目的:了解妊娠妇女体内无机元素的含量水平,指导孕妇合理的补充缺乏元素。方法:对来医院做产前检查的527例孕妇无名指尖采血,用BH-5100智能型火焰原子吸收光谱仪及配套试剂,采用一次进样检测血中五种无机元素的含量并与其他成人比对。结果:孕妇血中铁、锌平均含量分别为451.72μg/mL、7.32μg/mL,与其他成人平均含量比较无明显差别(P>0.05),而铜、钙、镁平均含量分别为0.83μg/mL、70.94μg/mL、38.46μg/mL,明显高于其他成人(P<0.01);孕妇锌、铜、钙元素低标/缺乏者分别为15.9%、4.7%、3.8%,锌、铁、钙、铜元素高标/过量者分别为19.0%、11.0%、1.5%、0.4%。结论:部分孕妇存在某种无机元素低标/缺乏或高标/过量的情况,其中以锌、铁异常的比例最高,孕妇补充微量和常量元素时,不可盲目进补,要依据机体的含量,在医生的指导下进行。
Objective: To understand the level of inorganic elements in pregnant women in vivo, to guide the lack of adequate supplementation of pregnant women elements. Methods: 527 pregnant women who came to the hospital for prenatal examination were taken anonymous finger-tip blood. The contents of five inorganic elements in blood were detected by BH-5100 intelligent flame atomic absorption spectrometer and matched reagents and compared with other adults . Results: The average levels of iron and zinc in pregnant women were 451.72μg / mL and 7.32μg / mL, respectively, with no significant difference compared with other adults (P> 0.05), while the average contents of copper, calcium and magnesium were 0.83μg / mL , 70.94μg / mL and 38.46μg / mL respectively, which were significantly higher than those in other adults (P <0.01). The pregnant women with low subscript / deficiency of zinc, copper and calcium were 15.9%, 4.7% and 3.8% , Copper superscript / excess were 19.0%, 11.0%, 1.5%, 0.4%. Conclusion: Some pregnant women have some low or high standard / excess inorganic elements, of which the highest proportion of zinc and iron abnormalities, pregnant women supplementation of trace elements and elements can not blindly tonic, according to the body’s content in Under the guidance of a doctor.
