“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.

Diagnostic Test - Point of Care Ultrasound (POCUS)
The intervention group will receive a 4-view transthoracic echocardiogram including Parasternal long axis, parasternal short axis, apical 4-chamber, and supplemental subcostal short-axis/4-chamber views as needed. A standard 4-view thoracic lung ultrasound study will assess the left and right anterior chest wall, anterior axillary regions, as well as the costophrenic angle and posterolateral regions. At 5 discrete time intervals post-operatively, POCUS assessments will be used to adjust fluid re ...read more on ClinicalTrials.org
Usual Care
The control group for "usual care" will undergo resuscitation guided by modalities used currently, which can include both static and dynamic measures. These will include review of vital signs, biochemistry, and urine output as well as bedside physical exam. In this arm, patients will not undergo POCUS during their admission. IV fluid infusion rates as well as targets for IV boluses will be left to the discretion of the attending physician and can include hypotension, hypovolemia, as well as olig ...read more on ClinicalTrials.org
