  Purpose

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.

Further study details as provided by Mashhad University of Medical Sciences:

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


Enrollment: 95
Study Start Date: April 2010
Study Completion Date: July 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts
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.
