Oxygenation in Posterior Stabilization Surgery

Starting soon

Conditions studied: Oxygen, Oxygen Saturation

In brief

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.
