Auxiliary Medication
All patients were premedicated with oral diazepam 0.2 mg kg-1 2 h before anaesthesia. Pethidine 1.5 mg kg-1 i.v. was given and anaesthesia induced with propofol 1.2-1.5 mg kg-1 i.v. Tracheal intubation was facilitated by administration of vecuronium 0.1 mg kg-1. Ventilation was controlled manually and anaesthesia maintained with 66 % nitrous oxide in oxygen, continous infusion of propofol 4-8 mg kg-1 h-1; pethidine 0.5 mg kg-1 was given before skin incision and thereafter as required, at the discretion of the anaesthetist.

Effector
On the basis of this study, it is obviously seen that acupuncture could: decrease the incidence of morphine-related side effects (nausea and vomiting, itchiness and gastrointestinal disorders) when the spinal cord conduct is normal. However, it decreases only the incidence of itchiness but not for gastrointestinal dysfunction when the spinal cord is blocked.
Electroacupuncture in anaesthesia for hysterectomy.
Abstract
We have studied the effects of electroacupuncture at classical acupuncture points, applied before and during surgery in patients undergoing hysterectomy, on postoperative pain and metabolic stress responses in a prospective, randomized and patient-blinded manner. Fifty otherwise healthy women were allocated randomly to receive or not receive electroacupuncture. Electroacupuncture was begun 20 min before skin incision and continued to the end of surgery. All patients received similar general anaesthesia and all received patient-controlled analgesia (PCA) after operation. Postoperative pain in the two groups was evaluated by recording analgesic requirements by PCA and by pain-rating performed by patients and nursing staff. There were no significant differences between the two groups in postoperative analgesic requirements, pain-rating or metabolic stress responses."
