Evaluation of the Corrected Carotid Flow Time and the Inferior Vena Cava Collapsibility Index in Predicting Post-spinal Anesthesia Hypotension in Geriatric Patients

Corrected carotid flow time correction: is the carotid systole time, with heart rate correction applied IVC Collapsibility Index measurement is a reliable predictor of intraoperative hypotension within 30 minutes of spinal anesthetic administration
