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)cm 2 vs (16.65±2.63)cm 2, (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)cm 2 vs (12.09±2.78)cm 2, (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)cm 2 vs (4.43±2.70)cm 2, 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.
