Background:
Surgeons managing intra-abdominal infections should always respect the basic principles of antibiotic treatment. An adequate duration of antimicrobial therapy is important to optimize empiric therapy and minimize selective pressures favoring antimicrobial resistance.
Methods:
The optimal duration of antibiotic therapy for intra-abdominal infections (IAIs) has been debated in the last years. A literature research, based on PubMed database and limited to English language publications, was performed without restriction of time or type of manuscript.
Results:
In stable patients a short course of antimicrobial therapy (3-5 d) after adequate source control, depending on fever and leukocytosis, may be a reasonable option. In critically ill patients with severe sepsis and septic shock, an individualized approach is always mandatory and patient's inflammatory response should be monitored regularly. Procalcitonin may be helpful for guiding antibiotic treatment in critically ill surgical patients and in predicting treatment response.
Conclusions:
General surgeons managing intra-abdominal infections should always respect the basic principles of antibiotic treatment. Duration of antimicrobial treatment is an important variable to evaluate in treating complicated intra-abdominal infections.
Insights
For intra-abdominal infections, a short antibiotic course (3-5 days) may suffice for stable patients after source control. Critically ill patients require individualized treatment, with procalcitonin aiding antibiotic guidance and response prediction.
Area of Science:
- Infectious Diseases
- Surgical Infections
- Antimicrobial Stewardship
Background:
- Optimal antibiotic duration for intra-abdominal infections (IAIs) is crucial for effective treatment and minimizing antimicrobial resistance.
- Basic principles of antibiotic therapy must be followed in managing IAIs.
Purpose of the Study:
- To review the optimal duration of antibiotic therapy for intra-abdominal infections.
- To provide guidance on antibiotic treatment duration based on patient condition.
Main Methods:
- Literature search of the PubMed database for English language publications.
- No restrictions on publication time or manuscript type.
Main Results:
- Stable patients may benefit from a short course (3-5 days) of antibiotics post-source control, contingent on fever and leukocytosis.
- Critically ill patients necessitate an individualized approach with regular monitoring of inflammatory response.
- Procalcitonin can assist in guiding antibiotic therapy and predicting treatment outcomes in critically ill surgical patients.
Conclusions:
- General surgeons must adhere to fundamental antibiotic treatment principles for IAIs.
- Duration of antimicrobial therapy is a key factor in managing complicated intra-abdominal infections.
