The effects of hypnosis in connection with surgery have been described in many clinical publications, but few controlled studies have been published. The aim of the present study was to evaluate the effects of preoperative hypnotic techniques used by patients planned for surgical removal of third mandibular molars. The patients were randomly assigned to an experimental (hypnotic techniques) or a control (no hypnotic techniques) group. During the week before the surgery, the experimental group listened to an audiotape containing a hypnotic relaxation induction. Posthypnotic suggestions of healing and recovery were given on the tape together with advice regarding ways to achieve control over stress and pain. The control group received no hypnotic intervention. Only one surgeon who was not aware of patient group assignments performed all the operations. Thirty-six patients in the control group were compared to 33 patients in the experimental group. Anxiety before the operation increased significantly in the control group but remained at baseline level in the experimental group. Postoperative consumption of analgesics was significantly reduced in the experimental group compared to the control group.
催眠与手术相关的效果已在许多临床出版物中有所描述，但发表的对照研究很少。本研究的目的是评估计划接受下颌第三磨牙拔除手术的患者术前使用催眠技术的效果。患者被随机分为实验组（催眠技术组）或对照组（无催眠技术组）。在手术前一周，实验组听一盘包含催眠放松诱导的录音带。录音带上给出了术后愈合和恢复的暗示以及关于控制压力和疼痛方法的建议。对照组未接受催眠干预。只有一位不知道患者分组情况的外科医生进行了所有手术。将对照组的36名患者与实验组的33名患者进行比较。对照组术前焦虑显著增加，而实验组则保持在基线水平。与对照组相比，实验组术后镇痛药的消耗量显著减少。
