What this trial studies

This study examines the relationship between the early administration of L-Arginine following cardiopulmonary bypass (CPB) during cardiac surgery and the occurrence of acute kidney injury (AKI) in adult patients. It aims to determine if L-Arginine can effectively reduce the incidence of post-operative AKI. The study is observational and focuses on patients who have undergone CPB-assisted cardiac surgery and are admitted to the ICU for recovery.

Who should consider this trial

Good fit: Ideal candidates are adult patients over 18 years old who have undergone CPB-assisted cardiac surgery and are admitted to the ICU.

Not a fit: Patients with congenital heart disease, those who underwent deep hypothermic circulatory arrest, or those with a glomerular filtration rate below 30 mL/min/1.73 m² may not benefit from this study.

Why it matters

Potential benefit: If successful, this could lead to improved kidney health and recovery outcomes for patients undergoing cardiac surgery.

How similar studies have performed: There is limited information on similar studies, making this approach relatively novel in the context of post-operative AKI management.
