目的:通过对延期妊娠孕妇静脉滴注0.2%缩宫素与0.5%缩宫素两种浓度,比较其促宫颈成熟及引产效果和超声下宫颈形态的变化。方法:对227例孕41～41+6周延期妊娠孕妇随机分成两组,各静脉滴注一种浓度缩宫素,比较两种浓度缩宫素促宫颈成熟及引产效果。结果:宫颈Bishop评分<7分者,两种浓度缩宫素提高宫颈评分差异无统计学意义(P>0.05),宫颈Bishop评分≥7分者,两种浓度缩宫素分娩率差异有统计学意义(P<0.05),并与超声监测下宫颈形态变化呈一致性。结论:低浓度缩宫素能产生有效宫缩,促宫颈成熟引产安全有效。宫颈Bishop评分<7分者,0.2%缩宫素发生胎儿窘迫率低,可作为促宫颈成熟引产首选;宫颈Bishop评分≥7分者,0.5%缩宫素促宫颈成熟引产催产效果好。
OBJECTIVE: To compare the effects of cervical ripening, induction of labor and cervical morphology under ultrasound by intravenous infusion of 0.2% oxytocin and 0.5% oxytocin in pregnant women with postprandial pregnancy. Methods: A total of 227 pregnant women with pregnant 41-41 + 6-week postprandial pregnancy were randomly divided into two groups, each of which was given a concentration of oxytocin. The two kinds of oxytocin were compared to promote cervical ripening and induction of labor. Results: Cervical Bishop score <7 points, two concentrations of oxytocin increased cervical score was no significant difference (P> 0.05), cervical Bishop score ≥ 7 points, two concentrations of oxytocin delivery rates were statistically significant Significance (P <0.05), and with the ultrasound monitoring of cervical morphology consistent. Conclusion: Low concentration of oxytocin can produce effective contractions, and promote cervical ripening is safe and effective. Cervical Bishop score <7 points, 0.2% oxytocin fetus with low fetal distress rate can be used as the first choice to promote cervical ripening; cervical Bishop score ≥ 7 points, 0.5% oxytocin to promote cervical ripening induction of labor is good.
