Comparative Analysis Of COOK Cervical Dilated Balloon And Common Ureteral Water Balloon In Promoting Cervical Maturity

Objective:The purpose of this study was to investigate the efficacy,vaginal delivery rate,complications,etc.of COOK balloon and Foleys catheter in promoting cervical ripening in late pregnancy induction,and to find a more suitable method for cervical ripening of pregnant women in late pregnancy,aiming to increase the incidence of vaginal delivery.Possibility to minimize cesarean section and reduce maternal and infant injury.Methods:The first-term women who were hospitalized for labor in the researcher’s hospital from June 2018 to April 2021 were selected,and contraindications were excluded according to the "Guidelines for cervical ripening and labor induction in the third trimester(2014)",and a total of gestational weeks 37-41+6 were included.A total of 115 pregnant women without pregnancy complications and medical and surgical complications were randomly divided into COOK cervical dilation balloon group(COOK group)with 57 cases and Foleys ureteral water balloon group(Foleys group)with 58 cases.The x 2 test was used to analyze and compare the cervical maturity,successful rate of labor induction,vaginal delivery rate,combined oxytocin use rate,patient experience score table,total labor duration,delivery mode,postpartum complications,neonatal score,The onset interval and other indicators were defined from the time the balloon was placed into the uterine cavity to the occurrence of spontaneous and regular uterine contractions,and the effectiveness and safety of the two balloons in promoting cervical ripening and guiding vaginal delivery during labor induction in late pregnancy were evaluated.Result:(1)Both COOK balloon and Foleys catheter can effectively improve cervical Bishop score and promote cervical ripening,but the total effective rate of COOK group is 98.25%,which is higher than that of Foleys group 93.11%,and there is a statistical difference between the two groups(P<0.05).);(2)The onset interval of COOK group was 10.96h;after the balloon was removed,a total of 12 patients needed to receive low-dose oxytocin intravenous infusion,accounting for 21.05%,and the remaining 45 patients had spontaneous regularity when the balloon was removed contractions.The average time between onset of action in the Foleys group was 22.76 hours;after the balloon was removed,a total of 9 cases required additional low-dose oxytocin intravenous drip,accounting for 15.52%,and only 49 cases had spontaneous and regular uterine contractions when the balloon was removed.The COOK group had significantly lower onset time than the Foleys group(P < 0.05),and the proportion of combined low-dose oxytocin was also statistically different(P < 0.05).Foleys group,there is a statistical difference.(3)There were 43 cases of vaginal delivery in COOK group,accounting for75.44%,and 40 cases in Foley group,accounting for 68.97%,and the difference was statistically significant.The COOK group had an average of 5.71 h in the first stage of labor,an average of 1.55 h in the second stage,and an average of 7.61 h in the total stage of labor.There was no significant difference in labor statistics(P>0.05).(4)There was no neonatal asphyxia between the two groups,and there was no difference in the neonatal score(P>0.05).The COOK group had significantly higher vaginal bleeding volume,duration of pain,and dropout rate than the Foleys group.There was no statistical difference between the two groups.(5)After placement,the balloon fell off in COOK group with 12 cases,accounting for 21.05%;Foley group with 9 cases,accounting for 15.52%.For example,9 patients in the Foleys group underwent secondary implantation.After placement,the average vaginal bleeding volume was 24.18 m L in COOK group and23.07 m L in Foley group,and there was a statistical difference between them(P>0.05).Conclusion:(1)Both COOK balloon and Foleys catheter can effectively promote cervical ripening and increase the rate of vaginal delivery in the induction of labor in late pregnancy.(2)COOK balloon is slightly higher than Foleys catheter in complications such as pain duration and vaginal bleeding volume.(3)COOK balloon can not only promote cervical ripening,but also induce uterine contraction,shorten the time of balloon action,reduce the probability of combining with other treatments,and improve the rate of vaginal delivery,which is better than Foleys catheter.
