To explore the effects of Salvia Root injection combined with intravenous infusion in treating oligohydramnios during pregnancy.Methods:A total of 137 cases of oligohydramnios patients were randomly divided into two groups; the control group were given intravenous infusion therapy,the observation group adopted Salvia Root injection based on the control group’s treatment.The curative effects of the two groups were compared.Results:The amniotic fluid index,maximum amnionic fluid pool depth were significantly higher than those before treatment in the two groups,the maximum velocity of the umbilical artery systolic/diastolic flow velocity were significantly lower after treatment,and the differences were statistically significant (P<0.05); the results of the observation group were better than control group (P<0.05); the cesarean section,premature delivery,neonatal pneumonia,neonatal asphyxia incidence of the observation group were significantly lower than those of control group,and the differences were statistically significant (P<0.05); no puerperal disease or intrauterine infection were observed in the two groups.Conclusion:Salvia Root injection combined with intravenous infusion therapy can significantly increase amniotic fluid volume and improve the pregnancy outcome with safety and reliability in the treatment of oligohydramnios during pregnancy
