Abstract
- Accumulation of potassium and excitatory amino acids (EAA) in the extracellular space (ECS) following ischemia has been well documented. Careful monitoring of these transients is crucial to gain a better understanding of CNS pathophysiology. This study was initiated to determine if CSF concentrations of EAAs reflect those measured in the ECS. Transient global ischemia, 20 minutes in duration, was produced by clamping the left subclavian and innominate arteries combined with hemorrhagic hypotension. The accumulation of glutamate and electrolytes were measured in CSF and the extracellular fluid (ECF) of cerebral cortex. Microdialysis (MD) was utilized to measure the extracellular concentrations while direct sampling of CSF was provided via cannulation of the cisterna magna. Hydrogen clearance and laser doppler methods were used to monitor regional cortical CBF.
