Background: Incoming anaesthesia created by the use of many drugs with different physicochemical properties is a sourceof stress and trauma for the body. This event increases the oxidative response and changes the balance between oxidant/antioxidant capacity in the organism in favor of oxidant capacity. This situation is defined as oxidative stress. For thesereasons, studies are conducted to determine the effects of general anaesthetic agents on oxidant and antioxidant systems inthe organism. In this study, it was aimed to determine the effects of isoflurane and sevoflurane used for general anaesthesiain humans and animals on lipid peroxidation and antioxidant defense system in calves.Materials, Methods & Results: The study included 14 calves of different breeds, ages, sexes, and weighing, average 2 weeksold. The cases randomly were divided into 2 groups, the isoflurane group (group I), and the sevoflurane group (group II),and each group included 7 animals. Before general anaesthesia, 0.04 mg/kg atropine was administered intramuscularly toall animals for premedication. At 15 min after atropine administration, isoflurane was administered at an inspiratory concentration of 3-5% in group I, and sevoflurane was administered at an inspiratory concentration of 5-7% in group II, via aface mask for 15 min for the induction of anaesthesia. Endotracheal intubation was performed in all cases at the 15 min ofthe induction period following the onset of general anaesthesia symptoms. After the induction, anaesthesia was continuedat an inspiratory concentration of 1.5-3% in the isoflurane group and inspiratory concentration of 2.5-4% in the sevofluranegroup. Blood samples were taken just before anaesthesia, just before skin incision, at the end of anaesthesia and surgery,and at the 24 h postoperatively.
