Early vascular grafting to prevent upper extremity necrosis after electrical burns. Commentary on indications for surgery.

Early vascular grafting is the only effective form of treatment for electrical burns of the wrist which are severe enough to impair blood flow to the hand. Failure to appreciate the significance of early changes in blood flow and to take prompt appropriate action may result in the irreversible loss of blood supply and subsequent amputation. This report analyses the problems encountered in six patients where the early signs of impaired blood flow were not appreciated and amputations were subsequently required.
