How should a nurse cleanse the area when assisting with the insertion of a central line into the subclavian vein?

The correct cleansing method for assisting with the insertion of a central line into the subclavian vein involves using chlorhexidine in a back and forth scrubbing motion. This technique is preferred because chlorhexidine is an effective antiseptic that provides a longer-lasting antimicrobial effect compared to other agents. The back and forth scrubbing motion ensures that the antiseptic adequately penetrates the skin's surface and minimizes the risk of skin flora contaminating the insertion site.

This method is supported by guidelines emphasizing the importance of proper skin antisepsis before any central line insertion procedure to reduce the risk of catheter-related bloodstream infections. Chlorhexidine is particularly advantageous due to its rapid action and residual activity, making it more effective than simpler methods such as using an iodine prep pad or soap and water, which may not provide the same level of bacterial reduction.

In summary, using chlorhexidine with a scrubbing motion is the most effective technique for cleansing the area, ultimately enhancing patient safety during the procedure.
