Medical technology company Medtronic has launched its neonatal acute dialysis machine in the US to treat paediatric patients who need renal replacement therapy.

The Carpediem Cardio-Renal Pediatric Dialysis Emergency Machine has been designed to be used in acute kidney injury or fluid overloaded patients who require hemodialysis or hemofiltration therapy.

Patients, weighing between 2.5kg and 10kg, can receive continuous renal replacement therapy (CRRT) with the machine.

Earlier this year, the machine received the US Food and Drug Administration’s (FDA) marketing authorisation.

In addition, in the US, the first Carpediem systems were installed and are currently in use at Cincinnati Children’s Hospital Medical Center.

Cincinnati Children’s Hospital Medical Center, Center for Acute Care Nephrology director and paediatrics professor Stuart Goldstein said: “CRRT procedures performed for critically ill infants using previously available technology are not optimal largely because dialysis machines available in the US are not designed to treat these small, fragile patients and can potentially expose them to many risks.

“This new system is designed specifically for these patients, which enables increased precision of neonatal CRRT treatment and, potentially, reduces these risks.”

CRRT is given to critically ill patients whose kidneys do not function properly.

In this therapy, a hemofilter will be used to pump the patient’s blood for the removal of waste and excess fluid while reducing the risk of hypotension and cardiac stability.

Estimates show that the mortality rate for neonates with acute kidney injury is at 60%.

Generally, paediatric patients who require CRRT are treated with systems designed and indicated for adults.

These systems are not approved for use in paediatric patients and can cause clinical complications in neonates.

The Carpediem system addresses such issues.
