妊娠期鐵（甘氨酸亞鐵Ferrous Glycinate、抗壞血酸亞鐵Ferrous L-Ascorbate）需求與缺鐵性盆血防治指南

鐵是人體必需的一種微量元素，是許多生理生化反應(yīng)不可或缺的，包括氧氣的運(yùn)輸和存儲(chǔ)，氧化磷酸化以及許多氧化還原反應(yīng)的催化。同時(shí)鐵也是造血的重要原料，孕期母體及胎兒對(duì)鐵的需求量增加，缺鐵性貧血是孕婦中最常見(jiàn)的貧血。為了滿足胎兒對(duì)于氧氣及營(yíng)養(yǎng)的需求，增強(qiáng)胎盤灌注，妊娠期母體血液粘度降低，血流速度增加，紅細(xì)胞體積增大。從懷孕的第六周開(kāi)始，血漿體積與紅細(xì)胞質(zhì)量不成比例地增加，在妊娠約 24 周時(shí)達(dá)到最大值，血漿量最大時(shí)比妊娠開(kāi)始時(shí)高40%-50%，會(huì)出現(xiàn)妊娠期生理學(xué)貧血。妊娠期間每天需要額外攝入約 1g 元素鐵（甘氨酸亞鐵Ferrous Glycinate、抗壞血酸亞鐵Ferrous L-Ascorbate）用于母體合成血紅蛋白、胎兒發(fā)育及在嬰兒早期建立鐵儲(chǔ)備。人們普遍認(rèn)為，在妊娠期間，孕婦缺鐵比鐵超負(fù)荷的風(fēng)險(xiǎn)更大。妊娠期鐵缺乏與缺鐵性貧血診治指南中指出，當(dāng)血清鐵蛋白<30ng/ml 是鐵耗盡的早期提示，需要盡早補(bǔ)充治療。

Iron requirements during pregnancy (Ferrous Glycinate, Ferrous L-Ascorbate) and iron-deficiency anemia prevention and treatment guide

Iron is an essential trace element for the human body and is indispensable for many physiological and biochemical reactions, including the transport and storage of oxygen, oxidative phosphorylation, and the catalysis of many redox reactions. At the same time, iron is also an important raw material for hematopoiesis. The demand for iron by the mother and fetus increases during pregnancy. Iron-deficiency anemia is the most common anemia in pregnant women. In order to meet the fetus's demand for oxygen and nutrition and enhance placental perfusion, the viscosity of the mother's blood decreases during pregnancy, the blood flow rate increases, and the volume of red blood cells increases. From the sixth week of pregnancy, the plasma volume increases disproportionately with the mass of red blood cells, reaching a maximum value at about 24 weeks of pregnancy. The maximum plasma volume is 40%-50% higher than at the beginning of pregnancy, and physiological anemia during pregnancy will occur. During pregnancy, an additional intake of about 1g of elemental iron (Ferrous Glycinate, Ferrous L-Ascorbate) is required every day for maternal hemoglobin synthesis, fetal development, and the establishment of iron reserves in early infancy. It is generally believed that during pregnancy, pregnant women are at greater risk of iron deficiency than iron overload. The guidelines for the diagnosis and treatment of iron deficiency and iron deficiency anemia during pregnancy point out that when serum ferritin <30ng/ml is an early indication of iron depletion, supplementation treatment is required as soon as possible.
