Trial summary

Increased intracranial pressure is a cause of disease progression in patients with brain disease, a common cause of poor prognosis. Intracranial pressure monitoring is the observation of the disease, treatment, evaluation and important way to improve the prognosis. Read more about this study

About this study

Increased intracranial pressure is a cause of disease progression in patients with brain disease, a common cause of poor prognosis. Intracranial pressure monitoring is the observation of the disease, treatment, evaluation and important way to improve the prognosis. Non-invasive intracranial pressure monitoring can be used to stroke, intracranial hemorrhage, brain trauma, encephalitis and other patients. Ophthalmic artery originated from the internal carotid artery, the optic canal into the orbit, the entire process can be divided into intracranial optic tube segment and orbital segment. investigators' preliminary experiments show that when intracranial pressure, intracranial ophthalmic artery segment velocity increases with increasing velocity difference orbital segment. Accordingly, the investigators speculate, may be judged by the level of intracranial pressure intracranial and orbital velocity difference between the ophthalmic artery segment, and accordingly calculate the specific values of intracranial pressure. The investigators will collect brain trauma surgery, performed invasive intracranial pressure monitoring cases, the use of transcranial Doppler ultrasound velocity and different segments of the ophthalmic artery pulsatility index, the invasive intracranial pressure and comparing the measured values to calculate the the critical value of the ophthalmic artery segment intraorbital and intracranial velocity difference when intracranial pressure, thus fitting Based on projections of mathematical formulas intracranial pressure. This study will provide a non-invasive intracranial pressure monitor new approach.

Questions about this trial

What is this clinical trial studying?

An observational study of Traumatic Brain Injury and Cerebral Hemorrhage, run by Shanghai Jiao Tong University Affiliated Sixth People's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Feb 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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?

Ophthalmic artery blood flow rate changes associated with intracranial pressure (time frame: "up to 6 months"). 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 NCT02240394, which also lists 1 linked publication.

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 11 Feb 2015.
