摘要
对74例新生儿进行了不同性质液体输入前后的全血游离钙（Ca2+）水平变化的观察。结果显示，按教科书规定的常规量及速度对新生儿输给新鲜血、血浆及人血白蛋白时，血Ca2+及pH值均无显著性变化。但输给碱性液体纠正酸中毒时，血Ca2+浓度则出现显著性下降现象。本研究提示，除换血和大量输血等特殊情况外，新生儿科的常规的输血及白蛋白的输入，一般不会引起血Ca2+水平的下降。鉴于补碱后患儿明显的血Ca2+水平降低，在临床上纠正酸中毒时，应严密观察血Ca2+变化。
The changes of blood inonized calcium before and after liquid transfusion were investigated in 74 neonates. The results indicated that no significant changes of blood ionized calcium were found before and after fresh blood, serum and human albumin transfusion. Blood lonized calcium concentrations decreased significantly after alkaline liquid transfusion. This study suggested that fresh blood, serum and human albumin transfusion, with the ordinary contents and speed, may not affect hlood ionized calcium concentration in neonates. As to the significant changes of blood ionized calcium during the alkaline liquid transfusion, blood ionized calcium should be detected closely in order to prevent neonatal tetany.
