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
