By electrical injury is understood the defeat of the whole organism or its individual parts as a result of the passage of an electric current. The degree of damage is directly proportional to the time the current passes through the body. The skin has a very large electrical resistance, being like an insulator. All other tissues are an aqueous solution of various salts that transmit current well. As a result of heat generation in the tissues, an electric burn of various degrees occurs: from redness, blistering, necrosis, up to charring of certain parts of the body. Since the skin has an especially strong resistance to the incoming and outgoing current, its burn is the most severe.
In case of an electric trauma, the inner ear is most affected, a sharp expansion of the blood vessels of the inner ear occurs with hemorrhages in various parts of the ear labyrinth, protein coagulation in the peri-and endolymph. The vestibular apparatus is less frequently affected by the auditory. In the long term after an injury, fibrous connective and bone tissue grows in the ear maze. After 1-3 months, degenerative changes occur in the cortic organ.
A burn of the auricles is noted up to carbonization in combination with hemorrhage in the eardrum, tympanic cavity, degeneration of the neuroepithelium of the spiral organ and spiral ganglion. Auditory function suffers more, even deafness, than vestibular, as the inter-labyrinth asymmetry is gradually compensated. Tinnitus, labyrinthine nystagmus, Horner's syndrome, taste perversion are noted. Of the common phenomena of trauma, fainting, respiratory arrest, shock, cramps, and paralysis are observed. There are cases when deafness and dumbness immediately arose from a lightning strike. There may be “ciaee iieiee” on the skin, eia? Uea aea o? Anoeia ei? E? Aeoiaaoi-ao? Iai oaaoa eee a? Aaiaeaiuo e?

The victim is immediately exempted from electrical wires using improvised insulating materials (rubber coat, dry stick, wooden board, dry newspaper, rubber mat). The injured person is taken out of the danger zone and breathed “from mouth to nose” or “from mouth to mouth”, iai? Yiie ianna? na? aoa. Apply respiratory stimulants (oxygen, lobelin), cardiac drugs. In severe cases, bloodletting, blood transfusion, the introduction of blood substitutes, anti-shock fluids and spinal puncture are required.
When treating ear burns, conservative methods are followed, since they are prone to self-healing. An aseptic dressing is applied to the damaged area and treated according to the principles of burn therapy. Persistent disfigurement of shells is eliminated by plastic surgery.
The injured should be hospitalized, since even in the absence of complaints, symptoms may subsequently appear from the central nervous system and circulatory organs. One of the main measures for the prevention of electrical injury is the strict observance of safety regulations.
The doctor of the unit for any ear injury provides first aid to the victim and sends him to the hospital. In part, under the conditions, it is allowed to treat patients with small, non-penetrating lesions of the skin of the auricle, burns and frostbite of the I-II degree with a completely satisfactory general condition. During evacuation, the torn auricle must either be bandaged to the victim’s head or placed in a double plastic bag with ice or snow.
Survey of servicemen at testimony is carried out according to article 81 of the order of the Ministry of Defense of the Russian Federation N 315 1995

- EAR INJURY, FOREIGN BODY OF THE EAR
In case of an external ear injury, first aid is similar to first aid for injuries. Damage to the eardrum can occur during explosions, diving, during diving operations. The rupture of the membrane is accompanied by pain, hearing loss, minor bleeding from the ear. First aid: - insert a sterile cotton swab into the external auditory meatus; - put on the ear
- Electrical injury
Non-observance of industrial safety rules, inept or careless handling of electricity in everyday life leads to accidents - electrical injuries. A type of electrical injury is also a lightning strike - the discharge of atmospheric electricity. The effects of electric shock are minor (local changes in the skin, local pain, lethargy,
- Electrical injury to the nervous system
Clinic. The impact on a person of technical or atmospheric (lightning) electricity, the strength of which reaches 0.025-0.05 A, may be accompanied by the onset of symptoms of electrical trauma to the nervous system. Their severity depends not only on the strength of the current, but also on the state of the organism at the time of its impact. Electric trauma is harder for people with thin wet skin, tired, with disorders
- Electrical injury
Electrical injury occurs when an electric current is applied to the human body, as well as atmospheric electricity - lightning. Under the influence of electric current, local and general changes occur in the body. Local tissue changes during electrical injury - “current signs” - have a tree-like shape. They are thermal burns of varying severity - from minor to
- Electrical injury. Drowning. Asphyxia
1. Patient A., 56 years old, was delivered to the clinic with a diagnosis of electrical injury received in a domestic environment. At the scene, he lost consciousness, others carried out resuscitation (mouth-to-mouth ventilation, indirect heart massage). Joint venture employees intubated the trachea and resuscitation was continued. Necessary: to appoint an additional examination,
- Electrical safety Risk of electrical injury
The use of medical electrical equipment entails the risk of electrical injury for both the patient and medical personnel. Therefore, the anesthesiologist must have a basic understanding of electrical safety. Contact of the human body with two conductive objects (conductors), between which there is a potential difference, leads to the closure of the electrical circuit (circuit)

- ELECTRIC INJURY. PATHOGENESIS, CLINIC
An electric injury is a lesion that occurs under the influence of an electric current and is the sum of the direct consequences of the passage of an electric current through the tissues of the body and a burn with a flame of a volt arc. Sources of electric current that affects a person can be domestic and industrial electrical installations, atmospheric electricity. Damage occurs as with
- Electrical injury
Electrical injury — damage caused by exposure to high voltage electric current. The most common causes are electrical injuries, contact of a child with exposed electrical wires, and the introduction of metal objects into sockets. The following sources of electrical energy can cause damage: - sources of direct and alternating current (high-voltage lines
- Electrical injuries
By electrical injury is understood damage resulting from the action of technical or atmospheric electricity. A feature of electric shock is that damage occurs both at the point of contact and on the path of the passage of current and its output. Sometimes health problems and death occur without visible damage. However, sometimes they arise from a distance. Electric Energy
- Electrical injury
Electrotrauma - electric shock, accompanied by damage to surface tissues and a possible violation of the activity of organs and systems up to the state of clinical death. The cause of electric shock is as a deliberate unconscious, especially in young children, touching current-carrying elements (wires, contacts, power sockets, etc.),
- ELECTRIC INJURY IN DOGS AND CATS
Electrical injury in dogs and cats occurs when they bite the wire of an electrical device connected to the network. From a sudden electric shock, the animal screams, bounces. A tissue defect and traces of tissue burn are formed on the gums and lips - an electrometric device, which at the first moment has a white-brown color. A feature of electric burns is a deep tissue lesion. The size of the damage depends on
