Prediction of Hypotension During Induction of General Anesthesia

August 2, 2024 updated by: Ain Shams University

Assessment of Ultrasonographic Carotid Artery Corrected Flow Time and Internal Jugular Vein Collapsibility Index in Prediction of Hypotension During Induction of General Anesthesia

Post induction hypotension is closely related to postoperative complications. Patients are at high risk of hypotension due to preexisting hypovolemia and the vasodilatory effects of induction agents. Ultrasonographic measurement of the Carotid artery corrected flow time and internal jugular vein collapsibility index may predict post induction hypotension.
