Skin and Nasal Antiseptic from 3M Clinical studies show that this nasal prep, packaged in a 4mL bottle with swabs, kills 99.5% of Staphylococcus aureus, including MRSA, in the nares in 1 hour and maintains that level for at least 12 hours, a key benefit for surgical patients who may be at risk for infection, says the company. The povidone-iodine solution consists of film-forming materials so that the active ingredient remains in the nares, coating and adhering to the mucosal tissue where bacteria reside, says the company. "This is especially important because the unique physiology of the nose presents many challenges not seen on the skin," says 3M. "The nose works continuously to clear foreign particles and microorganisms, making it difficult for antimicrobials to reach and kill bacteria." www.3M.com/infectionprevention
