Ultrasound-Guided Evaluation of Volume Status: Comparing IVC Collapsibility and Caval Aorta Indices in Predicting Anesthesia-Induced Hypotension in Geriatric Surgical Patients"

Abstract

Background: Elderly patients undergoing surgical procedures are at increased risk of perioperative 
hypotension due to age-related physiological changes and the effects of central neuraxial blockade 
(CNB). Accurate preoperative assessment of intravascular volume status is critical to predict and 
prevent hypotension. This study aimed to compare the efficacy of the inferior vena cava collapsibility 
index (IVCCI) and the IVC-to-aorta (IVC:Ao) index in predicting anesthesia-induced hypotension in 
geriatric surgical patients.
