Hyperkalemia: The Trojan horse of pediatric transfusion?

Preventing transfusion-associated hyperkalemia in pediatric cardiac surgery: Measure the levels of potassium in packed red blood cells before using - Invited commentary

The authors present a revolutionary study aiming to evaluate the effect of alterations in potassium concentrations in transfused packed red blood cells (PRBC) on the neonate and infant potassium levels after congenital cardiac surgery. By establishing a strict protocol that restricts the rate of transfusion, the age of the transfused PRBC, and not transfusing a PRBC with a potassium level above 15 mmol/L, they accomplished to suggest a safe and easy way for preventing transfusion-associated hyperkalemia.
