[Progress in the treatment of intra-abdominal anaerobic infection]

Area of Science:

• Microbiology
• Infectious Diseases
• Surgical Infections

Background:

• Abdominal infections are frequently polymicrobial, involving aerobic and anaerobic bacteria.
• Anaerobic infections present with characteristic signs like rancid secretions and abscesses.
• Effective management hinges on early source control and appropriate antimicrobial strategies.

Purpose of the Study:

• To outline key principles in managing abdominal anaerobic infections.
• To discuss current therapeutic options and challenges.
• To emphasize the importance of rational antibiotic selection based on resistance data.

Main Methods:

• Review of current literature on abdominal infections and anaerobic bacteria.
• Analysis of diagnostic challenges associated with anaerobic cultures and sensitivity testing.
• Evaluation of empirical and targeted antimicrobial treatment strategies.

Main Results:

• Early surgical source control and damage control principles are vital.
• Empirical antibiotic therapy is common due to diagnostic limitations.
• First-line monotherapy options include ertapenem, moxifloxacin, and cefoperazone-sulbactam.
• Combination therapies involve cephalosporins, quinolones, and nitroimidazoles.
• Nutritional and anti-shock support are essential adjuncts.

Conclusions:

• Management requires a multi-faceted approach including surgery, antibiotics, and supportive care.
• Increasing antibiotic resistance necessitates rational prescribing based on local epidemiology.
• Antibiotic stewardship is critical to combat rising resistance rates in anaerobic infections.
