Electric shock occurs occasionally in people's lives, and mastering the first aid principles after an electric shock is of great significance for timely treatment.
1、 Symptoms
Local manifestations include varying degrees of burns, bleeding, and blackening. The boundary between the burn area and normal tissue is clear. Or systemic dysfunction, such as shock, respiratory and cardiac arrest. The cause of death is due to the high inhibition of the brain (the respiratory center of the medulla oblongata) and the inhibition of the myocardium caused by electric current, resulting in ventricular fibrillation. The damage caused by electric shock is related to voltage, current, and the condition of the conductor in contact with the body surface. High voltage, electrical
Strong current, low resistance, and moist body surface can easily lead to death: If the current is only transmitted from one limb or body surface to the ground, or if the limb is dry and has high resistance, it may cause burns and may not necessarily lead to death.
2、 First Aid Principles
1. After discovering someone who has been electrocuted, immediately cut off the power supply, pull down the switch, or use non-conductive bamboo or wooden sticks to separate the conductive body from the electrocuted person. Do not touch the person who has been electrocuted while the power supply is not cut off or the person who has been electrocuted is not disconnected from the power supply;
2. For those who have stopped breathing and heartbeat, boxing resuscitation or mouth to mouth artificial respiration and chest compression should be performed immediately until breathing and heartbeat are restored. If breathing does not recover, artificial respiration should be maintained for at least 4 hours or when there is stiffness and necrotic plaques before giving up rescue. It is better to inhale oxygen directly when conditions permit;
3. During on-site rescue, call medical personnel or seek assistance from relevant medical units as soon as possible. Use respiratory center stimulants to acupuncture the acupoints of Zhonghe and Shixuan in humans. Prohibit cardiac stimulants before cardiac arrest.
3、 Prevention
Strengthen education on safe electricity use, regularly inspect and repair electrical equipment, comply with electricity usage regulations, do not connect wires randomly, do not dry clothes on energized wires, and do not touch broken wires; Do not stand on high walls, under trees, near electric poles, or near antennas during thunderstorms.
