摘要：

Erythrocyte sodium and potassium were studied in 64 newborn infants including 21 very low birthweight infants (birthweight < 1500 g) during the first three days after birth. Erythrocyte sodium showed a positive correlation with gestational age (r = 0.63, p < 0.01) and birthweight (r = 0.66, p < 0.01). Erythrocyte potassium was negatively correlated with birthweight (r = -0.33, p < 0.05). The Na/K ratio in red blood cells showed a positive correlation with gestational age (r = 0.60, p < 0.01) and birthweight (r = 0.65, p < 0.01). In VLBW infants plasma potassium rose significantly (p < 0.01) from 0-6 h to 12-30 h and decreased from 12-30 h to 30-60 h (p < 0.05). Erythrocyte potassium decreased slightly from 0-6 h to 12-30 h, but not significantly. A new finding that "more immature infants have higher potassium and lower sodium concentration in RBC" may suggest a potential risk of hyperkalaemia in tiny infants.
