Nerve conduction parameters during ischemia-reperfusion in the rat sciatic nerve

Abstract

We investigated the duration of electrophysiological alterations in the rat sciatic nerves during ischemia-reperfusion. Motor nerve conduction velocities were lower than the control group in 1- and 2-hour ischaemia groups after one day while there was no reading for the 3-hour ischaemia group till the seventh day, which was lower than control group. In the 1-hour ischaemia group, all parameters returned to normal on the seventh day but motor nerve conduction velocity decreased again on the 14th day and then returned to a normal level once again on the 21st day. All parameters were found to return to normal levels in the 2-hour ischaemia group on the 30th day and the 3-hour ischaemia group on the 60th day.
