Group Intervention Description TVCL-based Transvaginal ultrasound Monitor progression of labor by shortening of cervix examined by transvaginal cervical length Conventional-based Transvaginal ultrasound Monitor progression of labor by per vaginal exam to detect cervical change
- Primary Outcome Measures
Name Time Method Number of cases with delivery within 7 day after admission From admission to no uterine contraction in 10 minute In case of threatened preterm labor if detection the progression of labor by transvaginal cervical length, the rate of delivery within 7 days will less or more than conventional group.
- Secondary Outcome Measures
Name Time Method The number of tocolysis courses, length of hospital stay From admission to no uterine contraction in 10 minute In case of tocolytic used for stop labor. The number of medication will be recorded.
The number of steroid courses From admission to no uterine contraction in 10 minute In case of stop labor, the course of steroid for promote lung maturity is recorded.
