Abstract
Electricity is a potentially very dangerous commodity. Community safeguards, however, result in remarkably efficient control of this hazard. Mortality figures appear to be small and constant. No satisfactory morbidity figures are available with regard to general and neurological complications in non-fatal cases. Study of relevant features of such electrical phenomena as voltage level, resistance factors, current pathway, current diffusion and grounding reveals many difficulties in reconstruction of the sequence of events involved in these injuries. These features underline our frequent inability to understand the mechanisms of initiation of unconsciousness and even of differentiation between death by cardiac arrest and death by respiratory paralysis. Fourteen cases of electrical injury with a variety of neurological complications and sequelae are discussed, and the findings in these cases are compared with those of other observers. An attempt is made to present a comprehensive picture of immediate, secondary and late neurological effects, and to illustrate some of the pathological findings in electrocution material.
