光疗对新生儿血清钙影响

目的探讨蓝光治疗新生儿高胆红素血症对血清钙的影响。方法将90例新生儿高胆红素血症患儿按胎龄分为足月儿及早产儿两组,足月儿50例,早产儿40例,测定光疗前后血清钙水平,比较两组低钙血症的发生率。结果足月儿和早产儿光疗后血清总钙和游离钙均下降（P〈0.01）,早产儿低钙血症的发生率为50.0%,足月儿为28.0%,两组比较有显著性差异（P〈0.05）。结论新生儿接受光疗时易发生低钙血症,其中早产儿比足月儿发生率更高,光疗时应监测血钙浓度,必要时补钙。

Effection of phototherapy on Serum Calcium in Neonates

Objective To study the effect of phototherapy on cerum calcium in Neonates with hyperbil- irubinemia. Methods 90infants with hyperbilirubinemia were divided into two groups by gravidity time ： preterm group and term group. Serum calcium was measured before and after phototherapy. The incidence of hypocalcemia was compared between the two groups. Results Total serum calcium concentration decreased after phototherapy in both groups. The incidence of hypocalcemia in preterm infants were 50. 0%, significantly higher than that of term infants, which were 28.0% （ P 〈 0. 05 ）. Conclusion Neonates would get hypocalcemia while they are undergoing phototherapy. Preterm infants would be easier get that than term infants during the cause. The concentration of serum calcium should be test during the phototherapy, and the neonates should be supplied calcium sometime.
