[3] [8] 92% of women who develop an anti-D during pregnancy do so at or after 28 weeks gestation. [11] [9] [12] In an RhD negative mother, RhIG can temporarily prevent sensitization of the maternal immune system to RhD antigens, with each 100 μg of anti-D being able to neutralize about 4 mL of fetal blood. [13]
Anti-D immune globulin is usually recommended in those who are Rh-negative. [4] Occasionally, surgery is required. [1] About 30% of women have bleeding in the first trimester (0 to 14 weeks gestational age). [1] [5] Bleeding in the second trimester (12 to 24 weeks gestational age) is less common. [6]
The term "Rh Disease" is commonly used to refer to HDFN due to anti-D antibodies, and prior to the discovery of anti-Rh o (D) immune globulin, it was the most common type of HDFN. The disease ranges from mild to severe, and occurs in the second or subsequent pregnancies of Rh-D negative women when the biologic father is Rh-D positive.
Thus, if the initial titer is 1:4 and stable but increases at 26 weeks' gestation to 1:8, assessment with MCA Doppler velocity at that point is reasonable. However, if the patient presents in the first trimester with a 1:8 titer that remains stable at 1:8 throughout the second trimester, continued serial antibody titers are appropriate.
[14] [12] However, all NSAIDs showed association with structural cardiac defects with usage during the early weeks of pregnancy. When ibuprofen and naproxen are used within the third trimester, there is a significant increase in the risk of premature closure of the ductus arteriosus with primary pulmonary hypertension in the newborn.

Normally, no extra medical intervention is required when maternal Rh status is RhD+, nor RhD- mothers going through first pregnancy. However, in the case of a sensitized RhD- mother (previously conceived an RhD+ child) and the fetus being Rh+, medication such as an anti-D immunoglobulin, called RhoGAM, will be given to the RhD- mother ...
