When do you give a RhIg?

1. RhIg should be given at 26 to 28 weeks gestation if the woman is D-negative and the antibody screen is negative for anti-D. If the first prenatal visit is earlier than 26 weeks gestation, the antibody screen should be repeated at 26 weeks prior to administration of RhIg.

What is RhIg in blood bank?

Rh immune globulin (RhIG) is a medication that contains antibodies to Rh antigen D (RhD), which may be present on the surface of red blood cells (RBCs) in some individuals. It prevents a person’s immune system from recognizing RhD, thus suppressing a potentially fatal immune reaction.

Do platelets need to be Crossmatched?

Platelet transfusions from RhD-positive donors to recipients with anti-D antibodies do not result in hemolysis, because they contain very few RBCs. Only products containing >2 mL of incompatible RBCs require a serologic crossmatch per AABB standards.

Do platelets need to be Rh compatible?

Platelets do not express Rh antigens, but platelet components contain residual intact RBCs or fragments that can result in alloimmunization to RBC antigens, including RhD.

Why is RhIG given?

Rho(D) immune globulin (RhIG) is a medication used to prevent RhD isoimmunization in mothers who are RhD negative and to treat idiopathic thrombocytopenic purpura (ITP) in people who are Rh positive. It is often given both during and following pregnancy.

Who is a candidate for RhIG?

RhIG is given when: you’re 26 to 28 weeks pregnant, and when you deliver if your baby is Rh positive. you have certain tests, treatments, or procedures (such as amniocentesis or chorionic villous sampling) during your pregnancy.

What is RhIG used for?

Rho(D) immune globulin (RhIG) is a medication used to manage and treat Rh-negative pregnancies and immune thrombocytopenic purpura.

How is RhIG calculated?

Calculating RhIG Dosage

  1. Volume of fetal bleed: % fetal cells x maternal blood volume.
  2. Maternal blood volume: 70 mL/kg x weight (kg) (assume 5,000 mL if maternal information is unknown)

How do nurses transfuse platelets?

Platelets are transfused at the bedside through intravenous tubing with an in-line filter (screen filter of 170-260 micrometer pore size) to remove fibrin clots and large debris. The tubing can be primed with normal saline or blood product itself.

Does platelet transfusion need blood group matching?

Thus, unlike RBC transfusions, there really are no ABO compatible platelet transfusions. Platelet transfusions should be classified as either ABO identical or nonidentical.

Does blood type matter for platelet transfusion?

Does Rh matter with FFP?

FFP does not need to be Rh-compatible; anti-D prophylaxis is not necessary in Rh D-negative recipients of Rh D-positive FFP (Grade of recommendation: 1C+)3,4.
