Minimal antibiotic therapy after emergency abdominal surgery: a prospective study

Area of Science:

• Surgical Infections
• Antibiotic Stewardship
• Clinical Outcomes

Background:

• Postoperative antibiotic duration after emergency abdominal surgery lacks standardized guidelines.
• Current practices often involve prolonged antibiotic courses, potentially contributing to resistance.
• Optimizing antibiotic therapy is crucial for patient recovery and resource management.

Purpose of the Study:

• To determine the optimal duration of postoperative antibiotic therapy following emergency abdominal surgery.
• To evaluate the impact of a tailored antibiotic strategy based on intraoperative findings.
• To assess the safety and efficacy of a 'minimal' antibiotic policy.

Main Methods:

• A prospective study involving 163 patients undergoing emergency abdominal surgery.
• Patients were stratified into four groups based on postoperative antibiotic duration: none, 24 hours, 48 hours, and 72 hours to 5 days.
• Antibiotic administration was guided by operative findings of contamination and infection severity.

Main Results:

• Overall mortality was 2% (3 patients).
• Surgical site infections occurred in 7% (12 patients), and intra-abdominal infections in 1% (2 patients).
• A 'minimal' antibiotic policy, guided by operative stratification, proved successful in managing infections.

Conclusions:

• Tailoring antibiotic duration based on intraoperative contamination and infection severity is feasible and effective.
• A 'minimal' postoperative antibiotic strategy can achieve favorable outcomes in emergency abdominal surgery.
• Further research may support shorter, targeted antibiotic courses to optimize patient care and combat resistance.
