Considerations after intraoperative monitoring of somatosensory evoked potentials during carotid endarterectomy.
Somatosensory evoked potentials (SEPs) following median nerve stimulation were used to monitor cerebral function during 26 carotid endarterectomies. The patients with minor SEP variations had no neurological deficits on regaining consciousness while the one with more serious SEP variations had a transient deficit. The method thus seems useful in the early detection of ischemic brain impairment.
