Before scrubbing, what should assistants do to clean their nails?

Cleaning nails is a critical part of surgical hand hygiene, as this helps reduce the risk of introducing pathogens into the surgical field. Using a nail file or nail pick before scrubbing is essential because it allows for the thorough removal of debris and microorganisms that might be trapped underneath the nails. This practice helps ensure that the hands are as clean as possible before any surgical procedures begin.

While other methods of cleaning nails may have their place, they do not address the specific need to clear out accumulated dirt or debris from beneath the nail edges effectively. For example, soaking in antiseptic does not adequately remove dirt, while scrubbing with soap may not reach under the nails. Trimming nails short is also important for overall hygiene and reducing contamination risk, but without the use of a file or pick, any residual debris may still be present, negating the full benefits of scrubbing with antiseptic afterward.
