Summary
Bowl autotransfusion devices remove fat from shed blood but may leave particles. If fat is visible, filter the blood with a leukocyte removal filter before reinfusion to ensure patient safety.
Area of Science:
- Cardiovascular Surgery
- Transfusion Medicine
- Biomedical Engineering
Background:
- Autotransfusion is a common practice to reinfuse a patient's own blood during surgery.
- Bowl-based autotransfusion devices are effective in reducing fat content in shed blood.
- However, complete elimination of fat particles remains a challenge.
Purpose of the Study:
- To evaluate the efficacy of bowl-based autotransfusion in fat removal.
- To determine the necessity and method for managing residual fat in processed shed blood.
Main Methods:
- Analysis of shed blood processed through bowl-based autotransfusion devices.
- Visual inspection of processed blood for the presence of fat particles.
- Assessment of the impact of leukocyte removal filtration on fat particle clearance.
Main Results:
- Bowl-based autotransfusion significantly reduces, but does not eliminate, fat particles in shed blood.
- Visible fat on the surface of processed blood indicates incomplete fat removal.
- Leukocyte removal filters effectively remove residual fat particles.
Conclusions:
- Residual fat particles in autotransfused blood can be managed by filtration.
- Leukocyte removal filters are recommended for processing shed blood with visible fat before retransfusion.
- This practice enhances the safety of autotransfusion procedures.
