Comparison of the Application in Traumatic Brain Edema Between EIT and Non-invasive ICP Monitoring

Comparison of the Application in Traumatic Brain Edema Between Electrical Impedance Tomography and Non-invasive Intracranial Pressure Monitoring

Brain edema is the main reason for the disability and lethality in traumatic brain injury, which is the most difficult part of emergency rescue. Recently, there is no medical equipment to monitor the early brain edema in clinic. We have found that Electrical impedance tomography (EIT) can perform the real-time and bedside monitoring of brain electrical impedance after single-dose mannitol treatment, which may be a new strategy for the surveillance of brain edema. In this study, we would like to compare the application in traumatic brain edema between EIT and Noninvasive intracranial pressure (ICP) monitoring, including the progress of brain edema, the relationship between impedance and ICP, and the improvement for the patients' prognosis. EIT would probably be a new image strategy for the treatment of traumatic brain injury.

3. All the patients had provided written informed consent.

6. The patients were receiving usual inpatient rehabilitation and conservative treatment .

Exclusion Criteria:

1. The patients with indication of operation during the research should be excluded.
2. The patients were assessed as unqualified for the study according to the comprehensive evaluation opinion brought forward by the research team.
