To evaluate the changes of rectus abdominis thickness and inter-rectus distance before and after delivery with high-frequency ultrasound.
A total of 148 pregnant women at 12 weeks of gestation who underwent prenatal examination in our hospital from January 2019 to March 2020 were selected, and 140 of them cooperated with rectus abdominis examination. According to the results of rectus abdominis examination 42 days after delivery, 97 patients were divided into the DRA group with rectus abdominis isolated and 43 patients were divided into the normal group with rectus abdominis not isolated. At 12 weeks, 24 weeks, and 37 weeks of pregnancy, 3 days and 42 days after delivery, the thickness and spacing of the left and right rectus abdominis muscle were measured by high-frequency ultrasound along the white linea at three positions: 5 cm above the navel, 3 cm below the umbilical edge, and 3 cm below the navel.
The thickness of rectus abdominis at 5 cm above the navel, 3 cm below the navel, and at the navel margin of the abdominal white line in the pregnant women of the two groups was gradually decreased with the increase of the pregnancy cycle and gradually recovered after delivery. At 42 days after delivery, the thickness of rectus abdominis in the DRA group was significantly lower than that in the normal group, which was 5 cm above the umbilicus, 3 cm below the umbilicus, and the umbilical margin of the abdominal white line ( < 0.05). The space between rectus abdominis 5 cm above the navel, 3 cm below the navel, and the navel margin of the abdominal white line in the pregnant women of the two groups was gradually increased with the increase of the pregnancy cycle and gradually recovered after delivery. At 37 weeks of pregnancy, 3 days after delivery, and 42 days after delivery, the space of rectus abdominis along the umbilicus 5 cm above, 3 cm below the umbilicus, and the umbilicus border of the abdominal white line in the DRA group was significantly larger than that of the normal group ( < 0.05).
Ultrasound can accurately measure the inter-rectus distance and rectus thickness, accurately evaluate the degree of DRA, and realize the one-stop evaluation from prenatal diagnosis and prediction to postpartum rehabilitation monitoring, so as to intervene during pregnancy and reduce the risk of postpartum DRA.
采用高频超声评估分娩前后腹直肌厚度及腹直肌间距的变化。
选取2019年1月至2020年3月在我院进行产前检查的148例孕12周孕妇，其中140例配合腹直肌检查。根据产后42天腹直肌检查结果，将97例腹直肌分离患者分为腹直肌分离（DRA）组，43例腹直肌未分离患者分为正常组。在妊娠12周、24周、37周，产后3天及42天，沿腹白线在脐上5 cm、脐下缘3 cm、脐下3 cm三个位置，采用高频超声测量左右腹直肌的厚度及间距。
两组孕妇在脐上5 cm、脐下3 cm及腹白线脐缘处的腹直肌厚度均随孕周增加而逐渐减小，产后逐渐恢复。产后42天，DRA组在脐上5 cm、脐下3 cm及腹白线脐缘处的腹直肌厚度明显低于正常组（P<0.05）。两组孕妇在脐上5 cm、脐下3 cm及腹白线脐缘处的腹直肌间距均随孕周增加而逐渐增大，产后逐渐恢复。在妊娠37周、产后3天及42天，DRA组在脐上5 cm、脐下3 cm及腹白线脐缘处的腹直肌间距明显大于正常组（P<0.05）。
超声可准确测量腹直肌间距及厚度，准确评估DRA程度，实现从产前诊断预测到产后康复监测的一站式评估，以便在孕期进行干预，降低产后DRA发生风险。
