quick question,
Studying for step II, just read in Crush step 2 "...during prenatal care, check Rh antibodies at 1st visit, if positive, do NOT give RhoGAM-you are too late"
well what then do you do, it does not say? Anyone out there know

I could be wrong, but I don't think there is anything you can do for mom...

...But you have to monitor baby for hydrops fetalis (high-output heart failure, edema, ascites), and hepatosplenomegaly which you can detect on ultrasound. I think to prevent hemolytic anemia of the newborn you do intrauterine transfusions, which might have to be done several times during the pregnancy.

intrauterine transfusions

This is, I believe, the Rx of choice. Not advisable to let it get to this situation, however.

Serial amniocentesis are performed @ around 20 weeks if the Rh titer is greater than 1:16. Amniotic fluid is analyzed for bilirubin and this is plotted on a curve which predicts disease severity. When hematocrit falls too low, intrauterine transfusions are done.
