Abstract:
Objective To explore the changes and clinical significance of gestational diabetes mellitus in late pregnancy with fetal ductus venosus blood flow waveform parameters.Methods 23 cases of 24-40 gestational weeks gestational diabetes and 60 cases of normal fetus were selected,color Doppler ultrasonography in the venous catheter into the subarachnoid catheter blood flow waveform was applied to record,including the determination of blood flow parameters:ventricular peak systolic velocity ( DVS) ,left ventricular diastolic peak flow velocity ( DVD) ,atrial systol-ic peak velocity (DVA),and DVRI=(DVS-DVA)/DVS.Results DVS(42.72 ±3.63)cm/s,DVA (12.34 ± 3.11)cm/s and DVRI(0.49 ±0.08) of fetal ductus venosus gestational diabetes group and normal pregnancy group had significant difference (t=3.232,9.664,2.470,all P<0.05),especially the difference between the two groups of DVRI had statistically significant.Conclusion Color Doppler flow spectrum curve of ultrasonic detection of fetal duc-tus venosus have clinical significance in gestational diabetes mellitus.
