Abstract:
Somatosensory evoked potentials(SEPs) reflect the functional integrity of the central neural pathways, and as such may be used to assess function that remains during variety of cerebral insults. To evaluate the utility of SEPs during cerebral ischemic deterioration due to aneurysmal subarachnoid hemorrhage, SEPs were measured in 43 patients with subarachnoid hemorrhage, among them 24 patients had no cerebral ischemic deterioration(group 1) and 19 patients had cerebral ischemic deterioration(group 2). In group 1, central conduction time(CCT) were measured on the day of admission(CCT1), the seventh day(CCT2), and the twenty-first day(CCT3) after aneurysmal rupture. In group 2, CCT were measured on the day of admission(CCT1), during(CCT2) and after resolution(CCT3) of cerebral ischemic deterioration. CCT2 of the both cerebral hemispheres were different significantly between two group(p=0.01). In group 2, there was stastically significantly difference between CCT1 and CCT2(p<0.01), and significant correlation between clinical grade and CCT was noted, especially in grade III, and IV. Therefore it is suggested that the central latencies of the SEPs are seemed to be a sensitive tools as indicators of the onset and extent of a cerebral ischemic deterioration due to aneurysmal subarachnoid hemorrhage.
