U.S., April 24 -- ClinicalTrials.gov registry received information related to the study (NCT07549165) titled 'IVC Collapsibility Index in Lumbar Stabilization Surgery' on April 17.
Brief Summary: This study aims to evaluate perioperative hemodynamic changes using the inferior vena cava (IVC) collapsibility index in patients undergoing lumbar stabilization surgery under general anesthesia. The IVC diameter and collapsibility index will be measured using ultrasonography at predefined perioperative time points. Hemodynamic parameters such as blood pressure and heart rate will also be recorded. The study seeks to determine whether the IVC collapsibility index can be used as a non-invasive indicator of intravascular volume status and hemodynami...
