Internal Jugular Vein Collapsibility Index for Predicting Post-Induction Hypotension
Sponsor: University of Gaziantep
Summary
This study aims to investigate whether the Internal Jugular Vein Collapsibility Index (IJV-CI), measured via ultrasonography, can predict hypotension (low blood pressure) that occurs after the induction of general anesthesia. Researchers will measure the diameter of the internal jugular vein in patients before surgery and compare these measurements with the blood pressure changes during the first minutes of anesthesia. The goal is to determine if IJV-CI can be used as a reliable, non-invasive tool to identify patients at higher risk of developing anesthesia-induced hypotension.

Interventions
IJV-CI Measurement
Pre-induction Internal Jugular Vein (IJV) measurement will be performed using a linear ultrasound probe (5-12 MHz) while the patient is in the supine position. The IJV will be imaged in the transverse plane at the level of the cricoid cartilage. During spontaneous breathing, the maximum and minimum diameters of the vein will be recorded. The Collapsibility Index (IJV-CI) will be calculated using these measurements. This non-invasive assessment is performed immediately before the induction of general anesthesia to evaluate its predictive value for post-induction hypotension.
