Abstract
The effects of spinal cord ischemia on spinal cord blood flow (SCBF) and somatosensory (SSEP) and motor (MEP) evoked potentials were investigated in a rabbit model of reversible spinal cord ischemia. Spinal cord ischemia was produced by balloon occlusion of the infrarenal aorta for 30, 60, and 90 min. SCBF, SSEPs, and MEPs were measured before, during, and 1 h after aortic occlusion. Aortic occlusion produced absolute ischemia of the caudal cord followed by hyperemia upon reperfusion. SSEP's and MEP's were obliterated during ischemia but demonstrated gradual albeit incomplete recovery following reperfusion with amplitude recovery inversely proportional to the duration of ischemia. Later peaks were more severely affected by a given period of ischemia than were early waves. In general, SSEP's were more resistant to ischemia than were MEP's although the differences were not significant. © 1993 Raven Press, Ltd., New York.
