Hypothesis
What are the bacterial types and colony counts present before and during vaginal surgery?
Conclusion
Future interventions to reduce bacterial colony counts should focus on the first 30 to 90 minutes of surgery.
Supporting Evidence
- 52% of surgical fields were contaminated 30 minutes after the surgical scrub.
- 41% of cultures were contaminated 90 minutes after the surgical scrub.
- None of the 31 patients developed operative site infections.
Takeaway
Doctors found a lot of bacteria in the vagina during surgery, especially right after they cleaned it. They think they need to do something different in the first hour to keep it cleaner.
Methodology
Descriptive study with aerobic and anaerobic cultures taken before and during vaginal surgery.
Limitations
The study was a pilot and did not perform group comparisons.
Participant Demographics
Patients aged 26 to 82 years, with a mean age of 51 years; 81% Caucasian, 19% African-American; 48% postmenopausal.
Statistical Information
Confidence Interval
95% confidence intervals reported for total and anaerobic colony counts.
