Fatal electrocution a 10-year retrospective study in the Lisbon Area

Abstract

Electric current can determinate a fatal outcome – electrocution – which is a relatively unique death. The aim of our 10-year retrospective study is to characterize the trend of deaths by electrocution occurred within the Lisbon Area. Database of the Forensic Pathology Department, between 1999 and 2008, was scanned for fatal electrocution, and several medico-legal variables were analysed. Of the 25 victims, only one was female, 60% were between 18 and 34 years-old and 64% had professions related to construction and electricity industries. Death occurred on place in 76%, the passage of current was direct in 76%, related to low voltage in 52%, and in 68% was the result of a labour accident. Electrical burns were found in 84% and thermal burns in about 50%. Signs of passage of electric current were identified in about 50%. Ethanol and cocaine were present in 2 separated cases. Death was caused directly by the passage of electric current in 84%, of which 24% were associated with blunt force trauma or thermal burns. Results are quite similar to those of other studies, and underscore the importance of a better understanding of the phenomenon in order to prevent this kind of fatal incidents
