First received: March 17, 2011
Last updated: December 8, 2013
Last verified: December 2013
The purpose of this study is to compare Bishop score, sonographic cervical length and multiple proteins in cervicovaginal fluid at 40 weeks gestation to predict time to spontaneous labor and mode of delivery.

Condition Intervention
Prolonged Labor
Other: Ultrasound and digital cervical examination

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Further study details as provided by Seoul National University Hospital:

Primary Outcome Measures:
  • Onset of labor/delivery ≤10days [ Time Frame: Baseline ]

Secondary Outcome Measures:
  • Cesarean delivery in labor [ Time Frame: Baseline ]
    1. Time to onset of spontaneous labor
    2. Postterm delivery (≥40 + 11 weeks of pregnancy)
    3. The rate of cesarean delivery

Biospecimen Retention:   Samples Without DNA
