Summary
Improved filter technology can remove lipids from blood during surgery. This study advocates for fat removal filters in surgical suction blood to prevent fat emboli and associated ischemic brain injury.
Area of Science:
- Biomedical Engineering
- Cardiovascular Surgery
- Blood Filtration
Background:
- Lipids, including triglycerides, glycerol, and free fatty acids, are a focus during surgery.
- Fat emboli in brain, lung, and kidney tissue are linked to post-cardiac surgery ischemic injury.
- Surgical wound suction blood during cardiac surgery contains numerous microemboli.
Purpose of the Study:
- To evaluate the potential of improved filter technology for removing specific blood substances like lipids.
- To assess the efficacy of fat removal filters in surgical suction blood during cardiac procedures.
Main Methods:
- Investigated improved filter technology for lipid removal from blood.
- Analyzed surgical wound suction blood from cardiac surgery for microemboli content.
Main Results:
- Fat emboli are observed in brain, lung, and kidney tissue post-cardiac surgery.
- Lung tissue and leucocytes are particularly susceptible to free fatty acid damage.
- Surgical suction blood contains significant amounts of microemboli.
Conclusions:
- Fat filtration during cardiac surgery is a potential therapeutic strategy.
- Utilizing fat removal filters for surgical wound suction blood is recommended as a first step.
