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。
Objective To investigate the effect of blue light on neonatal hyperbilirubinemia on serum calcium. Methods 90 cases of neonatal hyperbilirubinemia were divided into full-term infants and premature infants by gestational age, 50 cases of full-term infants and 40 cases of preterm infants, serum calcium levels were measured before and after phototherapy, compared with two groups of low-calcium The incidence of blood disease. Results The total serum calcium and free calcium in term infants and premature infants after phototherapy decreased (P <0.01). The incidence of hypocalcemia in preterm infants was 50.0% and that in term infants was 28.0%. There was a significant difference between the two groups (P <0.05). Conclusions Neonates are susceptible to hypocalcemia when receiving phototherapy. Among them, the incidence of preterm infants is higher than that of term infants. Calcium concentration should be monitored during phototherapy and calcium supplementation should be taken if necessary.
