Electroacupuncture in the Treatment of Patients Undergoing Transperineal Prostate Biopsy Under Local Anesthesia

Sterile acupuncture needles (Huatuo brand, specification: 0.25mm\*40mm) were applied to Hegu (Li4), Neiguan (PC 6), Guanyuan (CV 4) and Sanyinjiao (SP 6) by twidling, rotating, lifting and thrusting for 30 seconds. After getting qi (a feeling of acid, numbness, weight and swelling), the electronic acupuncture instrument (SDZ-II type, Huatuo brand) was connected, and the continuous wave was 50HZ. The current intensity was 1-5mA (preferably as much as the patient could tolerate without pain).

Sham electroacupuncture was applied at the non-meridian and non-acupoint sites 3mm apart from the acupoints in the experimental group. The acupuncture method was shallow acupuncture, only 1-4mm through the skin.
