Before sterilizing an instrument with a lumen, what must be done?

To effectively sterilize an instrument with a lumen, it is essential to inject distilled water into the lumen before the sterilization process. This step helps ensure that the instrument is adequately prepared for sterilization by allowing the sterilant to reach all surfaces within the lumen. The presence of moisture assists in the sterilization process, particularly when utilizing steam or other types of sterilants that require moisture for effective microbial kill.

Ensuring the stylet is within the lumen would not be advisable for sterilization, as it can prevent proper access of the sterilant to inner surfaces. Allowing the instrument to dry completely goes against the principle of providing the necessary moisture to facilitate effective sterilization. Wrapping the instrument in a peel pack pouch is important for transport and storage but does not address the need for proper preparation of the lumen before sterilization. Therefore, injecting distilled water into the lumen is the critical and correct step to prepare such instruments for effective sterilization.
