Continuous Somatosensory Evoked Potential Monitoring in the Neurointensive Care Unit
We describe a technique of continuous median nerve somatosensory evoked potential testing used as a monitoring device in our neurointensive care unit. Early experience suggests that such testing can be successfully done but demands a great deal of attention from technical and nursing personnel. Appropriate application of the technique may be in selected cases of therapeutic barbiturate anesthetic coma and in delayed ischemia from subarachnoid hemorrhage but in these and other potential situations clinical utility remains to be proven. The effects of commonly used drugs in the neurointensive care unit, such as lidocaine, as well as factors such as patient positioning, also need to be more completely evaluated.
