RT Journal Article SR Electronic T1 Early hyperkalaemia in very low birthweight infants in the absence of oliguria. JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 270 OP 272 DO 10.1136/adc.64.2.270 VO 64 IS 2 A1 L P Brion A1 G J Schwartz A1 D Campbell A1 A R Fleischman YR 1989 UL http://adc.bmj.com/content/64/2/270.abstract AB We reviewed 1552 admissions to a neonatal intensive care programme; seven, all with a birth weight less than 1500 g, developed early onset, non-oliguric hyperkalaemia (potassium concentration greater than 7.0 mmol/l). Although their perinatal variables were similar to those of a normokalaemic group, hyperkalaemic infants had a higher incidence of intraventricular haemorrhage and developed increased concentrations of plasma creatinine by 7 days of age.
