Preterm infants are often anemic and typically experience heavy blood losses from frequent laboratory testing in the first few weeks of life. [4] Although their anemia is multifactorial, repeated blood sampling and reduced erythropoiesis with extremely low serum levels of erythropoietin (EPO) are major causative factors.
[12] Hypothyroidism and chronic kidney disease [13] [14] Parasitic infestations: some examples are hookworm or Plasmodium species [7] Bacterial or viral infections. Iron deficiency is the most common cause of anemia in the pregnant woman. During pregnancy, the average total iron requirement is about 1200 mg per day for a 55 kg woman.
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
Mirror syndrome, triple edema or Ballantyne syndrome is a rare disorder affecting pregnant women. It describes the unusual association of fetal and placental hydrops with maternal preeclampsia.
Anemia (also spelled anaemia in British English) is a blood disorder in which the blood has a reduced ability to carry oxygen.This can be due to a lower than normal number of red blood cells, a reduction in the amount of hemoglobin available for oxygen transport, or abnormalities in hemoglobin that impair its function.
Medications can have adverse effects and cause nutritional anemia as well. Medications that stop the absorption of iron in the gut and cause bleeding from the gut (NSAIDs and Aspirin) can be culprits in the development of this condition. Hydrocortisones and valproic acid are also two drugs that can cause moderate bleeding from the gut.
A low hematocrit level is a sign of a low red blood cell count. One way to increase the ability of oxygen transport in red blood cells is through blood transfusion, which is carried out typically when the red blood cell count is low. Prior to the blood transfusion, hematocrit levels are measured to help ensure the transfusion is necessary and safe.
A large study followed children born between 22 and 25 weeks until the age of 6 years old. Of these children, 46% had moderate to severe disabilities such as cerebral palsy, vision or hearing loss and learning disabilities, 34% had mild disabilities, and 20% had no disabilities; 12% had disabling cerebral palsy.
