Depends on the surgeon. Some like a 10 minute betadine scrub, betadine paint, then alcohol. Others prefer a 10 minute hibiclens, then alcohol, then Duraprep.
Whatever the prep, 10 minutes seems to be the norm for totals.
We don't use any betadine gel. I wonder how effective the gel is since there is no physical friction involved with the prep.
Other preps for general or gyn usually include a 3-5 minute betadine scrub and paint.
And I agree.....10 minutes is a LONG time to scrub!! My arms get a little tired by the end. However, it's the patient that benefits in the long run.
