Abstract:
PURPOSE: The aim of this study is to evaluate the incidence of hyperkalemia and the contributing factors of nonoliguric hyperkalemia in low birth weight infants within 48 hours after birth. METHODS: The incidence of nonoliguric hyperkalemia and difference of clinical features between hyperkalemia (>6.7 mEq/L) and normokalemia (< or =6.7 mEq/L) groups were determined by reviewing medical records of 196 low birth weight infants who were born in Hanyang university hospital between Oct. 2001. and Jul. 2004. We analized the serum level of sodium, potassium, fluid intake, urine output, pH of blood gas and others. RESULTS: Among 196 infants, 17 infants was hyperkalemia developed in 48 hours after birth. In that cases, 10 infants were showed EKG abnormalities, such as ventricular tachycardia. In all cases, birth weight, gestational age, Apgar score, usage of surfactant, urine output, BUN and creatinine were significant. In A group gestational age, urine output, BUN, creatinin were significant, in B group BUN, creatinine were significant, in C group BUN were significant between hyperkalemia and normokalemia. Six infants with hyperkalemia died as a result of hyperkalemia induced cardiac arrhythmia. CONCLUSION: Hyperkalemia frequently occurred extremely premature infants. But hyperkalemia also be developed in low birth weight infants who were not suffered from asphyxia or tissue damage. Serum potassium level should be monitored to avoid life threatening cardiac arrhythmia in low birth weight infant.
