Intraoperative Different Concentrations Oxygen And Oxidatıve Stress Markers

The Effects of Intraoperative Oxygen Used at Different Concentrations on Oxidatıve Stress Markers

The aim of the study was to assess the effect of intraoperative oxygen (O2), which was applied at 30% and 50% concentrations on patients who had undergone septoplasty surgery, on Total Oxidant Status (TOS), Total Antioxidant Status (TAS), and Oxidative Stress Index (OSI).

Inclusion Criteria:

• patients aged between 18-60 years,
• ASA I-II risk class with a minimum operative time of 1.5 hour(s) for whom septoplasty operation under elective conditions

Exclusion Criteria:

• metabolic, endocrine, hepatic, cardiac, or renal diseases,
• malignancies and who used a drug with antioxidant properties such as vitamin E-C
• acetylcysteine in the last 48 hours,
• patients requiring intraoperative 100% O2 inhalation
