| 目的 探讨胎儿体质量对经阴道分娩初产妇盆膈裂孔形态学的影响。方法 根据新生儿出生时体质量,将50名单胎阴道分娩的产后初产妇分为产后正常儿组(2500~3999 g)35名和产后巨大儿组(≥4000 g)15名。同期选取健康未育女性35名作为对照组。行经会阴三维超声检查,采集盆膈裂孔声像图,观察并测量静息期、缩肛期和张力期盆膈裂孔的形态及参数。结果 产后巨大儿组产妇盆膈裂孔变形发生率[66.67%(10/15)]高于产后正常儿组[31.43%(11/35)],差异有统计学意义(χ2＝5.352,P＝0.021)。产后正常儿组静息期、张力期和缩肛期盆膈裂孔的前后径(t=4.409、5.108、2.925)、左右径(t=2.342、2.167、2.242)及面积(t=6.613、5.314、4.967)均大于对照组(P均< 0.05)。产后巨大儿组静息期、张力期和缩肛期盆膈裂孔的前后径(t=5.753、4.548、5.103)、左右径(t=5.527、4.311、4.299)及面积(t=9.265、4.179、10.563)均大于对照组(P均< 0.05);且静息期、张力期和缩肛期盆膈裂孔的前后径(t=3.037、2.423、2.152)、左右径(t=2.388、2.866、2.432)及面积(t=5.323、9.607、5.024)均大于产后正常儿组(P均< 0.05)。结论 通过三维超声可有效评价胎儿体质量对阴道分娩初产妇盆膈裂孔的影响。妊娠和分娩巨大儿更易造成产妇盆膈裂孔形态与大小的改变。 |

| Objective To explore the morphology impact on pelvic hiatus by fetal weight in vaginal delivery primipara. Methods A total of 50 primiparous women were divided into postnatal normal group (2500—3999 g, n=35) and postnatal macrosomia group (≥4000 g, n=15) according to the birth weight of newborn. Meanwhile, the control group of 35 healthy nulliparous women were enrolled. Translabial three-dimensional ultrasound was performed to observe the morphology and measure the parameters of pelvic hiatus at resting, pelvicmuscle contraction and during maximum valsalva maneuver. Results The incidence of primipara pelvic hiatus deformation in postnatal macrosomia group (66.67%[10/15]) was higher than that in postnatal normal group (31.43%[11/35], χ2＝5.352, P＝0.021). The anteroposterior diameters (t=4.409, 5.108, 2.925), left to right diameters (t=2.342, 2.167, 2.242) and areas (t=6.613, 5.314, 4.967) of pelvic hiatus at resting, during maximum valsalva maneuver and pelvicmuscle contraction in postnatal normal group were larger than those in control group (all P< 0.05). And the anteroposterior diameters (t=5.753, 4.548, 5.103), left to right diameters (t=5.527, 4.311, 4.299) and areas (t=9.265, 4.179, 10.563) of pelvic hiatus at resting, during maximum valsalva maneuver and pelvicmuscle contraction in postnatal macrosomia group were also larger than those in control group (all P< 0.05). While the anteroposterior diameters (t=3.037, 2.423, 2.152), left to right diameters (t=2.388, 2.866, 2.432) and areas (t=5.323, 9.607, 5.024) of postnatal macrosomia group were larger than those of postnatal normal group at resting, during maximum valsalva maneuver and pelvicmuscle contraction (all P< 0.05). Conclusion Using three-dimensional ultrasound can evaluate the morphology impact of pelvic hiatus in vaginal delivery primipara caused by newborn birth weight effectively. Pregnancy and macrosomia are more likely to cause the shape and size changes of pelvic hiatus. |
