Lightning injuries.

Lightning kills or injures thousands of people in the United States each year. Injuries are caused by the effects of electrical, thermal and mechanical energy, and a wide range of clinical results, involving multiple body systems, is possible. Important differences exist between lightning victims and patients injured by fire or by other forms of electricity. In lightning victims, successful resuscitation is highly likely, even among patients with conventional signs of brain death. With proper management, long-term physical and psychologic sequelae of lightning injury are rare.

Lightning injuries.

Lightning causes more deaths than any other weather phenomenon. It is an electrical current that will choose the shortest paths between the contact points of the human body and may involve vital structures in its pathway. Almost every organ system can be injured by the electrical current of lightning. A broad spectrum of complications resulting from damage to the various organ systems has been reported. The sequelae peculiar to this specific type injury will dictate the choice of therapy.

When lightning strikes. Pathophysiology and treatment of lightning injuries.

Lightning accidents are responsible for several hundred deaths and thousands of injuries each year in this country. Survivors sustain a variety of cardiac, neurologic, musculoskeletal, and dermatologic injuries. Eye and ear injuries are also occasionally noted. Education on how to minimize the possibility of such an accident is the best method of dealing with the problem. When prevention fails, prompt cardiopulmonary resuscitation and supportive treatment for the patient's particular injury are indicated.

Prevention and treatment of lightning injuries.

Lightning ranks first among natural disasters in terms of fatalities and property damage each year. If fortunate enough to survive, the victim of a lightning or electrical accident often presents with numerous complicated clinical manifestations. The astute nurse practitioner will be challenged to identify the immediate signs and symptoms of possible system disruption, and to institute the follow-up management necessary to prevent further complications. This article explores the nurse practitioner's role in the physical assessment of the client and the protocol for management and follow-up care. Case studies are presented to illustrate the various multisystem findings of clients struck either directly or indirectly by lightning. Environmental precautions to decrease the likelihood of lightning's harmful effects are also discussed. It is easier to prevent a lightning and/or electrical accident than to treat the victim.

Telephone-related lightning injury.

OBJECTIVE: To review reported telephone-related lightning injuries, outline the mechanisms of injury and suggest treatment strategies. DATA SOURCES: Cases notified to Telecom Australia and an extensive search of the literature. DATA SYNTHESIS: There is a dearth of literature on telephone-related lightning injury. Some reports note it in passing, others describe single incidents. Case reports from Australia provide detail sufficient for review, and the general principles which govern management of such injuries are presented. CONCLUSION: Telephone-related lightning injury is not rare. Practitioners should be aware of the uniqueness of lightning injury and the complexity of its assessment. A research program aimed at further elucidation of the detail of this injury is proceeding.

Telephone-mediated lightning injury: an Australian survey.

Each year in Australia, about 60 people report injuries attributable to lightning surges while using a telephone during nearby thunderstorms. This paper presents information about such incidents and describes a retrospective survey of more than 300 telephone users reporting injuries possibly attributable to lightning. Questionnaires yielded 132 usable responses, and the results were analysed to identify the extent and nature of the lightning injuries. These are compared with direct strike injuries. Three distinct telephone-mediated lightning strike syndromes are identified (statistically) among the victims.

[Myocardial damage following lightning injury].

In a 27-year-old woman, struck by lightning behind the left ear, the ECG showed signs of an acute posterior-lateral myocardial infarction after 1 h of unconsciousness and loss of memory. Her serum enzymes were increased as is typical of myocardial infarction, but the patient did not complain of cardiac symptoms. Besides clear signs of lightning injury, the patient showed a hemorrhage throughout the left breast and transient pericardial effusion was observed by echocardiography. In the course of two months, the ECG revealed a regression to unspecific ST-T-deviations and serum enzymes became normal. TI-201-myocardial-scintigraphy (SPECT), done six days and two months after lightning injury, excluded reversible and irreversible perfusion defects.

The physical effects of lightning injury.

