Situation: A 35-year-old female patient with
blood type A+ gravida 4 para 3 (3,0,1,3) gave birth to a live term
baby boy via emergency cesarean section, 2600mg, with an APGAR
score of 8-9, 39-40 weeks AOG s/p hysterectomy. The mother suffered
heavy bleeding during delivery because of placenta increta which
also warranted the hysterectomy. She was transfused with 2 units of
type O+ packed RBC during the procedure. After 7 days, the patient
developed ictericia, jaundice, and low-grade fever at 38.1C but
otherwise feeling well.
Question: What particular step in packed
RBC preparation that may have contributed to this case?
