Antenatal and intrapartum neonatal hemorrhagic anemia causes and diagnosis

Normal hemoglobin and reticulocytes was discharged to continue oral iron anemia corrected 1 year (2-3mg · kg ~ · d). 2 to discuss the classification of newborn blood loss 2.1 neonatal hemorrhagic anemia for many reasons,[link widoczny dla zalogowanych], generally divided into acute and chronic blood loss, loss of sister. According to the time blood loss, blood loss into antenatal, intrapartum blood loss and blood loss after birth. This group does not include blood loss anemia after birth. 2.2 neonatal hemorrhagic blood loss because of prenatal 2.2.1: ① fetal blood loss of a parent: the fetal blood circulation through the placenta into the maternal blood. Disparity between the severity of clinical symptoms, depending on the speed and extent of blood loss. Most chronic blood loss for a long time, no jaundice, liver and spleen is not, whether pale or tachycardia varies according to the severity of anemia. Children generally in good spirits, but if the labor to the mother when the symptoms of acute severe blood loss, blood loss can occur above the cylinder capacity of 40mL to reduce shock,[link widoczny dla zalogowanych], manifested as pale, weak, heart rate, difficulty breathing, decreased hemoglobin. ② one twin to another fetus blood loss: about 70% of identical twin fetuses of a single chorionic placenta, blood vessels almost all the same, 15% had a fetal blood to another phenomenon of the fetus. Fetal blood loss more than thin, pale, the spirit of good, if labor may occur in shock symptoms. ③ placenta blood loss: the loss of blood to the placenta or the placenta into the maternal but not after. Prenatal blood loss anemia is often severe, neonatal and birth asphyxia have pale, need urgent and effective rescue and blood transfusion. 3 cases with this group prenatal blood loss,[link widoczny dla zalogowanych], are caused by fetal blood loss of a parent, his mother HbF, significantly higher than normal. 2.2.2 intrapartum blood loss: due to the placenta (such as placenta previa, placental abruption,[link widoczny dla zalogowanych], placental rupture,[link widoczny dla zalogowanych], multi-leaf of the placenta) and blood loss anemia caused by umbilical cord blood. Town of clinical manifestations of acute blood loss, see the fetus pale, weak cry, irregular breathing, rapid heart rate, low heart sound blunt, low blood pressure, rapid and significant decrease of hemoglobin, showing large cell anemia, serum iron normal at birth. For newborns born with obvious clinical manifestations, it is not difficult to diagnose. This reminds clinicians should pay special attention during surgical procedures to prevent accidental injury caused by umbilical cord and placenta blood loss. 2 cases in this group when the umbilical cord rupture caused by birth, his mother HbF normal.
