Myocardial ischemia: A complication of r ritodrine tocolysis

Demonstration of leakage of fetal blood into the maternal circulation secondary to damage in the placental barrier, as demonstrated in the above case reports, may have additional importance in the Rh-negative woman. Further studies will show if Rh-negative women with similar conditions should receive Rho (D antigen) immune globulin as is presently done in Rh-negative women undergoing ilmniocentesis.
