RhIg administration and birth of multiples

[Deny Morlino]

What sort of policy do others follow when a Rh negative mother gives birth to two or more Rh positive children at a time with regard to RhIg administration? I checked AABB's Technical Manual and could not find a reference for the above described situation. Instinct tells me to perform a fetal bleed screen and administer RhIg adjusted for the fetal volume detected. Should any additional dose be given if the fetal bleed screen is negative (other than the recommended single dose obviously)? Opinions please.

Thanks David.

I agree as well. It dosen't really matter how many babies there are, it's the amount of D+ baby blood loose in mom's system that is the factor.

Agreed!

I did not think my logic was faulty, but had some conflicting recommendations by other bbankers. As usual this site is invaluable.
