EXPRESS: Preoperative Corrected Carotid Flow Time Is Associated With Spinal Anesthesia-Induced Hypotension in Hypertensive Patients: A Prospective Observational Study.
BACKGROUND Spinal anesthesia-induced hypotension (SAIH) is common in hypertensive patients, yet reliable preoperative markers remain limited. Corrected carotid flow time (CCFT) is a Doppler-derived index influenced by preload and ventricular ejection timing, but its association with SAIH in this population has not been...
