First aid at blow by current

The blow by current causes an electric trauma – the special type of an injury different from all others. Most often current electricians, owing to the professional activity, and children, owing to the curiosity and insufficiency of attention are exposed to blow from adults.

The greatest danger at blow by current is made by its impact on a cardiac muscle. It is known that reduction of a cardiac muscle happens under the influence of the electricity of weak power produced by an organism. The powerful charge from the outside causes failure in cardiac performance, arrhythmia, fibrillation of auricles and their paralysis then there comes the lethal outcome can be result of what.

Besides, the electric trauma causes a burn which weight can be truly estimated not at once as electroburns are specific – they extend not superficially, as in case of defeat by fire, and to the considerable depth, striking hypodermic fatty tissue, muscles, vessels, nerve terminations and even bones. At the same time external manifestations of an elekroozhog are very small.

One more injuring factor is in what at blow by current of significant force of the person discards, i.e. the electric trauma quite often is followed also by a mechanical injury – fractures of extremities, bruises, stretchings and ruptures of soft tissues.

In view of all listed factors, becomes clear that an electric trauma – very serious type of damages of an organism to estimate extent of damages to the nonspecialist very difficult, at the same time there is a direct threat of life of the victim. Therefore, within first-aid treatment at blow by current, it is necessary to cause as soon as possible on the scene of the doctor or crew of acute management. Assessment of gravity of an electric trauma and its treatment occur in a hospital.

Pre-medical measures of first aid at blow by current

Before starting directly assistance, it is necessary to estimate a situation. The victim can be under the influence of a current and touch it can be unsafe.

It is desirable to disconnect immediately the electric power source which became the injury reason. If such opportunity is absent, the source (as a rule, it is a high-voltage wire) should be removed from the victim by means of the dry subject having low conductivity. It can be a leaf of a cardboard, a dry branch of a tree, a plastic stick. Only after that it is possible to start actions for assistance.

Algorithm of actions of the rescuer giving first aid at blow by current, following:

1. It is necessary to be convinced available breath and cordial activity. If pulse on a carotid artery is absent, and the person does not breathe, it is necessary to begin immediately cardiopulmonary resuscitation (breath of companies - in - a mouth, a mouth - in - a nose, an indirect cardiac massage);
2. If the victim breathes, it is necessary to lay him so that the head was placed below legs (legs should be raised slightly). It is a necessary antishock measure;
3. The body parts damaged as a result of a burn or the secondary injury got when falling need to be closed pure fabric not to allow hit of an infection in them. Best of all sterile bandage or a gauze will be suitable for this purpose if they are absent – a pure linen towel, a sheet, a shirt. It is impossible to use fleecy fabrics, for example cotton wool, terry towels or woolen blankets;
4. Further measures consist in maintenance of life activity of the victim before arrival of ambulance. In cold season it is necessary to watch that there was no frostbite, in roast – an overheat.

If the victim is in consciousness, it must be kept in mind that the electric trauma can cause damages to a nervous system including a brain, and also what is not obligatory all symptoms of damage are shown at once.

Not to do without medical assistance

Feature of damages from blow by current is their depth and impact practically on all fabrics and bodies located on the course of an electric loop. That is why, even if at first sight it seems that everything was, it is impossible to refuse hospitalization and medical examination at all. Even if the victim considers that first-aid treatment at blow by current was sufficient, rescuers have to insist on immediate visit of the doctor. Otherwise it is not excluded that the bodies and fabrics which underwent an electric trauma will work with gradually accruing disturbances that can lead of the person who received to death the nonlethal blow by current, several days later after an injury would seem.
