AI Article Synopsis
- CI-AKI is a common cause of acute kidney injury among hospitalized patients, particularly due to the use of contrast agents in medical procedures.
- Key risk factors for developing CI-AKI include old age, diabetes, heart failure, proteinuria, and low blood pressure.
- Hydration with crystalloids is the main prevention strategy, while other agents like NAC and hemodialysis are not effective or recommended for CI-AKI prevention.
Article Abstract
Contrast Induced Acute Kidney Injury (CI-AKI) is one of the most common causes of acute kidney injury in hospitalized patients. These days, contrast agents are widely being used in both cardiology and radiology procedures. Old age, history of diabetes, heart failure, proteinuria and low blood pressure are some important risk factors in the pathogenesis of CI-AKI. Apart from risk stratification and the use of low and iso-osmolar contrast agents, intravenous fluid hydration with crystalloids is the only recommended strategy for the prevention of CI-AKI. Agents like N-acetylcysteine (NAC), atrial natriuretic peptide, ascorbic acid, theophylline, and fenoldopam have failed to show any proven beneficial role in the prevention of CI-AKI. Though hemodialysis is still being perceived by many clinicians as the modality for contrast removal but prophylactic hemodialysis is now not recommended for the prevention of CI-AKI.
