Electric Shock - Conduction of Current To and Through the Human Body

image

Understanding how electric current reaches and travels through the body can help us understand how and why specific accidents might occur and what medical and surgical problems may be expected.

This article, published by Open Access Journal of Plastic Surgery does an amazing job. It was written by Raymond M. Fish and Leslie A. Geddes with the objective of explaining the ways in which electric current is conducted to and through the human body, and how this influences the nature of injuries.

Part A first reviews electrical and pathophysiological principles. There are discussions of how electric current is conducted through the body via air, water, earth, and man-made conductive materials. There are discussions of skin resistance (impedance), internal body resistance, current path through the body, the let-go phenomenon, skin breakdown, electrical stimulation of skeletal muscles and nerves, cardiac dysrhythmias and arrest, and electric shock drowning.

Part B considers specific types of accidents. It discusses a number of clinically relevant examples of accident mechanisms and their medical effects. Topics related to high-voltage burns include ground faults, ground potential gradient, step and touch potentials, arcs, and lightning.
