ABSTRACT
Objective To explore the clinical effects of single-cavity and COOK cervical ripening balloon in promoting full-term pregnancy cervical mature and inducing labour. Methods 126 puerpera who were expect-ant in the obstetrics department of our hospital were selected from January 2016 to June 2017,and all of the puer-pera were induced labor by cervical ripening balloon.In 61 of them,single-cavity balloon was used,and 65 cases were induced labor by COOK balloon. Determining the cervical ripening situation,the time needed for inducing efficient uterine contraction,the first stage of labor time,the total labor time,vaginal delivery rate,natural labor situation,postpartum hemorrhage,amniotic fluid turbidity,puerperal infection and newborn asphyxia of the two groups.Results the time needed for inducing efficient uterine contraction of the two groups were(16.39±2.68)h, (14.54 ± 3.30)h,and the two groups were statistically different(P<0.05).There were no statistically significant differences in other items of two groups(P>0.05).Conclusion single-cavity balloon and COOK balloon are sim-ilar in promoting full-term pregnancy cervical ripening.The difference is that the time needed for inducing efficient uterine contraction of the single-cavity balloon is longer than COOK balloon,but have no adverse effect to the puer-pera and the newborn.Both types of balloons are recommended to be used in promoting full-term pregnancy cervical ripening and inducing labor.
