Q

prego 36 weeks, in labor, moderate blood, mom is A Rh-Negative
serum anti-D antibody titer is positive

fetal heart montior: SINUSOIDAL wave forms

what is most likely causing fetal heart rate pattern?

A

Rh isoimmunization

Rh(D)-negative moms are at high risk of forming anti-Rh(D) antibodies (Rh isoimmunization) – if exposed to blood from a Rh(D)-Positive fetus

it can cause hemolytic anemia – erythroblastosis fetalis (sinusoidal wave forms) 2/2 to Rh isoimmunization

next baby will die

Prevent it by giving RhoGAM at 28 weeks in Rh(D)-negative mothers
