Perform cardiopulmonary resuscitation according to the situation. Fall injury is the most common accident in Children's Home. Parents should take precautions and learn some basic first aid knowledge. Preventive measures: 1. Place anti-slip mats at the bottom of the bathtub and on the bathroom floor. 2. Teach children not to climb into high chairs or stand on seats. 3. Windows and balconies should be equipped with safety bars. Try not to put beds, cabinets and chairs beside windows or balconies to prevent children from climbing up and down. 4. When water and oil stains are found on the floor, dry them immediately. 5. the wire should be nailed to the wall or close to the wall, and it should not be dragged too long to prevent the child from tripping. 6. If the floor is sunken or damaged, it should be repaired immediately. In addition, the tile floor is slippery, so it is best to put a carpet on it, which can reduce the degree of injury even if the child falls. 7. Clean up the items on the floor properly to prevent children from accidentally stepping on and slipping. Parents should check the injury of the child who fell at home in the first aid. Generally, there will be fractures or abrasions, and more serious internal bleeding. At this time, the following first aid should be implemented: 1. The skin color of abrasions and injuries will be purple-blue, and there will be symptoms of swelling and pain. It is best to apply ice to the injured part as soon as possible to relieve pain, stop bleeding and reduce swelling. Then apply a hot water bag or a hot towel to the injured part to accelerate the blood circulation of the affected part to dissipate blood stasis. 2. Fracture If a child has a fracture after falling, it will generally hurt the injured part and its vicinity. When lightly pressing the injured part or moving the injured limb, the pain will be more severe, and you may feel or hear the rubbing sound caused by bone fracture. The most important principle in dealing with fractures is to try not to move the injured limb. If there is a wound at the fracture, stop the bleeding first, and then bandage the wound. Finally, the injured limb should be fixed with splint or board, scarf and tie. When fixing the injured limb, it is necessary to fix the upper and lower joints of the fracture site, such as the broken leg, knee joint and ankle joint, and pay attention to moderation. 3. Internal bleeding Internal bleeding is more terrible than external bleeding because it is not easy to be detected. Because internal bleeding can't be stopped by pressing, parents should inform medical staff to be present to assist in the treatment. Before the medical staff arrive, in order to prevent the injured child from moving, let him lie down, lower his head and lean to one side, so that his brain can get enough blood supply. At the same time, if the situation permits, you can raise your legs to make blood flow to important organs. In addition, we should pay close attention to the breathing, pulse and sobriety of the injured children, untie the collar and keep breathing smoothly.
