When choking on a grain of rice in the trachea, it will usually irritate the trachea and cause a violent cough, but if it cannot be expelled after coughing, and if there is difficulty in breathing, it is necessary to use the Heimlich maneuver in time, which can help to expel the grains of rice, and if it is still impossible to expel the grains of rice, it is recommended to consult the doctor in time, and then remove the grains of rice under the bronchial fiberoptic endoscopy. Choking into the airways and obvious coughing symptoms, the patient should be appropriate strength to beat the back or abdomen, to help the choking into the airways of the rice cough out of the body. If respiratory distress occurs, the Heimlich maneuver should be used promptly. For conscious adults and children older than 1 year of age, abdominal percussion should be used; for infants younger than 1 year of age, back percussion and chest compressions should be used; for those who are in a coma and are not breathing, cardiopulmonary resuscitation (CPR) should be performed; and for pregnant women or obese people, chest percussion should be used. If you are unable to expel the rice particles after taking the above two methods, you should go to the hospital in time for examination and have the rice particles removed by a professional doctor under the bronchial fiberoptic endoscopy. Patients who can’t cough up the rice particles choked in the airway should go to the hospital in time and choose the appropriate method of treatment.
