To examine the delivery mode and neonatal outcome after a trial of external cephalic version (ECV) procedures.
This is an interim analysis of an ongoing larger prospective off-centre randomised trial, which compares a clinical hypnosis intervention against neuro-linguistic programming (NLP) of women with a singleton breech foetus at or after 37(0/7) (259 days) weeks of gestation and normal amniotic fluid index. Main outcome measures were delivery mode and neonatal outcome.
On the same day after the ECV procedure two patients (2 %), who had unsuccessful ECVs, had Caesarean sections (one due to vaginal bleeding and one due to pathological CTG). After the ECV procedure 40.4 % of women had cephalic presentation (n = 38) and 58.5 % (n = 55) remained breech presentation. One patient remained transverse presentation (n = 1; 1.1 %). Vaginal delivery was observed by 73.7 % of cephalic presentation (n = 28), whereas 26.3 % (n = 10) had in-labour Caesarean sections. Of those, who selected a trial of vaginal breech delivery, 42.4 % (n = 14) delivered vaginally and 57.6 % (n = 19) delivered via Caesarean section. There is a statistically significant difference between the rate of vaginal birth between cephalic presentation and trial of vaginal breech delivery (p = 0.009), however, no difference in neonatal outcome was observed.
ECV is a safe procedure and can reduce not only the rate of elective Caesarean sections due to breech presentation but also the rate of in-labour Caesarean sections even if a trial of vaginal breech delivery is attempted.
探讨外倒转术(ECV)后分娩方式和新生儿结局。
这是一项正在进行的大型前瞻性非中心随机试验的中期分析,该试验比较了在 37(0/7)(259 天)周妊娠及正常羊水指数时,单臀先露胎儿的临床催眠干预与神经语言程序学(NLP)对女性的影响。主要结局指标为分娩方式和新生儿结局。
在 ECV 术后同一天,2 名(2%)ECV 不成功的患者行剖宫产术(1 例因阴道出血,1 例因病理 CTG)。ECV 术后 40.4%的女性呈头位(n=38),58.5%(n=55)仍为臀位。1 名患者仍为横位(n=1;1.1%)。73.7%(n=28)的头位患者行阴道分娩,26.3%(n=10)行产时剖宫产术。在选择阴道臀位分娩试验的患者中,42.4%(n=14)经阴道分娩,57.6%(n=19)行剖宫产术。头位与阴道臀位分娩试验的阴道分娩率存在统计学差异(p=0.009),但新生儿结局无差异。
ECV 是一种安全的方法,不仅可以降低因臀位选择剖宫产的比率,还可以降低即使尝试阴道臀位分娩试验也会进行的产时剖宫产率。
