ELECTRICAL STIMULATION can help speed wound healing by increasing capillary density and perfusion, improving wound oxygenation, and encouraging granulation and fibroblast activity. Several manufacturers make the high-voltage pulsed current simulator used for this therapy.
Electrical stimulation can be applied in one of two ways. For the first method, one electrode (positive or negative polarity) is applied to sterile, conductive material, such as saline-moistened gauze, placed in the wound. The conductive surface of the other electrode is applied nearby on intact dry skin.
The second method involves positioning the conductive surfaces of two electrodes with the same polarity on intact dry skin on opposite borders of the wound, straddling the wound. A third electrode with the opposite polarity is placed nearby on intact dry skin.
In both methods, the pulse frequency is set to 100 pulses/second and the voltage ...
