Laser induced clot formation in blood treated by EDTA
Author(s) Balsam M. Mirdan

Patients under systemic (ethylenediaminetetraacetic acid) EDTA are at risk of hemorrhage for any accidental trauma even the superficial ones. This research is a trial to use 980 nm wavelength laser light to provide coagulation for such patients in a local region without collateral thermal damage. Material and Method: 980 nm Diode laser operating in a continuous mode (CW) was incident on human blood treated with EDTA inDurhamtubes. The used parameters were (2.25, 3, 3.75 and 6.75) W output power for variable exposure times (1, 3, 9 and 27) s. Results: A homogenous clot was performed at 4327.84 J/cm2 deposited energy density with the absence of any thermal stress in the blood. Conclusion: 980 nm laser wavelength provides a local photochemical bond break of the anticoagulant enhancing blood coagulation for medically compromised patients.
