Auxiliary Medication
Pethidine 30 mg was given intravenously 15 minutes after the start of stimulation. Further small doses of pethidine together with a small dose of chlorpromazine were given intravenously if the arterial blood pressure and/or heart rate increased by more than 25% during surgery; in some cases procaine was infiltrated into the wound. The dose of pethidine did not exceed 1 mg/kg.

Description Four ear points on the same side as the thyroid adenoma were selected for puncture (Table 1, Fig. 1). The needles were connected to a battery-powered G-6805 acu-stimulator whose output could be varied arbitrarily from 0-4. Stimuli at a rate of 4 Hz were applied and the strength gradually increased to the limits of the patients' tolerance. The maximum amplitude reached was setting 3 in all cases, which resulted in a current up to 20 mA and voltage up to 20 volts.
Anesthesia Method
AAA
Clinical Trial Type
Effector
There were significant increases in mean arterial pressure and respiratory rate during surgery, but no significant change in heart rate. The mean dose of pethidine given during surgery was 45 mg (SD 8.9). Postoperative recovery was rapid and complication free. Acupuncture anaesthesia did not provide complete analgesia, but was safe and preferable to general anaesthesia where there was a shortage of facilities.

Abstract
Acupuncture anaesthesia, supplemented by small doses of pethidine, was evaluated in 20 patients who had surgery for removal of a thyroid adenoma. There were significant increases in mean arterial pressure and respiratory rate during surgery, but no significant change in heart rate. The mean dose of pethidine given during surgery was 45 mg (SD 8.9). Postoperative recovery was rapid and complication free. Acupuncture anaesthesia did not provide complete analgesia, but was safe and preferable to general anaesthesia where there was a shortage of facilities."
