Summary
Short-term antimicrobial prophylaxis (24 hours) is as effective as long-term prophylaxis (72 hours) in preventing surgical site infections (SSI) after abdominal surgery. This finding supports the use of shorter antibiotic durations for better rationality and cost-effectiveness.
Area of Science:
- Infectious Diseases
- Surgical Infections
- Antimicrobial Stewardship
Context:
- Surgical site infections (SSI) are a significant concern following abdominal operations.
- Antimicrobial prophylaxis is standard practice to prevent SSIs.
- The optimal duration of antimicrobial prophylaxis remains a subject of investigation.
Purpose:
- To compare the efficacy of short-term (24-hour) versus long-term (72-hour) antimicrobial prophylaxis in preventing SSIs.
- To assess the impact of prophylaxis duration on SSI rates in patients undergoing abdominal surgery.
Summary:
- A randomized trial involving 731 patients undergoing abdominal surgery compared 24-hour prophylaxis with 72-hour prophylaxis.
- SSI rates were 0.84% in the short-term group and 2.68% in the long-term group (P > 0.05).
- Netilmicin, alone or with metronidazole, was used for prophylaxis.
Impact:
- Short-term antimicrobial prophylaxis is effective in preventing post-operative SSIs.
- Extended-duration prophylaxis (72 hours) offers no additional benefit over short-term prophylaxis.
- These findings support the use of shorter, more rational, and pharmacoeconomically sound antimicrobial prophylaxis regimens.
