Prep solution for open wounds

We use betadine paint but I've been told that it isn't "approved" for use in open wounds. I did some research on ChloraPrep and Betadine and one article suggested that Betadine is so old that it's indicated uses were grandfathered in by the FDA whereas other prepping agents are forced to follow stricter guidelines.

Hey there, in Ontario, Canada our standards state that for open wounds they should be prepped using normal saline.

I've only ever seen one doc prep open wounds, and he uses a 50/50 mixture of betadine paint and saline. But I am not sure of the rationale.

Safe to go with manufacturer's guideline and read the inserts...hospital policy as well and based on those make your decision.

Just had an inservice from the Chloraprep rep. She says unless it is necrotic, Chloraprep stays off open wounds. It can inhibit new tissue growth. You can ask your rep to bring or email you research.
