为使头位难产通过手法旋转，使不正常的胎头位置变为正常的胎头位置通过产道，使难产变为正常产， 降低手术产率，对徒手纠正异常胎头位置３６６例进行临床分析。结果：①３６６例头位难产通过手法纠正不正常的胎头位 置，成功３３２例，成功率９０．７１％；②一旦徒手旋转成功，都可以经阴道分娩；③正确估计胎儿体重，如胎儿体重超过４ ０００ ｇ，手法纠正较困难。徒手纠正异常胎头位置是降低头位难产的一种简便有效的方法。
In order to make the first bit of dystocia by means of rotation, so that abnormal fetal head position into a normal fetal head position through the birth canal, so that dystocia to normal production, reduce surgical yield, to correct the abnormal position of 366 cases of fetal head abnormalities for clinical analysis . Results: ①366 cases of head dystocia corrected abnormal fetal head position, 332 cases were successful, the success rate was 90.71%; ② Once successful hand rotation, can be vaginal delivery; ③ correct estimation of fetal weight, such as fetal weight over 4 000 g, manual correction more difficult. Manual correction of abnormal fetal head position is to reduce head dystocia a simple and effective method.
