Lightning, Electric Shock, Burns
For patients with cardiac arrest, apnea, it is necessary to conduct emergency resuscitation by continuously pressing the heart about 100 times a minute, combined with breathing breathing about 2-3 times a minute.

Ms. Ha Anh, District 2, Ho Chi Minh City has not yet forgotten her husband's "death over and over again". After washing the clothes, she asked him to dry the wet clothes on the iron wire in the front yard. Iron wire accidentally shorted from the line in front of the house, he was electrocuted. "At that time, I panicked, didn't know how to handle it, just in time to call for help. Fortunately, a neighbor gave first aid in time and transferred to the hospital, not that he was dead," she said.
Doctor To Vinh Ninh, Head of Emergency Department of Gia Dinh People's Hospital, said that the hospital had received many cases of electric shock, mainly electricians, painters, welders, people who work as electricians, etc. related to electrical equipment… There are also quite a few cases of accidents when repairing electricity at home, even when repairing water tanks in the house.
When repairing other electrical appliances, usually people disconnect the circuit breaker and then proceed to repair. As for fixing the water tank, many people often forget that the water tank on the roof is also connected to electricity, forgetting to turn off the circuit breaker can be quite dangerous.
In addition, quite a lot of cases of electric shock are caused by drying wet clothes on conductive iron wires, touching electrical wires that have fallen on the road, into watery areas, people who light fish with electricity, traps with electric mice, etc. In case of emergency, the victim is a young child, because the household electrical outlet is too low, the electrical equipment is interfered, and the child accidentally touches it.
According to doctor Vinh Ninh, the danger of electric shock depends on the voltage level of the current, alternating current or direct current. With amperage below 30 mmA will not affect much, below 80 mmA will cause slight shock, from 80 to 300 mmA will be dangerous. In addition, there are factors such as how current flows through the body, the duration of the current exposure and the resistance of the contact tissue. With bone tissue, due to high resistance, it is less dangerous, with skin tissue, especially wet skin, the lower the resistance, the higher the danger level.
Normally, electric shock will lead to 2 injuries: burns and affects internal tissues. Burns include thermal burns that cause necrosis and burns that cause disorders of organs in the body, physiological disturbances, leading to risks: respiratory failure, heart failure, apnea. Depending on the level, the victim may faint and then regain consciousness, may also faint and then stop the heart, stop breathing, if not timely first aid can easily lead to death.
In addition, electric shock also causes muscle stiffness leading to broken bones or strong convulsions of the body's muscles, causing people to shoot, if they are on high, they may fall down causing injury. In many cases, the victim is electrocuted, the person sticks to the power cord, when the circuit breaker is disconnected, the victim let go of his hand and falls, which can lead to bodily injury.
Persons suffering from electric shock must be given first aid promptly and properly. First, immediately disconnect the power supply, separate the victim from the current. If you do not know where the circuit breaker is, you need to use pliers to cut the power cord or use a dry object (should use a plastic stick or dry wood, avoid using metal objects) to remove the power cord. Victims who are in an area with a lot of water should be removed from the water. Need to keep warm, avoid letting the victim get cold. Keeping the victim's body temperature is very important, especially in cold weather.
Never, out of panic, touch an electrocuted person without disconnecting the power. The first aid person himself should not use his bare hands but should wear rubber gloves or wrap a nylon bag, dry cloth, wear dry sandals, stand in a dry place when disconnecting the power.
"Many cases of patients fainting, waking up can still have complications in the next few days. Therefore, after the patient faints, it is still best to be taken to the hospital for examination and monitoring, the cases are slightly lost. Consciousness also needs to be careful," noted Doctor Ninh.
In case the victim has stopped breathing, has stopped breathing, if the patient is actively performing artificial respiration promptly and properly in the first few minutes, most lives can be saved. Many people, due to lack of first aid, died while waiting for the ambulance to arrive.
During this time, it is necessary to perform emergency resuscitation with rescue breathing and chest compressions. Should keep the hand in the middle of the patient's chest, hold it with the palm of the hand, press the heart continuously about 100 times a minute, continuously without stopping until the patient can breathe again. While pressing, the need to combine breaths with rescue breaths is about 2-3 times per minute, that is, on average, about 30 times of pressing the heart, give one breath. Keep doing this until the patient shows signs of breathing again.
It should be noted, when performing CPR and CPR, the victim must be placed in an open space, on a hard floor, placing on a bed with a settlement, such as a spring mattress bed, will make the heart has no effect.
Ninh said, many people wonder if the victim lying unconscious like that has stopped breathing, stopped breathing and needs first aid or not. In this case, still give breaths, rescue breaths and chest compressions as usual. If there is a breathing reflex, the victim will automatically pull his hand away.
There are many cases when the victim is burned, the family member splashes water on the skin, the resistance of the skin is reduced by 10-15 times, making the damage more severe. In addition, it is necessary to avoid applying measures such as shaving the wind, rubbing oil, which only takes more time in emergency treatment.
To prevent electric shock, it is necessary to observe the rules for safe use of electricity. Note, disconnect the power when repairing electricity, electrical outlets, electrical equipment need to be out of reach of children.
