Introduction: Carotid endarterectomy (CEA) prevents stroke in patients with severe carotid stenosis. Near-infrared spectroscopy (NIRS) enables real-time monitoring of cerebral oxygen saturation, helping to reduce neurological complications. This study examines changes in oxygen saturation and their link to surgical outcomes.
Methods: This descriptive-analytical study was conducted on CEA patients at Razi Hospital, Rasht, Iran (2020–2021). Data included demographics, changes in cerebral oxygen saturation (rSO2) measured by INVOS®, and hemodynamic parameters. Descriptive and inferential statistical tests were used for analysis.
Results: Among 40 CEA patients studied, 72.5% were male, and 27.5% were female. Significant changes were observed in cerebral oxygen saturation (Channel 1: 65.93, Channel 2: 66.00, P < 0.05) and hemodynamic parameters. The trend of changes in mean blood pressure, including systolic blood pressure, diastolic blood pressure, and mean arterial pressure over time, was significant. (P <0.001). Early postoperative complications occurred in 37.5% of patients, with cardiac issues (32.5%) being the most common, followed by surgical site hematomas (5%). No surgical site infections were reported. Furthermore, analyses showed no significant relationship between changes in cerebral oxygen saturation (rSO2) or hemodynamic changes and the occurrence of postoperative complications.
Conclusion: Monitoring cerebral oxygen saturation using NIRS is recognized as a practical and effective tool for optimizing the management of carotid endarterectomy surgery. The findings underscore the importance of incorporating NIRS monitoring into standard surgical protocols to enhance clinical outcomes and potentially reduce the duration of hospital stays for patients.
