Purpose: to study the fetal well-being assessment in pregnancies complicated by diabetes, and to analyze the neonatal results. Methods: we studied 387 pregnant women with diabetes at the Fetal Surveillance Unit. The last examination (cardiotocography, fetal biophysical profile, amniotic fluid index and dopplervelocimetry) was correlated with the neonatal outcome. Results: the studied population included 46 (12%) type I diabetes, 45 (12%) type II and 296 (76%) gestational diabetes. Type I diabetes with abnormal or suspected cardiotocography was related to abnormal 1st minute Apgar (50 and 75%, p<0.05) and to the need for neonatal intensive care unit (50 and 75%, p<0.05). The abnormal biophysical profile in type II diabetic pregnancy was related to the need for neonatal intensive care (67%, p<0.05), and abnormal umbilical artery Doppler study was related to abnormal 1st minute Apgar (67%, p<0.05). Gestational diabetes with abnormal cardiotocography presented 36% abnormal 1st minute Apgar (p<0.05), 18% abnormal 5th minute Apgar (p<0.01) and 18% neonatal death (p<0.01). Abnormal amniotic fluid index was related to abnormal 5th minute Apgar (p<0.05) and need for neonatal intensive care unit (p<0.05). Gestational diabetes with abnormal umbilical artery Doppler was related (p<0.05) to: abnormal 1st and 5th minute Apgar, respectively, 25 and 8%, Need for neonatal intensive care in 17% and neonatal death in 8%. Conclusions: the fetal well-being examinations correlated with adverse perinatal outcome, showing the need for fetal surveillance in diabetic pregnant women.
