Integrative acupoint stimulation to alleviate postoperative pain and morphine-related side effects: A sham-controlled study

The 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.
