Transorbital Sonography for Early Prognostication of Hypoxic‐Ischemic Encephalopathy After Cardiac Arrest

Abstract

Early and reliable prognostication of outcomes in patients with HIE can be simplified by ONSD values gathered with the use of TOS. Main advantages compared to other established markers are prognostication within the first 24 hours and independence from therapy with hypothermia. A higher level of accuracy can be reached by combining computed tomography (gray-to-white matter ratio values) and ONSD values.
