Abstract:
Blood filters have been available since the 1930s. In this review we evaluate the role of microaggregate filters (MF) in certain transfusion complications, namely non-haemolytic febrile transfusion reactions (NHFTR), pulmonary injury, thrombocytopenia, fibronectin depletion and histamine release. We review the latest generation of leucocyte depleting filters and discuss their role in preventing alloimmunisation, immunosuppression and CMV transmission. Finally, we provide a rationale for the role of blood microfiltration in the present day practice of intensive care medicine.
Insights
Blood microfilters help prevent transfusion complications like febrile reactions and lung injury. Modern leucocyte depleting filters also reduce immune reactions and CMV transmission, supporting their use in intensive care.
Area of Science:
- Hematology
- Transfusion Medicine
- Critical Care
Background:
- Blood filters have been utilized since the 1930s.
- Microaggregate filters (MF) have been investigated for their impact on transfusion complications.
Purpose of the Study:
- To evaluate the role of microaggregate filters in transfusion complications such as non-haemolytic febrile transfusion reactions (NHFTR), pulmonary injury, thrombocytopenia, fibronectin depletion, and histamine release.
- To review the latest generation of leucocyte depleting filters and their role in preventing alloimmunisation, immunosuppression, and CMV transmission.
- To provide a rationale for the use of blood microfiltration in intensive care medicine.
Main Methods:
- Literature review of microaggregate filters and their effects on transfusion reactions.
- Review of current leucocyte depleting filter technology.
- Analysis of the clinical rationale for blood microfiltration in intensive care.
Main Results:
- Microaggregate filters are associated with mitigating NHFTR, pulmonary injury, thrombocytopenia, fibronectin depletion, and histamine release.
- Leucocyte depleting filters are effective in preventing alloimmunisation, immunosuppression, and CMV transmission.
- Blood microfiltration is deemed essential in contemporary intensive care practices.
Conclusions:
- Blood microfiltration plays a crucial role in managing transfusion complications and preventing adverse events.
- Leucocyte depletion via filtration is vital for immunological safety in transfusions.
- The use of blood filters is well-justified in intensive care medicine.
