Early vascular grafting to prevent upper extremity necrosis after electrical burns: II. Experience with wound infection management.

Since May 1972, vein grafts have been used to restore circulation in electrical injuries of the upper extremity when the wrist has been the centre of electrical injury associated with obstructed blood supply. Saphenous vein grafts were used in fifteen limbs in fourteen patients where electrical injuries at the wrist threatened complete loss of the hand. Ten of the hands were free of necrosis with motion basically recovered. The other four cases (five limbs) failed in operation for various reasons, resulting in forearm amputations. Clinical practice showed that successful operations depend upon whether secondary infection is effectively controlled, particularly in those who were brought to the hospital late with wound infection and gangrene of the fingers. This paper reviews the measures for controlling postoperative infections in vascular grafting to restore blood flow at the wrist, and the clinical experience gained in treating these patients (six injured limbs of six cases), and preventing amputation. We hope the method could be improved and its use broadened.
