简要总结
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 hemodynamic changes during lumbar spine surgery.
详细描述
his prospective study aims to evaluate perioperative hemodynamic changes using the inferior vena cava (IVC) collapsibility index in patients undergoing lumbar stabilization surgery under general anesthesia in the prone position. The inferior vena cava diameter will be measured using ultrasonography at different perioperative time points, including the preoperative period, after induction of anesthesia, and before extubation.
The IVC diameter and collapsibility index will be recorded and analyzed to assess changes in intravascular volume status during the perioperative period. In addition to ultrasonographic measurements, hemodynamic parameters such as blood pressure and heart rate will be monitored and recorded.
The study aims to investigate whether the IVC collapsibility index can be used as a non-invasive indicator of intravascular volume status and perioperative hemodynamic changes in patients undergoing lumbar spine surgery.

研究组 & 干预措施
Patients Undergoing Lumbar Spine Surgery
Adult patients undergoing elective lumbar spine stabilization surgery under general anesthesia in the prone position. Inferior vena cava (IVC) diameter and collapsibility index will be measured using ultrasonography at predefined perioperative time points (preoperative period, after induction of anesthesia, and before extubation). Hemodynamic parameters such as blood pressure and heart rate will also be recorded.
