The "battle" of epidemic prevention and control is not completely over, and  schools and kindergartens have not yet started semester. Children are at home  for a long time, and some accidental injuries may occur. Parents should learn  simple preliminary on-site treatment methods while raising awareness of  prevention.

　　I. Burn injury. In daily life, flame burns and hot liquids such as hot  water and hot oil are the most common causes for scalds. Some parents would  apply toothpaste, egg whites, even soy sauce, red syrup, and etc. In fact, this  is not correct. It will cause trouble for doctor's diagnosis and treatment. 1.  You should first rinse and soak the wound with a lot of cold water to cool it  down. 2. Take off or cut the clothing covering the wound. If there is adhesion,  you can soak it in cold water and gently remove it. Do not remove it with force,  or it may aggravate the injury. 3 If you have blisters, it is not recommended to  needle it yourself. You could use a clean gauze to protect the wound. 4. If the  blister is too large and any move may broke it causing infection, you could use  a sterile sewing needle (infected with alcohol wipe or flame) to pierce the  bottom of the blister, slowly release the liquid, and then retain the epidermis,  protect it, and go to the hospital for treatment as soon as possible.

　　II. Fractures. Children are energetic. They like to play and jump around.  Their poor self-control ability and ability to identify and judge danger may  cause accidental injuries easily, and some fractures are not very obvious. Even  if the child is too young to speak, it is possible to preliminarily judge  whether there is a possibility of fracture through their reaction and body  language. 1. The child cries when he or she is injured, and does not stop crying  after comforting. 2. Local skin is swollen and painful when touched. 3 The  injured limb has a movement disorder, and the actions that are usually done  easily cannot be done now. 4. The injured limb is more asymmetrical than the  contralateral limb. 5. The child may show a protective posture if he or she has  fractures. For example, if the child's clavicle fractures, he will involuntarily  move his head and shrug to protect the damaged clavicle.

　　III. Electric shock. In the event of such an accident, the rescuer must  immediately cut off the power supply to ensure that the person will no longer be  injured by the current before rescue. 1. Rescuers should also pay attention to  the risk of electric leakage, such as whether their hands are wet. 2. It is  suggested to use insulated objects to pick up or cut off the live wires, lights,  sockets and other live objects on the person. You can choose dry wooden  materials. It is necessary to immediately check the breathing and heartbeat. If  the shocked person has a sudden cardiac arrest, cardiopulmonary resuscitation  can be performed on the injured before the medical staff arrives. Normally,  children should be educated not to touch dangerous items such as sockets and  wiring boards. Household appliances should be used by children with the care of  parents.
