摘　　要：目的探讨高频超声评估自然分娩后女性腹部核心肌各肌层厚度、肌肉收缩率,分析其产后形态及收缩能力的价值。方法选取自然分娩后2 d、自然分娩后6周及未育未孕的女性各31名作为研究对象(即A、B、C组)。采用高频超声扫查3组女性的腹部核心肌,测量并比较3组平静呼气末、腹式吸气末与最大呼气末右侧腹横肌(TrA)、腹内斜肌(IO)、腹外斜肌(EO)的厚度及收缩率。结果 A组TrA、IO及EO的厚度明显高于B、C组(P<0.01)。A组TrA的收缩率最低(P<0.01),B、C组TrA厚度及收缩率、IO和EO厚度的差异无统计学意义(P>0.05)。3组IO及EO收缩率的差异未达统计学意义(P>0.05)。3组内核心肌厚度依次为IO>EO>TrA,收缩率依次为TrA>IO>EO。结论 TrA厚度及收缩率在自然分娩后女性腹部核心肌中变化最大,可能是产后机体重塑的重要结构;高频超声能够准确评估女性腹部核心肌情况,具有重要的临床价值。Objective To explore the value of high-frequency ultrasonography in the evaluation of the thickness and muscle contraction rate of abdominal muscles of females after natural delivery and the analysis on its morphology and contractility.Methods Thirty-one females 2 days and 6 weeks after natural delivery were respectively selected as Group A and Group B,and thirty-one unmarried young women were selected as control group(Group C).High-frequency ultrasonography was used to scan the abdominal core muscles of the three groups,and the thickness and contraction rate of right transverse abdominis muscle(TrA),internal oblique muscle(IO)and external oblique muscle(EO)of the three groups at the end of calm expiration,the end of abdominal respiration and the end of maximum expiration were measured and compared.Results The thickness of TrA,IO and EO in Group A was significantly thicker than that in Group B and C(P<0.01).The contraction rate of TrA in Group A was the lowest(P<0.01).There was no significant difference in the thickness and contraction rate of TrA between Group B and C(P>0.05).There was no statistical difference in the thickness of IO and EO between Group B and Group C(P>0.05).There was no statistical difference in the contraction rate of IO and EO between the three groups(P>0.05).The muscle thickness in each of three groups was IO>EO>TrA while the muscle contraction rate in each of the three groups was TrA>IO>EO.Conclusion The thickness and contractility of TrA had the most significant change in the postpartum women,indicating that it may be an important factor in the reshaping of postpartum women.High-frequency ultrasonography can accurately evaluate the abdominal core muscles of postpartum women and has important clinical value.