Several thousand lightning-related injuries occur each year in the United States resulting in nearly 600 deaths. Most incidents involve individual victims; group lightning strikes are rare. Ten soldiers were simultaneously injured in a group lightning strike while on training maneuvers at Fort Benning. Georgia. No deaths or loss of consciousness occurred, although two of the soldiers had amnesia for the event. All of the soldiers were hospitalized and observed for potential lightning-related complications. Ninety percent of the soldiers had first-degree skin burns, and all had focal muscular tenderness. Seventy percent had transient ST segment elevation that resolved. Fifty percent developed creatinine kinase (muscular component) elevation, but none developed myoglobinuria or acute renal failure. No patient had creatinine kinase (myocardial component) elevation. Transient hypertension and tinnitus were noted in 40% and 20%, respectively. No compartment syndromes or ocular manifestations developed. All 10 soldiers recovered uneventfully and returned to full active duty.

Lightning injuries. A unique treatment challenge.

Care of victims of lightning injury is a unique challenge rarely encountered in most clinical practices. Victims may present without signs or symptoms or, conversely, may present in cardiac arrest. Many have chronic, debilitating sequelae. Physicians caring for these patients either in the field or in the emergency department should be prepared to institute aggressive management techniques. An understanding of lightning physics and injury patterns prevents costly and inappropriate diagnostic tests and treatment.

Acute polyneuropathy due to lightning injury.

The case of a 19 year old man struck by lightning is described. He sustained quadriplegia for several months and fully recovered. It is suggested that his weakness was due to extensive peripheral nerve damage. In addition, he displayed many well recognised medical complications of lightning injury including acute renal failure, rhabdomyolysis, respiratory distress syndrome, autonomic dysfunction, perforated ear drum, uveitis and cataract. The literature relating to the neurology of lightning strike is briefly reviewed.

Lightning injuries.

The physical properties of lightning are given, including a description of the different observed lightning forms. The wide variety of effects of lightning on humans is reviewed. In the prehospital care of those struck by lightning, emphasis is upon immediate resuscitation of those who appear unresponsive. Recommendations for emergency department evaluation, treatment, and disposition are given. Guidelines to prevent humans from being struck by lightning are discussed.

Cutaneous manifestations of lightning injury.

This report calls attention to a bizarre, almost pathognomonic, cutaneous feature of lightning injury. It has been variously described as "lightning prints," "arborescent" burns, or "feathering," and has long been neglected in the dermatologic literature. Its recognition may be lifesaving in the unaccompanied comatose patient and is important because even delayed resuscitation of lightning victims can be very successful.

Lightning injury: two case histories and a review of management.

Two cases of fatal lightning injury are described. Fixed dilated pupils should not be taken as an indicator of death after a lightning strike. Persons who fail to breath spontaneously within one minute of lightning shock should receive external cardiac massage and mouth-to-mouth resuscitation. Paralysis may persist as result of cerebral oedema or prolonged hypoxia-it is therefore suggested that adequate ventilation and metabolic balance should be maintained until recovery or death.

Lightning injury caused by discharges accompanying flashovers--a clinical and experimental study of death and survival.

During the 17 years preceding March 1985, 140 patients sustained lightning injuries caused by 44 thunderbolts. Fifty patients showed evidence of current flow through their bodies. These 50 victims were classified into two groups, the first consisting of 9 victims who showed rupture of their clothes or linear superficial dermal burns along their whole bodies from head to feet, indicating the occurrence of surface flashovers. The remaining 41 patients showed no evidence of this flash effect. It is noteworthy that in the first group 5 of the 9 survived, whereas in the second group only 6 among 41 survived. The result indicates that when a flashover occurs along the whole body, the probability of survival is higher than 50 per cent. The conditions which determine death or survival were investigated experimentally, imposing artificial lightning voltage impulses on rats and developing flashovers on them. The rats survived when the voltage drop caused by flashover occurred immediately after the peak point, and the current waveform exhibited a sharp peak. In contrast, the rats were killed when the voltage drop caused by flashover was delayed by more than 20 microseconds, and the current waveform showed a blunt cone shape. It has been concluded that a fast flashover appreciably diminishes the energy dissipation within the body and consequently results in survival.
