Using distilled water in the lumens is essential for preparing a Frazier suction tip for steam sterilization because it helps to eliminate residual debris and allows for thorough penetration of the steam inside the narrow lumens of the suction tip. When the lumens are filled with distilled water, it creates a more effective environment for the steam to interact with the surfaces, promoting proper sterilization throughout the device.

This approach ensures that any contaminants trapped inside the lumens are adequately addressed, as steam is the sterilizing agent used in this method. The introduction of distilled water enhances the steam's efficiency, maximizing the effectiveness of the sterilization process.

Other methods, such as soaking in alcohol or immersing in saline, may not provide the same level of sterilization, as alcohol could leave residues and saline could create potential for the formation of biofilms within the lumens. Similarly, drying with a cloth may not ensure the removal of all contaminants and could introduce fibers into the suction tip. Therefore, filling the lumens with distilled water stands out as the proper preparatory method for effective steam sterilization of the Frazier suction tip.
