Study on the Intervention of Early Preterm Labor

Objective:The purpose of this study was to evaluate the measure of emergency cervical cerclage combined with tocolytic in preterm labour and seek for the optimal opportunity and approach for intervention of early preterm labor.Methods:Seventy three cases with preterm labor were enrolled in this study before 34 gestational weeks.39 cases with cervical dilatation 5 cm who received emergency cervical cerclage combined with tocolytic and 34 cases tocolytic alone were analized.The clinical outcomes were compared between two groups using univariate analysis and multivariate logistic regression analysis.Results:The average prolongation of gestation and the rate of deliver after 34 weeks gestation were significantly higher in group received emergency cervical cerclage combined with tocolytic than cases in single tocolytic therapy group(P0.01).Conclusions:This study showed that tocolytic prolonged pregnancy in pregnant women with symptoms of preterm labor.This delay was sufficient to allow treatment with antenatal steroids.Intervention of emergency cervical cerclage combined with tocolytic increased the delivery rate after 34 gestational weeks in preterm labor with advanced cervical dilatation 5 cm.
