[Can EEG monitoring with the Trend Analyzer replace stump pressure measurement in carotid surgery?].
Description of the EEG-trend-analyzer as an intraoperative monitoring during carotis surgery. Criteria for the evaluation of the findings are presented. In a prospective study 92 patients underwent monitoring with the EEG-trend-analyzer as well as the measuring of the internal carotid artery stump pressure. EEG monitoring shows a sensitivity of 100% for ischemic events, compared to 67% for the stump pressure measurement with a threshold of 50 mm Hg. EEG monitoring shows false positive results in 25% but no false negative results. Stump pressure investigation of the internal carotid artery is a very unreliable parameter for cerebral ischemia and inferior to the results of EEG-monitoring.
