In one sentence, describe what the following article is about: It is important to keep the tracheal tubes clean and free of mucus and foreign debris, so it's advisable to clean them at least twice a day once in the morning and once in the evening is ideal. However, the more frequent, the better. Here's what you need: Sterile saline Half-diluted Hydrogen Peroxide ( portion water mixed with portion hydrogen peroxide) Small, clean bowls Small, fine brush . It is essential that you wash your hands and remove all germs and dirt. This will help prevent any infection due to unhygienic care. The proper procedure for washing your hands is discussed above. The most important things to remember are to use a mild soap, lather your hands well, rinse them, and dry them with a clean, dry towel. In one bowl, place the strength hydrogen peroxide solution, and in another bowl the sterile saline solution. Remove the inner tracheal tube carefully whilst holding the neck plate still, which should be taught by your doctor or nurse while in the hospital. Place the tracheal tube in the bowl containing hydrogen peroxide solution and let it soak completely until the crusts and particles on the tube are softened, dissolved and removed. Some tracheal tubes are disposable and don't need to be cleaned if you have replacements. Using a fine brush, clean the inside and outside of the tracheal tube carefully ensuring it is clear of mucus and any other debris. Take care not to be too firm and avoid using rough/coarse brushes for cleaning as this may damage the tube. After you're done, place it in saline water for at least another five to 10 minutes to soak and become sterile. If you don't have any more saline water, soaking the tube in white vinegar diluted with some water will work also. If you're using disposable plastic tracheal tubes, then skip this step and throw out the tube. Once you've got a cleaned and sterile (or new) tracheal tube in hand, carefully insert it back into the tracheostomy hole whilst holding the neck plate still. Turn the inner tube until it locks back into position securely. You can gently pull the tube forward to make sure that the inner tube has locked into place. This successfully completes your cleaning procedure. Performing this at least two times per day can prevent infections, clogging and other complications.
Summary: Gather your materials. Wash your hands Soak the tracheal tube. Clean the tracheal tube. Place the tube back into the tracheostomy hole.
