目的探讨母体骨盆出口径线参数预测在头位难产中的应用。方法随机选取我院妇产科56例诊断为头位难产的孕产妇为实验组,同时选取同期在我科治疗的56例自然分娩的孕产妇为对照组,分别测量2组的骶耻外径、对角径、坐骨结节间径及后矢状径、出口前后径、耻骨联合长度等骨盆径线,分析2组患者各种径线存在的差异。结果实验组的骶耻外径、对角径、坐骨结节间径及坐骨结节间径+后矢状径、出口前后径、耻骨联合长度与对照组比较,均有统计学差异(P均<0.01),后3种径线变化更明显。结论头位难产患者骶耻外径、对角径、坐骨结节间径及坐骨结节间径+后矢状径、出口前后径、耻骨联合长度均有所减小,但是坐骨结节间径+后矢状径、出口前后径、耻骨联合长度的径线长度变化更有助于对头位难产的判断。
Objective To explore the application of prediction of diameter parameters of maternal pelvis in dystocia with head position. Methods 56 cases of gynecological obstetrics and gynecology in our hospital were randomly selected as the experimental group. Fifty-six pregnant women with spontaneous labor who were treated in our department at the same period were selected as the control group. , The diameter of the ischial tuberosity, the diameter of the ischial tuberosity and sagittal diameter, the anteroposterior diameter of the outlet, the length of the pubic symphysis and other pelvic diameter. The differences of the diameters of the various diameters of the two groups were analyzed. Results There were significant differences in the external diameter, diagonal diameter, the diameter of the ischial tuberosity, the diameter of the ischial tuberosity, the sagittal diameter, the anteroposterior diameter and the length of the pubic symphysis between the experimental group and the control group (P <0.01), after three kinds of diameter changes more obvious. CONCLUSIONS: Sacral external diameter, diagonal diameter, ischial tuberosity, ischial nodule diameter, posterior sagittal diameter, anteroposterior diameter and pubic symphysis length of head dystocia patients decreased, but the diameter of ischial tuberosity + Sagittal diameter, anteroposterior diameter, pubic symphysis length of the radial length of the change is more conducive to the first bit of labor judgment.
