Superficial lightning injuries--their "fractal" shape and origin.

The origin of superficial lightning burns was studied. A recently developed mathematical model was invoked to identify fern-shaped burns as 'so-called' fractals. On the basis of this model and discharge experiments, we conclude that 'fractal burns' are caused by surface discharges of a positive polarity. The recognition of such burns can help to elucidate the type and mechanism of the lightning strike.

Lightning injury: management of a case with ten-day survival.

A boy, injured by lightning, had cardiopulmonary arrest. Following resuscitation and during the course of hospitalization, he developed further cardiac arrhythmia, cerebral edema, generalized seizures, and upper gastrointestinal bleeding. Despite efforts to combat these complications, the patient's condition deteriorated, and he died on the tenth day of hospitalization. The pathologic findings are described and the treatment discussed.

[Lightning injury of the ear].

Three cases of auricular fulguration are described and used as a basis for a review of physical characteristics and histopathologic consequences of lightning strikes. Cases are presented and discussed in relation to these fundamental and experimental data.

Cardiopulmonary arrest secondary to lightning injury in a pregnant woman.

A young woman who was seven months pregnant was struck by lightning, resulting in cardiopulmonary arrest. Bystander CPR was begun at the scene. Vital signs were restored by the time the rescue squad arrived. The patient was comatose on arrival in the emergency department and fetal death was apparent. The patient's neurological status improved markedly, with a small residual motor deficit.

Lightning and electrical injuries.

Lightning and electrical injuries are similar in that both produce immediate tissue injury from burn and trauma induced by fall and both can arrest the heart and respiratory center. Immediate support of circulation and respiration is life-saving. Subsequently the nervous system may show signs of injury, and seizures, cerebral edema, and muscle and nerve lesions should be handled as the indications arise. Prevention of the injury is more effective than any postinjury treatment. Outdoors hikers and campers must take shelter to minimize their exposure; indoors properly installed equipment and attention to the relation of the equipment user to the electrical ground are the key elements in avoiding electrocution.

Neurorehabilitation of lightning and electrical injuries.

Lightning and electrical (L/E) injuries can be among the most dramatic of all events that damage the nervous system. The three major classes of neurologic sequelae that require the expertise of the neurorehabilitationist are: (1) cerebral disorders, either global or focal; (2) neuropsychologic sequelae; and (3) spinal cord injury. Neurorehabilitation management necessary for each of these three areas will be discussed. From the viewpoint of the neurorehabilitationist, therapy principles are the same for L/E trauma as for other more common forms of injury. The goal is to maximize the functional return given the specific impairment.

Electrical injuries and lightning.

Prolonged cardiopulmonary resuscitation is key to the resuscitation of lightning strike victims. Multiple accounts exist of successful revival of victims thought to be "dead" or in patients who have what is often believed to be unresuscitatable cardiac dysrhythmia. Victims of lightning injury may, in addition to their electrical injury, have secondary injuries that require expedient care if significant morbidity is to be avoided. They should be treated as any victim of trauma, that is, with a complete and thorough evaluation including hospitalization if warranted. In the absence of a cardiac arrest or serious secondary injury, care for the lightning strike victim is generally supportive in nature.

Neuropathology of lightning-strike injuries.

When a person is struck by lightning a spectrum of neurologic damage can result. Approximately one third of the strikes prove to be fatal. The possibility of damage to the CNS relates to the type of lightning injury (direct strike, stride potential, or side flash), the intensity and duration of the current, the pathway of the current within the body, and secondary injuries to brain either from cardiac arrest and hypoxia or from physical trauma. Direct strikes to the head have a high degree of fatality and often result in petechiae or larger brain hemorrhages. Although there may be some predilection for the petechiae to occur in the brainstem, the larger hemorrhages may be particularly located near the pathway of the electrical current and result from direct damage to brain vasculature. Enlarged perivascular spaces seen histologically are relatively subtle; they have been attributed to the effects of gas bubbles from electrolysis, heat formation, or both. Small vessel thrombi and neuronal changes may be present nearby. Some brain tissue softening and edema may be direct effects of passage of current. Often, however, hypoxic encephalopathy and cerebral edema occur following cardiopulmonary arrest when the passage of the current through the body presumably generates cardiac arrhythmias. Considerably less is known about the spinal cord injuries in lightning strike, although one detailed recent study suggests that demyelination may be an underlying mechanism. Similarly, myelin damage appears to be a feature of electrical and possibly lightning injury to the peripheral nervous system.
