Since 1992, we have used hypnosis routinely in more than 1400 patients undergoing surgery. We found that hypnosis used in patients as an adjunct to conscious sedation and local anesthesia was associated with improved intraoperative patient comfort, and with reduced anxiety, pain, intraoperative requirements for anxiolytic and analgesic drugs, optimal surgical conditions and a faster recovery of the patient. We reported our clinical experience and our fundamental research.
