摘要
测定23例足月危重新生儿危重期及恢复期双份血样中与钙代谢有关的生化指标，结果显示危重期血总钙、游离钙、镁、甲状旁眼激素及红细胞膜钙系活性低于对照组及恢复期（P＜0．01），而血磷、降钙素、红细胞总钙浓度高于对照组及恢复期（P＜0．01），恢复期与对照组各指标差异无显著性（P＞0．05）。说明危重新生儿常伴有低钙血症，其原因为甲状旁腺受损功能低下、降钙素分泌增多、钙系活性下降钙内流及低血镁、高血磷等。治疗上应首选钙通道阻滞剂而非盲目补钙，还应重视血镁的测定及补充。
The levels of plasma total calcium (BCat), ionized calcium (BCai), phosphrous (Pi),magnesium (Mg), parathormone (PTH) and calcitonin(CT), and the concentration of erythrocyte calcium (Ery Cat) and the activity of erythrocyte membrane Ca-pump (Ca-pump)were measured in 23 critically ill newborns in their crisis stage and convalescent stage. The results showed that in crisis stage the levels of BCat, BCai, Mg, PTH and the activity of Capump were significently decreased, wheres the concentrations of plasma Pi, CT and Ery Cat were obviously increased than that in control group and convalescent stage. The difference of all indications from contral group and convales cent stage was not remarkable.
