目的：通过高频超声检测孕产妇腹直肌间隙距离与传统指测法的比较，探究高频超声辅助腹直肌分离临床诊断的优势。方法：选取在无锡市锡山人民医院产检并符合纳入排除标准的孕产妇195例，分为两组：对照组100例，随机抽取，分阶段产检时间分别为妊娠28、32、35、37周以及产后1、2、3、4、6周，手法检测腹直肌分离程度，以手指触诊间距进行尺度测量；实验组95例，为自愿参加超声检测腹直肌分离程度的孕产妇，分别在相同孕周及产后相同时间点通过高频超声探视下测量腹直肌间隙距离。两组同时进行双盲交替测试，汇总比较两组在测量值、漏诊率等方面的差异。结果：两组孕产妇腹直肌分离数据妊娠28、32周比较差异无统计学意义（P>0.05），妊娠35、37周及产后1、2、3周比较差异有统计学意义（P<0.05），产后4、6周比较差异无统计学意义（P>0.05）；两组诊断率差异无统计学意义（P>0.05）；对照组漏诊率较高（P<0.05）。结论：高频超声检测有利于早期发现和诊断腹直肌分离，漏诊率低，利于实时动态评估孕产妇腹直肌分离症状，以早期预防和治疗。
