Internal Jugular Vein Collapsibility Index for Predicting Post-Induction Hypotension
Starting soon
Conditions studied: Hypotension, Anesthesia, General, Cholecystectomy, Laparoscopic
In brief
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.
