About this trial
This study aims to evaluate the effects of prone positioning on oxygenation, ventilation, and hemodynamic parameters in patients undergoing posterior stabilization surgery under general anesthesia. By comparing routine anesthesia and monitoring data obtained in the supine and prone positions, the study seeks to determine how positional changes influence respiratory mechanics and perioperative physiological stability.

Trial outcomes
Primary outcomes
1
Change in alveolar oxygenation between supine and prone positions
The primary outcome of this study is to evaluate the difference in alveolar oxygenation between the supine and prone positions in patients undergoing posterior stabilization surgery. Arterial blood gas samples obtained during surgery will be used to compare oxygenation parameters measured in both positions and to assess the effect of positional change on oxygenation.
Time frame
within 20 minutes after anesthesia inductionSecondary outcomes
1
Change in optic nerve sheath diameter between supine and prone positions
The secondary outcome is the comparison of optic nerve sheath diameter measurements obtained in the supine position and after positioning the patient prone during posterior stabilization surgery. This assessment is intended to evaluate the effect of positional change on optic nerve sheath diameter.
