If a grain of rice enters the trachea and cannot be coughed out on its own, it can be removed by tracheoscopy. A grain of rice entering the trachea will usually be coughed up by coughing; if it cannot be expelled, it needs to go to the hospital in time, and it can usually be removed by tracheoscopy because the size of the grain of rice will be confined to the bronchial tubes, and can be removed by tracheoscopy. If it enters the trachea for a short period of time, there is no inflammation in the body, usually no treatment is needed after tracheoscopy; if it has been in the trachea for a long period of time, it will cause inflammation in the body, then, after removing it through the tracheoscopy, it is necessary to take antibiotics (such as amoxicillin, etc.) as prescribed by the doctor. If the above situation occurs, please consult a doctor in time for reasonable and standardized diagnosis and treatment, and the use of drugs needs to be carried out under the guidance of a professional doctor.
