Literature review was performed to analyze and define the current state of operative vaginal delivery. On the basis of published data, it is concluded that outlet and low forceps deliveries with < or = 45 degrees of rotation are effective and safe for both mother and baby. The greatest risk to mother or fetus occurs with operations performed at the 0 or +1 station or those involving rotations > 45 degrees. It is likely that operative deliveries involving > 45 degrees of rotation will be abandoned in the future. It is further recommended that The American College of Obstetricians and Gynecologists 1988 forceps classification system be adopted for deliveries by vacuum extractors.
进行文献综述以分析和界定手术阴道分娩的现状。根据已发表的数据得出结论，旋转角度≤45度的出口产钳和低位产钳分娩对母婴均有效且安全。在0或+1水平进行的手术或旋转角度＞45度的手术，对母亲或胎儿的风险最大。未来，旋转角度＞45度的手术分娩很可能会被摒弃。还建议在使用真空吸引器分娩时采用美国妇产科医师学会1988年的产钳分类系统。
