Non-invasive Measuring of Cerebral Perfusion After Severe Brain Injury With Near-infrared-spectroscopy and ICG

April 17, 2013 updated by: Gerrit Brinker, University of Cologne

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

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame

Time Frame: 15 days after ictus
15 days after ictus

Secondary Outcome Measures

Outcome Measure
Time Frame
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
15 days after ictus and follow up 6 month later
