Abstract

Hyperkalemia is a frequent electrolyte imbalance in very preterm infants, often occurring in the first 72 hours of life. A unique entity, non-oliguric hyperkalemia (NOHK), is characterized by elevated serum potassium despite adequate urine output. While frequently reported, its risk factors, biochemical profile, and outcomes remain inadequately understood, particularly in low- and middle-income countries. To determine the incidence, maternal and neonatal risk factors, biochemical profile, and outcomes associated with NOHK in preterm neonates born
