Multicentre study of 'Flagyl' in the prevention of post-operative anaerobic infection
Abstract:
In a study carried out with 565 patients undergoing gynaecological and general surgical procedures, metronidazole ('Flagyl') was used pre- and post-operatively and the incidence of post-operative infection, particularly that due to anaerobic organisms, was recorded. This was not a controlled study but, by comparison with other series, it would appear that the use of oral metronidazole had substantially reduced the likelihood of supervention of anaerobic sepsis. It is probable that the use of intravenous metronidazole therapy would have reduced the incidence of anaerobic sepsis still further had this preparation been available at the time.
Insights
Oral metronidazole significantly reduced anaerobic infections in 565 surgical patients. This antibiotic prophylaxis appears effective in preventing post-operative anaerobic sepsis, especially in gynaecological procedures.
Area of Science:
- Surgical infection prevention
- Antimicrobial prophylaxis
- Anaerobic bacterial infections
Background:
- Post-operative infections pose a significant risk in gynaecological and general surgery.
- Anaerobic organisms are common culprits in surgical site infections.
- Metronidazole is a key antibiotic for treating anaerobic infections.
Purpose of the Study:
- To evaluate the efficacy of oral metronidazole in preventing post-operative infections, specifically those caused by anaerobic bacteria.
- To assess the impact of metronidazole prophylaxis on anaerobic sepsis in surgical patients.
Main Methods:
- A study involving 565 patients undergoing gynaecological and general surgical procedures.
- Administration of oral metronidazole pre- and post-operatively.
- Recording the incidence of post-operative infections, with a focus on anaerobic organisms.
Main Results:
- The use of oral metronidazole appeared to substantially reduce the likelihood of anaerobic sepsis.
- While not a controlled study, findings suggest a positive impact on infection rates.
- Comparison with other series indicated a beneficial effect of metronidazole prophylaxis.
Conclusions:
- Oral metronidazole is likely effective in reducing anaerobic post-operative infections in surgical patients.
- Intravenous metronidazole may offer even greater efficacy, though it was not available at the time of the study.
- Metronidazole prophylaxis is a valuable strategy for preventing anaerobic sepsis in surgical settings.
