近十五年中,分娩期的处理发生了许多变化,包括胎儿电子监护的出现,中位产钳助产的下降,较少依赖盆腔X线测量术。相伴出现的是剖腹产率增加了3倍,大约有三分之一是由于难产(如分娩进展异常)。所以显然需要改变难产的处理方法。注意到作者所在医院难产剖腹产率不到美国国家资料剖腹产率的一半,促使作者更详细地评价对产程异常的处理。鉴于作者对产程异常很少采用剖腹产或中位产钳,故将这些处理称作药物性处理。
In the last fifteen years, many changes have taken place in the delivery period, including the emergence of fetal electronic monitoring, the reduction of midwifery midwifery, and less dependence on pelvic X-ray. Concomitantly there is a threefold increase in caesarean section rates, with about one third due to dystocia (such as abnormal delivery progress). So clearly need to change the treatment of dystocia. Noting that the authors’ hospital-based hospital dystocia rate was less than half that of the US national data C-section, prompted the author to evaluate in more detail the management of labor abnormalities. Given that the authors seldom adopt caesarean sections or midline forceps for anomalous labor, these treatments are referred to as pharmacological treatments.
