Abstract

Objective: The aim of this study is to evaluate the usefulness of a spectral function detecting cerebral hypoperfusion. Methods: Continuous electroencephalographic monitoring was employed during 47 consecutive carotid endarterectomies. Patients were assigned to 3 different groups according to the entity of electroencephalographic changes during carotid clamping (major changes: group A; moderate changes: group B; no change: group C). The desynchronization function, indicating the reduction of the 8-15 Hz band power, and the desynchronization index were calculated. Results: Group A function decreased within 20 s from clamping, with a constant slope (7.14). Desynchronization indexes were: 76.85% (group A), 40.23% (group B) and 15.29% (group C). Difference among groups was statistically significant (P
