Cost-effectiveness Analyses for the Prevention of Acute Kidney Injury in Patients Undergoing Cardiac Surgery in the UK

The RenalGuard Therapy® is comprised of a console, a single-use sterile IV infusion set, urine collection set and a cart. The console is a microcontroller device that has a means for measuring urine output and automatically controls the hydration infusion pump based on the measured urine output and clinician settings. The system is designed for infusion of hydration solutions only. The patient is connected to the console by the IV Infusion set connected to the patient's peripheral IV cannula and the urine collection set connected to the patient's indwelling Foley urinary catheter. The console continuously monitors urine production by measuring the weight of urine in the collection set, converts the urine weight to volume and then, automatically infuses the pre-set volume of hydration fluid to compensate for this output.
