Electrocution is known as electric shock injury in clinical medicine, and the voltage level is one of the influencing factors affecting the degree of harm to the human body from electric shock injury, but not the only influencing factor. Therefore, whether it is high-voltage electrocution or low-voltage electrocution, first aid methods are not essentially different, can be divided into the following parts: First, to make the electrocution from the electricity, can be used to close the electric gate, cut the wire, pick open the wire, pull the electrocution and other means, in the above process must be strictly maintained and the electrocution insulated, can not directly touch the electrocution, the choice of equipment must also be insulators. If necessary, place dry wooden boards, thick plastic and other insulating items underfoot after the operation, so that they are insulated from the ground. Next, assess the state of consciousness of the electrocution victim, and if there is a loss of carotid pulsation and cardiac arrest, immediately give the electrocution victim cardiopulmonary resuscitation. Patients may be in a pseudo-dead state after low-voltage electrocution, and CPR must be continued until the patient is awake or resuscitation fails completely, and should not be given up easily. Finally, it is necessary to go to the hospital immediately for systematic examination and related treatment, mainly symptomatic treatment, mainly to maintain respiratory and blood pressure stability, actively prevent and treat cerebral edema, prevent and treat acute renal failure and other complications, use early cooling therapy, correct water-electrolyte and acid-base balance imbalance, and prevent infection. Attention needs to be paid to prevent spinal cord trauma when moving patients, and electrocution victims should be routinely injected with tetanus antitoxin. If there are burn wounds, disinfection bandages are needed at the wounds to avoid infection.
