Efficacy of Non-Opioid Analgesics on Opioid Consumption for Postoperative Pain Relief After Abdominal Hysterectomy

Abstract Objective: The purpose of this study was to compare the analgesic efficacy and pain intensity of and patient's satisfaction with non-opioid analgesics while evaluating postoperative piritramide consumption for providing pain relief after abdominal hysterectomy. Design: This was a randomized, double-blinded study. Materials and Methods: With the patient under general anesthesia, surgery was performed on 120 women using propofol, remifentanil, and muscle relaxant. Four patient groups (n=30 each) were treated over 24 hours with normal saline (NaCl), parecoxib, metamizol, or paracetamol in addition to piritramide using the patient-controlled analgesia (PCA) pump. Postoperatively, patients were asked every 2 hours for the first 6 hours, and afterwards once every 6 hours, to quantify their pain experience at rest on different pain scales, including patient satisfaction. Cumulative piritramide consumption within 24 hours postoperatively was recorded on the display of the PCA pump. Results: The first req...
