ClinConnect Summary

This clinical trial is studying a tool called the renal resistive index (RRI) to see if it can help predict how acute kidney injury (AKI) progresses in patients being treated in intensive care. AKI is a serious condition where the kidneys suddenly start to work poorly, which can lead to complications. The researchers want to find out if measuring the RRI, a non-invasive test that looks at how well blood is flowing to the kidneys, can help doctors decide when patients might need further treatment, like dialysis.

To join the study, participants need to be over 18 years old and have been diagnosed with early stages of AKI within the first day of being admitted to the hospital. They should not have certain conditions, such as severe kidney problems or heart issues. If eligible, participants can expect to undergo the RRI test and be monitored closely during their hospital stay. This research is important because it could lead to better ways to identify and treat patients with AKI, ultimately improving their chances of recovery.
