Abstract

Objective To observe pelvic floor muscle′s contraction in women with the second and full term natural parturition by intelligent ultrasonic examination. Methods Ninety-five postpartum women who underwent natural parturition and post-partum check (6-9 weeks after delivery) in Henan Provincal People′s Hospital were recruited in this study from Jul to Dec 2018. Fifty-four puerpera were first parturition and 41 were second parturition. The morphology of urogenital hiatus was observed during both rest and contract maneuver by real-time 3D ultrasound. Several parameters were measured by intelligent ultrasound, such as hiatal area, anteroposterior diameter, transverse diameter, and the thickness of puborectalis muscles, and the D-values of all parameters were calculated in different maneuver. Meanwhile, the strength of pelvic muscle in two groups were measured and the ultrasonic diameters and muscle strength were compared. Results The hiatal area, anteroposterior diameter, transverse diameter, and the thickness of bilateral puborectalis muscles between first natural parturition and second natural parturition during rest maneuver were (15.92±2.76)cm2 vs (16.65±2.63)cm2, (40.93±5.63)mm vs (40.27±6.21)mm, (55.54±6.05)mm vs (57.92±5.27)mm, (7.03±1.51)mm vs (7.44±1.23)mm, (7.49±1.44)mm vs (7.44±1.44)mm, there was no statistical difference(P>0.05). During contract maneuver, these data were (11.76±2.62)cm2 vs (12.09±2.78)cm2, (37.57±5.46)mm vs (37.18±4.71)mm, (42.21±5.69)mm vs (43.03±7.13)mm, (8.92±1.54)mm vs (8.87±1.23)mm, (8.90±1.60)mm vs (9.30±2.71)mm, there was no statistical difference(P>0.05). The D-values of all diameters were (4.16±2.38)cm2 vs (4.43±2.70)cm2, 3(1.00, 5.00)mm vs 1(1.00, 5.25)mm, (13.33±6.07)mm vs (14.41±6.54)mm, (1.90±1.78)mm vs (1.68±1.31)mm, 1(0.48, 2.40)mm vs 1.25(0.20, 2.13)mm, there was no statistically significant difference between two groups (P>0.05). The non-eligibility rate of typeⅠmuscle fiber strength in two groups were 65% vs 68%(35 vs 28) and typeⅡmuscle fiber strength were 74% vs 79%(40 vs 32), there was no statistically difference between two groups (P>0.05). Conclusions In comparison to the primary and full term natural parturition women, there is no significant reduction of the pelvic floor muscle′s contraction by intelligent ultrasund in second and full term natural parturition women without abnormal pregancy history and complications. This could provide theoretical basis for the choice of the mode of second parturition and the rahabilitation of postpartum.

智能超声对二次顺产产妇盆底肌收缩力的观察

目的应用智能超声技术观察自然分娩中期和足月产妇盆底肌收缩情况。方法选择河南省人民医院于2018年7月至12月进行顺产和产后检查的95名产后妇女（产后6-9周）为研究对象。54名产妇为第一次分娩，41名产妇为第二次分娩。通过实时三维超声观察静息和收缩时泌尿生殖道裂孔的形态。通过智能超声测量了裂孔面积、前后径、横径和耻骨直肠肌厚度等参数，并计算了不同手法下各参数的D值。同时，测量两组骨盆肌肉的力量，并比较超声直径和肌肉力量。结果在第一次自然分娩和第二次自然分娩期间，静息动作中双侧耻骨直肠肌的裂孔面积、前后径、横径和厚度分别为（15.92±2.76）cm2/16.65±2.63）cm2/40.93±5.63）mm/40.27±6.21）mm、（55.54±6.05）mm/57.92±5.27）mm、，这些数据分别为（11.76±2.62）cm2与（12.09±2.78）cm2、（37.57±5.46）mm与（37.18±4.71）mm、（42.21±5.69，3（1.00，5.00）mm vs 1（1.00，5.25）mm，（13.33±6.07）mm vs（14.41±6.54）mm，结论与初产妇和足月顺产产妇相比，无异常妊娠史和并发症的二、足月顺产妇女，智能超声对盆底肌收缩的影响不显著。为二次分娩方式的选择和产后康复提供理论依据。关键词：超声检查；盆底；盆底肌；收缩；产后女性
