目的:了解红细胞系各参数均值变化,为婴儿期贫血诊断及鉴别诊断提供依据。方法:对146例1岁以内婴儿的血常规进行检测。按血红蛋白Hb<90g/L、90≤Hb<100g/L、100≤Hb<110g/L、Hb≥110g/L分成四组。结果:婴儿期贫血发生率呈增加的趋势。随月龄增长,红细胞数逐渐增加,红细胞体积减小。3月时,当Hb<90g/L,多伴有MCV、MCH、MCHC的降低。8月时,Hb<110g/L以下时,也伴有RBC、HCT、MCV、MCH、MCHC的降低。从本文红细胞形态改变看,婴儿期贫血多数为小细胞低色素性的趋势,即营养性缺铁性贫血。结论:掌握婴儿期红细胞系的变化规律,定期检测血常规,适时给予干预及治疗,使婴儿期贫血得到有效监控。
OBJECTIVE: To understand the mean change of erythrocyte parameters and to provide basis for the diagnosis and differential diagnosis of anemia in infancy. Methods: 146 infants under 1 year old were tested for blood routine. Hemoglobin Hb <90g / L, 90≤Hb <100g / L, 100≤Hb <110g / L, Hb≥110g / L were divided into four groups. Results: The incidence of infant anemia showed an increasing trend. With the increase of age, the number of erythrocytes gradually increased and the volume of erythrocytes decreased. March, when Hb <90g / L, accompanied by more MCV, MCH, MCHC decreased. August, Hb <110g / L or less, but also accompanied by RBC, HCT, MCV, MCH, MCHC decreased. From the red blood cell morphology changes in this article, the majority of infantile anemia is the trend of small cell hypochromic, that is, nutritional iron deficiency anemia. Conclusion: To master the changes of erythrocytic line in infancy, regular blood tests, timely intervention and treatment, the baby anemia can be effectively monitored.
