In the human survival needs of air, food and water and other elements to choose, no doubt, all people will be air in the first place. Indeed, just like a fish cannot live without water, people do not leave the air for a moment. If the airway, which is closely related to breathing, is blocked, what consequences will occur? First of all, please look at a real case. Qin××, male, 18 months old, presented to the clinic with recurrent cough and fever with lung infection for half a month. When he came to the ENT emergency room, the child was still breathing normally. The author was just about to conduct routine history taking and physical examination when the child suddenly turned red and purple after a violent cough, and in less than a minute, the child’s lips had turned gray. The clinical manifestations suggested that this child had a prolapse of a foreign body embedded in one side of the bronchus, obstructing the common airway and causing respiratory obstruction. The author picked up the child and went straight to the operating room and notified the anesthesiologist and nurse on standby to cooperate, and also informed the family of what had happened. After resuscitation, we took out half a peanut from the child’s trachea and the child resumed normal breathing. When we showed the family the half peanut and told them what had caused such a dramatic change in the child, the family came to their senses. It turned out that they had teased the child with the peanut half a month ago, after which he was treated for lung infection in the pediatric department of the local hospital for cough and fever, but often the symptoms recurred just after the medication was stopped. The original cause of repeated lung infections, almost caused asphyxia in the airway culprit is it DD half a peanut. Foreign bodies in the airway are one of the most dangerous emergencies in otorhinolaryngology (five gastroenterology). It mostly occurs in children who are not yet able to express and communicate well with their parents. We know that the thickest part of children’s airway is less than 1cm in diameter, and after the foreign body enters, children are often unable to cough it out, which can easily lead to lung infection, pneumothorax, emphysema, even asphyxia, death and a series of other serious situations. Parents also tend to ignore the presence of small particulate matter in their daily lives, often treating their children only as ordinary pneumonia after they have a cough and fever, which repeatedly delays the condition. This case presents a particularly aggressive situation, where a foreign body originally lodged in one bronchus is displaced into the common airway by choking and loosening, causing obstruction of the entire airway. In this case, the patient could be resuscitated in less than 5 minutes or even less. Fortunately, the entire medical team reacted quickly and rescued the patient in time, otherwise, a life would have fallen because of half a peanut. It should be noted that in the process of seeking medical attention, parents often fail to understand the serious consequences of similar emergencies, often contradict the hospital and the attending physician, believing that the child was in the hospital accident, the hospital caused such serious consequences. I believe that our readers should understand what is right and what is wrong, because the occurrence of such diseases is too sudden and dangerous, and the time left for the doctor to treat the airway obstruction is too short. The child in this case was lucky to recover, but there are still some children who have had their foreign bodies removed and their airways restored, but whose brains have been deprived of oxygen for too long, which can affect their growth and development. Imagine if the foreign body in the airway of this child had been displaced outside the hospital, the parents might have lost their son without even knowing the cause. Therefore, as the guardian of a minor child DD parents have a great responsibility and such accidents are better not to happen. Doctors recommend: children under three years of age are prohibited from eating peanuts, melon seeds and other granular food and jelly food, should not put such food and small granular toys at home, and promptly stop others from teasing children with such food; after the child is full especially should not do strenuous exercise (such as running and jumping, swimming, etc.) to prevent children vomiting after the food accidentally inhaled into the trachea. After repeated pulmonary infections have failed to be treated, a history of foreign body aspiration should be excluded. In case of foreign body misaspiration into the airway, try to keep the child quiet, avoid crying, reduce oxygen consumption, and seek prompt medical attention. A foreign body in the airway is a representative of many otorhinolaryngological emergencies, and it can take away the life of a child in a matter of hours or even minutes. We hope you will take this as a warning and not let a small problem turn into a big one.
