"conversational hypnosis" as the approach is known, may do a better job than pills for relaxing patients before anesthesia and surgery, suggests research being presented at the ANESTHESIOLOGY™ 2015 annual meeting.
In the study of 100 patients undergoing hand surgery, 50 had conversational hypnosis while being given regional anesthesia, and 50 were given 25 mg of oral hydroxyzine 30 minutes to an hour before the induction of anesthesia. Their levels of relaxation were assessed using the ANI as well as the comfort scale, both prior to and after receiving hypnosis or medication and anesthesia.
Patients measured an average ANI of 51 before and 78 after hypnosis, whereas those who had medication averaged 63 before and 70 after. The average comfort scale of those who had received hypnosis was 6.7 before and 9.3 after, while patients who had medication averaged 7.8 before and 8.3 after.
