[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] ABSTRACT: To observe the impacts of transcutaneous acupoint electric stimulation on hemodynamics, anesthetic and relevant complications in patients of transsphenoidal pituitary tumor resection (TPTR).
Ninety cases of the selective TPTR were randomized into a transcutaneous acupoint electric stimulation group (group T), a sham-acupoint group (group S) and a control group (group C); 30 cases in each one. In group T, the transcutaneous acupoint electric stimulation at Hegu (LI 4), Waiguan (TE 5), Jinmen (BL 63), Taichong (LR 3), Zusanli (ST 36) and Qiuxu (GB 40). In group S, the transcutaneous acupoint electric stimulation was applied to the sham-acupoints. In group C, the acupoints selected were same as those in group T, but the electrode pads were just attached on the related points with no-electric stimulation. The electric stimulation lasted from analgesic induction till the end of the operation. The endotracheal intubation was done under the induction by propofol, fentanyl and vecuronium bromide. Propofol and remifentanil were maintained till the end of operation. Blood pressure, heart rate, bispectral index (BIS) value, anesthetic and postoperative recovery situation were recorded.
The hemodynamics maintained stably in each group. In group T, the mean arterial pressure 1 min after intubation, after extubation and during directional force recovery was all lower than the other two groups respectively (all P<0.05). In group T, the effect-site concentration of fentaryl in the exposure saddle area and tumor removal stage was lower than the other two groups (all P<0.05). In 24 h after operation, 2 cases presented nausea and vomiting in group C. There were no relevant complications in the rest groups.
The transcutaneous acupoint electric stimulation improves the stability of hemodynamics in perioperative stage, reduces the intraoperative opi oids dosages and improves the quality of anesthetic recovery.

[Show abstract][Hide abstract] ABSTRACT: To observe the effects of electro-acupuncture combined with sevoflurane anesthesia used in neurosurgery patients and the speed of recovery following surgery.
Eighty patients with supratentorial tumor resection were anesthetized with sevoflurane and randomly allocated into the complete anesthesia group (Group A) and the electro-acupuncture combined with sevoflurane group (Group B). Han's acupoint nerve stimulator with 2/100 Hz frequency was used to stimulate the points. Patients in Group B received electroacupuncture at Fengchi (GB20) toward Tianzhu (BL10) and Cuanzhu (BL2) toward Yuyao (EX-HN4) at the same side of the craniotomy before anesthesia induction. The stimulation was lasted from anesthesia induction until the end of operation. Patients in Group A were pasted with the conducting wire at the aforesaid points, but with no acupuncture or electric stimulation. All patients were induced with propofol 2 mg/kg, sufentanyl 0.3 microg/kg, and vecuronium 0.1 mg/kg, and maintained anesthesia with 2% sevoflurane. The bispectral index (BIS) was maintained ranging 40 -50. The sevoflurane was stopped inhaling at the end of the operation. The end-tidal sevoflurane concentration, minimum alveolar concentration (MAC), BIS, and the anesthesia recovery at each time point were recorded in the two groups.
There was no statistical difference in the mean arterial pressure or the heart rate. The end-tidal concentration and MAC of sevoflurane were significantly lower in Group B than in Group A at each time point (P<0.05). The dose of sevoflurane was reduced by 8.34% +/- 1.24% in Group B when compared with that of Group A. The BIS value could be maintained ranging 40 - 50 in both groups, thus guaranteeing the anesthesia depth. The time for the spontaneous respiration recovery, the extubation time, the time for opening eyes, the time for the voluntary movement recovery, and the time for orientation recovery, and the time for leaving the operation room were significantly shorter in Group B than in Group A (P<0.01). The occurrence of dysphoria, nausea and vomiting was less in Group B than in Group A.
Electro-acupuncture combined with sevoflurane used in neurosurgery could save the dose of sevoflurane, significantly shorten the anesthesia recovery time, and improve the quality of the anesthesia recovery. It was a favorable anesthesia method.

