ABSTRACT

Objective To explore the clinical effect of disposable cervical dilator balloon and dinoprostone suppository on promoting cervical ripening in full-term pregnancy.Methods 92 cases of primipara with labor indications were selected as the research subjects.According to the random number table method,the patients were randomly divided into two groups,46 cases in each group.The observation group of cervical ripening used disposable cervical dilator balloon,the control group used dinoprostone suppository .The cervical Bishop score and cervical ripening effect ,delivery conditions,and the incidence of adverse reactions were compared between the two groups .The full-term pregnancy cervical ripening in disposable balloon dilator ,the application effect of dinoprostone suppository was evaluated .Results The cervical Bishop score after induction of the observation group was (8.92 ±0.17) points,which was higher than (6.11 ±0.38) points of the control group,the difference was statistically significant (t=45.781,P<0.05).The ineffective rate of cervical ripening in the observation group was 4.35％,which was lower than 26.09％in the control group(χ2 =16.133,P<0.05).The induced to regular uterine contraction time ,the total labor range of the observation group were (6.31 ±1.52)h,(6.35 ±1.59)h,respectively,which were shorter than those of the control group[(11.68 ± 2.24)h,(7.56 ±2.68)h],the differences were statistically significant (t=13.454,2.634,all P<0.05).The vaginal delivery rate of the observation group was 82.61％,which was higher than 63.04％of the control group(χ2 =4.056, P<0.05).The cesarean section rate of the observation group was 17.39％,which was lower than 36.96％ of the control group(χ2 =7.407,P<0.05).The neonatal birth weight,neonatal asphyxia,neonatal Apgar score between the two groups had no statistically significant differences(all P>0.05).The incidence rate of adverse reactions in the observation group was 8.70％,which was lower than 28.26％in the control group(χ2 =9.757,P<0.05).Conclusion Dispos-able balloon cervical dilator used in term pregnancy cervical ripening has significant effect , can improve cervical ripening rate,shorten delivery time and labor ,with less adverse reaction ,high safety,it is worthy of reference .
