Interventions for non-oliguric hyperkalaemia in preterm neonates.

Non-oliguric hyperkalaemia of the newborn is defined as a plasma potassium level > 6.5 mmol/L in the absence of acute renal failure. Hyperkalaemia is a common complication in the first 48 hours of life in very low birth weight (birth weight < 1500 g) and/or very preterm newborns (< 32 weeks gestational age).
