On January 8, 2016, I performed my fourth operation under hypnosis. I put the patient into somnambulism, the dentist treated deep caries. The operation was filmed from start to finish. The phenomenon of hypnoanesthesia, of course, exists, it is a medical fact. But it is far from easy to achieve complete pain relief in hypnosis. So, for an operation under hypnosis you need: A deep stage of hypnosis. Fairy tales and metaphors cannot take away the pain, but you can ease it a little. To relieve pain for a long time, fears, if any, should be removed, and somnambulism is definitely needed. Achieve complete dissociation (“the body is asleep, the mind is awake”), which is observed in the deep stages of hypnosis. Be able to maintain the “body-mind” split, for example, through mental travel to pleasant places. Or at the level of preset (tell about Esdaile’s condition) or direct suggestions to constantly induce numbness, coolness... in the operated area of ​​the body. There is a fourth rule, which usually relieves up to half of the pain symptoms. To avoid any freebies, I talk about this in hypnotherapy courses - www.classicalhypnosis.ru/obuchenie-gipnozu. At least there will be insurance that ignoramuses will not experiment with hypnoanesthesia. PHYSIOLOGICAL MECHANISMS OF HYPNOTIC PAIN CONTROL Ernest Hilgard and his colleagues tested the hypothesis that hypnotic analgesia may occur in the medial centers of the brain through the release of endorphins or substances of similar properties. Subjects who were inducing pain relief were given the endorphin blocker naloxone. Since the drug did not have a significant effect on the degree of analgesia, hypnotic analgesia is most likely due to a different mechanism. Hilgard's results were supported by repeated experiments by David Spiegel and Albert Leonard, in which naloxone also did not reduce the relief of chronic pain under hypnosis. Results such as those obtained by Hilgard and Spiegel suggest that the physiological mechanisms of hypnotically induced analgesia are quite complex. Some researchers even doubt that it is possible to identify them all, given the enormous flexibility and structural redundancy of the human body.○ The most comprehensive overview of the phenomenon of hypnoanesthesia: the use of hypnosis instead of anesthesia, surgical operations under hypnosis.
