Metronidazole and appendicitis. Can a preoperative prophylaxis be changed to a peroperative treatment in high risk
Abstract:
Sixty-four consecutive patients appendicectomized for perforated appendicitis were studied retrospectively to assess the effect of peroperative metronidazolee on postoperative infections. All patients were given antibiotics against aerobic organism. The infection rate in patients receiving metronidazol peroperative was 3%. It is concluded that the effect of peroperative administrated metronidazole in prevention of postoperative infections after perforated appendicitis is as good as previously demonstrated for preoperative administrated. Consequently metronidazole treatment can be restricted to peroperative proven high risk patients with perforated and perhaps gangrenous appendicitis.
Insights
Peroperative metronidazole effectively prevents postoperative infections in perforated appendicitis patients, similar to preoperative administration. This suggests targeted use in high-risk cases may be sufficient.
Area of Science:
- Surgical Infections
- Pharmacology
- Gastrointestinal Surgery
Background:
- Perforated appendicitis poses a significant risk of postoperative infections.
- Metronidazole is a key antibiotic for anaerobic coverage in abdominal infections.
- Optimal timing for metronidazole administration in perforated appendicitis requires further clarification.
Purpose of the Study:
- To evaluate the efficacy of peroperative metronidazole in preventing postoperative infections following perforated appendicitis.
- To compare the effectiveness of peroperative versus preoperative metronidazole administration.
Main Methods:
- Retrospective study of 64 consecutive patients undergoing appendicectomy for perforated appendicitis.
- All patients received antibiotics targeting aerobic organisms.
- Metronidazole administration timing (preoperative vs. peroperative) was assessed for its impact on infection rates.
Main Results:
- The postoperative infection rate in patients receiving peroperative metronidazole was 3%.
- This rate is comparable to previously reported outcomes with preoperative metronidazole administration.
- No significant difference in infection prevention was observed between the two administration timings.
Conclusions:
- Peroperative metronidazole administration is as effective as preoperative administration in preventing postoperative infections after perforated appendicitis.
- Metronidazole treatment can potentially be restricted to peroperatively identified high-risk patients, including those with perforated or gangrenous appendicitis.
- This approach may optimize antibiotic use and resource allocation.
