Optimizing neuro-intensive care of traumatic brain injury

When employed in brain research, microdialysis is commonly used to measure neurotransmitters (e.g. dopamine, serotonin, norepinephrine, acetylcholine, glutamate, GABA) and their metabolites, as well as small neuromodulators (e.g. cAMP, cGMP, NO), amino acids (e.g. glycine, cysteine, tyrosine), and energy substrates (e.g.
glycine, cysteine, tyrosine), and energy substrates (e.g. glucose, lactate, pyruvate). Microdialysis can be performed in a specific brain region by inserting the microdialysis probe by stereotaxy into the area of interest in anesthetized or conscious animals. For the latter, it is necessary to place a cannula guide in the region of interest by stereotaxy first. Cerebral mikrodialys är en invasiv metod för att mäta den kemiska miljön lokalt i hjärnan.

Despite it's increasing popularity, the microdialysis technique is still far from being a routine method. 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.

dopamine, serotonin, norepinephrine, acetylcholine, glutamate, GABA) and their metabolites, as well as small neuromodulators (e.g. cAMP, cGMP, NO), amino acids (e.g. glycine, cysteine, tyrosine), and energy substrates (e.g. glucose, lactate, pyruvate). The microdialysis technique is an important tool in neurobiology and has provided much information on the complex functions of the intact brain.
The construction and geometry of the CMA 7 6 kDa Microdialysis Probe tip is exactly the same as in the CMA 11. Cerebral microdialysis is proving its worth as a clinical monitoring technique for severe brain injury, in which fundamental molecules, such as glucose, lactate and pyruvate, are measured at the bedside [74, 75], and is increasing its applicability to the study of drugs in the human brain as exemplified in the present review.
