Hi Carol,
I had a failed platelet transfusion while I was being prepared for a preventative double mastectomy due to having the BRCA1 gene.
All hell broke loose about 9 minutes into the transfusion. My blood pressure went from 144/75 to 60/30 in minutes. I threw up, had a bowel movement, my temperature spiked and I itched all over. The surgery was cancelled due to the severe allergic reaction.
The Doctor mentioned that she had given my B+ platelets (I’m O negative) and that some red blood cells might have gotten into the platelets.
I did some research and found that up to 30% of people have a reaction to a platelet transfusion.
I would urge your Dr. to match the platelets to your blood type, even though normally platelets do not need to match your blood type.
Best of luck to you and I hope everything goes well!
