Backgrounds: Good documentation of electrical injuries at the time of presentation is very important for emergency management, so this study was designed to investigate the clinical characteristics and the outcome of the patient with electrical injury. Through the clinical review of electrical injuried patients, We would like to know if any electrical injury actually causes patients to develop the cardiovascular injuries and musculoskeletal injuries to some extent, and easily find whether the patient’s underlying tissue is damaged by the electrical injury.
Method: A review of 26 cases of electrical injuries admitted to Chosun University Hospital via the emergency department over the period of 3 year from 1998 to 2000 was conducted.
Results: There were 11 patient’s with high-voltage injuries and 15 patients with low-voltage injuries. The most common type of injury was contact burn which had both entry and exit. The majorities of contact burn patients had minor burns of total body surface. Myoglobinuria was noted in a patient, but didn’t develop acute renal failure. In the high-voltage group, 9 patients had false positive results in urine occult test. These patients had elevated muscular enzyme level as like LDH(lactate dehydrogenase), CPK(creatine phosphokinase), AST (aspartate aminotransferase). In the low-voltage group, a patient developed ventricular fibrillation. The complications of electrical injury were observed, which were peripheral neuropathy in 2 cases, compartment syndrome in 2 cases, loss of consciousness in 2 cases, and corneal injury 2 cases. Compartment syndrome occurred as a result of vascular ischemia and muscle edema.
Conclusion: Urine occult test is useful for evaluation of severity of tissue injury evaluated in high-voltage electrical injuried patients. False positive result in urine occult test prevents acute renal failure by attempting initial fluid therapy.
