If you are referring to the process before a surgical procedure it goes as follows. There are several different chemical scrubbing agents that can be use. Betadine is more historic, whereas chlorhexidine is now used. You wet your arms, open the brush/sponge with out touching the parts that you are going to place on your body. For long finger nails there is a nail scrubber to clean under the nails. You then start with the finger tips and completely scrub your hands continuing proximally to your elbows. You then rinse off your arms, not touching anything, and angle your arm so water flow down the arm towards the elbow.
New research has shown that scrubbing may cause microabrasions in the skin so most hospitals are adopting the policy of using Avagard which is an antibacterial gel that self drys. This is used after the first scrub of the day. Youmust also rescub if there are any activities performed that lead to lots of bacterial contamination (useing the restroom, eating, etc.)
