Assessment of ONSD, ODE and the Crescent Sign Using POCUS
Conditions
Keywords
POCUS, ONSD, ODE, crescent sign
Brief summary
Our aim was to determine the diagnostic accuracy of the ONSD, ODE, and crescent sign, as detected by POCUS, in identifying the clinical and radiological features of increased intracranial pressure.
Detailed description
All participants presenting to the ED with various symptoms and undergoing cranial CT or MRI for the diagnosis of cranial pathologies who do not meet the exclusion criteria will be included in the study. Informed consent will be obtained from all patients prior to the study. For participants included in the study, the presence of ONSD, ODE, and the crescent sign will be assessed using bedside ultrasound, and the diagnostic value of these findings will be evaluated. The bedside ultrasound will form part of the critical area examination in the emergency department; it will incur no cost to the institution and will be performed and assessed by an emergency medicine specialist and their assistant.
