Effect of ORI-guided Oxygen Titration on Oxidative Stress in Rhinoplasty Surgery
NCT07158073 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60
Last updated 2025-09-08
Summary
The aim of this study is to evaluate whether the use of Oxygen Reserve Index (ORİ) can prevent hyperoxia in patients undergoing rhinoplasty surgery and whether it can reduce oxidative stress caused by hyperoxia.
Conditions
- Rhinoplasty
- Oxidative Stress
- Hyperoxia
- Oxygen Reserve Index
Interventions
- DEVICE
-
FiO₂ titration, under the guidance of ORI
In Group R, FiO₂ was titrated between 30% and 50% under the guidance of ORI and SpO₂ values. Accordingly, if SpO₂ was ≥ 98%, FiO₂ was reduced in 5% increments to a minimum of 30%, aiming to achieve an ORI value of 0 or as close to 0 as possible.
- DEVICE
-
Conventional oxygen administration
In Group C, FiO₂ was maintained at 50% throughout the surgery, provided that SpO₂ remained ≥ 98%.
