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.

Conditions

Uterine Contractions; Delivery

Keywords

Uterine contraction;; Shape; Frequency;; First stage labor;; Fall; Rise ratio.

Outcome Measures

Primary Outcomes (1)

• the shape and frequency of uterine contractions

  Uterus contractions were recorded using electronic fetal monitoring at the beginning of the active phase of labor (dilatation 3-5 cm) for 30 min.

  up to 15 months

Study Arms (2)

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.
