Auricular Acupuncture in Postoperative Pain

The effect of acupuncture for postoperative pain control remains controversial. We therefore studied the effects of electrical auricular acupuncture (AA) on postoperative opioid consumption in a randomized, patient-blinded clinical trial. 40 female patients undergoing laparoscopy were included. Anaesthetized patients were randomly assigned to receive AA (shen men, thalamus and one segmental organ-specific point) or electrodes and electrical stimulation for 72 hours. Postoperatively patients received 1 g paracetamol every 6 hours and additional piritramide on demand. A blinded observer obtained the doses of piritramide and the visual analogue pain scores (VAS) at 0, 2, 24, 48, and 72 hours. It was the aim of our study to find out, whether auricular acupuncture reduces postoperative pain.
