|
Symptoms: Hives w/ itching
Treatment: antihistamine while flow is slowed/stopped |
Urticaria |
|
Symptoms: - occurs after a few mL - Flushing of skin; no fever - coughing, resp.distress - Cramps, nausea, diarrhea
Treatment: Washed cells or plasma components from IgA deficient donors |
Anaphylactic shock |
|
Symptoms: - Chills, fever, cough - Bilateral pulmonary edema - Hypoxemia, hypotension
Treatment: - Respiratory support, steroids diuretics |

|
|
Symptoms: asymptomatic hemoglobinuria
Treatment: None; adhere proper protocol |
Physical or Chemical Hemolysis
|
|
Symptoms: - Fever, decreased hgb, jaundice - positive DAT *
Treatment: None; Check previous record;
- administer antigen (-) blood for all subsequent transfusions |
Hemolytic Delayed Transusion Reaction
|
|
Symptoms: - Fever, diarrhea, infection - Abnormal liver function - Cytopenia; usually fatal
Treatment: - Corticortisoids, cyclosporine - Methotrexate, azothioprine - Antithymocyte globulin
- Irradiated blood components containing lymphocytes w/ 25Gy before transfusion |
Acute Transfusion Assoc. Graft vs Host Disease
|
|
Symptoms: - scleroderma-like disease - sicca syndrome - interstitial pneumonitis - malabsorption |
Chronic Transfusion Assoc. Graft vs Host Disease |
|
Symptoms: - Self-limiting thrombocytopenia - Purpura; difficult to prevent
Treatment: - Corticosteroids - Therapeutic plasma exchange - High doses IV immunoglobulin |
Post-transfusion Purpura
|
|
Symptoms: - Muscle weakness, weight loss, jaundice
- Fatigue, arrythmias, diabetes
- Growth retardation in children |
Transfusion Induced Hemosiderosis
|
|
Symptoms: - Fever, fatigue, malaise, icterus - Arthralgia, hemolysis (malaria)
Treatment: - Quarantine components from unit; use volunteer blood supply and perform serologic tets
-Give Hepa B vaccine to workers
- Admi. Hepa Prophylaxis after HBsAg exposure |
Disease Transmission
|
|
What should you do during a Transfusion Reaction Investigation? |
1. Stop transfusion
2. IV line must be kept open w/crystalloids in case immediate treatment is necessary to overcome hypotension
3. Notify attending physician and blood bank
|
|
Transfusion Reaction Causes:
- antibody to RBC antigens
- antibody to wbc/plt/cytokines
- Ab soluble to Ag in plasma
- anti IgA |
Types:
- hemolytic
- febrile
- urticarial
- anaphylactic |
|
- routine anti sera and red cells tested:
- special anti sera tested: |
Daily
When used |
|
Antiglobulin reagent control testing:
Negative tests imply:
-
-
- |
- insufficient removal of serum prior to addition if AHG
- omission of AHG from procedure
- must repeat test |
|
- inheritance of antigen from father; mother has corresp. IgG
- Ab crosses placenta coating fetal cells = removal from circulation causing anemia and hyperbilirubinemia
- bilirubin (neurotoxin) causes brain damage (kernicterus) |
HDN |
|
Cause of HDN:
- inc. spherocytes - DAT weak/negative - delayed jaundice - bilirubin rarely >15mg% |
ABO |
|
Cause of HDN:
- inc. retuculocytes - DAT positive - immediate jaundice - bilirubin if ten >20mg% - exchange transfusion likely needed |
Rh |
|
- supplies antigen (-) blood
- group O, D, hgb S negative
- must be irradiated
- fresh less than 3 days old |
Intrauterine transfusion |
|
- reduces Ab and bilirubin levels by removing Ab coated cells
Accepted specimen: - maternal sample (best) - eluate from infant cells - infant serum |
Exchange transfusion |
|
Unit selection for exchange transfusion:
Group O if -
D negative if - |
- ABO HDN
- Rh HDN |
|
- given at 28 weeks to D (-) women and within 72hrs of delivery with D (+) infants
- 300ug covers 30mL whole blood fetal maternal hemorrhage |
Rh immune globulin |
|
- screening test for Rh immune globulin
- if (+) , Kleinhauer-Betke quantitates fetal maternal bleeding
- fetal cells resist (pink) - adult cells are ghost cells |
Rosette test |
|
- polymorphic system of antigens present on all nucleated cells
- genes located on chromosome 6
- typed using microlymphocytotoxicity |
HLA system |
|
Immunodominant structure of
H antigen:
B antigen:
A antigen: |
L-fucose
D-galactose
N-acetylgalactosamine |
|
A₁ and A₂ are sub-groups of A
What are some of their differences? |
A₁ cells are agglutinated while A₂ are not |
|
A₁ are anti a ____
A₂ and A₃ are anti a ____ |
(+)
(-) |
