The main purpose is to expel the rice grains out of the body and prevent the emergence of aspiration pneumonia. Generally, you can inhale deeply and exhale the gas as vigorously as possible to increase the pressure in the trachea so that the rice particles in the airway are compressed out. If you are unable to cough up the rice grains several times, you can choose to remove the rice grains under bronchial fiber endoscopy at this time to prevent the occurrence of aspiration pneumonia. Antibiotics such as penicillin, clindamycin, cefoperazone, etc. can be used appropriately at this time.
