Amino Acid Infusion in Cardiac Surgery

The goal of this study is to see if an infusion of amino acids given to adult male and female patients during cardiac surgery can help prevent acute kidney injury that commonly occurs when patients undergo cardiac surgery needing cardiopulmonary bypass. The main question the study aims to answer is if a short infusion of amino acids given to study participants during their scheduled heart surgery can decrease rates of acute kidney injury - which will be measured by biological markers of kidney injury in the urine. The study will be conducted in 2 phases. Participants in the first phase will receive the current standard of anesthetic care for patients having heart surgery and markers of acute kidney injury will be measured before and after their surgery. Participants in the second group will receive the anesthetic standard of care plus a short infusion of amino acids during their surgery. They will also have markers of kidney injury measured before and after their surgery. This study is based on prior studies that showed amino acid infusions are protective against kidney injury; however, these past studies did not look at markers of kidney injury in the urine.
