    BackgroundAlthough it can be reduced, postoperative pain remains a problem. Acupressure with electric stimulation may be more effective for postoperative pain management than acupressure alone.ObjectivesThis study aimed to evaluate the effects of integrative acupoint stimulation (IAS) on the relief of postoperative pain and on the reduction of morphine-related side effects.DesignA single-blinded, sham-controlled study with three groups.SettingAn orthopedic ward in a 2900-bed teaching medical center.ParticipantsForty-five subjects in each of three groups.MethodsEach subject received a multimedia course on patient-controlled analgesia (PCA) before surgery to learn about the use of narcotic analgesics and the operation of the PCA device. Treatment was as follows: (1) for the IAS group, auricular acupressure combined with transcutaneous electric acupoint stimulation (TEAS) at the true acupoint; (2) for the sham group, acupoint stimulation in the same manner but at a sham acupoint or without embedding seeds and pressure; (3) for the control group, no IAS intervention.ResultsPain scores were significantly lower in the IAS group than the other two groups at 2h and 4h after returning to the ward, and 24h after surgery. The analgesic requirement during the 72h after surgery and the overall incidence of morphine-related side effects were significantly lower in the IAS group.ConclusionThe study demonstrates that combined auricular acupressure and TEAS decreased postoperative pain, the use of equianalgesic morphine, and morphine-related side effects. IAS provides better analgesia when used in conjunction with PCA after lumbar spine surgery and can be regarded as a component of multimodal analgesia.Copyright © 2013 Elsevier Ltd.
