Efficacy of Hypnoanalgesia by a Radiologist Technologist in Children With Cutaneous Angioma Treated With Sclerosis in Interventional Radiology

"The running of a hypnosis session is protocolized and is based on three times:~* The hypnotic induction time that allows to move from the state of consciousness to a modified state of consciousness: it will be adapted according to the patient as specified by the procedure of Ericksonian hypnosis. It varies from a few seconds to 10 minutes. Induction time depends on the patient's level of stress, apprehension, subsequent experiences of hospitalization, history, and level of hypnotizability.~* The dissociation time. It is the state of modified consciousness obtained at the end of the induction which is prolonged,~* The time of return. It is time that allows the patient to regain his classic state of consciousness."

"The pain management will be done exclusively by a mask delivering the equimolecular mixture of oxygen and nitrous oxide (MEOPA) throughout the procedure.~For optimal use, the beginning of its administration by the radiological technologist is performed 3 minutes before the sclerosant injection (at the end of the locating ultrasound). The end of administration will correspond to the end of the injections of the sclerosing product. These sclerosing products are not considered experimental or ancillary products in this study."
