高频超声在产后腹直肌分离评估中的应用价值

Application value of high-frequency ultrasound in the assessment of postpartum rectus abdominis separation

目的探讨高频超声在产后腹直肌分离评估中的应用价值。方法选取2018年5月至2020年5月在深圳市龙华区妇幼保健院产科进行分娩并实施产后6周检查的产妇100例,按照分娩方式分为剖宫产组(54例)与自然分娩组(46例),均施以高频超声检测。比较两组腹直肌分离检出率、不同状态下腹直肌间距。结果100例产妇腹直肌分离检出率为78.00%,以脐上缘分离居多。自然分娩组腹直肌分离率为67.39%较剖宫产组的87.04%低(P<0.05)。自然分娩组静息条件下脐下缘、脐上缘、脐上3 cm、脐上4.5 cm及屈曲条件下脐上缘、脐下缘腹直肌间距较剖宫产组低(P<0.05)。结论高频超声在超声腹直肌分离诊断中具有良好指导作用,并能有效显示产后腹直肌分离程度及恢复情况,值得临床广泛实践及推广。

Objective To explore the application value of high-frequency ultrasound in the assessment of postpartum rectus abdominis separation.Methods A total of 100 women who gave birth in Shenzhen Longhua District Maternity and Child Healthcare Hospital from May 2018 to May 2020 and underwent a 6-week postpartum checkup were selected.According to the delivery method,they were divided into the cesarean delivery group(54 cases)and the natural delivery group(46 cases),with both group subject to high-frequency ultrasonic testing.The detection rate of rectus abdominis separation and the distance between the rectus abdominis muscles under different conditions were compared between the two groups.Results The detection rate of rectus abdominis separation in 100 postpartum women was 78.00%,most of which showed separation at the upper edge of the navel.The incidence of rectus abdominis separation in the natural delivery group(67.39%)was lower than that in the cesarean delivery group(87.04%)(P<0.05).In the natural delivery group,the distances between the rectus abdominis muscles under the resting condition(at the lower edge of the navel,the upper edge of the navel,3 cm above the navel,4.5 cm above the navel)as well as under the flexion condition(at the lower edge of the navel and the upper edge of the navel)were smaller than those in the cesarean delivery group(P<0.05).Conclusion High-frequency ultrasound plays a good guiding role in the ultrasonic diagnosis of rectus abdominis separation,and can effectively show the degree of postpartum rectus abdominis separation and recovery.It is worthy of extensive clinical practice and promotion.
