other parts of the body or to promote relaxation during procedures and surgical operations. It reduces suffering and distress, which allows for a wide variety of surgical procedures. Procedural sedation is used for operations that do not involve general anesthesia and make patients endure treatments that may otherwise be unpleasant or painful. Conscious sedation is characterized as a condition caused by medication that decreases the patient 's degree of consciousness during which the patient may respond to verbal orders or light stimulation through touch intentionally. Clinical anaesthesia is based on knowledge of physiology (how the body works) and pharmacology (how the body works with medication). A detailed knowledge of how the body reacts to anesthesia and surgery is needed, and how the patient's wellbeing influences and changes these physiological responses.
