贫血乃孕妇之常见病。造成妊娠期贫血的因素是多方面的,应予重视,加以识别,有效防治,以利母婴健康。一、生理性稀释性贫血:正常妊娠,红细胞、血红蛋白及血球容积均会低于非妊娠时。其原因是为了灌注胎盘、乳房内增多的血管,血浆容量比正常增多达40～50%。红细胞容积虽也相应增加,但仅达17～25%,造成生理性的稀释性贫血(Dilutional anemia)。此种变化从孕期第6周开始,24周明显,第34周达高峰伴红细胞形态增大。产后6～8周,血浆容量回复
Anemia is a common disease in pregnant women. Factors causing anemia during pregnancy are many and should be paid attention to, identify, and effective prevention and control to facilitate the health of mothers and children. First, physiological dilutional anemia: normal pregnancy, red blood cells, hemoglobin and hematocrit will be lower than non-pregnancy. The reason is to perfuse the placenta, increased blood vessels in the breast, the plasma volume increased by up to 40 to 50% more than normal. Although a corresponding increase in the volume of red blood cells, but only up to 17 ~ 25%, resulting in physiological dilutional anemia. This change from the first 6 weeks of pregnancy, 24 weeks significantly, the first 34 weeks reached a peak with red blood cell morphology increased. Postpartum 6 to 8 weeks, plasma volume response
