Study summary

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.
