About this study
Official title: Evaluation of the Effect of Cerebrospinal Fluid Drainage on Optic Nerve Sheath Diameter in Patients Installed External Ventricular Drainage Catheter Due to Intracranial Pathology in the Intensive Care Unit
Determination of high intracranial pressure (ICP) is necessary for the treatment of patients with raised ICP to improve long-term neurological outcomes. Ultrasonographic optic nerve sheath diameter (ONSD) measurement is a noninvasive, easily performed and cost effective technique for detecting high ICP.
Read the detailed description
ICP measurements via ventricular catheters provide CSF drainage and ICP reduction. The normal ICP value is less than 15 mmHg in adults. In the literature the correlation of ONSD and invasive ICP measurements were determined. The aim of study is to evaluate the correlation of ONSD and direct ICP measurements and to determine cut off ONSD value to detect ICP ≥15 mmHg.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Intracranial Pressure-1 (ICP-1) (time frame: baseline time). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06367868, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2024; AzTrials last refreshed its copy on 7 Nov 2026.
