The presence of yellow sputum, if caused by bronchiectasis, takes a longer time to treat. First of all, in the acute stage, it is necessary to choose appropriate and sensitive antibiotics for intravenous oral or drip treatment based on sputum culture, which is more effective. In addition, you need to use cough expectorants, such as amylin, myrtle oil, lung power cough combination, and compound fresh bamboo liquid. Postural expectoration is needed every morning and evening, which is more effective for treating bronchiectasis and preventing the aggravation of bronchiectasis. The patient can adopt a frog position, and then the person next to the patient can help to gently pat the back, and the patient can cough gently for a few times, and the sputum can be coughed out more easily. If an acute respiratory infection occurs, causing yellow sputum, it is more effective to select appropriate and sensitive antibiotics for intravenous drip treatment according to the type of infection. In addition, it is also important to take cough and phlegm relieving drugs, such as Ambroxol Hydrochloride and Ambroterol Oral Solution.
