AimsIn this study, we aimed to investigate the anti-inflammatory and antioxidant effects of intravenous ibuprofen by using the C-reactive protein level and thiol/disulfide homeostasis as the oxidative stress marker.Materials And MethodsThis study was conducted on 70 patients aged between 30 and 65 who were scheduled for elective laparoscopic hysterectomy. The patients were divided into two groups to receive either pre-emptive 800mg of intravenous ibuprofen plus 1000 mg of intravenous paracetamol (Group IP) or only 1000 mg of intravenous paracetamol as a control group (Group P). The blood samples for thiol/disulfide homeostasis were collected as follows: before induction of anesthesia (T0), before pneumoperitoneum (T1), following postdeflation and discontinuation of anesthesia (T2), and postoperative 24th hour (T3). Simultaneous blood samples for C-reactive protein (CRP) were also collected. The pre- and postoperative urea, creatinine, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels were measured.ResultsA total of 69 patients were included in the study. The patient's characteristics and intraoperative variables were comparable between groups (P > .05). The number of patients requiring rescue analgesia, the total amount of analgesic used, Visual Analog Scale (VAS) scores, and postoperative side effects were significantly lower in Group IP (P < .001). The decrease in native and total thiol levels at T1, T2, and T3 measurement points was significant in Group IP (P < .001). In both groups, the comparison to baseline values demonstrated no significant changes in terms of disulfide level (P > .05). The simultaneous CRP levels indicated a significant increase at the postoperative 24 hour in both groups (P < .001). The difference between groups was insignificant (P > .05). There was a significant increase in urea and creatinine levels in patients of Group IP (P < .05).ConclusionThe pre-emptive administration of ibuprofen provided effective pain control after gynecologic laparoscopy. However, ibuprofen changed the thiol/disulfide homeostasis in favor of oxidation and had no beneficial effect in surgically induced oxidative stress.© 2021 John Wiley & Sons Ltd.
