Abstract
Cerebral microdialysis is an emerging monitoring technique that is currently being studied for treatment of neurologic diseases such as subarachnoid hemorrhage and traumatic brain injury. Its ability to sample the molecules of the extracellular environment gives real-time information on the changing brain tissue post injury. Looking at the trends and ratios of these molecules can help guide clinical intervention and possibly patient prognosis along with helping in the management of secondary injury. © 2018 Elsevier Inc.
