Benzoyl Peroxide and Electrocautery Skin Inicision to Eradicate Cutibacterium Acnes

• Status: Not yet recruiting
• Trial end date: 2024-08-30
• Target enrollment: 0
• Participant gender: Male

Summary

The goal of this prospective randomized clinical trial is to investigate the potential synergistic effect of combination of topical benzoyl peroxide and making skin incision with electrocautery on preventing surgical wound contamination from Cutibacterium acnes (C. acnes) in patients undergoing shoulder replacement.

The main question it aims to answer is:

• Will the combined use of topical application of benzoyl peroxide and making skin incision using electrocautery decrease the positive culture rates of C. acnes in the surgical field?

Participants will be asked to apply topical benzoyl peroxide to the shoulder skin prior to their shoulder replacement surgery if they are randomized in the treatment group. The skin incision will be made using electrocautery in both the control and treatment groups. Microbiology swab cultures will be taken during shoulder replacement surgery to compare the positive culture rates for C. acnes between the groups.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No
