Assessment of Foetoplacental Blood Flow in Normal Pregnancy Vs Gestational Diabetics Using Color Doppler Indices

The present study was undertaken to assess differences in foetoplacental blood flow in normal pregnancy and gestational diabetics using color Doppler indices which can affect fetal outcome. The study was conducted in 60 pregnant females of age group 25–35 years having 28–34 weeks of gestation divided into two groups: Group A of 30 normal pregnant females and Group B of 30 gestational diabetics. Glucose tolerance test was done in all subjects. Assessment of foetoplacental blood flow was done by measuring PI and RI in umbilical and uterine arteries with the help of color Doppler studies ultrasonologically. Impedance to blood flow was found to be significant in uterine artery as compared to umbilical artery. Resistivity index was found to be more sensitive than Pulsatility index in uterine artery blood flow. The study concluded that color Doppler can help in early assessment of increased impedance to blood flow in gestational diabetics which if timely detected by clinician may prevent intrauterine growth retardation and perinatal mortality.
