Brain dysfunction following vasospasm evaluated by somatosensory evoked potentials

Summary

Somatosensory evoked potentials (SEP) were recorded in 9 patients with vasospasm caused by subarachnoid haemorrhage.

There was a correlation between SEP changes and clinical outcome evaluated one month after onset.

And, evaluation of SEP changes under induced hypertension or infusion of dehydrates was available to study the nature of ischaemic brain dysfunction caused by vasospasm.

Furthermore, this study suggests that the available period of induced hypertension may be short in cases with severe clinical outcomes.
