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: None (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

Further study details as provided by Gerrit Brinker, University of Cologne:

Primary Outcome Measures:
  • with near-infrared-spectroscopy detected cerebral perfusion deficit [ Time Frame: 15 days after ictus ]

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 ]

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.


Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)

Inclusion Criteria:

  • Patients over 18 years
  • onset of clinical symptoms of subarachnoid or intracranial haemorrhage or trauma suffered less than 72h

  • A signed informed consent by the patient or legal guardian

Exclusion Criteria:

  • Persistent epidural, subdural or subcutaneous hematoma in planned area of the NIRS optode
