Objective,2,To explore the curative effect of Chen’s Zhimu San combined with intravenous infusion in the treatment of suspicious oligohydramnios.,Methods,2,A total of 141 pregnant women with suspicious oligohydramnios were included and randomly divided into the western medicine group (66 cases) and the integrated traditional Chinese and western medicine group (75 cases). The patients in the western medicine group were treated with intravenous infusion, and the patients in the integrated traditional Chinese and western medicine group were orally treated with Chen’s Zhimu San based on intravenous infusion. The treatment course was 7 days. Before and after treatment, the whole blood viscosity and plasm viscosity were detected, the amniotic fluid index (AFI) and ratio of end systolic peak (S) to end diastolic peak (D) of fetal umbilical artery blood flow (S/D ratio) were measured and calculated by B-mode ultrasonography, and the scores of Chinese medical syndrome in both groups were evaluated and compared.,Results,2,①After treatment, the AFI was increased and the fetal umbilical artery S/D ratio was decreased in the two groups (,P,<,0.05), and the AFI in the integrated traditional Chinese and western medicine group was higher than that in the western medicine group (,P,<,0.05), the fetal umbilical artery S/D ratio was lower than that in the western medicine group (,P,<,0.05). ②After treatment, the scores of Chinese medical syndrome in the integrated traditional Chinese and western medicine group were significantly decreased compared with those before treatment (,P,<,0.05), and the scores of the integrated traditional Chinese and western medicine group were lower than those of the western medicine group (,P,<,0.05). ③After treatment, the whole blood viscosity (low shear, medium shear, high shear) and plasm viscosity in the integrated traditional Chinese and western medicine group were decreased compared with those before treatment (,P,<,0.05), the whole blood viscosity (low shear) and plasm viscosity in the western medicine group were also decreased compared with those before treatment (,P,<,0.05), and the whole blood viscosity (low shear, medium shear, high shear) in the integrated traditional Chinese and western medicine group was lower than that in the western medicine group (,P,<,0.05).,Conclusion,2,Compared with intravenous infusion therapy, Chen’s Zhimu San combined with intravenous infusion therapy can better decrease the blood viscosity in the treatment of suspicious oligohydramnios, increase the amniotic fluid volume, and improve the fetal umbilical artery blood flow, thus regulate the local microcirculation of placenta.
