Brief Summary:
Previous studies did not reach a consensus on the influence of the type of anesthesiologic procedure and monitoring, during carotid thrombendarterectomy, on perioperative complications and cognitive outcomes. The aim of this study is the optimization of brain perfusion during the vascular carotid clamp using multimodal monitoring. We assume that standardized monitoring techniques and a better selection of cognitive tests will allow a more accurate assessment of subclinical cognitive deficits.
Detailed Description:
ABSTRACT:
AIM OF THE STUDY: Effect of perioperative multimodal monitoring with transcranial doppler (TCD), near-infrared spectroscopy (NIRS), and Electroencephalography (EEG) in patients for carotid thrombendarterectomy (CEA) on perioperative complications and cognitive functions.
PATIENTS AND METHODS: The prospective study will analyze 80 consecutive patients with an asymptomatic and symptomatic (transitory ischemic attack, TIA, in anamnesis) stenosis of the internal carotid artery in which CEA is indicated in general anesthesia. Cognitive tests will be analyzed for all patients preoperatively, first and eighth day postoperatively, and after 8 weeks. Breath-holding index (BHI) will be measured preoperatively and postoperatively. The first group of patients (n = 40) will have expanded intraoperative monitoring involving TCD, NIRS, and EEG, and the control group (n = 40) will have only standard anesthetic monitoring.
EXPECTED CONTRIBUTION OF THE STUDY: Previous studies did not agree on the influence of the type of anesthesiologic procedure and monitoring of perioperative complications and cognitive outcomes. We assume that standardized monitoring techniques and a better selection of cognitive tests will allow a more accurate assessment of the effect.
