1、静脉及口服铁剂对肾性贫血临床观察作者:张吉胜包蓿艳尤晓青刘婷刘苑萍吕敏【摘要】观察慢性肾功能不全患者静脉和口服补铁治疗肾性贫血的疗效、不良反应的发生情况以及对促红细胞生成素(EPO)使用效应的比较。[方法]将我院2006.11—2007.10期间病情稳定的48例肾性贫血患者随机的分为静脉组和口服组2组,每组24例,观察期10周。所有患者均常规使用EPO治疗,剂量为100U/kg・w,皮下注射,若患者血红蛋白(Hb)达10g/dl则将EPO剂量减少50%,若患者HB达12g/dl则将EPO剂量减少75%O观察
2、用药前、用药后4周、用药后8周、用药后10周的Hb、红细胞压积(Het).铁蛋白(SF)、不良反应以及应用EPO剂量。[结果]治疗后两组患者的Hb、Het、SF均较治疗前有明显升高,而静脉组升高幅度显著于口服组(PV0.01),两组患者应用EPO的剂量在治疗后较治疗前均有所减少,而静脉组减少明显(P<0.05),静脉组不良反应的发生率明显低于口服组,EPO的效应明显高于口服组。[结论]静脉补铁不仅能及时有效地补充肾性贫血患者所需的铁剂,使贫血状况改善,不良反应少,可安全应用,而且能增强EPO效应,减少其用量
