Ultrasound Measurement of Optic Nerve Sheath Diameter as Non-Invasive Detector of Raised Intracranial Pressure in Adult Traumatic and Non-Traumatic Neurocritical Patients in ICU

Ain Shams University50 enrolled

Overview

This study aimed to assess the role of ultrasound as a non-invasive method (bedside) to measure the rise of intracranial pressure by measuring the optic nerve sheath diameter in traumatic and nontraumatic neurocritical patients.

Measurement of intracranial pressure (ICP) is crucial in the management of many neurological conditions. However, due to the invasiveness, high cost, and required expertise of available ICP monitoring techniques, many patients who could benefit from it do not receive it. As a result, a substantial effort has been made to explore and develop novel non-invasive ICP monitoring techniques to improve the overall clinical care of patients suffering from ICP disorders.
