If a grain of rice is stuck in the trachea, at this time we can try to cough out the rice grain by coughing vigorously. If it doesn’t work, you can put your upper abdomen against the back of a chair, the corner of a table or a railing, and forcefully impact your upper abdomen to try to make the airflow in the trachea flush out the rice grains. If it still doesn’t work, you need to go to the hospital quickly and let the doctor take care of it. Usually the doctor will take out the rice grains through bronchoscopy. Before doing the bronchoscopy, the doctor will also ask you to do some related tests, such as blood count, coagulation and virus-related tests. The doctor will also ask you to do some tests before the bronchoscopy, such as blood tests, coagulation tests and viral tests to see if there is any anemia, coagulation abnormalities and infectious viral diseases. If there is no abnormality, bronchoscopy can be done, and the doctor can take out the rice through the bronchoscope. After taking out the rice, anti-infection treatment should be carried out, and oral antibiotics can be used for treatment.
