Question
An O-type blood mother, pregnant at 13 weeks, inquires about the risk of her A-type blood spouse in giving birth to a hemolytic child, asking about the probability and the methods to deal with it.
Answer
Doctors explain that although the incidence of Rh hemolytic disease is low, it can lead to severe consequences, including fetal death or serious jaundice problems. For Rh-negative mothers, if they carry an Rh-positive fetus, there may be a mild hemolytic reaction during the first pregnancy, but the risk increases during subsequent pregnancies. Currently, there is a preventive injection of Rh (D) IgG, which is recommended to be used within 72 hours after the birth of an Rh-positive baby to reduce the risk of hemolytic reactions during subsequent pregnancies.
