Abstract
This report describes the acute hemodynamic effects of indigo carmine in a surgical patient with compromised cardiac function. A 68-year-old woman with stable but severe cardiac dysfunction and renal artery stenosis was scheduled for an elective aortorenal bypass procedure. No hemodynamic instability occurred during the operation until the patient was administered intravenous (IV) indigo carmine 5 ml. At that time, the patient experienced an acute increase in afterload, which resulted in acute left ventricular failure documented by a decrease in cardiac output (CO) and an increase in pulmonary artery pressure (PAP). Until further studies defining the mechanism for its hypertensive side effect are performed, indigo carmine should be used with caution in patients with severe cardiac dysfunction.
