The study estimated the impacts of water sac of different capacities combined with oxytocin (OXT) on pregnant women with high-risk term pregnancies.
Women with high-risk term pregnancies who received OXT were enrolled to perform labor induction using 30 mL (group A), 80 mL (group B), and 150 mL (group C), followed by the comparisons regarding to the success rate of labor induction, cesarean section rate, duration of induced labor to labor, duration of the first stage of labor, postpartum blood loss, the incidence of adverse reactions, and the assessment of cervical ripening using Bishop Score. Besides, neonatal weight, Apgar score, as well as psychological status, and satisfaction of patients were compared among these groups.
As compared with group A, the success rate of induced labor was higher in groups B and C with lower cesarean section rate and shorter duration of induced labor to labor, but the duration of the first stage of labor in group B was the shortest among the three groups. The amount of postpartum hemorrhage decreased stepwise from groups A to B to C. In addition, groups A and B showed a reduced incidence of adverse reactions than group C, but the highest level of cervical ripening and highest patient satisfaction was revealed in group C and group B, respectively. Furthermore, the highest patient satisfaction was found in group B.
The usage of an 80 mL water sac combined with OXT in high-risk term pregnancy has ideal induction effects, which can guarantee maternal cervical maturity and shorten the time of the first stage of labor.
本研究评估不同容量水囊联合缩宫素（OXT）对高危足月妊娠孕妇的影响。
纳入接受OXT的高危足月妊娠妇女，分别使用30 mL（A组）、80 mL（B组）和150 mL（C组）的水囊进行引产，随后比较引产成功率、剖宫产率、引产至分娩的时间、第一产程时间、产后出血量、不良反应发生率以及使用Bishop评分评估宫颈成熟度。此外，还比较了这些组之间的新生儿体重、Apgar评分以及患者的心理状态和满意度。
与A组相比，B组和C组的引产成功率更高，剖宫产率更低，引产至分娩的时间更短，但B组的第一产程时间在三组中最短。产后出血量从A组到B组再到C组逐步减少。此外，A组和B组的不良反应发生率低于C组，但C组的宫颈成熟度最高，B组的患者满意度最高。此外，B组的患者满意度最高。
在高危足月妊娠中使用80 mL水囊联合OXT具有理想的引产效果，可保证产妇宫颈成熟，缩短第一产程时间。
