Ultrasound-Guided Resuscitation in Open Aortic Surgery

This study will aim to determine whether routine Point of Care Ultrasound (POCUS) assessment of volume status, cardiac function, and pulmonary function after major abdominal aortic surgery is an accurate and feasible form of monitoring for individualized, goal-directed resuscitation. Half of the patients will receive POCUS-guided fluid resuscitation, and the other half will be resuscitated using usual post-operative care.
