An Intrauterine transfusion (IUT) is a procedure that provides blood to a fetus, most commonly through the umbilical cord. [1] [2] It is used in cases of severe fetal anemia, such as when fetal red blood cells are being destroyed by maternal antibodies, or parvovirus B19 infection, homozygous alpha-thalassemia, or twin-to-twin transfusion syndrome.

Effectiveness was established based on achievement of transfusion independence, which is attained when the participant maintains a predetermined level of hemoglobin without needing any red blood cell transfusions for at least 12 months. Of 41 participants receiving betibeglogene autotemcel, 89% achieved transfusion independence. [5]
Higher platelet transfusion thresholds have been used in premature neonates, but this has been based on limited evidence. [19] There is now evidence that using a high platelet count threshold (50 x 10 9 /L) increases the risk of death or bleeding compared to a lower platelet count threshold (25 x 10 9 /L) in premature neonates. [20]
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
A large volume transfusion is the estimated entire blood volume of the baby (80 ml/kg) and is usually given during cardiac surgery. [1] A red cell exchange transfusion is usually given to treat severe hyperbilirubinemia or anemia in babies with hemolytic disease of the newborn. It removes neonatal red cells coated with maternal antibody and ...
Twin-to-twin transfusion syndrome (TTTS), also known as feto-fetal transfusion syndrome (FFTS), twin oligohydramnios-polyhydramnios sequence (TOPS) and stuck twin syndrome, is a complication of monochorionic multiple pregnancies (the most common form of identical twin pregnancy) in which there is disproportionate blood supply between the fetuses.
The FDA approved the drug under the brand name RhoGAM, with a fixed dose of 300 μg, to be given within three days (72 hours) postpartum. Subsequently, a broader peripartum period was approved for dosing which included prophylaxis during pregnancy. Within a year, the antibody had been injected with great success into more than 500,000 women.
