Febrile nonhemolytic transfusion rxn

Increase temp 1°C or 2°F. Cytokines released by lymphocytes. Reduce incidence with leukoreduction

Allergic transfusion reaction

IgE mediated. Treat with antihistamines or epi if anaphylaxis. IgA deficient may need IgA deficient or washed units

Intravascular hemolysis

ABO incompatibility, rarely Kidd. Fever, chills, pain at infusion site, hypoTN, DIC back pain. +DAT, pink serum, schistocytes, hemoglobinuria

Extravascular hemolysis

Non-ABO. High bili, anemia. +DAT, spherocytes

Reporting time to FDA for fatality in transfusion rxn

24 hr by phone; within 7 days in writing

DHTR and DSTR

DHTR- hemolysis after 24hr. DSTR- new alloAb without hemolysis. +DAT (mf), high bili, microspherocytes. Kidd may be severe intravascular DHTR.

Septic (bacterial contamination)

Platelets more common but RBCs higher mortality. Platelets- staph. RBCS- gram negs esp Yersinia. Reason first 15-30 mL of donated blood are diverted (skin plugs).

TAGVHD

Donor lymphocytes attach host —> dermatitis, diarrhea, high LFTs, pancytopenia. May happen if donor is HLA XX/XX and recipient is HLA XX/YY. Prevent with irradiation.

TRALI

Most common cause of fatality. B/l lung infiltrates, PaO2:FiO2 < 300, O2 sat < 90% within 6 hrs. Donor antigranulocyte and antiHLA, esp due to plasma/platelets from multiparous female donor.

Post transfusion purpura

Multiparous woman with low plts after RBC or plt transfusion. Due to anti-HPA1a (Pla1). Treat with IVIg.

Platelet refractoriness

Platelet count increment < 7500


PCI = (increment x BSI/#plts transfused x10^11)


HLA alloimmunization, splenomegaly are causes.

TACO

CHF, elevated BNP, elevated pulmonary capillary wedge pressure. Volume overload. Go slow and diurese
