Efficacy and safety of two antibacterial treatments (Polyhexanide versus Mupirocin/Chlorhexidine) prior to a planned spinal surgery: A randomized controlled pilot trial
Zusammenfassung der Studie
Staphylococcus aureus is a skin bacterium and an important pathogen. It is particularly common in surgical site infections (SSIs). Spinal surgeries have been shown to have a high SSI rate. Such infections not only lead to prolonged hospital stays and increased healthcare costs but also pose a significant threat to patient recovery and outcomes. Approximately 20-30% of the general population are nasal carriers of S. aureus, with higher rates often observed in healthcare settings and among certain patient groups. In patients with spinal cord injuries, the risk is even greater, making prevention even more critical. Combating colonization with S. aureus, especially prior to spinal surgeries, represents an urgent, only partially met need in the medical community. While nasal decolonization with Mupirocin and skin decolonization with Chlorhexidine gluconate (CHX) have been the cornerstones of strategies to prevent S. aureus infections in surgical patients, the emergence of bacterial resistance underscores the need for alternative approaches. The increasing resistance to Mupirocin, associated with failures in decolonization at high concentrations, necessitates urgent research into new decolonization agents. The research work we propose addresses this challenge and focuses on Polyhexanide, a broad-spectrum disinfectant that has proven to be a promising candidate. Its action against the bacterial cell wall represents a different mechanism than that of Mupirocin and could provide a solution to the resistance problem.

Untersuchte Intervention
In our study, participants are randomly assigned to groups. This is important to obtain reliable results from the study. This is called randomization. Each group receives a different treatment. In our study, there are two groups:
• Group 1 (experimental group): application of Polyhexanide nasal ointment twice daily and Polyhexanide whole-body wash once daily for 5 days prior to surgery.
• Group 2 (control group): application of Mupirocin nasal ointment twice daily and Chlorhexidine whole-body wash once daily for 5 days prior to surgery.
