title: Effects of Positive Suggestions on the Need for Red Blood Cell Transfusion in Orthopedic Surgery.
abstract: This study examined whether positive suggestions applied without a hypnotic induction in the perioperative period reduces the need for red blood cell transfusions in patients who underwent total hip or knee arthroplasties with spinal anesthesia. No hypnotic assessment was performed. Ninety-five patients were randomly assigned to the suggestion group (n = 45) and to the control group (n = 50). Patients in the suggestion group received verbal suggestions before and audiotaped suggestions during the surgery for reducing blood loss, anxiety, postoperative pain, and fast recovery. Our study showed that using positive suggestions in the perioperative period significantly decreases the necessity for transfusion.
