Abstract:Objective To explore the clinical effects of two kinds of cervical dilation balloon in promoting full-term pregnancy cervical mature.Methods 104 single fetal head primipara who were expectant in our hospital from October 2015 to February 2016 were selected.All of the primipara had induced labor indications,and cervical Bishop score was less than 6 scores.Patients were randomly divided into two groups.54 patients were used COOK double cavity cervical expanding balloon (COOK balloon group),and 50 patients were used single cavity cervical expanding balloon(single cavity balloon group).After using balloon,the cervical ripening,placing time,natural labor situation after placement,vaginal delivery rate,postpartum hemorrhage,newborn asphyxia,blood routine test in postpartum 24 h and maternal satisfaction in two groups were compared.Results Before induced labor,the cervical Bishop score between two groups had no statistical difference(P>0.05).The average placing time in COOK balloon group was(11.00±1.66)h,shorter than(13.10± 3.56)h in single cavity balloon group,and the difference was statistical significance (P<0.01).The natural labor rate in COOK balloon group and single cavity balloon group was respectively 15.7%and 24.0%,promoting cervical mature effective rate was respectively 88.9%and 86.0%,vaginal delivery rate was respectively 76.9%and 72.0%,and all differences had no statistical significance(P>0.05).Birth weight of newborn in COOK balloon group and single cavity balloon group was respectively(3220.00±356.90)g and (3102.00±403.85)g,newborn asphyxia rate was respectively 3.7%and 2.0%,postpartum hemorrhage rate was respectively 5.6%and 8.0%,white blood cell count in postpartum 24 h was respectively(12.2±2.5)×109/L and(12.5±2.7)×109/L,maternal satisfaction was respectively 85.1%and 78.0%,and all differences had no statistical significance(P>0.05).Conclusion The effects of COOK double cavity cervical expanding balloon with single cavity cervical expanding balloon in promoting cervical mature are similar,the placing time of single cavity cervical expanding balloon is longer than that of COOK double cavity cervical expanding balloon,but has no adverse impact on newborns and primipara.So two kinds of methods can be widely used in clinic to promote cervical mature.
