SV and IVC Collapsibility Index to Predict Postinduction Hypotension

Stroke Volume Versus Inferior Vena Cava Collapsibility Index to Predict Postinduction Hypotension in Intestinal Obstruction

Source: ClinicalTrials.gov · Last updated 10 Sept 2026

Brief summary (registry, in English)

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.
