  • Title: Increased fetal activity with low maternal blood glucose levels in pregnancies complicated by diabetes.
    Author: Holden KP, Jovanovic L, Druzin ML, Peterson CM.
    Journal: Am J Perinatol; 1984 Jan; 1(2):161-4. PubMed ID: 6518063.
    Abstract:
    Ten diabetic pregnant women were studied during the thirty-sixth to fortieth weeks of gestation to determine whether maternal blood glucose levels influence fetal activity. Maternal blood glucose level was monitored and controlled utilizing an artificial pancreas (Biostator) while fetal activity and heart rate were quantitated by continuous ultrasonic and electrocardiac fetal monitoring. Fetal activity was confirmed independently by a maternal controlled event marker. There was no difference in fetal movement with heart rate accelerations between periods of maternal normoglycemia defined as blood glucose levels between 60 and 140 mg/dl (3.3-7.8 mMol/L) and periods of maternal hyperglycemia (blood glucose level greater than 140 mg/dl or 7.8 mMol/L). Maternal blood glucose levels of less than 60 mg/dl (3.3 mMol/L) were accompanied by a significant (p less than 0.001) increase in fetal activity (19.9 +/- 3.9 SEM episodes of fetal movement per 20-minute observation period versus 8.0 +/- 5 episodes during periods of hyperglycemia). These observations indicate that hyperglycemia does not stimulate fetal activity and that the obstetric practice of beverages with high glucose content administered during antepartum testing (in an attempt to increase fetal movement) should be reevaluated in diabetic women.
