Enrollment: 25
Study Start Date: October 2007
Study Completion Date: February 2008
Primary Completion Date: February 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Chlorhexidine gluconate 2%
Drug: Chlorhexidine gluconate
Chlorhexidine gluconate (2% w/v) in an aqueous base. Administered topically.
Other Name: ChloraPrep AQ
Active Comparator: 2
Povidone iodine scrub and paint
Drug: Povidone iodine
Povidone iodine scrub and paint. Administer topically.
Other Name: Betadine

Detailed Description:

Evaluate the effect of application procedure on the antimicrobial properties of a new product and a currently marketed product. Study will be conducted using methods dictated by the FDA.

Study uses topical sampling from the abdomen and groin on intact skin and evaluates the germs. Effects of blotting versus not blotting will be assessed.
