Abstract
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.
Sommario
I Potenziali Evocati Somatosensoriali (PES) da stimolazione del nervo mediano sono stati usati come metodo per monitorare la funzione cerebrale durante endoarteriectomia carotidea.
Sono stati eseguiti 26 interventi di endoarteriectomia carotidea in 23 pazienti. Durante il clampaggio carotideo, più frequentemente si è osservato un aumento della latenza della P25, che in nessun caso è risultato superiore ai 2 msec.
In un solo paziente si è registrato un appiattimento monolaterale della traccia con scomparsa delle componenti N20 e P25; tale paziente era l'unico a presentare un deficit neurologico al risveglio. I nostri dati sembrano suggerire l'utilità del monitoraggio intraoperatorio del PES del mediano, al fine di svelare una sofferenza ischemica cerebrale.
