Effects of TIVA and Inhalation Anesthesia on Oxidative Stress Factors During Hypotensive Anesthesia

"Ventilation of the patients was provided with a mixture of 40% oxygen and 60% air. Along with induction, propofol at a dose of 6-10 mg/kg/hour and remifentanil infusion at a dose of 0.3-0.4 mcg/kg/min were started for the maintenance of anesthesia. Drug concentrations were adjusted to maintain BIS values between 40-60 in the maintenance of anesthesia.~The MAP target was determined to be in the range of 50-65 mmHg. Blood was collected and stored to measure TAS, TOS, Catalase, Myeloperoxidase, Total Thiol, Native Thiol and Disulfide parameters before and after induction at 5,30,60 and 120 minutes. Hemodynamic data (HR, SBP, DBP, MAP, SpO2) and BIS values of the patients were recorded at 5-minute intervals. The extubation time was recorded. The surgical field opinion and satisfaction assessment were made by Boezaart Scoring and the survey presented to the surgeon, respectively. The patients were followed up for 30 minutes; numerical pain scores and nausea-vomiting scores were recorded"

"Ventilation of the patients was provided with a mixture of 40% oxygen and 60% N2O. As soon as mechanical ventilation started, sevoflurane was opened at a concentration of 2-3% with a MAK value of 1.1-1.3. Drug concentrations were adjusted to maintain BIS values between 40-60 in the maintenance of anesthesia.~The MAP target was determined to be in the range of 50-65 mmHg. Blood was collected and stored to measure TAS, TOS, Catalase, Myeloperoxidase, Total Thiol, Native Thiol and Disulfide parameters before and after induction at 5,30,60 and 120 minutes. Hemodynamic data (HR, SBP, DBP, MAP, SpO2) and BIS values of the patients were recorded at 5-minute intervals. The extubation time was recorded. At the end of the surgery, the surgical field opinion and satisfaction assessment were made by Boezaart Scoring and the survey presented to the surgeon, respectively. The patients were followed up for 30 minutes; numerical pain scores and nausea-vomiting scores were recorded."
