During hypnosurgery, a hypnotist helps the patient control their subconscious reflexes so that they do not feel pain in the traditional sense. Patients are aware of sensation as the operation progresses and often describe a tingling or tickling sensation when pain would normally be expected.
The main benefit of hypnosurgery is that there are fewer side effects, and generally a patient can leave hospital sooner than if normal anaesthetics are used. A reduction in blood loss and post-operative nausea have also been recorded. It should be noted, however, that further studies are being performed and that hypnosurgery is not suitable for all patients.
