Your baby must be in quiet when eating. If your child cries or runs while eating, foreign bodies such as food entering the trachea and bronchi are very dangerous and can cause sudden death, which can be due to untimely diagnosis and delayed treatment, leading to serious complications such as bronchitis, bronchiectasis, emphysema, atelectasis, pneumonia and lung abscess. Therefore, it is important to prevent the problem before it happens and to take active preventive measures. Foreign bodies in the respiratory tract are completely preventable and should be widely publicized to parents and caregivers of children. Children before the age of 5 should not be given peanuts, melon seeds, beans and other foods with nuclei, small toys should not be given to children orally, nor should they jump and play while eating to avoid inhaling food when they fall. When eating, do not scare, tease or scold to avoid crying and laughing. Any object that may be inhaled or swallowed by the child should not be used as a toy. Treatment: Foreign bodies that have entered the trachea or bronchus have only a 1-4% chance of being coughed up naturally, so they must be removed. Generally, the foreign body can be removed from the trachea or part of the bronchus by direct laryngoscopy; for bronchial foreign body or cases with unclear diagnosis, bronchoscopy can be applied to remove the foreign body. If laryngeal edema occurs due to damage to the larynx from the removal of foreign body, 1-2 days of antibiotics and hormone therapy should be given after surgery. In case of accidental inhalation of liquid material, coughing should be promptly stimulated, or a catheter should be placed into the trachea via the nasal cavity to attract, or direct laryngoscopy or bronchoscopy if necessary.
