There are several treatments for sputum embolism: medication, suction, postural or manual assisted expectoration, bronchoscopy and so on. Phlegm embolism can be formed when the patient has more sputum and thicker sputum. Phlegm embolism can block the small airways, affecting the patient’s respiration, which can lead to respiratory difficulties or even death in serious cases; however, when considering phlegm embolism, it can be treated by the following methods: 1. Medication: medicines can be used to dissolve phlegm, such as oral solution of Ambroxol, oral granules of acetylcysteine, etc., and medicines can be nebulized to dissolve phlegm, such as inhalation of acetylcysteine, or intravenous Ambroxol in serious cases. 2. Suction: If the hospitalized patient is weak in sputum expectoration, the nurse may be asked to suction. 3. Position or manual assisted sputum expectoration: patting the patient’s back can help the patient expel sputum, and the adjustment of position can also promote the drainage of sputum, so that the sputum can be more easily discharged. 4. Bronchoscopy: If the above methods are not effective or the sputum plug is in the deep airway, the sputum plug can be removed by bronchoscopy. The above are several treatments for phlegm embolism, once the formation of phlegm embolism is found, it is recommended to treat it as early as possible and follow the doctor’s instructions.
