Method and System for the Early Detection of Acute Kidney Injury

Case ID:
C13451
Acute kidney injury (AKI) is a condition where the kidneys become unable to adequately filter the blood, causing toxic levels of waste to accumulate throughout the body. AKI is formally defined as a “>50% decrease in glomerular filtration rate (GFR) over a period of hours to days,” which leads to a decline in urine output over time. Measuring urine output is one of the most acceptable forms of assessing a patient for AKI at present, and is an important component of the established RIFLE criteria that assess kidney function. AKI is a common event in cardiac surgery, with 5-30% of patients developing clinically significant acute kidney injury. The Renalert System is a portable urine monitor, which provides real-time and continuous feedback about urine output during cardiac surgery and in the intensive care unit. The Renalert monitor has the capability to be connected to the anesthesia monitor in order to track fluids and medications administered at different times and observe the patient’s physiological response.
