    2. 30/11/2549 MD-3 /49 2 Transfusion Reaction is any unfavorable transfusion-related event occurring in a patient during or after transfusion of blood components

    3. 30/11/2549 MD-3 /49 3 Immediate and Delayed Transfusion Reaction

    4. 30/11/2549 MD-3 /49 4

    5. 30/11/2549 MD-3 /49 5 Signs and Symptoms of AHTR Chills , fever Facial flushing Hypotension Renal failure DIC Chest pain Dyspnea Generalized bleeding Hemoglobinemia Hemoglobinuria Shock Nausea Vomitting Back pain Pain along infusion vein

    6. 30/11/2549 MD-3 /49 6 Acute Hemolytic Transfusion Reactions

    7. 30/11/2549 MD-3 /49 7 Pathophysiology Two mechanisms for RBCs destruction 1) Intravascular hemolysis 2) Extravascular hemolysis

    8. 30/11/2549 MD-3 /49 8 Management of AHTR Stop the transfusion Keep IV fluid Notify patients physician and blood bank Take care of patient Perform bedside clerical checks Return unit, set to blood bank Collect appropriated post transfusion blood sample for evaluation Document reaction

    9. 30/11/2549 MD-3 /49 9 Laboratory investigation for AHTR sample from blood bag Repeat ABO, Rh, Ab screening Patient sample Pre Tx sample Repeat ABO, Rh, Ab screening Post Tx sample Repeat ABO, Rh, Ab screening, DAT, CBC, UA, Bilirubin, BUN, Cr, Coagulation screening Repeat compatibility test - Pre Tx sample & Donor unit - Post Tx sample & Donor unit

    10. 30/11/2549 MD-3 /49 10 Treatment of AHTR Depends on Amount of incompatible blood transfused Specificity of the offending antibody Clinical severity of the reaction

    11. 30/11/2549 MD-3 /49 11

    12. 30/11/2549 MD-3 /49 12

    13. 30/11/2549 MD-3 /49 13

    14. 30/11/2549 MD-3 /49 14

    15. 30/11/2549 MD-3 /49 15 Delayed Hemolytic Transfusion Reaction Most often the result of an anamnestic response (transfusion, pregnancy, transplantation ) Mild clinical signs and symptoms Unexpected or unexplained decreased in Hb or Hct after transfusion should be investigate as possible DHTR

    16. 30/11/2549 MD-3 /49 16 Delayed Hemolytic Transfusion Reaction Pathophysiology - 2 types of DHTR 1) secondary (anamnestic) response to transfused RBCs ?3 7 day after Tx 2) primary alloimmunization longer - Extravascular hemolysis sensitized RBCs ? removed by RES

    17. 30/11/2549 MD-3 /49 17 Delayed Hemolytic Transfusion Reaction Signs & Symptoms mild fever or fever with chill mild anemia mild to moderate jaundice Uncommon ? hemoglobinemia, Hemoglobinuria, shock, renal failure

    18. 30/11/2549 MD-3 /49 18 Delayed Hemolytic Transfusion Reaction Therapy and Prevention - Goal of therapy is prevention - Treat severe complication if necessary - Alert to history of sensitization (previous transfusion, Pregnancy, transplantation)

    19. 30/11/2549 MD-3 /49 19 Febrile Nonhemolytic Transfusion Reaction ( FNHTR) Definition 1oC temperature rise associated with transfusion, no medical explanation other than blood transfusion

    20. 30/11/2549 MD-3 /49 20 Pathophysiology of FNHTR - Patients Leukocyte antibodies (HLA Ab) - Blood donors leukocytes in transfused blood

    21. 30/11/2549 MD-3 /49 21 Febrile Nonhemolytic Transfusion Reaction Signs & Symptoms Fever with or without chills most symptoms are mild severe reaction :- hypotension, cyanosis, tachycardia, tachypnea, dyspnea, cough etc.

    22. 30/11/2549 MD-3 /49 22

    23. 30/11/2549 MD-3 /49 23 Allergic Transfusion Reactions Probably the most frequent kind of reaction Pathophysiology Allergen Reagin (IgE,IgG) complex attach mast cell histamine/leukotrienes Allergic reactions (urticaria)

    24. 30/11/2549 MD-3 /49 24 Allergic Transfusion Reactions Signs & Symptoms - Urticaria - severe reactions are rare Therapy & Prevention - Antihistamine - Plasma deficient blood components

    25. 30/11/2549 MD-3 /49 25 Anaphylactic and Anaphylactoid reactions Anaphylaxis can range from mild urticaria to severe shock and death Pathophysiology - IgE antibody to IgA in donor plasma (anti-IgA antibodies)

    26. 30/11/2549 MD-3 /49 26 Anaphylactic and Anaphylactoid reactions Signs & Symptoms - Anaphylactic ? coughing, dyspnea, nausea, emesis, bronchospasm, flushing of skin, chest pain, hypotension, abdominal cramps, diarrhea, shock, and death. - Anaphylactoid (less severe) ? urticaria, periorbital swelling, dyspnea, or perilaryngeal edema

    27. 30/11/2549 MD-3 /49 27 Anaphylactic and Anaphylactoid reactions Therapy and Prevention Stop transfusion Keep IV line open Medication :- epinephrine, corticosteroid Wash RBCs and blood components Transfuse IgA deficiency blood

    28. 30/11/2549 MD-3 /49 28 Transfusion-related Acute Lung Injury (TRALI) Pathophysiology Leukocyte Ab in donor react with pt. leukocytes Activate complements Adherence of granulocytes to pulmonary endothelium with release of proteolytic enz.& toxic O2 metabolites Endothelial damage Interstitial edema and fluid in alveoli

    29. 30/11/2549 MD-3 /49 29 Transfusion-related Acute Lung Injury (TRALI) Acute and severe type of transfusion reaction Symptoms and signs Fever Hypotension Tachypnea Dyspnea Diffuse pulmonary infiltration on X-rays Clinical of noncardiogenic pumonary edema

    30. 30/11/2549 MD-3 /49 30 Transfusion-related Acute Lung Injury (TRALI) Therapy and Prevention Adequate respiratory and hemodynamic supportive treatment If TRALI is caused by pt. Ab ? use LPB If TRALI is caused by donor Ab ?no special blood components
