摘要： 目的：观察经会阴超声检查仪监测产程进展角（angle of progression，AOP）和大脑中线角（midline angle，MLA）在产程进展中的变化及临床意义。方法：对足月、单胎、头位分娩的97例产妇，在进入产程后用经会阴超声检查仪在宫口开大2～3 cm、4～5 cm、7～8 cm、9～10 cm测量AOP和MLA，并分析两者之间的相关性。结果：随着产程进展、宫口的开大，AOP逐渐增大，MLA逐渐减小，且两者呈负相关。结论：经会阴超声可以应用于产程监测，并发挥其无创、方便、减少感染、可重复的优势。

Abstract: Objective：To observe the variation and clinical significance of the angle of progression（AOP） and the midline angle（MLA） in stage of labor. Methods：Transperineal ultrasound were performed in 97 single cephalic term pregnancies. AOP and MLA were performed when the cervix enlarged at 2-3 cm，4-5 cm，7-8 cm and 9-10 cm. We analyzed the relationship between AOP and MLA. Results：Along with the birth process, the AOP is gradually increasing while the MLA is reduced gradually. There was a negative correlation between AOP and MLA. Conclusions：The transperineal ultrasound can be used in monitoring of the stages of labor，and exploite the advantages of noninvasiveness，convenience，reduce infection and repeatability.
