If a child has fever and convulsions, the first aid is divided into two parts, one is the first aid outside the hospital, and the other is the first aid inside the hospital. The details of out of hospital first aid are as follows: 1. When the family has fever and convulsions, the child should first be placed flat on the bed, and let the child lie on his side, so that some secretions or foreign bodies in the child's mouth can be discharged as far as possible, to avoid suffocation or inhalation pneumonia. If there is still some secretion in the mouth, you can use some dry towels or cloth to wipe it off properly. 2. The children's clothes should be untied immediately, especially the clothes at the collar to avoid breathing difficulties caused by choking at the throat. At the same time, untiing the clothes also has a cooling effect. If the convulsion caused by fever, the drop in temperature will also help the child to relieve the convulsion. 3. The child can be properly pressed by hand to stop smoking. 4. Put something between the two teeth of the child's mouth to prevent the tongue from being bitten. 5.
