【摘要】 目的:建立妊娠晚期胎儿结肠内径正常参考值范围。方法:193例健康妊娠妇女,正常单胎妊娠36～40+3周,应用实时彩色超声诊断仪测量各妊娠周胎儿结肠最大内径。结果:36～36+6周、37～37+6周、38～38+6周、39～39+6周和≥40周胎儿结肠内径正常平均值及95%可信区间上限分别为(11.03±2.19)mm、(13.27±1.84)mm、(14.94±2.40)mm、(16.22±2.01)mm和(17.26±3.68)mm以及15.8 mm、16.24 mm、18.57 mm、19.24 mm和22.92 mm。结论:提供妊娠晚期各妊娠周胎儿结肠内径正常值范围,可作为评估结肠宫内发育情况以及探查胎儿肠管发育异常的参考值。更多还原

【Abstract】 Objective:To construct a normal value range for the internal diameter of fetal colon in late pregnant term.Methods:193 cases of healthy pregnant women with normal singleton pregnacies at 36～40 weeks+3 days of gestation.Measured the maximum internal diameter of fetal colon.Results:The normal mean and the 95% prediction limits were defined.Conclusions:The present data provide a normal value range of fetal colon in different gestational age of late pregnant term,may evaluate the development of fetal colon and serve as a reference values in the detection of anomalies of the fetal bowel by ultrasound.更多还原
