目的：分析7~13周正常胎儿羊水体积及其头臀径的关系。方法选取P7~13周头臀径为10~65皂皂的正常胎儿281例，利用二维超声测量其羊水体积和头臀径(CRL)，并对头臀径与羊水体积进行相关性研究。结果胎儿羊水体积与头臀径呈正相关(则越0.913，P<0.001)，回归方程为：羊水体积(糟皂3)越-12.41+1.25×头臀径(皂皂)。281例胎儿头臀径平均测值为(35.42±15.74)皂皂，中位数为32.00皂皂；羊水体积的平均体积为(31.692±21.458)糟皂3，中位数为29.029糟皂3；中位数预测值从头臀径为10皂皂时的0.188糟皂3(范围0.140~0.278糟皂3)增加至头臀径为65皂皂时的65.236糟皂3(范围58.660~74.723糟皂3)。结论P7~13周正常胎儿羊水体积的变化规律及其正常测量数据可为临床早期评价胎儿的预后提供重要的依据。

Objective To analyze the relationship of amniotic fluid volume and crown rump length (CRL) in normal fetus at 7 to 13 weeks. Methods 281 cases of normal fetus with 10 to 65 mm CRL at 7 to 13 weeks were selected, their amniotic fluid volume and CRL were measured by two-dimensional ultrasonography, and the relationship of amniotic fluid volume and CRL was analyzed. Results The amniotic fluid volume of fetus was positively correlated with CRL (r=0.913, P<0.001), the regression equation was:amniotic fluid volume (cm3)=-12.41+1.25íCRL (mm). Of 281 fetus, the mean and median value of CRL was (35.42±15.74) mm and 32.00 mm respectively, the mean and median value of amniotic fluid volume was (31.692±21.458) cm3 and 29.029 cm3 respectively;the median predictive value of CRL increased from 10 mm to 65 mm, the median predictive value of amniotic fluid volume increased from 0.188 cm3 (0.140~0.278 cm3) to 65.236 cm3 (58.660~74.723 cm3). Conclusions The variation law and metrical data of amniotic fluid volume in normal fetus at 7 to 13 weeks can provide important basis for early evaluation of fetal prognosis.
