A study was conducted on twenty-four patients who underwent surgery for retinal detachment as to the clinical effect of acupuncture from the viewpoints of anesthetic dose, intra-operative changes in blood pressure and heart rate, postoperative analgesic state, nausea and vomiting. The patients were divided into two groups: group A, eleven patients receiving neuroleptanesthesia combined with acupuncture analgesia and group N, thirteen patients receiving usual neuroleptanesthesia without acupuncture. A significant difference was found in the dose of fentanyl, used as the narcotic, between group A (0. 11 mg) and group N (0. 48 mg). Anesthesia in combination with acupuncture is capable of reducing the required dose of narcotic and offers more comfortable postoperative conditions than usual anesthesia alone.
