What are the sequelae of electric shock?

The convenience that the invention of electricity has brought to mankind is self-evident. However, due to the extremely large current used in some industrial electricity, once someone gets electrocuted, there is often no chance of escape. Even if they are rescued by chance, it will still cause very serious effects on people and leave sequelae. Next, let’s talk about the sequelae of electric shock. I hope everyone will be vigilant and take precautions.

Sequelae of electrical injury

Most of the electric shocks people usually encounter are from 220-volt household electricity or 380-volt industrial electricity, not high voltage electricity. If you are electrocuted and there is no one nearby to rescue you, you need to stay calm and save yourself. Because in the first few seconds after being electrocuted, the person is in a state of mild electric shock and has not lost consciousness. Rational and orderly judgment and handling are the key to successful rescue. After getting an electric shock, people will not be sucked as people usually imagine. It is just that alternating current can cause continuous spasm and contraction of muscles, so after getting an electric shock, the hand will grab the power source and the grip will become tighter and tighter. At this time, the person who is electrocuted can use his other free hand to quickly grab the insulation of the wire and pull the wire out of his hand to relieve himself from the electric shock. If the appliance is fixed to the wall when you are electrocuted, you can push the wall hard with your feet and fall backwards at the same time, using your body weight and external force to get rid of the power source. People who are able to free themselves from electric shock generally do not suffer from sequelae such as deafness, visual impairment, menstrual disorders, mild personality changes, etc.

Electrical injuries are injuries caused by electric current passing through the body. It is usually caused by accidental electric shock or lightning strike. Generally, 24 volts is safer. Severe electric shock injuries may cause severe muscle spasms, respiratory and cardiac arrest, and rapid death. It is often accompanied by brain trauma, abdominal trauma, and fractures. Patients with mild symptoms only feel dizziness, palpitations, nausea, pale complexion, cold sweat, and tremors. Electrocardiograms may show signs of myocardial damage.

Electric shock may cause severe burns in the form of points or large areas. The injured limbs may become temporarily paralyzed. In very rare cases, mental disorders, blindness, or deafness may occur. The consequences of high voltage electric shock and lightning strike are serious and can often lead to rapid death. After an electric shock occurs, you must first cut off the power supply, turn off the switch or use an insulating object to pick up the wires or electrical appliances, or use an axe with a wooden handle (dry) to cut the wires. Never pull the patient directly with your hands.

If breathing stops, perform mouth-to-mouth artificial respiration immediately, followed by endotracheal intubation and use of a ventilator to maintain breathing. If the heart stops beating, immediately tap the precordial area several times. If there is no heartbeat, perform external cardiac massage. If conditions permit, consider opening the chest and directly squeezing the heart. Comprehensive treatment is still required after the patient is resuscitated.

Strictly follow the electricity usage system, master the basic knowledge of safe electricity use, cut off the power supply in case of fire or typhoon, avoid walking in the wild or take shelter under large trees during thunderstorms, etc., which can effectively prevent electric shock.
