Diabetes Mellitus represents an important medical problem during pregnancy, causing perinatal morbidity & mortality. The role of Doppler ultrasound in antenatal surveillance of diabetic pregnancies not complicated by fetal growth restriction or hypertension is controversial & whether the Doppler ultrasound can predict neonatal outcome remains unsettled. Doppler studies of the fetal umbilical & middle cerebral arteries can detect the vascular changes in the fetal circulation that may occur in association with diabetic pregnancies, and whether these findings can be correlated to the fetal outcome or the blood glucose level remains controversial Another form of fetal surveillance is the use of computerized cardiotocography (CTG).Absent episodes of high variations are thought to be sensitive markers of fetal death.
