超声测量育龄期未生育女性腹直肌间隙

Ultrasonic measurement of inter-recti distance in unborn fertile women

目的观察超声测量育龄期未生育女性腹直肌间隙(IRD)的价值。方法随机选取330名接受体检的育龄期健康女性,分别于其平卧及屈膝卧位下,采用高频超声探头于脐上3 cm、紧贴脐上缘、紧贴脐下缘及脐下3 cm处测量IRD,即左、右侧腹直肌内缘的距离;于脐水平测量左右侧腹直肌厚度。结果平卧和屈膝状态下,育龄期未生育女性脐上3 cm处IRD宽度分别为(10.46±3.91)和(10.82±3.87)mm,紧贴脐上缘处IRD宽度分别为(11.84±4.54)和(12.36±4.52)mm,紧贴脐下缘处分别为(9.53±3.72)和(9.76±3.95)mm,脐下3 cm处宽度分别为(5.87±2.46)和(6.13±2.65)mm;其脐上3 cm处左、右侧腹直肌厚度分别为(10.05±1.41)和(10.26±1.40)mm、(9.73±1.24)和(9.85±1.28)mm。屈膝卧位下,各部位IRD宽度(除脐下缘处)大于平卧下(P均<0.05),且IRD宽度在紧贴脐上缘处最大、脐下3 cm处最小((P均<0.001);左、右侧腹直肌厚度在屈膝卧位下大于平卧下(P均<0.05)。结论超声测量IRD安全、便捷;育龄期未生育女性正常IRD在不同状态及不同位置均有所不同。

Objective To observe the value of ultrasonic measurement of inter-recti distance(IRD)in unborn fertile women.Methods A total of 330 healthy unborn fertile women who underwent physical examination were randomly selected.IRD and the thickness of rectus abdominis muscle were measured with high frequency ultrasound under supine position and dorsal recumbent position,respectively.IRD,i.e.the distance between the inner edges of the left and right rectus abdominis,were measured at 3 cm above the umbilicus,close to the upper edge of the umbilicus,close to the lower edge of the umbilicus and 3 cm below the umbilicus,respectively,while the thickness of the left and right rectus abdominis were measured at the umbilical level.Results Under supine position and dorsal recumbent position,the width of IRD at 3 cm above the umbilicus was(10.46±3.91)mm and(10.82±3.87)mm,at the location close to the upper edge of umbilicus was(11.84±4.54)mm and(12.36±4.52)mm,close to the lower edge of umbilicus was(9.53±3.72)mm and(9.76±3.95)mm,at 3 cm below umbilicus was(5.87±2.46)and(6.13±2.65)mm,respectively.Meanwhile,the thickness of left and right rectus abdominis under supine position and dorsal recumbent position was(10.05±1.41)mm and(10.26±1.40)mm,(9.73±1.24)mm and(9.85±1.28)mm,respectively.Under dorsal recumbent position,all parts IRD except for the lower edge of umbilicus were wider than those under supine position(all P<0.05).The widest IRD was found close to the upper edge of the umbilicus,while the narrowest IRD was observed at 3 cm below the umbilicus.Under dorsal recumbent position,the left and right rectus abdominis were thicker than under supine position(all P<0.05).Conclusion IRD could be safely and conveniently measured with ultrasound,which of healthy unborn fertile women might be various among different parts and under different positions.
