문제
During rapid massive transfusion, a patient develops prolonged QT and hypotension. Which laboratory abnormality can result from the citrate load?
1Severe hypercalcemia
2Isolated hyperalbuminemia
3Increased ionized calcium
4Decreased ionized calcium✓ 정답
해설
Citrate in transfused components binds calcium. Rapid large-volume exposure can cause ionized hypocalcemia, especially when citrate metabolism cannot keep pace.
