Experience of urgent reconstruction of electrical injuries.

Although there have been great advances in the treatment of electrical injuries in the last 20 years, the extremity loss ratio in electrical injuries remains at an unacceptably high level. The primary reason for this is the progressive tissue necrosis and enlargement of the necrosis in the wound. The goal in this study is to examine possible ways to break the necrotic malignancy circle and save the form and function of damaged extremities. As a result of systematic experimental and clinical research, a comprehensive urgent reconstruction alternative for electrical injuries has been proposed. The alternative includes the following principles: debriding the wound as early as possible after injury; preserving as much as possible the vital tissue structures, such as nerve, vessels, joints, tendons, and bone, even when they have undergone devitalization or local necrosis; transplanting these vital tissues during the first surgery if the functional reconstruction requires; nourishing the wound bed by covering with tissue flaps that have rich blood supply; improving flap survival by continuous irrigations with a compound medicine beneath the flaps for a 24- to 72-hour period after surgery; providing general treatment with vasoactive agents and antibiotics. This paper summarizes our experience of using this method in the treatment of 105 electrical injury patients (a total of 309 wounds) in the time period from 1 January 1986 to 31 December 1996. Satisfying results were obtained, with the extremity loss ratio decreasing to 7% as compared to 41.5% during the 10 years preceding 1984 at the same hospital. Thus, the urgent comprehensive reconstruction alternative presented here is an effective and workable method to manage electrical injuries.

Outcome and Treatment of Electrical Injury with Immediate Median and Ulnar Nerve Palsy at the Wrist

Electrical injury to the upper extremity with immediate median and ulnar nerve palsy at the wrist is uncommon but devastating. When it does occur, the immediate clinical questions are (1) will the nerves recover, and (2) should the carpal tunnel and Guyon's canal be released? Our review of the literature did not answer these two questions. Therefore, we reviewed our experience with such patients and surveyed approximately 10% of the physician members of the American Burn Association. We reviewed approximately 80 patients with electrical injuries treated between January 1983 and September 1988, and found 5 patients (8 extremities) who did not require amputation and who manifested immediate palsy of the median and ulnar nerves at the wrist. The questionnaire was returned by 83% of those contacted. We concluded that such nerve palsies can recover to a significant degree and that a majority of surgeons would release the carpal tunnel and Guyon's canal, expecting improved recovery. Although it is still not proven whether decompression is beneficial, we will continue to decompress the carpal tunnel and Guyon's canal in such circumstances.
