Summary
Transfusing stored blood in dogs increased lymph flow and lung fluid, potentially due to microaggregates. This highlights risks for patients with lymphatic issues.
Area of Science:
- Physiology
- Immunology
- Transfusion Medicine
Context:
- Blood transfusions are common medical procedures.
- Stored blood may contain microaggregates.
- Lymphatic system plays a role in fluid balance and immune response.
Purpose:
- To investigate the physiological effects of transfusing stored citrated blood in mongrel dogs.
- To determine the influence of blood storage time and microaggregates on lymph flow and vascular permeability.
Summary:
- Transfusion of citrated blood in dogs led to increased lymph flow in thoracic and right lymphatic ducts.
- Enhanced vascular permeability and pulmonary fluid accumulation were observed.
- The severity of these effects correlated with blood storage duration and the presence of thrombo-leukocytic microaggregates.
Impact:
- Findings suggest potential complications of hemotransfusions, particularly in individuals with compromised lymphatic systems.
- Highlights the importance of considering blood storage time and microaggregate load in transfusion safety.
- Raises questions about the sequelae of blood transfusions in patients with lymphatic system incompetence.
