Carotid Doppler Parameters and Post-Induction Hypotension

Post-induction hypotension is a common complication following the induction of general anesthesia and is associated with adverse postoperative outcomes. Patients undergoing gynecologic oncology surgery represent a particularly vulnerable population due to advanced age, high comorbidity burden, and increased frailty, which may predispose them to perioperative hemodynamic instability. This prospective observational study aims to evaluate whether carotid Doppler ultrasonography parameters, including corrected flow time and other flow-related indices, can predict the occurrence of post-induction hypotension specifically in patients undergoing gynecologic oncology surgery. Adult patients scheduled for elective gynecologic oncology surgery under general anesthesia will undergo pre-induction carotid Doppler ultrasonography as part of routine perioperative assessment. Baseline clinical characteristics, including the Charlson Comorbidity Index and Clinical Frailty Scale, will be recorded for each participant. Hemodynamic parameters will be recorded following anesthetic induction, and the development of post-induction hypotension will be assessed. The findings of this study may help identify high-risk patients within the gynecologic oncology population and support the use of non-invasive carotid Doppler measurements, comorbidity burden, and frailty assessment for perioperative risk stratification in this specific surgical group.
