[Trauma to the blood during assisted circulation].

Area of Science:

• Hematology
• Biomedical Engineering
• Cardiovascular Research

Context:

• Assisted circulation devices are crucial in managing severe cardiovascular conditions.
• Understanding blood trauma is vital for optimizing device performance and patient outcomes.
• Previous research has explored various aspects of blood-device interactions.

Purpose:

• To investigate the effects of different assisted circulation methods on blood components.
• To compare the degree of blood trauma induced by left ventricular shunting, aorta-aortic counter-pulsation, and balloon pump counter-pulsation.
• To identify the assisted circulation method with the least damaging effect on blood.

Summary:

• Experiments and clinical studies examined blood trauma from assisted circulation.
• Morphological changes in red blood cells and altered aggregation properties of platelets were observed.
• Aorta-aortic counter-pulsation demonstrated a greater damaging effect on blood compared to left ventricular shunting.
• Balloon pump counter-pulsation resulted in the least amount of hemolysis, indicating minimal blood trauma.

Impact:

• Findings provide critical data for the design and selection of safer assisted circulation devices.
• Highlights the need for careful consideration of blood-device interactions to minimize complications.
• Informs clinical practice regarding the choice of circulatory support to reduce iatrogenic blood injury.
