早产儿贫血是指早产儿(胎龄满28周至不满37足周)生后1年内发生的贫血。目前国内多以生后2周内静脉血血红蛋白(hemoglobin,Hb)<135 g/L或末梢血Hb≤145 g/L[1]、2周~1个月末梢血Hb≤110 g/L、>1个月~4个月末梢血Hb<90 g/L、>4个月~6个月末梢血Hb<100 g/L、6个月以后末梢血Hb<110 g/L为诊断标准[2]。贫血可影响婴幼儿的生长发育,引起心、脑、免疫等其他系统器官损害,严重时甚至可危及患儿生命。随着医疗技术的进步,早产儿抢救成功率及存活率明显提
Anemia in premature infants refers to anemia that occurs in preterm infants (gestational age from 28 weeks to less than 37 weeks) within 1 year of birth. At present, hemoglobin (Hb) is less than 135g / L or peripheral blood Hb is less than 145g / L within 2 weeks after birth. Hb≤110g / L for peripheral blood from 2 weeks to 1 month, > 1 month to 4 months of peripheral blood Hb <90 g / L,> 4 months to 6 months of peripheral blood Hb <100 g / L, 6 months after the peripheral blood Hb <110 g / L for the diagnostic criteria [ 2]. Anemia can affect the growth of infants and young children, causing heart, brain, immune system and other organ damage, even in serious cases can endanger the lives of children. With the progress of medical technology, the success rate of rescue and survival of premature children was significantly raised
