摘　　要：用自动K、Na、Ca离子分析仪对生后1～5天的88例正常新生儿及42例窒息儿进行了血浆游离钙测定。结果发现正常新生儿组1～5天内血浆游离钙呈一动态变化。第三天最低,以后逐渐升高至正常。窒息组血浆游离钙降低,原因可能是缺氧使钙离子从细胞外转入细胞内。血浆游离钙受pH影响,在测定游离钙时应同时测血pH。The serum ionized calcium of 88 normal Neonates aged 1-5 days and 43 asphyxiated were determined. The results showed that the levels of ionized calcium of normal newborns falled at 1-3 days after birth, then increased and stabilized. Low levels ionized calcium were detected in 42 babies who suffered from birth asphyxia. The possible causes of these changes and the relationship between acidosis and hypocalcemia were discussed.
