简要总结
In primigravida, Delayed engagement of fetal head has been theorized that it is more likely in women with a possible cephalo-pelvic disproportion, so far they are associated with higher risk of cervical dystocia, which led to increased rate of caesarean section.
详细描述
This study will involve total 226 of " 113 primigravida patients with engaged head and 113 primigravida patients with unengaged head .
while assessment of fetal head station, status of membrane should be evaluated and noted.
Engagement will be assessed by vaginal examination as described by Müller in 1868 , assumes that when the leading edge of the vertex is felt at the level of the ischial spines, the biparietal diameter will have just passed through the pelvic brim. The leading edge of the vertex at the level of the ischial spines is designated as being at station 0. If the leading edge is 1 cm below the level of the spines, this is referred to as station +1. Usually, a head on the pelvic floor is at station +4 or +5.
Uengaged head is still 2 cm above the level of the spines is at station -2, and so on.
The aim of this study will be to determine if primigravida patients with unengaged head after spontaneous onset of labor are at increased risk of cesarean section.
