Effect of Transcutaneous Acupoint Electrical Stimulation on Postoperative Spontaneous Voiding for Laparoscopic Patients

"In the acupoints group patients are treated with low-frequency pulse electroacupuncture stimulation apparatus (HANS G6805-2, Huayi Co, Shanghai, China) at SP6 and BL 32 points during the operation in the operating room ,and at CV3 and CV4 acupoints for 45 minutes in postanesthesia Care Unit. After Deqi, electroacupuncture stimulation apparatus is connected with the density wave (2/100 Hz), width 0.25 ms, intensity of 1 \~ 30 milliamp (mA) (gradually increase to the patient's maximum tolerance) and maintained until the end of treatment."

"Participants in the acupoints group receive shallow acupointing at SP6, BL 32 ,CV3 and CV4 (nonacupoints located 1 inch beside acupoints, about 20mm).Specifically, the acupoint is shamed without manual stimulation and Deqi and the stimulation apparatus is inefficiency without actual current output ."
