[Main principles of antibiotic prophylaxis and antibacterial therapy in abdominal surgery]

Area of Science:

• Infectious Diseases
• Surgical Oncology
• Pharmacology

Context:

• Intra-abdominal infections pose significant challenges in surgical settings.
• Optimizing antibiotic therapy is crucial for patient recovery and reducing healthcare costs.
• Understanding pathogen dynamics and host response is key to effective treatment strategies.

Purpose:

• To review principles of antibiotic prophylaxis and therapy in abdominal surgery.
• To identify common pathogens, cost-saving measures, and novel therapeutic approaches.
• To explore the role of immunocorrection and targeted antibiotic delivery.

Summary:

• Discusses common pathogens in intra-abdominal infections and strategies to reduce antibiotic therapy expenses.
• Highlights new approaches including immunocorrection and targeted antibiotic transport.
• Examines empirical and etiotropic treatment based on pathogen prevalence and antibiotic sensitivity.
• Correlates Interleukin-1beta and Tumor Necrosis Factor-alpha levels with patient severity, ineffective therapy, and mortality risk.
• Investigates the influence of microorganisms and antibiotics on interferon induction, noting Amoxicillin, Polymyxin, Vancomycin, Cephalosporins, and Fluconazole as active gamma-interferon inducers.
• Emphasizes that maximal efficacy of antibacterial therapy is contingent upon adequate surgical intervention.

Impact:

• Provides insights into managing nosocomial infections in abdominal surgery.
• Suggests biomarkers (cytokines) for predicting treatment outcomes and mortality.
• Identifies specific antibiotics that induce gamma-interferon, potentially aiding therapeutic choices.
• Underscores the critical synergy between surgical intervention and antibiotic therapy for optimal results.
