[摘要] 目的:探讨早产适于胎龄儿低钠血症的早期预防。方法:对151例早产适于胎龄儿(PAGA)血清Na+进行动态检测,将其随机分为三组:A组51例,B组54例,C组46例。A、B组分别于生后24、48 h开始静脉泵注Na+ 2～3 mmol/kg,C组生后72 h内不补Na+。生后即时及生后满72 h,查血清Na+。结果:生后即时血清Na+均在130～150 mmol/L。72 h后,血清Na+<130 mmol/L者,A组4例,B组19例,C组27例,低钠血症发生率,三组之间两两比较,差异具有统计学意义(P<0.001),无一例血清Na+>150 mmol/L。结论:早期预防,可降低早产适于胎龄儿低钠血症的发生率,且无导致高钠血症的危险性。

[Abstract] Objective: To discuss the early prevention of hyponatremia in premature infants appropriate for gestational age. Methods: Dynamic testing of serum Na+ on 151 cases of preterm infant appropriate for gestational age (PAGA). They were randomly divided into three groups, A group of 51 cases, B group of 54 cases and C group 46 cases. A and B groups were started intravenous infusion of Na+ for 2-3 mmol/kg at 24 hours、 48 hours after birth, respectively. C group didn′t supply Na+ within 72 hours after birth. Serum Na+ were tested immediately after birth and at 72 hours after birth. Results: Serum Na+ were at 130-150mmol/L immediately after birth. After 72 hours of serum Na+ <130mmol/L, were A group 4 cases, B group 19 cases and C group 27 cases. Compare the incidence of Hyponatremiaof the three groups, there was a highly significant difference(P<0.001).No case of serum Na+>150 mmol/L. Conclusion: Early prevention can reduce the incidence of Hyponatremia in premature infants appropriate for gestational age,and there is no risk for hypernatremia.

低钠血症是早产适于胎龄儿(premature appro-priate for gestaional age,PAGA)常见严重并发症,是导致PAGA中枢神经系统永久性损害,甚至死亡的原因之一[1-2]。如何预防PAGA低钠血症,却少见报道。2005年4月～2009年3月,笔者对本院分娩的151例PAGA血清Na+进行了前瞻性研究,旨在探讨PAGA低钠血症的早期预防。现报道如下:
