When a Rh negative mom carries an Rh positive baby the concern for the fetus is?
erythroblastosis fetalis
What is hymolytic disease?
Hemolytic disease of the newborn is also known as erythroblastosis fetalis. It is a condition that develops in a fetus when the mother and fetus have incompatible blood types.
Which class of antibody produced by a pregnant woman may attack RBCs in her fetus resulting in erythroblastosis fetalis?
IgG molecules.
The condition in which rh plus red blood cells of a fetus are attacked by anti-Rh antibodies of the fetus Rh-mother is called?
Heamolytic disease of the newborn or Erythroblastosis Fetalis
Who is the most harmed when erythroblastosis fetalis occurs?
Erythroblastosis fetalis is a potentially life threatening blood disorder in fetus or new born infant. It happens when the mother possesses Rh negative blood where the foetus posses Rh positive blood which turns it weak anaemic nd jaundiced or in severe case death of the foetus occurs..
Why does erythroblastosis fetalis occur with a second pregnancy and normally not the first pregnancy?
The mother is exposed to fetal blood during childbirth or abortion. The Rh+ proteins on the surface of fetal erythocytes can trigger an immune response in the mother. This creates antibodies in the mother and memory lymphocytes that are able to create more antibodies. In the second pregnancy with a fetus with Rh factor, the antibodies in maternal blood can cross the placenta to the fetus and attack the fetus's erythocytes to cause erythroblastosis fetalis. The maternal blood in the first pregnancy does not contain such antibodies to cause the problem because the mother has never been exposed to the Rh factor until the time of first childbirth with the antigen.

Why does the first born child not have erythroblastosis fetalis?
The first child born of a female is generally not at risk for erythroblastosis fetalis because the mother's immune system has not been exposed to the fetal blood antigens and therefore has not produced antibodies against it. However, by the second pregnancy there is a slight risk if the blood type of the fetus is not compatible with the mother's blood type.
What are the most common diseases of new born baby?
I'm not sure If I'm right. Hemolytic - Means Breaking down Red Blood Cells. Erythroblastosis - Refers to making of immature red blood cells. Fetalis - Refers to Fetus.
Which baby gets erythroblastosis fetalis?
The second baby, normally. Erythroblastosis Foetalis is when a baby with a positive blood group is born to a mother of a negative blood group, and the mother has been 'sensitized' during a previous pregnancy. The mother's body identifies the fetus as a 'foreign' protein and her body's immune system tries to fight the foreign protein, much like an allergic reaction.
How does erythroblastosis fetalis develop?
It happens when the father is of a positive blood group (having Rhesus (Rh) factor) and mother of a negative blood group (devoid of Rh factor), the fetes' blood group will be of the positive type, i.e., having Rh factor as having Rh factor is a dominant trait and can mask the negative blood group. So, this creates problems for the kid as well as mother during pregnancy. Usually, the first pregnancy will not have much complications. But, the second pregnancy onwards, the antibodies present in the mother from the first pregnancy will be present and is harmful for the fetes.

Erythroblastosis fetalis?
DefinitionErythroblastosis fetalis is a potentially life-threatening blood disorder in a fetus or newborn infant. This article provides a general overview. For more detailed information see the specific disorder:ABO incompatibilityRh incompatibilityAlternative NamesHemolytic disease of the newbornCauses, incidence, and risk factorsErythroblastosis fetalis develops in an unborn infant when the mother and baby have different blood types. The mother produces substances called antibodies that attack the developing baby's red blood cells.The most common form of erythroblastosis fetalis is ABO incompatibility, which can vary in severity.The less common form is called Rh incompatibility, which can cause very severe anemia in the baby.SymptomsSymptoms in a newborn baby may include:AnemiaEdema (swelling under the surface of the skin)Enlarged liver or spleenHydrops (fluid throughout the body's tissues, including in the spaces containing the lungs, heart, and abdominal organs)Newborn jaundiceSigns and testsSpecific tests depend on the type of erythroblastosis, but may include:Complete blood countBilirubin levelBlood typingTreatmentAfter birth, depending on the severity, a transfusion usually needs to be performed.For specific treatment information, see:ABO incompatibilityRh incompatibilityExpectations (prognosis)The severity of this condition can vary widely. In some instances, the baby has no symptoms of the disease. In other cases, it can lead to death of the baby before or shortly after birth. It can be treated before birth by intrauterine transfusion.ComplicationsComplications depend on the specific type of erythroblastosis fetalis.PreventionThe most severe form of this disease, Rh incompatibility, can be prevented if the mother takes a medicine called RhoGAM at certain times during and after pregnancy. If you have had a baby with this disease, be sure to talk with your doctor if you plan on having another baby.ReferencesGruslin AM, Moore TR. Erythroblastosis fetalis.
