The purpose of this study is to show if it is possible to detect secondary ischemic events in patients with severe brain injury or cerebral haemorrhage with the help of non-invasive near-infrared spectroscopy (NIRS) by using the indocyanine green measuring of cerebral perfusion.

Condition Intervention
Subarachnoid Hemorrhage, Aneurysmal
Intracerebral Hemorrhage (ICH)
Traumatic Brain Injury
Procedure: measuring cerebral perfusion by NIRS with ICG

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Continuous, Non-invasive Monitoring of Cerebral Oxygenation and Perfusion Using Near-infrared Spectroscopy With Indocyanine Green Perfusion Measurement in Patients With Traumatic Brain Injury, Intracerebral or Subarachnoid Hemorrhage

Primary Outcome Measures:
  • with near-infrared-spectroscopy detected cerebral perfusion deficit [ Time Frame: 15 days after ictus ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determining a threshold value for cerebral autoregulation measured with near-infrared-spectroscopy as a predictive value for the clinical outcome [ Time Frame: 15 days after ictus and follow up 6 month later ] [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: June 2013
Estimated Study Completion Date: June 2016
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: indocyanine green
in this arm we do the Intervention 'measuring cerebral perfusion by NIRS with ICG', the pat. gets before a CT-Scan with perfusion measurement a indocyanine green bolus i.v. and a measurement of cerebral perfusion with near-infrared-spectroscopy
Procedure: measuring cerebral perfusion by NIRS with ICG
application of a bolus of 5mg indocyanine green (ICG) in 3ml saline 0,9% i.v. in 1 second and measuring the ICG turnover with the near-infrared-spectroscopy (NIRS)
Other Names:
  • indocyanine green
  • NIRO-200NX C10488, Hamamatsu Photonics K.K.
