| Special Instructions: |
No specimen is needed if blood bank
has record of Rh typing (must be Rh negative) and recent antibody screen (must
not already be sensitized to Rh(d) antigen). Indications: Rh immune globulin
(anti-D IgG, or RhIg is administered IM to Rh(d) negative mothers at the 28th
week of pregnancy, within 72 hours post-delivery of an Rh(d) positive infant,
post-abortion, trauma, external fetal manipulation, invasive procedures
involving the amniotic cavity, e.g. amniocentesis. It is also given to
non-pregnant Rh(d) negative individuals after transfusion of a Rh(d) positive
blood product that contains small numbers of red cells, such as platelets. For
patients given repeated doses of platelets over a period of time, it will be
necessary to give additional doses every 3 weeks, since the half-life of IgG is
approximately 21 days. It is not necessary to give RhIg after transfusion of a
cellular blood components, e.g. FFP or cpptand it is impractical to attempt to
treat an individual who has received an entire unit of Rh-positive RBC. RhIg is
not indicated in persons who are already immunized to the Rh(d) antigen. This
product carries no risk of infectious disease. Dose: the standard 300 mg dose of
Rh(d) immune globulin will protect against immunization by up to 15 mL packed
red cells (approximately 25-30cc of whole blood), or up to 30 units of random
platelets or 3 units of apheresis platelets. In Rh(d) negative women who give
birth to Rh(d) positive infants, a quantitative test for the presence of fetal
blood in maternal circulation should be performed (kleihauer-betke) by the blood
bank to determine if a single dose of RhIG is sufficient to prevent
immunization. The 72-hour treatment limit is arbitrary and treatment should not
be withheld even if more than 72 hours have elapsed. |
