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.",[59],"Traumatic Brain Injury",[61,62,63,64,65],"traumatic brain injury","craniocerebral trauma","brain trauma","intracranial pressure","transcranial Doppler ultrasound","NOT_YET_RECRUITING","2025-09-01",{"date":69,"type":70},"2025-09-03","ACTUAL",{"date":72,"type":55},"2025-09-15",{"date":74,"type":55},"2027-07-01",{"name":5,"class":6}]
