目的探讨中重度贫血的缺铁性贫血患者的输血把握以及经单纯静脉补铁是否能在短期内快速改善贫血症状，观察其不良反应，以减少输血风险。方法将60例有输血指征的缺铁性贫血患者随机分两组：30例患者不输血单纯静脉补蔗糖铁为实验组，30例予输血2U后再予静脉补蔗糖铁为对照组，持续观察治疗4w，比较两组HGB提升差异以及不良反应发生情况。结果对照组在前3w HGB上升水平要高于试验组(0.05)。结论临床上遇到有输血指征的缺铁性贫血患者，当无明显活动性出血及生命体征稳定时，为避免输血风险及减轻血源紧张，可尝试单纯静脉补铁，亦可较短时间内纠正贫血。“,”Objective To study Severe anaemia in IDA blood transfusion grasp and investigate patients with iron deficiency anemia in moderate and severe anemia to cure simple intravenous iron whether can quickly improve symptoms of anemia in the short term,to observe the adverse reaction,in order to reduce the risk of blood transfusion.Methods 60 cases of transfusion indications in patients with iron deficiency anemiawere randomly divided into two groups:30 patients without blood transfusion of intravenous iron sucrose alone as the experimental group,30 cases treated with blood transfusion of 2U fol owed by intravenousiron sucrose as the control group,the observation lasted for 4 weeks,compared with two groups of HGB to enhance the dif erences and theadverse reactions occur ence the situation.Results 3 weeks before,the control group is higher than the experimental group in the rise of HGB level ( 0.05).Conclusion The clinical encounter with a blood transfusion indications in patients with iron deficiency anemia,when bleeding and vital signs were stable and no obvious activities,in order to avoid the risk of blood transfusion and reduce the blood source nervous,try simple intravenous iron supplement,also can be in a relatively short period of time to correct the anemia.
