Two hours after a plasma transfusion, a patient develops acute dyspnea with bilateral pulmonary infiltrates. Blood pressure is low and there is no jugular venous distension. Which reaction is most consistent with these findings?
1Transfusion-associated circulatory overload
2Anaphylactic reaction
3Transfusion-related acute lung injury✓ 정답
4Bacterial contamination of the unit

The key is separating this from circulatory overload. Overload raises blood pressure and distends the neck veins. Hypotension and absent jugular venous distension together with pulmonary infiltrates point instead to transfusion-related acute lung injury.
