摘　　要：目的 探讨超声测量孕妇骨盆入口前后径的方法及临床价值。方法 将200例单胎孕37-42周的孕妇于产前1～3d行超声检查，测量孕妇骨盆入口前后径、胎儿双顶径、胎儿单侧锁骨长等参数，并与剖宫产术中测量的骨盆入口前后径、生后24h测量的新生儿双顶径、单侧锁骨长相比较。结果 骨盆入口前后径、胎儿双顶径、单侧锁骨长等参数的超声测值与实际测值有良好的临床符合性；当骨盆入口前后径与胎儿双顶径的差值〈2．1cm时剖宫产的发生率增加。结论 超声测量孕妇骨盆入口前后径方法简单、准确，对母儿无害，在测量骨盆径线的同时能了解胎先露、胎方位等与分娩密切相关的因素，有助于产科工作者综合考虑，决定分娩方式。Objective To evaluate the methods and predictive values of obstetric conjugata measured by ultrasound. Methods A total of 200 women at 37-42 week＇s gestation,delivering a singleton infant and having an ultrasound examination within three days before delivery were studied. The obstetric conjugata,fetal biparietal diameter（BPD）, fetal clavicula were measured by ultrasound, and compared with the obstetric conjugata measured in operation,newborn BPD,and newborn clavicula. Results The parameters such as obstetric conjugata,BPD and clavicula had no significant difference between ultrasonic measurement and actual measurement. When the obstetric conjugata and BPD difference （2.1 cm, the happenness of operation delivery increased. Conclusions The method measuring conjugata of the pelvic inlet is accurate and simple, and it is harmless to mater and fetus. At the same time it could realize the factors correlated with delivery such as fetal presentation and fetal position, which would help the obstetrician to consider synthetically and decide the partal mode accurately.
