SHU Weiqun, et al. A new analysis on the clinical use of amniotic fluid index[J]. Journal of Chongqing Medical University, 2004,(2):234-235. DOI: 10.13406/j.cnki.cyxb.2004.02.036.
Objective:To evaluate the diagnostic value of measurement of amniotic fluid index (AFI) by B-mode sonography in oligohydramnios.Methods:AFI was detected in 120 patients with oligohydramnios and compared with true quantity of amniotic fluid during cesarean section.Results:The accurate diagnostic rate of oligohydramnios was 86.7% by ultrasonography
which decreased with the increase in AFI.The diagnostic rate in pregnancy group of high risk or prolonged pregnancy was higher than that in normal group.Conclusion:B-mode sonography is important in hign risk factors and prolonged pregnancies.
