献全血者可发生慢性缺铁,血清铁蛋白降低。月经期女性铁消耗比男性和非月经女性明显。以前的研究表明,铁蛋白水平和献血频率有关。铁消耗可以通过适量的口服铁剂来预防。而长期献血的人是否需要补充铁则意见不一。普遍接受的看法是,Hb水平低于临界值时就不能献血,因为有缺铁性贫血的可能。铁缺乏的危险性可以通过限制全血献血员的献血频率来减低,可定为每8周献血1次。 作者还不知道频繁地单采血浆对于铁贮备的影响。在美国和一些欧洲国家实施的单采血浆可能伴随有大量的红细胞丢失,这些红细胞丢失在体外一次性用的塑料袋里,另外还要加上 Chronic iron deficiency can occur in patients with whole blood, serum ferritin decreased. Female iron consumption during menstruation than men and non-menstrual women significantly. Previous studies have shown that ferritin levels and frequency of blood donation. Iron consumption can be prevented with the right amount of oral iron. The long-term blood donors need iron supplementation is mixed. It is generally accepted that blood donations can not be made at Hb levels below the threshold because of the possibility of iron deficiency anemia. The risk of iron deficiency can be reduced by limiting the frequency of blood donations from whole blood donors, which can be given once every 8 weeks. The authors do not yet know the impact of frequent apheresis on iron stores. Apheresis plasma administered in the United States and some European countries may be accompanied by a significant loss of red blood cells that are lost in disposable plastic bags in vitro and additionally
