New triple clean routine slashes shoulder surgery infection risk
NCT ID NCT05701475
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding a benzoyl peroxide gel before surgery to the usual iodine cleaning could lower the chance of infection from Cutibacterium acnes bacteria during shoulder surgery. 156 adults scheduled for shoulder surgery were split into three groups: standard iodine cleaning, iodine cleaning of skin and deeper layers, or the triple method with benzoyl peroxide plus iodine. The researchers took bacterial samples during surgery to compare infection rates between the groups.
