简要总结
Acidification of vaginal pH has been proposed as a potential factor that could help increase the efficacy of vaginal prostaglandins in labor induction. The aim of the present randomized controlled trial is to evaluate the impact of an acidic vaginal pH on the progress of labor induction with dinoprostone (Prostaglandin E2 - PGE2) vaginal tablet.

盲法说明
Randomization will be computer generated. Allocation concealment will be ensured by opaque sealed envelopes. Blinding of outcomes assessor, principal as well as other investigators will be ensured as randomization will be performed by an external investigator that will not participate in the clinical process of the study or the statistical analysis. The ward midwife will open the randomization envelope after patient enrollment and different types of vaginal washing will be applied as per randomization. Participant as well outcomes assessor (physician that will evaluate the progress of labor as well statistician involved in the analysis) will be blinded to the procedure.
