二维超声检测孕7~13周胎儿羊水体积的研究
Research on Two-dimensional Ultrasonography in Detection of Amniotic Fluid Volume of Fetus at 7 to 13 Weeks
摘要
Abstract
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.关键词
