Current Pathways in High-Voltage Injuries

Studies were done in the hog with limb-to-limb contacts at potentials up to 2000 V. The current density in nerve, vessels, muscle, bone, fat, lungs, heart, kidney, liver, intestines, and spinal cord were determined. The current densities in the leg are largest in nerve and artery, followed by muscle, fat, and bone. The temperature was greatest in fat and nerve. With forelimb-to-hindlimb current application, the current densities were largest in the back region. The spinal cord current density was approximately twice the average cross-sectional value.
