LOCAL DEFECTS AT ELECTRIC INJURY. ELECTRICAL BURNS

There are the following types of local lesions in electric shock:

The clinic of electric burns has significant differences from the thermal ones. The main feature is extensive damage to deep tissue with a relatively limited superficial lesion. Vessels, as the main conductors of the current are primarily affected by the current. Spasm and subsequent thrombosis leads to progressive necrosis. The external manifestations of electric burns are called "signs of current", which have the form a.) Scab - its color can be from whitish-gray to black (at the point of current input); b.) cut or stab wounds, abrasions (at the place of the current output).
At high voltages, the signs of current at the "outlet" may be similar to a gunshot wound.

Due to the great depth of damage, the rejection of dead tissues is delayed to 5-7 weeks. Therefore, the treatment of electric burns is a complex problem and requires, as a rule, as a demarcation line is formed, a series of necroectomy is performed, followed by plastic closure of the resulting defect.

LOCAL DEFECTS AT ELECTRIC INJURY. ELECTRICAL BURNS

  1. FIRST AID FOR ELECTRIC INJURY
    First aid for the defeat of electricity should be immediately, at the scene. First of all, it is necessary to release the victim from the action of electric current, since, due to loss of consciousness or convulsive contraction of muscles, he often cannot independently detach himself from the wire. It is important to remember about the danger of electric shock of the rescuer. Necessary if this
  2. First aid for electrical injuries
    Damage caused by an electric current or by lightning (a discharge of atmospheric electricity) is called an electric shock. Electratrauma causes local and general disorders in the body. Local changes are manifested by burns of tissue at the points of entry and exit of electric current, often very deep, of 3-4 degrees of weight. Common phenomena - convulsive muscle contractions, loss of consciousness, depression
  3. Percutaneous coronary interventions in the presence of bends in the coronary arteries, mouth lesions, calcified lesions, long lesions
    Percutaneous coronary interventions in the presence of bends in the bed of the coronary arteries, lesions of the mouth, calcified lesions, long
  4. Percutaneous coronary interventions for single discrete lesions of the coronary arteries, diffuse stenoses, multi-vascular lesions in IHD
    Percutaneous coronary interventions for single discrete lesions of the coronary arteries, diffuse stenoses, multi-vascular lesions with
  5. RENDERING FIRST MEDICAL ASSISTANCE WITH ELECTRIC INJURY, DECOMPOSITION, HEAT AND SOLAR IMPACT
    When exposed to electric current, local and general changes in the body occur. Local changes are characterized by the emergence of so-called electro-burns in the form of yellowish-brown or whitish spots. General changes are associated with the inhibitory effect of electric current on the central nervous, cardiovascular and respiratory systems. This may cause loss of consciousness, convulsions,
  6. Emergency and intensive care for electric shock, drowning and mechanical asphyxia
    1. The severity and outcome of electric shock depend on internal and external factors: 1) Fatigue 2) Alcohol intoxication 3) Chronic diseases 4) Thyroid overproduction 5) Overheating and excessive sweating Answer: a) correct 2,3,5; b) correctly 1,2,4; c) correctly 3,4,5; d) everything is correct. 2. The severity and outcome of electric shock depends on the loop of its passage. Most
  7. Local anesthesia by A. V. Vishnevsky during a cesarean section
    Until 1970, in our country, local anesthesia according to AV Vishnevsky was widely used for cesarean section, but with the improvement of general and spinal anesthesia this method was unreasonably forgotten, although sometimes there are situations in which other methods of anesthesia are contraindicated. The advantage of local anesthesia is safety for the mother and harmlessness for
  8. Variants of local and general reactions in infections
    In contrast to the extensive molecular-biological and biochemical diversity of infectious agents, the number of variants of tissue reactions to these agents is very small. Many pathogenic viruses, microbes and larger parasites cause identical microscopic changes in tissues, and only a few processes have features of etiological specificity. Purulent inflammation. It is characterized
  9. Percutaneous coronary interventions for multi-vascular lesion in ischemic heart disease
    One of the debatable problems of modern interventional cardiology is the issue of conducting multi-vascular angioplasty in patients with advanced coronary atherosclerosis. The solution of this issue requires the analysis of many factors: the definition of a multi-vascular lesion, the possibility and expediency of carrying out a complete and incomplete myocardial revascularization, the analysis of long-term results
  10. Percutaneous coronary interventions for single-vessel lesion in ischemic heart disease and single discrete stenoses
    Since the first coronary angioplasty was performed, the main coronary angiographic indications for this intervention have been determined. Single lethal proximal hemodynamically significant discrete non-calcified stenosis in patients with preserved LV function is referred to as damage suitable for balloon angioplasty. Such lesions, according to modern research, and
  11. Medical tactics for electric shock
    In case of electric shock, local and general disorders can occur. Local varies from minor pain points to specific burns (up to grade IV). General violations are in violation of the activity of the central nervous system, respiratory and circulatory organs. Shock, cardiac arrest and respiration are possible. Emergency care At the onset of clinical death, resuscitation measures are conducted.
