Open wound management, until the wound is considered suitable for reconstruction or until it has healed by second intention, has been the treatment of choice for centuries (Pavletic, 2010). The aim of wound healing is to promote rapid wound closure and prevent excess scar formation. Wound healing stimulated an optimum microenvironment for successful reconstruction can be created by employing modern method such as electrical stimulation (Shakespeare, 2001).The wounds were treated with electrical stimulation that delivered positive / negative current with the help of electrical stimulator. The flaps performed in the present study were single pedicle and bipedicle advancement flaps, flank and elbow rotational flap, transposition flap and caudal superficial epigastric flap. The flaps were selected based on the location and site of the wound. Subjective evaluation of wound healing based on the physical observations such as colour, odour and presence of exudates for recipient wound bed and skin flap respectively were performed. Clinical photography, wound planimetry studies were evaluated. Additionally, hematological, bacteriological, biochemical, and histopathological evaluation were done for the recipient wound bed and skin flap. A subjective analysis of vascularity of the donor site was performed through Colour Flow Doppler Ultrasonography. From the results of the present study electrical stimulation improved the survival rate and blood flow of skin flaps through enhanced capillary growth, increased wound strength, hastened wound closure and better protected the granulated tissue and wound against rupture and infection.
