- How did the authors use group A thawed plasma in this study?
- Only after determining the anti-B isohemagglutinin titer in the unit
- For all patients regardless of their historical blood group
- For all patients within the first 24 hours of hospitalization
- For patients if their blood group was unknown
- Only if group AB thawed plasma was not available for patients with unknown blood group
- How many of the 385 patients in this study who needed emergency release group A plasma were subsequently found to be compatible with it?
- 10 (2.6%)
- 44 (11%)
- 193 (50%)
- 289 (75%)
- 325 (84%)
- How many of the 23 group B or AB patients who received incompatible group A plasma had a hemolytic transfusion reaction?
- 0
- 2
- 5
- 17
- 19
- How many of the 10 patients who received incompatible plasma demonstrated visible hemolysis in their posttransfusion specimen which the authors attributed to anti-B isohemagglutinins in the group A plasma?
- 0
- 2
- 5
- 7
- 9
- What do the authors conclude about the use of group A plasma for emergency release transfusion?
- It is an acceptable alternative to group AB plasma when the patient's blood group is unknown or compatible plasma is not available
- It is not necessary to determine the anti-B isohemagglutinin titer of the group A plasma before release
- There were no adverse outcomes attributed to incompatible plasma transfusion
- A blood sample for compatibility testing should be requested at the time of emergency release so that the patient can be switched to ABO-identical or ABO-compatible plasma
- All of the above
