Sonographic measurement of amniotic fluid volume in the first trimester of pregnancy.
The sonographic estimate of amniotic fluid volume from 7 to 13 weeks of gestation in 95 pregnancies was calculated. Amniotic fluid volume increased from 1.5 ml at 7 weeks to 25 ml at 10 weeks and 100 ml at 13 weeks. The nomograms constructed may be used in the objective evaluation of the fetal condition in the first trimester.
