Neurological manifestations of electrical trauma.
Some degree of neurological impairment is often found in patients following electrical injury. A wide range of neurological impairments can occur including peripheral neuropathies, chronic pain syndromes, brain injury and rarely severe paralytic syndromes. Outcome is difficult to accurately predict. The symptoms can present immediately or be delayed in onset. They can also be temporary, permanent or get progressively worse with time. The neurological impairment resulting from the current often comprises a substantial proportion of the morbidity associated with such injuries. It is known that electrical current can cause nerve injury, however, the primary etiology of such damage is yet to be elucidated. An unusual case of transient paralysis after high voltage burn associated with severe hypokalemia provides unique insight into a potential mechanism for nerve injury following electrical trauma.
