Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query Duolin, the medicine is a bronchodilator. So it helps expand the lungs, which makes the patient feel more comfortable when breathing. However I am not convinced with the idea of using it without testing. Secretions so much so that you need to arrange for suction suggests that there may be an ongoing infection in the lungs. It would be a good idea to get an x ray of the chest, Since you are already getting the suction done, a suction sample may be sent for cultureS, This will tell us the bacteria growing and the antibiotic suitable to treating the infection I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further. (If the answer has helped you, please indicate this) Best of luck. Dr Mittal.
