The diagnostic significance of the blood flow information of fetus obtained from Doppler ultrasound in the diagnosis of gestational diabetes mellitus / 中国医学装备

ABSTRACT

Objective:To explore the application of fetal multi-organ hemodynamics in the detection and evaluation of oxygen supply and blood supply for fetus in the third trimester of pregnancy. Methods: 42 pregnant women with gestational diabetes mellitus and 42 healthy pregnant women were divided into observation group and control group, respectively. All of the fetuses of pregnant women received Doppler ultrasound examination, and the pulsatility index(PI), resistance index(RI) and systolic/diastolic(S/D) ratio of umbilical artery (UA)and middle cerebral artery (MCA) of every fetus in the two groups were observed. Besides, the number of fetal distress was recorded and the relationship between fetal distress rate and gestational diabetes mellitus were calculated.Results:The PI, RI and S/D of MCA of fetuses of pregnant women with gestational diabetes mellitus was significantly higher than that of healthy pregnant women (t=7.52,t=6.04, t=8.69,P<0.05). And the PI, RI and S/D of UA of fetuses of pregnant women with gestational diabetes mellitus also was significantly higher than that of health pregnant women (t=11.95,t=9.78,t=8.95, P<0.05). Besides, the fetal distress rate of observation group was significantly higher than that of control group (x2=19.56,P<0.05).Conclusion: The fetal blood flow information which obtained from Doppler ultrasound has very importantly value in the diagnosis of gestational diabetes mellitus, and it verifies the relationship between fetal distress rate and gestational diabetes mellitus. It provides beneficial basis for the prevention and treatment of the gestational diabetes mellitus in the clinical practice.
