title: The use of the argon laser-assisted quartz scalpel for burn wound excision to fascia.
abstract: We have developed a new method for coupling the hemostatic capabilities of argon laser light with the mechanical advantages of a sharpened quartz blade using fiberoptics. Using the new laser-assisted scalpel, a series of symmetrical skin excisions was done in 20- to 30-kg pigs on one side and with electrosurgery on the other. The laser scalpel was superior in its hemostatic properties (p less than 0.01) with no statistically significant difference in surgical speed. Take of split-thickness skin grafts was 90% in beds excised with either the laser or the electrosurgical device. Histologic sections showed less tissue damage with the laser-assisted scalpel than with electrocautery.
