Objective: The aim of this study is to evaluate whether the exposure of oxidative stres in the peroperative period and the postoperative 24th hour can be decreased with the thiol-disulfide homeostasis (TDH) method and C-Reactive Protein (CRP) with intravenous ibuprofen used for postoperative analgesia in patients undergoing total laparoscopic hysterectomy Material and Method: Sixty-nine patients with American Society of Anesthesiologists (ASA) scores I and II who scheduled for laparoscopic hysterectomy were included in the study. The patients were randomly divided into two groups as ibuprofen and paracetamol (Group IP) and paracetamol (Group P) with the sealed envelope method. When the vascular access was established from all patients (T0), after blood was drawn for TDH and CRP measurements, while 30-minute lasting iv infusion of 800 mg ibuprofen diluted with 0,9% isotonic and iv infusion of 1 g paracetamol was started simultaneously, only 1g of paracetamol infusion was administered in Group P. In the IP group 800 mg ibuprofen and 1 g paracetamol, in the P group only paracetamol, the medicines specified for each group administered intravenously every 6 hours. The postoperative pain level in the patients was evaluated at the 1st, 2nd, 6th, 12th and 24th hours with the Visual Analogue Scale (VAS). Rescue analgesia with 1mg/kg tramadol as an iv bolus was applied to patients whose VAS score was 4 and above. Other blood samples for CRP and TDH were taken before insufflation (T1), after desufflation (T2) and at the postoperative 24th hour (T3). Demographic and hemodynamic data of the patients, duration of anesthesia and Trendelenburg position, need for additional analgesia, presence of nausea and vomiting, VAS scores, pathology results, CRP and TDH levels were recorded.
