Microdialysis is a well established technique for chemical monitoring of brain tissue during neurointensive care. By introducing Microdialysis catheters into the brain after severe trauma or subarachnoid hemorrhage, it is possible to monitor brain tissue metabolism in the tissue at risk, i.e. the penumbra of a lesion or a region affected by vasospasm.

Microdialysis shall not be used as the sole basis for diagnosis or therapy.
