Brief Summary:
Dystocia is the most common indication for primary cesarean section. The most common cause of dystocia is uterine dysfunction. In all cephalopelvic disproportion studies, more attention is usually paid on fetus and pelvic rather than on the role of uterine contraction in delivery. So we decided to determine the relationship between dystocia and uterine contraction patterns.

Uterine Contractions Delivery

Study Type : Observational
Actual Enrollment : 95 participants
Time Perspective: Prospective
Official Title: Principle Investigator
Study Start Date : April 2010
Actual Primary Completion Date : June 2011
Actual Study Completion Date : July 2011

Group/Cohort
the shape and frequency of uterine contractions in delivery
Uterine contractions were recorded by using fetal monitoring system (Model FC1400) at the beginning of the active phase (cervical dilatation 3-4 cm) for 30 min in two groups.
the shape and frequency of uterine contractions in cesarean
Uterine contractions were recorded by using fetal monitoring system (Model FC1400) at the beginning of the active phase (cervical dilatation 3-4 cm) for 30 min in two groups.



Primary Outcome Measures :
  1. the shape and frequency of uterine contractions [ Time Frame: up to 15 months ]
    Uterus contractions were recorded using electronic fetal monitoring at the beginning of the active phase of labor (dilatation 3-5 cm) for 30 min.
