Comparing the Shape and Frequency of Uterine Contractions

July 24, 2012 updated by: Samira Ebrahimzadeh Zagami, Mashhad University of Medical Sciences

Principle Investigator

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.

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.
