About this trial
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.

Age ≥ 18 years
Patients classified as ASA physical status I-II-III
Patients scheduled for elective lumbar spine stabilization surgery under general anesthesia
Ability to obtain adequate inferior vena cava (IVC) ultrasonographic imaging
Disqualifiers
Age younger than 18 years

Trial population
Adult patients (≥18 years) scheduled for elective lumbar spine stabilization surgery under general anesthesia at Trabzon University Faculty of Medicine Hospital will be included in this study. All participants will be classified as ASA physical status I-II-III and will undergo surgery in the prone position. Inferior vena cava (IVC) diameter and collapsibility index will be measured using ultrasonography at predefined perioperative time points.

Inferior Vena Cava Collapsibility Index
The inferior vena cava (IVC) collapsibility index will be measured using ultrasonography at predefined perioperative time points (preoperative period, after induction of general anesthesia, and before extubation) in patients undergoing elective lumbar spine surgery in the prone position.

Perioperative period (preoperative assessment, after anesthesia induction, and before extubation)Secondary outcomes

Intraoperative Hypotension Incidence
The occurrence of intraoperative hypotension during lumbar spine surgery under general anesthesia will be recorded. Hypotension will be defined as mean arterial pressure below 65 mmHg.
