What this Trial Is About

Researchers are evaluating the use of a furosemide stress test (FST) to help determine kidney recovery in critically ill patients with acute kidney injury (AKI) who are undergoing continuous renal replacement therapy (CRRT). This study aims to address the lack of evidence on the best timing to stop CRRT, as prolonged CRRT can lead to complications like infections, low blood pressure, and heart rhythm issues. The study is a randomized controlled trial sponsored by Chiang Mai University.
