Groups have been randomyl divided; group P (pethidine) (n: 50), group PK (pethidine with ketamine) (n: 50), 100 patients in ASA I-II have been included in the study. Maintenance of general anaesthesia with O2/N2O/Sevoflurane and fentanylas opioid have been used. In the postoperative period in group P; loading dose: 50 mg, basal infusion 1 mg/hr, bolus dose 5 mg, lock-out time: 15 min have been programmed andin the group PK 2.5 μgr/kg/min of ketamine have been added into the same programe. During yhis application, VAS (Visual Analoge Scale), sedation sscore (SS), heart rate (HR), respiration rate (RR), value of analgesic demanded, cumulative drug consumption and side effects have been recorded in the postoperative 30th min, 2nd, 6th, 12th and 24th hours.
