NCT07742904

Overview

NCT ID: NCT07742904
Lead Sponsor: Ain Shams UniversityOTHER
Official Title: Stroke Volume Versus Inferior Vena Cava Collapsibility Index to Predict Postinduction Hypotension in Intestinal Obstruction
Brief Summary: Postinduction hypotension (PIH) is a frequent complication during general anesthesia. This study aims to compare the predictive effectiveness and diagnostic accuracy of stroke volume (SV) measured via left ventricular outflow tract velocity time integral (LVOT-VTI) versus the inferior vena cava collapsibility index (IVC-CI) using transthoracic echocardiography. The assessment will be conducted in adult patients with intestinal obstruction undergoing exploratory abdominal surgery under general anesthesia.
Conditions: Post-induction Hypotension
Intestinal Obstruction

Ages Eligible for Study: Adult (18-64)Older Adult (65+)
