Surgical cautery revisited.
A new hemostatic scalpel has been developed to control bleeding between the cut edges of wound tissue. The scalpel blade resembles conventional scalpel blades, except that it can be heated and its temperature controlled within narrow limits. Cutting is accomplished by the blade's sharp edges, and hemostasis results from the direct transfer of heat from the blade to the tissue. This experimental study has demonstrated that the hemostatic effect of the scalpel is associated with damage to the tissue's defenses against infection and impaired wound healing.
