[Surgical site infection: risk factors, prevention, diagnosis and treatment]

Area of Science:

• Infectious Diseases
• Surgical Infections
• Microbiology

Context:

• Surgical site infections (SSIs) are a significant concern in healthcare settings.
• Understanding the sources and risk factors for SSIs is crucial for prevention and management.
• The spectrum of SSIs ranges from superficial cutaneous infections to deep infections involving body cavities.

Purpose:

• To outline the etiology, risk factors, and management strategies for surgical site infections.
• To differentiate between superficial and deep SSIs and their respective treatment approaches.
• To emphasize the importance of avoiding empiric antibiotic therapy in specific SSI cases.

Summary:

• SSIs involve contamination of surgical wounds by endogenous microbial flora.
• Infection risk is multifactorial, including bacterial load, patient health, and surgical procedure details.
• Superficial SSIs are managed locally, while deep SSIs, particularly those with foreign material, require aggressive surgical debridement and specific antimicrobial treatment.
• Empiric antibiotic therapy is contraindicated in cases with foreign material due to potential complications.

Impact:

• Improved understanding of SSI pathogenesis and risk stratification.
• Guidance on appropriate treatment strategies, emphasizing debridement and targeted therapy.
• Reduced incidence of complications associated with inappropriate antibiotic use in SSIs.
• Enhanced patient outcomes through effective management of surgical wound infections.
