"Five minutes before infiltration of the local anesthestic by the surgeon, patients received an initial maintenance infusion of remifentanil 0.1 µg/kg/min and ketofol mixture 0.3 ml/kg (propofol 25 µg /kg/min and ketamine 10 µg/kg/min). ketofol mixture was prepared in a ratio of 1:2.5 (100 mg ketamine 2 mL (100 mg), propofol 1% 25 mL (250 mg), and glucose 5% 23 ml, total volume of 50 ml, each ml contain 2 mg ketamine + 5 mg propofol).~Throughout the surgery, titration of the infusion rate of the remifentanil and ketofol were indicated by vital signs and expression of pain"

general anesthetic was induced with a bolus dose of remifentanil (1 ug/kg over 30 second) and propofol (2 mg/kg) followed by insertion of a laryngeal mask airway (LMA). After the induction of anaesthesia and securing the airway, patient' lungs were ventilated with volume controlled ventilation, 50% oxygen/air mixtures in a circle system. .Anesthesia was maintained with remifentanil (0.5 ug/ kg/ min) and propofol (5 mg/kg/h). Remifentanil and propofol titrated to keep heart rate and the blood pressure within 20% of the baseline values and maintain BIS between 40 and 60, respectively. Patient movements were treated with additional i.v. bolus doses of remifentanil 0.5 ug/kg
