Brief summary
This pilot randomized controlled trial evaluates the feasibility, tolerability, and preliminary efficacy of a decolonization regimen using polyhexanide in reducing Staphylococcus aureus colonization in the preoperative phase of elective spine surgery, compared to the standard mupirocin and chlorhexidine regimen. The trial involves 24 participants randomized into two groups: one receiving polyhexanide and the other receiving mupirocin and chlorhexidine. The primary outcome is the randomization rate, with secondary outcomes including other feasibility outcomes, tolerability, and efficacy measures such as the reduction in S. aureus colony-forming units (CFUs) and changes in the nasal and skin microbiome composition.
Interventions
Participants will apply Prontoderm® Nasal Gel and perform whole-body wash with Prontoderm® Foam daily for 5 days before surgery.
Participants will apply Bactroban® Nasal ointment and perform whole-body wash with Lifo-Scrub® daily for 5 days before surgery.
