Anesthesia
Conditions
Brief 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.
Detailed description
* Type of Study: Observational Prospective Cohort Design. * Study Setting and ethical consideration: The approval of the Scientific Research Ethics Committee of the Faculty of Medicine, Ain Shams University will be obtained before starting work on the study. This study will be conducted in operating theatres of Ain Shams University Hospitals. Informed written consents to participate will be obtained from the patients. * Study Period: One year (October 2023-October 2024) * Study Population: Adult patient undergoing elective surgeries.
