When a toddler cries, laughs, runs and jumps while eating or suddenly inhales deeply with a small object in his mouth, it is very easy to inhale a foreign body into the trachea. With the action of breathing, the foreign body will enter the trachea, bronchus or its deep part, which can cause coughing and choking, bruising and breathing difficulties in young children. Some of the foreign bodies that enter the trachea are not detected in time and often become infected secondary to fever and cough, similar to the manifestations of chronic bronchitis, pneumonia or pulmonary swelling and pus. Larger foreign bodies that are inhaled can die due to obstruction in the voice box or tracheal cavity, causing strong stimulation and tracheal spasm or voice box closure, and young children can immediately develop cyanosis, asphyxia, and death. Parents should be fully aware of the dangers of tracheal foreign bodies and pay attention to the prevention of tracheal foreign bodies in young children. Once a tracheal foreign body occurs in a child, parents should not take any chances and should immediately race against time to send the child to the hospital for treatment. This is because the chances of young children coughing up foreign bodies naturally are rare, and only in the conditions of the hospital operating room can foreign bodies be removed with a laryngoscope or tracheoscope. Therefore, parents must realize the importance of timely treatment and must not lose time, otherwise the consequences are unthinkable. To prevent the occurrence of foreign bodies in the trachea of young children, avoid crying, laughing, running and jumping when they eat, and chew and swallow slowly. At the same time, do not give young children to eat fried beans, peanuts, melon seeds and other food that is not easy to chew, and do not force feed medicine, which can easily cause the occurrence of foreign bodies in the trachea of young children. In addition, avoid storing small items, such as small buttons and pins, in the children’s activity area to prevent accidents.
