|Mrs. JS is a 36-year-old expectant mother of 3 booked for Cesarian section (C/S) due to transverse position of baby.
Normal test results
Blood not transfused
Patient returned to Operating Room for emergency hysterectomy due to uncontrolled bleeding
Transfused with 11 units crossmatch-compatible group O Rh positive RBCs and 8 FFP
Discharged with daughter
See these workups:
DAT positive with anti-IgG
Antibody screen and all units positive at IAT
Suspect delayed hemolytic transfusion reaction
Color of plasma is a key indicator
Eluate important to begin ASAP
Plasma panels but they are of little use in determining specificity
Finding pre-transfusion specimen is a gold mine to resolution of this case.
After reviewing the case summary, consider these questions:
What are the common symptoms of delayed transfusion reaction?
Why was prewarm LISS used to crossmatch donor units with the post reaction specimen?
Why was phenotype matched blood crossmatched?
