摘要 目的 评价不同剂量的重组人类促红细胞生成素(rHuEPO)防治早产儿贫血的效果,寻找最佳剂量。方法 将152例胎龄〈35周,体重〈2.5奴的早产儿随机分为大剂量组、中剂量组、小剂量组和对照组,分别于生后7d接受rHuEPO治疗,剂量分别为每周750、450、150U/kg,分3次给予皮下注射,共4周。各组均于第3周开始口服铁剂2~8/mg(kg·d)。观察各组早产儿血红蛋白(Hb),红细胞压积(HCT),网积红细胞,血清铁的动态变化。结果 各组早产儿lib、HCT均逐渐下降,但对照组下降明显大于其他各组,P〈0.01,大剂量组下降幅度最小。对照组网积红细胞逐渐下降。各治疗组于第2周末逐渐上升,尤以大剂量组为明显,P〈0.05。对照组有9例输血,小剂量组有4例输血,其他各组无输血,差异有显著性,P〈0.01。各组血清铁生后均呈下降趋势,但治疗期间对照组下降较其他各组慢,P〈0.05。结论 rHuEPO能防治早产儿贫血。且大剂量较小剂量效果好。
