Question:
A young donor came to the blood bank for the first time for platelet apheresis with platelet count of 1.9L. During the course he developed paresthesias, circumoral numbness during donation. His vitals remain stable though. ECG showed tachycardia with ST-T changes. What is the reason for his symptoms?

Options:
A. Hypovolemic shock
B. Hypocalcemia
C. Seizures
D. Allergic reaction'

[2025-10-01T18:36:43.074647] [PI reasoning] **Evaluating symptoms during platelet apheresis**

I need to understand the reasons behind symptoms like paresthesias and circumoral numbness during platelet apheresis. It looks like the anticoagulant solution used can chelate calcium, which might lead to hypocalcemia and cause those symptoms along with possibly more serious issues. So, the answer seems to point towards hypocalcemia. I should definitely look for some solid evidence, maybe check the Blood Transfusion guidelines from 2017. A quick hybrid search on related topics sounds like a good plan!
