Minimal Flow Anesthesia (50% O2, 50% air), Desflurane (MAC = 4,5). In hypotensive anesthesia application; Remifentanil will be used at infusion rates of 0.025-0.1μg / kg / min after a loading dose of 1 μg / kg / min, with mean Arterial Pressure 55-65 mmHg.
Before the induction of anesthesia and 30 minutes of anesthesia, 2 ml of venous blood sample will be taken from the patients and simultaneous tissue oxygen saturation will be recorded. Serum thiol disulfide levels obtained from the blood sample of the recipient will be studied in the biochemistry research laboratory using the method developed by Erel et al.

Participants with ASA 1-2, aged 18-60 years, undergoing hypotensive anesthesia in the operation of the septoplasty in Recep Tayyip Erdoğan University Medical Faculty Training and Research Hospital. Participants with uncontrolled hypertension, diabetes mellitus, cerebrovascular disease, cogulopathy, morbid obesity (BMI ≥35) and renal disease will not be taken.
Participants were first pre-medicated with an infusion of midazolam 0.05 mg/kg, fentanyl 1 µg/kg, lidocaine 1 mg/kg. Induction of anesthesia was achieved with an infusion of propofol 1-2 mg/kg and vecuronium bromide 0.6 mg/kg and after 2 to 3 minutes participants were intubated with the appropriate tube size. Anesthesia was maintained with an infusion of remi fentanyl (0.05 - 1 µg/Kg/min), with oxygen (O2) in air with desflurane.
