When sterilizing instruments, what should be done regarding rubber tubing?

When sterilizing instruments that include rubber tubing, it is important to leave a residual of distilled water inside the lumen when using steam sterilization. This practice is essential because the presence of a small amount of moisture helps facilitate the penetration of steam throughout the tubing, ensuring that all surfaces are adequately sterilized. Without this moisture, steam may not effectively reach all areas of the tubing, which can leave pockets of contamination.

Additionally, leaving distilled water inside the rubber tubing during the steam sterilization process allows for better heat transfer and can help prevent physical changes to the rubber material that might occur if it were completely dry. This method also ensures that the rubber tubing does not become damaged during the sterilization cycle, maintaining its integrity for future use.

In contrast, soaking rubber tubing in alcohol or insisting that it must be completely dry before sterilization would not provide the same level of effectiveness in the sterilization process and could potentially compromise the functionality of the tubing. Furthermore, restricting usage of rubber tubing by residents does not address the proper sterilization practices required.
