Lightning Ground Current Injury: A Subtle Shocker

Lightning injury: a review.

Lightning is an uncommon but potentially devastating cause of injury in patients presenting to burn centers. These injuries feature unusual symptoms, high mortality, and significant long-term morbidity. This paper will review the epidemiology, physics, clinical presentation, management principles, and prevention of lightning injuries.

Electromagnetic Field Due to Lightning Strikes to Mountainous Ground

The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...

Lightning injury with survival.

CT of lightning injury.

A 20-year-old man was on a fishing trip in a boat on Delaware Bay. At one point during an ensuing storm, he rai sed his head above the rigging and was immediately stru ck by a lightning bolt that also momentaril y stunned his companions. They recovered to find him unconscious on th e bottom of the boat with blood-tinged fluid emanating from his left ear . After a brief examination at a nearby h...

Biophysical injury mechanisms associated with lightning injury.

The passage of damaging quantities of electrical current through the body can produce tissue injury through multiple distinct biophysical energy transduction mechanisms. These mechanisms include the direct action of direct electrical forces on proteins, membranes and other biomolecular structures, as well as the indirect action mediated by the generation of heat. Adding to this complexity are t...
