NCT05818371

Brief Summary

Intensive care patients with established invasive intracranial neuromonitoring due to neurotrauma are subjected to a repeated non-invasive sonographic recording of the optic-nerve-sheath-diameter (ONSD). The recorded images are analyzed through a machine-learning-algorithm and an experienced ultrasound operator. Results are correlated to the parallel recorded intracranial pressure (ICP). The study aims to establish ONSD as a supplementary for raised ICP.
