Evaluation des intraoperativen Einsatzes standardisierter Hypnose mit State-Trait-Angst-Inventar.

BACKGROUND: Surgical treatment under local anesthesia is commonly restricted by limited compliance of patients. Hypnosis may represent an alternative to sedation or general anesthesia. As the procedure demonstrated promising prospects during 1-year experience, the observed hypnosis-induced effects are now being evaluated in clinical studies. PATIENTS AND METHOD: The prospective study included 50 patients scheduled for dental surgery. All procedures were performed under standardized surgical conditions. The experimental group (n=25) received supplementary standardized tape hypnosis, whereas the control group received standard treatment (only local anesthesia). Individual and situative anxiety levels were determined by the State-Trait Anxiety Inventory (STAI). RESULTS: After simultaneous increase of preoperative state anxiety, anxiety levels in the hypnosis group showed a significant intraoperative reduction to baseline level, whereas intraoperative anxiety of the control group (n=25) remained unchanged. CONCLUSIONS: Hypnosis reduces intraoperative anxiety of oral and maxillofacial patients significantly. Further clinical studies on the use of hypnosis are considered useful.
