We are using Chloraprep as well. Interestingly, since switching from DuraPrep, we have had only one infection in i believe 9 months. It was right after we made the switch. Also, our infection control manager mandated the switch which didnt sit well with some of the docs. Alot of the ortho docs were set on using Duraprep and the ioban, but when Robin-icp- provided the evidence that the impregnated drapes had no effect on infection and the chloroprep was more effective than duraprep they accepted the change. the new AORN guidelines have a nice table on preps as well. -T
