Acustocerebrography (ACG) in Severe Brain Injury — ACG-BrainICU  

Brain Injuries, Acute Clinical Trial

Official title: Study on Additive Use of Non-invasive Acustocerebrography in Patients Suspect to Severe Brain Injury

Status Recruiting

Clinical Trial Summary

The study will enable the clinical applicability of the multiple-spectral-sonography for detection of severe brain injury in ICU patients. For this, the ACG diagnostic system (Sonovum AG, Leipzig, Germany) should be used as additional diagnostic tool in prospective single-center study.

Clinical Trial Description

A multiple-step procedure, including repetition of the clinical examinations after a waiting period and use of additional technical diagnostic tools e.g. magnetic resonance tomography and Transcranial Doppler sonography (TCD) are needed for determining of severe brain injury and irreversible brain function failure.

This study will enable the clinical applicability of the multiple-spectral-sonography for detection of severe brain injury in ICU patients. For this, the ACG diagnostic system (Sonovum AG, Leipzig, Germany) should be used as additional diagnostic tool in prospective single-center study.

The ACG-method is a bedside non-invasive sonography that has been shown to be useful in previous studies analyzing circulatory changes in rat cerebral blood vessels, for example, to distinguish between brain-ischemia and -hemorrhage. Additionally, in the case of brain death, the spontaneous electrical activity, which can be measured by means of ACG as global elasticity, was not longer detectable.

In the study should include 30 adult ICU-patients in patients suspect to severe brain injury. The inclusion of patients will be started if written informed consent was obtained from participants or their representatives. After the inclusion, the ACG is measured three times a day. In addition, the routinely practice (treatment and diagnostic) for patients with severe brain injury (neurological clinical examinations, use of additional technical diagnostic tools e.g. magnetic resonance tomography and Transcranial Doppler sonography (TCD); Standard Medical Care) should be made and documented. From all patients basic demographic data, pre-morbidity, vital parameters, blood parameters, Illness severity scores (APACHE-II, SOFA, GCS), drug levels, microbiological results and cranial MRI/CT results will be recorded. ;
