NCT07151287

Brief Summary

The goal of this observational study is to investigate several means of measuring intracranial pressure (ICP) non-invasively in patients who had head trauma and received implantation of invasive ICP monitor device. The main questions it aims to answer are: What are the diagnostic efficacies of Transcranial Color-Coded Doppler Ultrasound (TCCD), Optic Nerve Sheath Diameter (ONSD) and Optic Disc Height (ODH) (the 3 non-invasive way of measuring ICP) compared with invasive ICP monitor? Participants will receive simultaneous non-invasive measurements of TCCD, ONSD and ODH along with during the days of invasive ICP monitoring. The data will be compared among the techniques to study the diagnostic efficacy.
