The harm of electric shock to organs is mainly skin and muscle burns, and in serious cases, it can lead to the dysfunction of vital organs such as the heart, kidneys and brain, and even directly cause death. Its specific introduction is as follows: 1. Skin and muscle burns: the electric shock will first damage the skin, skin burns, light local redness of the skin, lesion formation, severe skin, muscle tissue contracture, necrosis and other manifestations of the limbs. 2. Cardiac dysfunction: After receiving electric shock, the heart is damaged due to myocardial cells, resulting in myocardial cell membrane instability, thus inducing a variety of arrhythmias, such as ventricular tachycardia, ventricular fibrillation, etc.; and even lead to a decrease in the myocardial contraction force, triggering the heart’s pump dysfunction, a drop in blood pressure and other hemodynamic instability. 3. Renal dysfunction: acute renal injury is easy to occur after electric shock to the kidneys, leading to acute renal dysfunction, or hematuria, myoglobinuria, oliguria and other related manifestations of renal injury. 4. Cerebral dysfunction: cerebral dysfunction is also known as the impairment of the nervous system, light dizziness, nausea, fatigue and other symptoms, and in severe cases, may lead to coma. 5. Death: the intensity of the current is large, may directly lead to the patient’s cardiac and respiratory arrest, treatment is not timely, there may be death and other unpredictable circumstances. In short, the harm of electric shock to various organs are greater, need timely treatment.
