Fifty-three diabetic pregnant treated in Dpt of Obstetrics and Perinatology in Lublin were investigated. The paper presents correlations between metabolic parameters in diabetic patients and Doppler welocimetry in umbilical and middle cerebral arteries and also analyses way of delivery and outcomes. Correlations between fetal Doppler parameters and metabolic status of mothers have been found. We estimate that Doppler velocimetry hasn't prognostic value in predicting of fetal distress.
