How to irrigate a suprapubic catheter involves the use of 1 bottle of normal saline irrigation solution, 1 pre-packaged irrigation kit, and 1 catheter plug. Individuals are advised to wash their hands thoroughly before and after this procedure. First, individuals should place a towel over their thigh and under the connection area. Next, pour the saline solution into the collection container and draw about 15 to 20 milliliters of solution into the available syringe. Then, remove the plug from the end of the catheter. Next, use an alcohol swab to clean the area of the catheter. Then, gently enter the syringe into the end of the catheter and insert the solution. Next, remove the syringe and allow the solution to flow into the drainage container.
