And we're back! After a brief festive season hiatus, QotW returns...
Did you do the last question of the week?
Keraunoparalysis typically occurs in the LE's and is characterized by transient paralysis associated with mottle, cool, blue, and pulseless extremities. It results from sympathetic instability and vascular spasm. These resolve over minutes to hours. Asystole is the most common cause of death from lightning strike.
Usually the automaticity of the heart will resume spontaneous activity, often the respiratory arrest persists and may result in dysrhythmias secondary to the hypoxia, not the strike. "Flashover" describes the rapid movement of current over the skin rather than through the body leaving an "arborescent" (fern-like) pattern on the skin.
Florida, where I trained, is the area with the most lightning strikes yearly in the world. We would see one or two a week during the summer months.
