Symptoms.—When an individual is struck by lightning, he falls uncon- scious immediately due to syncope or concussion, and dies at once from paralysis of the cardiac and respiratory centres or subsequently from the effects of burns and lacerations after some days or even weeks. In non- fatal cases the individual complains of giddiness, ringing in the ears and headache. These symptoms pass off very soon or hysteria and nervousness may supervene, when the lightning discharge is very slight, though in severe shock the individual may suffer from affections of the eyes, including con- junctivitis, clouding of the cornea, cataract and retinal haemorrhage or detachment, and later from loss of memory, ansesthesia, paralysis, tetanic convulsions, delirium, blindness, deafness or dumbness. The lesions produced by lightning stroke are varied, and may consist of ecchymoses, contusions, lacerations, -wounds of almost any variety, simple, compound or comminuted fractures of bones and burns varying in depth and extent. In addition to the singeing of the hair, blisters, fissures and even charring caused by burns, reddish-brown arborescent markings are often seen on the surface of the skin. These markings are superficial burns producing mere erythema of the skin, which indicates the paths taken by the branching nature of the discharge. Fig. 73.—Burns caused by Lightning.
