Description In Group A, the acupuncture needles (0.25×40 mm) wereinserted into acupoints at LI4 (Hegu), SJ5 (WaiGuan), BL63 (JinMen), LR3 (Tai-Chong), ST36 (ZuSanLi) and GB40 (QiuXu) on the same side as the craniotomy. For LI4, SJ5, BL63, LR3, ST36, and GB40, each acupuncture point was treated with oneneedle. LI4 and SJ5, BL63 and LR3, as well as ST36 and GB40, were connected inpairs to the acupuncture point nerve stimulator.
Experimental Description
Eighty-eight patients requiring a supratentorial tumor resection were anesthetized with sevoflurane and randomly allocated to a no treatment group (Group C) or an EA group (Group A).

Auxiliary Medication
Following pre-oxygenation, anesthesia was induced in both groups with an IV infusion of sufentanil 0.3 g/kg and propofol 2 mg/kg. A tracheal intubation was facilitated with IV vecuronium 0.1 mg/kg. General anesthesia was initially maintained with sevoflurane, 2% in oxygen at 2L/min. At the end of the operation, sevoflurane was discontinued and the intravenous PCIA pump was connected. The PCIA device was programmed and contained 10 g/kg fentanyl and 8 mg ondansetron with normal saline for a total of 100 mL without basal infusion. Supplemental bolus doses of 1 mL could be administered with a minimal lockout interval of 15 min and a maximum hourly dose of 4 mL if the patient was unable to achieve adequate pain relief from the PCIA device.

Description EA stimulation was delivered via a LH202H HANS acupuncture point nerve stimulator (Beijing Huawei Co Ltd; Beijing, China) using a dense-dispersed wave with frequencies of 2 and 100 Hz alternating every 3 s. The waveform was a symmetric biphasic curve. The stimulation intensity was set to the level of maximum tolerance for each patient, and the stimulation lasted from the induction of anesthesia until the end of the operation.

Clinical Trial Type
random
Contraindications
All the patients underwent a needling test before they were included in the study to exclude subjects who were resistant to acupuncture. Patients were also excluded if they developed a postoperative hematoma or infection
Effector
In the first 6 hours after the operation, the mean total bolus, the effective times of PCIA bolus administrations and the VAS scores were much lower in the EA group (p < 0.05). In the EA group, the incidence of PONV and degree of dizziness and feeling of fullness in the head within the first 24 hours after the operation was much lower than in the control group (p < 0.05). In the EA group, more patients had a better appetite than did the patients in group C (51.2% vs. 27.5%) (p < 0.05). The use of EA in neurosurgery patients improves the quality of postoperative analgesia, promotes appetite recovery and decreases some uncomfortable sensations, such as dizziness and feeling of fullness in the head.
Electro-acupuncture decreases postoperative pain and improves recovery in patients undergoing a supratentorial craniotomy.
Abstract
We performed this study to examine the effect of electro-acupuncture (EA) on postoperative pain, postoperative nausea and vomiting (PONV) and recovery in patients after a supratentorial tumor resection. Eighty-eight patients requiring a supratentorial tumor resection were anesthetized with sevoflurane and randomly allocated to a no treatment group (Group C) or an EA group (Group A). After anesthesia induction, the patients in Group A received EA at LI4 and SJ5, at BL63 and LR3 and at ST36 and GB40 on the same side as the craniotomy. The stimulation was continued until the end of the operation. Patient-controlled intravenous analgesia (PCIA) was used for the postoperative analgesia. The postoperative pain scores, PONV, the degree of dizziness and appetite were recorded. In the first 6 hours after the operation, the mean total bolus, the effective times of PCIA bolus administrations and the VAS scores were much lower in the EA group (p < 0.05). In the EA group, the incidence of PONV and degree of dizziness and feeling of fullness in the head within the first 24 hours after the operation was much lower than in the control group (p < 0.05). In the EA group, more patients had a better appetite than did the patients in group C (51.2% vs. 27.5%) (p < 0.05). The use of EA in neurosurgery patients improves the quality of postoperative analgesia, promotes appetite recovery and decreases some uncomfortable sensations, such as dizziness and feeling of fullness in the head."