[Show abstract][Hide abstract] ABSTRACT: To observe the effect of electroacupuncture (EA) of different acupoint groups on the sevoflurane anesthetic requirement for resection of supratentorial tumors and the speed of post-operation recovery.
A total of 120 cases of supratentorial tumor resection patients were randomly and equally allocated into general anesthesia (GA) group, EA-proximal acupoints group (EA-PA group) and EA-distant acupoints group (EA-DA group). The supratentorial tumor patients were anesthetized with sevoflurane for surgery. Proximal acupoints used were Fengchi (GB 20), Tianzhu (BL 10), Cuanzhu (BL 2) and Yuyao (EX-HN 4) that the former 2 acupoints and the latter 2 acupoints were for penetrative needling; and distant acupoints used were Hegu (LI 4), Waiguan (TE 5), Jinmen (BL 63), Taichong (LR 3), Zusanli (ST 36) and Qiuxu (GB 40) on the craniotomy side, and stimulated with EA (2 Hz/100 Hz, a tolerable electric stimulating strength), beginning from the anesthesia induction till the end of surgical operation. All patients were anesthetized by inhalation of propofol (2 mg/kg), sufentanil (0.3 microg/kg) and vecuronium bromide (0.1 mg/kg) and maintained with sevoflurane. The end-tidal sevoflurane concentration, minimum alveolar concentration (MAC), bispectral index (BIS), and the speed of recovery were recorded.
In comparison with the GA group, the end-tidal concentrations during anesthesia maintenance at the time-points of post skull drilling, dura incising, intracranial operation in EA-PA group, the time-points of post skull drilling, skull opening, dura incising, and intracranial operation in EA-DA group, and the MAC of sevoflurane at the time-points of skull drilling in EA-DA group, and skull opening, dura incising, intracranial operation and dura suturing in both EA-PA and EA-DA groups were significantly lower (P < 0.05, P < 0.01). Compared to the GA group, the BIS values of EA-DA group at the time-points of skull drilling and opening, and dura incising were significantly higher (P < 0.05), while during the recovery stage of anesthesia, in comparison with the GA group, the autonomous respiration recovery time, tracheo-tube removing time, eye-opening time, voluntary motion recovery time, orientation force recovery time, and operating room-departure time of both EA-PA and EA-DA groups were significantly shorter (P < 0.05, P < 0.01). No significant differences were found between the EA-PA and EA-DA groups in the aforementioned indexes (P > 0.05).
EA of both proximal and distant acupoints can reduce the expired concentration and MAC of sevoflurane during anesthesia maintenance, and accelerate the recovery after cease of anesthesia in supratentorial tumor resection patients.

[Show abstract][Hide abstract] ABSTRACT: To observe the supplementary analgesic effect of electroacupuncture and its influence on the maintenance of anesthesia and the speed of recovery of patients undergoing craniotomy.
Eighty cases of supratentorial tumor resection were randomly divided into group A and group S, 40 cases in each group. All the patients were anesthetized with 2% Sevoflurane. The patients in group A received electroacupuncture at Hegu (LI 4) and Waiguan (TE 5), Jinmen (BL 63) and Taichong (LR 3), Zusanli (ST 36) and Qiuxu (GB 40) from anesthesia beginning to the end of operation, and in group S without electroacupuncture. The end-tidal Sevoflurane concentration, minimum alveolar concentration (MAC), bispectral index (BIS) and the information during anesthesia recovery stage were recorded, respectively.
The end-tidal concentration and MAC of Sevoflurane in group A at all times were significant lower than those in group S (P<0.05, P<0.01) with a Sevoflurane saving of 9.62% on average. The BIS in group A during a few phases were higher than that in group S (all P<0.05). During anesthesia recovery stage, the time of each phase in group A was significantly shorter than that in group S (all P<0.01). No dysphoria and one case with nausea and vomiting were shown in group A, but in group S, 2 patients had dysphoria and 3 patients had nausea and vomiting.
Electroacupuncture combined with Sevoflurane anesthesia can decrease the dosage of Sevoflurane, shorten the recovery time of anesthesia and improve the quality of anesthesia recovery of the patients undergoing resection of supratentorial tumor.
