Ketamine and Glutamate After Brain Injury : a Microdialysis Study

Summary

The objective of the study is to compare the effects of 48 hours ketamine infusion versus sufentanil infusion on brain glutamate concentrations measured with microdialysis after traumatic brain injury. We hypothesize that ketamine infusion will decrease high glutamate values faster than sufentanil.
