title: Amniotic fluid glucose in pregnancies complicated by diabetes.
abstract: Amniotic fluid glucose (AF glu) was studied in 92 pregnancies complicated by maternal diabetes. An inverse relation between AF glu and gestational age was found: [AF glu (mg. per diciliter) = 160.9 -- 3.51 (weeks gestation); r = -0.47]. A direct relation between AF glu and severity of maternal diabetes was observed: mean AF glu (mg. per deciliter) = 24.6 +/- S.D. 12.3 in Class A, 41.2 +/- 25.5 in Class AD and 57.5 +/- 36.5 in Classes B-D. A positive correlation of AF glu with osmolality was observed [AF Osm (mOsm. per kilogram) = 250.7 + 0.22 AF glu; r = +0.50], but this relation was remarkable inconsistent in individual patients. Neither individual nor serial AF glu levels were of any prognostic value in predicting fetal condition or perinatal outcome.
