[Transfusion reactions after SAG-M blood]

Area of Science:

• Transfusion Medicine
• Hematology
• Patient Safety

Background:

• Febrile non-hemolytic transfusion reactions (FNHTRs) are the most common adverse event associated with blood transfusions.
• Microaggregate accumulation in stored blood is a primary cause of FNHTRs.
• Reducing microaggregate load is crucial for improving transfusion safety.

Purpose of the Study:

• To evaluate the impact of using SAG-M (Saline Adenine Glucose Mannitol) red blood cell units on the incidence of transfusion reactions.
• To determine if SAG-M blood, which has reduced microaggregate content, leads to a lower rate of febrile reactions compared to traditional whole blood.

Main Methods:

• A retrospective analysis comparing transfusion reaction rates before and after the implementation of SAG-M blood.
• Data collection on transfusion reactions, specifically febrile reactions, associated with whole blood and SAG-M transfusions.
• Statistical comparison of reaction frequencies between the two blood product types.

Main Results:

• The frequency of transfusion reactions decreased significantly after the transition to SAG-M blood.
• The rate of reactions dropped from 0.83% with whole blood to 0.24% with SAG-M blood.
• This represents a substantial reduction in transfusion-related adverse events.

Conclusions:

• Switching to SAG-M red blood cells is an effective strategy for reducing the incidence of febrile transfusion reactions.
• Depletion of microaggregates in SAG-M blood directly contributes to improved patient safety during transfusions.
• The findings support the widespread adoption of SAG-M blood products to minimize transfusion complications.
