Pre- and perioperative suggestion in maxillofacial surgery: Effects on blood loss and recovery

Abstract

The basic assumption underlying the present study was that emotional factors may influence not only recovery but also blood loss and blood pressure in maxillofacial surgery patients, where the surgery was performed under general anesthesia. Eighteen patients were administered a hypnosis tape containing preoperative therapeutic suggestions, 18 patients were administered hypnosis tapes containing pre- and perioperative suggestions, and 24 patients were administered a hypnosis tape containing perioperative suggestions only. The patients who received taped suggestions were compared to a group of matched control patients. The patients who received preoperative suggestions exhibited a 30% reduction in blood loss. A 26% reduction in blood loss was shown in the group of patients receiving pre- and perioperative suggestions, and the group of patients receiving perioperative suggestions only showed a 9% reduction in blood loss. Lower blood pressure was found in the groups that received pre- and perioperative and perioperative suggestions only. Rehabilitation was facilitated in the group of patients receiving perioperative suggestions only.
