Objectives: To examine the efficacy of the use of antibiotics in preterm labor (PTL) with intact membranes, after evaluating intra-amniotic microbes by our rapid and bacteria-free polymerase chain reaction (PCR) system.
Materials and methods: One hundred and four PTL patients before 32 weeks of gestation were recruited. Until 2012, antibiotics were empirically prescribed based on the clinical severity of PTL. Intra-amniotic microbes in stored samples were evaluated later by our newly established PCR system, and the efficacy of the use of antibiotics in PTL was evaluated.
Results: In the amniotic fluid (AF) microbe-negative patients (n = 67), antibiotic therapy significantly shortened the gestation period (P < 0.0001), whereas in the microbe-positive patients (n = 37), appropriate antibiotic therapy (proper antibiotic selection against identified AF microbes) was significantly associated with an increase in gestation period (P < 0.0001).
Conclusion: Appropriate antibiotic therapy in PTL with intact membranes prolonged the gestation period.
