Wonder if anyone can help. When cleansing a catheter port or area of the skin prior to cannulation etc. Should the area be cleansed for 30 seconds and allowed to dry for 30 seconds or have I just made this up in my own head? I am currently having a discussion with a colleague regarding this matter. This is the way I was taugtht when I first qualified (Sept '05). However my colleague says as long as the area is cleansed for just a few seconds and allowed to dry, this is sufficient. Although this would certainly save me time, I want to ensure that this practice is safe to use. Please help. I have searched on the internet and there are a few things to support my practice, but not enough to reassure me that my practice is necessary.
