目的:观察比较双球囊导管与地诺前列酮栓促宫颈成熟的临床效果。方法:选择足月且有引产指征初产妇214例,随机分为双球囊导管组113例和地诺前列酮栓组101例。地诺前列酮栓组将地诺前列酮栓剂置于后穹窿促宫颈成熟;双球囊导管组将双球囊导管置入宫颈管内促宫颈成熟,内外球囊各注入生理盐水80ml。均在取出后1h加用缩宫素引产。观察比较两组引产后宫颈评分改善、产程时限、阴道分娩率及新生儿出生体重等指标。结果:两组引产后宫颈Bishop评分及宫颈评分提高≥3分者构成比比较,均差异不显著(P>0.05)。双球囊导管组诱发临产时间、产程时限,均显著或非常显著短于地诺前列酮栓组(P<0.05,P<0.01)。两组阴道分娩率及新生儿出生体重比较,均差异不显著(P>0.05)。结论:双球囊导管与地诺前列酮栓均能有效提高宫颈评分,促进宫颈成熟,提高引产成功率,但双球囊导管在缩短引产时间及产程时限,减轻分娩痛苦,提高患者依从性方面优于地诺前列酮栓。
OBJECTIVE: To observe and compare the clinical effects of double balloon catheter and dinoprostone on cervical ripening. Methods: A total of 214 cases of primipara caused by induced labor were enrolled in this study. They were randomly divided into double balloon catheter group (113 cases) and dinoprostone suppository group (101 cases). The dinoprostone suppository group was placed in the posterior fornix to promote cervical ripening. The double-balloon catheter group was placed into the cervical canal to promote cervical ripening. The internal and external balloons were each infused with 80 ml normal saline. After removal of 1h plus oxytocin abortion. Observed and compared the two groups of post-labor cervical score improvement, labor duration, vaginal delivery rate and newborn birth weight and other indicators. Results: There was no significant difference between the two groups (P <0.05) in Bishop cervical score and cervical score ≥3. Double balloon catheter induced labor time, labor duration, were significantly or very significantly shorter than dinoprostone suppository group (P <0.05, P <0.01). There was no significant difference in vaginal delivery rate and newborn birth weight between the two groups (P> 0.05). Conclusion: Both double balloon catheter and dinoprostone suppository can effectively improve cervical score, promote cervical ripening and improve the success rate of induced labor. However, double balloon catheter can shorten the time of labor and labor, reduce labor pain and improve patient compliance Better than dinoprost suppository.
