How to give first aid after an electric shock?

  Clinical often see electrocution patients were sent to the hospital emergency room by ambulance, medical staff then carry out intense rescue work, but the rescue results are not satisfactory, the patient mortality rate is still very high.  Why is the mortality rate after electrocution so high? The most common reason is that after a patient is injured by electrocution, electrocution first aid, that is, cardiopulmonary resuscitation, is not performed in a timely manner within the first hour.  How to perform first aid for electrocution? To summarize it is to do 8 words: fast, in situ, correct, and continuous.  1, fast: refers to the seconds, immediately the electrocution from the power supply. The method of disconnecting from the power supply depends on the specific situation, such as quickly disconnecting the power switch, using insulated bamboo poles to pick open the landing low-voltage wires. In case of high-voltage power line break down, to quickly notify the power supply bureau by phone, then only to carry out rescue and relief work. Remember that the high-voltage line is bare wire, no insulating jacket, so it should be directly touched by hand. …… (please add the correct practice).  2, in situ: means that the rescue must be carried out in situ at the scene of electrocution, do not transport long distance. If the electrocution will be sent to the hospital emergency, will inevitably delay the valuable rescue time, resulting in death by resuscitation. From the current medical theory, the human brain resistant to hypoxia can not exceed 10 minutes, once more than that time, the probability of irreversible necrosis of brain cells will be significantly increased.  3, accurate: refers to the artificial CPR action must be correct. After the electrocution from the power supply, should immediately use the “look, ask, listen, try” method to make it lie on its back, and keep the airway open.  Look: look at the injured person’s chest, abdomen with or without undulating action; ask: call or tap the injured person’s shoulder to see if he or she responds, quickly determine whether his or her consciousness, autonomous breathing and heartbeat is present; listen: ear close to the injured person’s mouth and nose, listen to the sound of exhalation; test: fingers close to the mouth and nose, try to test whether there is exhalation airflow, and then two fingers lightly test the carotid artery in the recesses of the larynx on one side for fluctuations.  Through the above examination, if there is no breathing and no pulse should be immediately resuscitated with cardiopulmonary resuscitation. The correct method is: First, mouth-to-mouth (nose) artificial respiration. Resuscitator inhale enough air, pinch the casualty’s nose, close and cover the lips of the mouth, blow 800-1200ml, 14-16 times / min.  Second, external chest cardiac compressions. This position is located at the midpoint of the line between the two nipples, the left and right fingers crossed tightly, elbow joint straight press, so that the thorax sinks 5cm, 100 times / min, the palm heel can not leave the chest when pressing. Artificial respiration and chest cardiac compressions ratio of 2:30. 4, insist: as long as there is 1% hope, we must today 100% effort to rescue, to be identified after the arrival of doctors.
