Prophylactic and antimicrobial therapy using lincomycin in patients undergoing emergency caesarean section
Summary
Prophylactic lincomycin or metronidazole significantly reduced anaerobic vaginal carriage and postoperative wound infections in women undergoing emergency surgery. Both antibiotics proved effective in preventing infection compared to placebo.
Area of Science:
- Microbiology
- Infectious Diseases
- Surgical Infections
Background:
- Anaerobic bacteria are common vaginal flora.
- Postoperative wound infections are a significant complication in surgery.
- Emergency surgery patients may have increased risk.
Purpose of the Study:
- To evaluate the efficacy of prophylactic lincomycin and metronidazole.
- To assess the impact on vaginal anaerobic carriage rates.
- To determine the effect on postoperative wound infection development.
Main Methods:
- A study involving 60 women undergoing emergency surgery.
- Three groups: lincomycin prophylaxis (20 patients), metronidazole prophylaxis (20 patients), and placebo (20 patients).
- Vaginal swabs collected pre-operatively and on postoperative days 3 and 5 to assess anaerobic carriage rates.
Main Results:
- Lincomycin and metronidazole reduced vaginal anaerobic carriage from 85% pre-operatively to 20% postoperatively.
- The placebo group showed minimal reduction in anaerobic carriage (100% pre-op, 75% day 3, 80% day 5).
- Wound infections occurred in 6 placebo patients versus 1 each in the lincomycin and metronidazole groups.
Conclusions:
- Prophylactic lincomycin and metronidazole are effective in reducing vaginal anaerobic carriage.
- Antimicrobial prophylaxis with these agents significantly lowers the incidence of postoperative wound infections.
- These findings support the use of lincomycin or metronidazole for infection prevention in emergency surgery.
