Hypnosis is increasingly recognised as having a valuable role in surgery. Some of the many benefits of incorporating hypnosis into surgery include the reduction of chemoanaesthesia during surgery and analgesics post-operatively. Research evidence indicates that hypnosis can reduce pre-operative apprehension, decrease anxiety, stress and adverse effects during surgery and diminish post-operative nausea and discomfort. Hypnosis may even be helpful in assisting the patient in the fight against infections post-operatively. Hypnosis can improve haemodynamics during surgery and improve ability to cope with the demands of surgery and chemoanasthesia. This can help towards better outcomes in surgery. Many studies have also reported that using hypnosis in surgical operations can lead to an improvement in healing, quicker recovery and marked improvement in overall experience leading to greater patient satisfaction. It has also been demonstrated that if there are medical reasons and advantages for avoiding chemical anaesthetics in certain cases then hypnosis can sometimes be used as the sole anaesthetic in various surgical procedures.
