Clinical symptoms of electric shock?

summary

Electric shock is a relatively rare phenomenon in life, but if in the world, there are more electric shocks. Although there are few examples of electric shock in our life, it is also a potential danger in our life. Moreover, in some remote areas, there are many unsafe circuits. So, let me show you the symptoms of electric shock.

Clinical symptoms of electric shock?

General manifestations: slight pain muscle contraction, panic, pale complexion, headache, dizziness, palpitation, etc. after electric shock. High voltage electric shock, especially lightning stroke, often occurs loss of consciousness, heart is very good, respiratory arrest, respiratory arrest lasts for minutes, we should know that if not timely resuscitation will die. The survivors may have disorientation and epileptic seizures, some cases may have myocardial and conduction system damage, atrial fibrillation on ECG, myocardial infarction and non-specific ST segment reduction, hypovolemic shock may occur when a large amount of body fluid is lost at the tissue damage area or body surface burn. The main causes of acute renal failure are direct renal injury and necrotic muscle tissue producing myosin, hemolytic hemoglobinuria, renal tubular injury, dehydration and hypovolemia, which can accelerate the occurrence of acute renal failure.

Local manifestations: severe burns caused by high-voltage electric shock are common in the parts where electric current enters and goes in. The tissues of the burned parts are carbonized or necrotic and form holes. The burns around the electric shock are mild. If the clothes are ignited, large area burns unrelated to the electric shock parts may appear, High voltage current injury often leads to forearm lacunar syndrome. Due to muscle tissue injury, edema and necrosis, the pressure of the tissue under the muscle fascia increases, signs of neurovascular compression appear, pulse weakens, a lot of feelings and pain disappear, and fasciotomy is needed. Spinal compression fracture or shoulder dislocation may occur due to the ankylosing contraction of large muscle group after electric shock.

Complications and sequelae: serious arrhythmia, neurogenic pulmonary edema, gastrointestinal bleeding, disseminated intravascular coagulation, and bacterial infection secondary to burns often occur after electric shock. About half of the shock patients had unilateral or bilateral tympanic membrane rupture, and the nervous system lesions (ascending or transverse myelitis, multiple neuritis) could appear several days to months after shock; Visual impairment; Stillbirth and abortion often occur in pregnant women with unilateral or bilateral cataract after electric shock.

matters needing attention

The harm of electric shock is great, serious enough to be fatal. Therefore, we must understand the phenomenon of electric shock in our life, and we should not ignore it because it is rare.
