After working in otolaryngology for several years, tracheal foreign bodies in children are the most disturbing. Many parents are negligent in caring for their children in normal life, and some parents even know nothing about it. A tracheal foreign body is an ENT emergency and can be life-threatening if not treated promptly or appropriately, so it should be brought to the attention of parents. Tracheal foreign bodies often occur in children under 5 years of age, especially under 3 years of age, and are relatively rare in adults. The following reasons are mainly considered: 1. Children are curious about new things and like to put small objects into their mouths; 2. Children’s chewing function is not perfect, and the function of the larynx is not yet perfect; 3. Parents do not have proper parenting experience, and are not aware of what to eat and what not to eat; 4. Children like to cry, and they are easy to inhale by mistake when eating; 5. Foreign bodies from the mouth and nose are not handled properly and fall into the airway. There are various kinds of tracheal foreign bodies seen in the clinical work. These include beans, fruits (broken pieces), melon seeds, peanuts, small objects on toys, buttons, jellies, and so on. Soft foreign bodies such as jelly are the most dangerous (because they completely block the airway, the child is almost suffocated by the time he comes to the hospital). The trachea is the only way to breathe, once the foreign body is mistakenly blocked into the trachea, the lighter the difficulty in breathing, lack of oxygen, the heavier the complete asphyxiation. Here’s how to prevent it: Young parents should recognize the danger of foreign bodies in the trachea and pay enough attention and vigilance! Strengthen the education of young children so that they can develop good habits. Also actively go to professional institutions or hospitals to learn the protection of children. children under 3 years of age should never eat appeal food; toys purchased for children should be large, no small decorations that children can not put in the mouth; small items at home such as buttons, small coins should be put out of reach of children. Special reminder: When a child accidentally puts a foreign object in the mouth, parents should not force their hands to pick it out. Often this will cause the child to cry and the foreign body will be transferred into the airway. For foreign bodies in the nasal cavity, immediate hospitalization is recommended. If the foreign body has already entered the airway, parents should not panic and should seek immediate medical attention as it is unlikely that the foreign body will be coughed up on its own. Keep a close eye on the child’s breathing and preferably lie down when transported. Back patting and feeding may aggravate the condition.
