Intervention
Control
Patients assigned to the study group will receive Ang 2 infusion in addition to standard vasopressor regimen. Ang 2 is currently approved at UCLA as a second line vasopressor and will be used as such for the purposes of our study. Hemodynamic goals will be established at the beginning of the case by the anesthesiology and surgical teams. Ang 2 will be started as a second vasopressor once the norepinephrine dose has reached 0.05mcg/kg/min. Ang 2 will be initiated at a starting dose of 5ng/kg/min. That dose will be up titrated one time to 10ng/kg/min as vasopressor requirements escalate. Once a patient is on the 10ng/kg/min dose of ang 2, no additional up titration will be performed. Hemodynamic management will continue throughout the case with titration of other vasopressors as needed. Ang 2 will be continued throughout the intraoperative period but will be weaned off prior to leaving the operating room.
Patients assigned to the control group will undergo intraoperative management with a standard vasopressor regimen composed of norepinephrine, vasopressin and epinephrine based on hemodynamic goals established by the surgical and anesthesia teams prior to surgery.
