Lightning injury and its ambulance
In the summer evening, the sky was overcast, heavy rain, a lightning strike through the sky, and there was a faint thunder in the distance.
Suddenly, the phone in the rescue room rang quickly, and a residential community found someone lying in the muddy rain, life and death are unknown.
When our ambulance arrived at the scene, the medical staff found that the face and lips of the wounded had been bruised, the pupils were loose and fixed, the arterial pulsation disappeared, and the breathing stopped.
The injured person was about 20 years old, and the bag was slanted with test questions and reference books. He held a mobile phone in his hand.
The fingers have burnt marks.
Judging from the scene, the injured person may be injured by lightning and sudden cardiac arrest.
We urgently performed on-site cardiopulmonary resuscitation, but because of the shortened cardiac arrest time, the rescue did not help.
Summer is a season of thunderstorms. In addition to economic losses, the disaster caused by lightning can even cause personal injury and threaten people’s lives.
According to historical records, the Palace of the Taihe Temple was once burnt by lightning, and the number of deaths is unknown.
Thunder and lightning can cause harm to the human body In an era of underdeveloped science, people are full of horror of thunder and lightning. They think that it is the god of anger and punishes those who are guilty.
Later, transforming the development of science, people gradually learned that lightning is a natural phenomenon.
Lightning is a huge electric spark.
Human beings are electrical conductors. If they are directly hit by the lightning and are transmitted to the ground through the main shaft body, the heart and nerves can be paralyzed. At this time, the heart may stop beating, or ventricular fibrillation may occur, that is, the heartbeat is extremely irregular, and the heart cannot be effective.The ground is shot, the person who is crushed has no pulse, no blood pressure; the damage of the brain nerve can directly inhibit the heartbeat and the respiratory center, causing death within a few.
In addition, although it is not directly hit by lightning, it can cause an accident.
This is because when the human body is close to the lightning strike point, a part of the lightning current can enter the human body through the “step voltage”.
Thunderstorm weather should remember: ● When you are lightning, first close the doors and windows to prevent lightning from entering the house.
● Indoor personnel are away from metal objects such as doors and windows, water pipes, and gas pipes.
● Avoid using a solar water heater to bathe during lightning.
● Try not to use electrical appliances during lightning, and unplug the power plug to prevent lightning from entering the power supply.
● Do not call when lightning, especially if you can’t call the mobile phone. The young student who went to the first aid is probably deadly when I hit the mobile phone during lightning.
●Pedestrians on the road during lightning, when they are sheltered from the rain, they cannot approach closed high-rise buildings, poles, chimneys, towering corners, billboards, towers, etc., and they cannot stand in the open high ground or under the trees to hide from the rain.Try to find low-lying or squats to lower your body height.
● Stop swimming, boating, fishing and other water activities immediately.
● If multiple people are in the same place, do not squeeze each other to prevent the current from being connected to each other after being struck by lightning.
How should we save ourselves in the event of a lightning disaster?
In the summer when lightning is frequent, people should pay great attention to lightning protection and master some methods to save first aid.
Start with a burn, if the clothes are on fire after being injured by lightning, you should lie down immediately, roll on the spot, or climb in the watery depression, in the pool, so that the flame does not burn the face, in order to prevent respiratory suffocation and death.
The rescuer can pour water on the injured person to extinguish the fire, or use a thick coat and a blanket to extinguish the fire.
The injured should remember not to run scared, which means that the fire is burning more and more.
The burns can be rinsed with cold water and then wrapped in a clean cloth such as a clean handkerchief.
If there is a sudden drop in the lightning, the lips are blue, sigh like breathing or not breathing, loudly calling no reflection, indicating that the injured person lost consciousness, respiratory heartbeat sudden stop.
Immediate on-site cardiopulmonary resuscitation should be performed.
According to statistics, if the cardiopulmonary resuscitation can be effectively performed within 6 minutes of the heartbeat of the injured person, the survival rate of the rescue can reach more than 40%, but if the time is delayed, the survival rate of the rescue is significantly reduced.
If the cardiopulmonary resuscitation is performed 15 minutes after the heartbeat stops, the hope of survival of the injured person is almost zero.
Moreover, even after the heartbeat of the injured person has stopped for 6 minutes, even the recovery is successful, which also brings serious sequelae to the nervous system, such as long-term coma and death.
On-site cardiopulmonary resuscitation is also called primary life support, including artificial respiration and heart failure.
The specific method is as follows: firstly, the injured person is transferred to a safe place (at the same time pay attention to the safety of emergency personnel), and then the injured person is gently placed on the ground gently, the rescuer’s legs are separated, and the complications on the injured person areThe index finger and the middle finger are close together to hold the injured person’s ankle and keep the airway open.
Wrap the wounded person’s mouth with his own mouth, and squeeze the injured person’s nose with the other hand. After inhaling, blow the injured person’s lungs hard, see the injured person’s chest swell, then relax the hand and put the opening.I saw the wounded eyes fall back.
After two consecutive insufflations, the heart is suddenly killed.The palm of one hand is placed on the intersection of the injured sternum and the two nipples, close to the injured chest wall, the other hand is overlapped in the first hand, vertically inserted by the body’s gravity, causing the injured thorax to sink 4-5 cm, bias frequency is about 100 times per minute.
First, the heart contracts 15 times, and the mouth-to-mouth artificial breath type blows 2 times.
Calling 120 at the same time as cardiopulmonary resuscitation is expected to transition to advanced cardiopulmonary resuscitation in time
Expert Tip: The 2005 new cardiopulmonary resuscitation guidelines suggest that the adult first aid life chain includes: early identification of cardiac arrest, call 120; early on-site cardiopulmonary resuscitation (CPR); early defibrillation; early advanced life support (ACLS).
This can greatly improve the success rate of rescue.
