Because children’s cough reflexes are not well developed, choking symptoms can occur if parents are not too careful when giving medicine to their children and forcefully administer the medicine when the child is crying and aspirated. The coughing symptom is characterized by violent choking and continuous coughing, and the child will cough until his or her face is red. In addition, if the child coughs more severely, it can lead to aspiration pneumonia. However, if the amount of fluid choked into the airway is relatively small, the child’s cough reflex will expel the fluid. Only a small amount of fluid choked into the trachea will also be slowly absorbed through the blood vessels of the trachea. Only if a large amount of fluid is choked, the child will get aspiration pneumonia, which can be treated by flushing with fiberoptic bronchoscopy. Therefore, when giving medicine to your child, you must be careful to avoid choking into the trachea as much as possible.
