Hypnosurgery is the term given to an operation where the patient is sedated using hypnotherapy rather than traditional anaesthetics. It is still in its experimental stages, and not often used. During hypnosurgery, the 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. Hypnosis is used in surgery for pain management, to control spasms in the alimentary canal, during rehabilitation and as anaesthesia during operation.
What is more frequently used is hypnosedation, a combination regimen of hypnosis, local injection of analgesics and mild sedation. The patients -mostly aged or other persons that run an increased risk under general anesthesia - are mildly sedated and brought in a state of increased alertness by having them listen to a story in the operation theatre. Anesthesiologists at the University of Liège in Belgium have performed over 4800 surgical interventions, mainly in ENT and thyroid treatments, over the past 10 years.
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.
Hypnosis may also be helpful post-surgery in helping to facilitate faster healing in patients, with one study reporting faster tissue healing in patients who use hypnosis during surgical recovery. Several other studies have shown a psychological link with healing and recovery. In a study of patients up to seven weeks after undergoing a surgical procedure, researchers found greater healing and improvement in patients who had used hypnosis over those who only received supportive attention or standard "standard postoperative care."
