宫口扩张

影响头位分娩的诸因素中先露下降、宫口扩张、胎位、宫缩强度、活跃期长短与难产相关性较大；

Delivery factors such as descent of fetal presentation , dilatation of cervix , fetal position , strength of uterine contraction , length of active phase were more closely related with dystocia .

结论潜伏期宫颈局部注射或/和静脉注射间苯三酚对加速宫口扩张、缩短产程、降低难产率有一定的临床意义。

Conclusions Cervical injection of Phloroglucinol during latent phase has clinical significance in accelerating cervical dilatation , shortening the labor and reducing the incidence of dystocia .

观察组除临产后在宫口扩张2～4cm时行双扩法气囊助产术外，其它产科处理措施与对照组相同。

The gasbag group was given the same obstetrical treatments as that in the control group , but gasbag midwifery skill was used twice when the cervix was dilated 2cm ~ 4cm in labor .
