Electronic antihemocoagulation

Area of Science:

• Biophysics
• Hematology
• Biomedical Engineering

Background:

• All cells and body surfaces possess electrical charges, influenced by their environment.
• Blood particles are predominantly negatively charged.
• Vascular trauma can alter surface charges, leading to thrombosis.

Purpose of the Study:

• To investigate the effect of electrical current conduction by blood on clotting.
• To determine the stage in the clotting sequence where electrical effects occur.

Main Methods:

• Application of electrical currents to simulate wound conditions.
• Laboratory experiments using oppositely charged electrodes in blood.
• Development of specialized bridge circuits and test cells.
• Analysis of saline compartments for component migration.

Main Results:

• Electrical currents can extend clotting by over 400%.
• Negative currents inhibit clotting, causing prolonged oozing.
• Positive currents accelerate clotting.
• Leukocytes migrate towards negative electrodes, suggesting polarity changes.

Conclusions:

• Electrical current manipulation offers a novel method to control blood coagulation.
• Low currents (below 1 mA/cm²) do not cause significant blood trauma.
• The findings suggest potential applications in wound healing and thrombosis prevention.
