GENERAL ANAESTHESIA : General anaesthesia is a medicine that is administered intravenously (IV) or through a tube or mask. It is performed by an anesthesiologist. Under general anaesthesia patients are unable to feel pain (analgesic) and will be unconscious. It is commonly used for major operations during surgery. A person may also experience amnesia temporarily following the anesthetic.
SEDATION : Sedation is a medical technique which is used to calm a person before a procedure. It involves giving sedative drugs through IV line. These drugs ease discomfort, pain and anxiety. It depresses a patient’s awareness to the environment and reduction of his or her responsiveness to external stimulation.
REGIONAL ANAESTHESIA: Regional Anaesthesia consists of infiltrating a peripheral nerve with an anesthetic agent and blocking transmission to avoid or relive pain. It blocks sensations of pain from a large area of a body that requires surgery.
LOCAL ANAESTHESIA : Local Anaesthesia prevents pain during medical procedures by numbing a specific part of the body. Its effects are short-lived.
