-serum vitamin and minerals levels differ during pregnancy-most are lower, some vary and some levels increase-hemodilution causes the decrease in concentration of vitamins and minerals - I,Ca, P,Mg, Se, Zn, Vit B12,B6, C decreased-iron, folic acid, vit D variable-copper, vitamins a and e increased Physiological adaptation in pregnancy leads to physiological anemia of pregnancy. This is because the plasma volume expansion is greater than red blood cell (RBC) mass increase which causes hemodilution. Normal pregnancy increases iron requirement by 2–3 fold and folate requirement by 10–20 fold. Major causes of anemia are: the majority of liver tests remain in the normal range in pregnancy except those produced by the placenta (alkaline phosphatase, alphafetoprotein) or impacted as a result of hemodilution (albumin, hemoglobin). Of note, during pregnancy, cardiac output is increased by 40–45% with substantive increases to the renal, uterine, and skin systems. In pregnancy, the normal Hgb reference range is 11-12 g/dL. Critical values for Hgb include: Hgb<5 g/dL and Hgb>20 g/dl which can cause heart failure and hemoconcentration-clotting, respectively Introduction: During pregnancy women undergo several structural and physiological changes almost in most body systems including the hematological profile.

Pregnant women experience a decrease in blood plasma or an increase in blood cells Preeclamptic patients showed a significantly reduced cardiac output and central venous pressure compared with normal pregnant women. It has already been This process is called “hemodilution” because the blood cells get diluted when the plasma increases. Hemodilution is a healthy response to pregnancy and a Nov 30, 2016 Keywords: Pregnancy, anemia, ferritin, vitamin B12, folate. Introduction (Table 4).

2021-03-16 · Outside of pregnancy, a normal platelet count ranges from 150,000 to 450,000/µL (platelets per microliter of blood). It's normal for your platelet count to dip by a few thousand during pregnancy, due in part to hemodilution: the body makes more plasma during pregnancy, so the total number of platelets per volume of blood will be lower. Hemodilution is an important component of CPB practice which has allowed safe and effective tissue perfusion without the need for blood products. The quest to determine the optimal level of hemodilution for patients has been difficult owing to the large variability in the tolerance of both patients and specific tissues to hemodilution. Hemodilution and physiologic anemia Fluid retention → increased hematopoiesis, yet cannot match the increased fluid retention, therefore a ↓ hematocrit. Iron supplementation is necessary; only nutrient not sufficient with normal diet. haemodilution: ( hē'mō-di-lū'shŭn ) Increase in the volume of plasma in relation to red blood cells; reduced concentration of red blood cells in the circulation.

This combined with the hemodilution state leads to a mean platelet count that is slightly lower than that in the non-pregnant state . An increased platelet production can be inferred from the increase in With normal pregnancy, blood volume increases, which results in a concomitant hemodilution.
