The aim of this study is to examine the effectiveness and adverse effects of local glyceryl trinitrate (GTN) application during labor compared with a placebo group.
The study consisted of 70 pregnant women with overdue pregnancies who presented to the hospital for labor induction between January 2009 and January 2011 in the Obstetrics Clinic of Istanbul Süleymaniye Gynecology and Obstetrics Education and Training Hospital. Vaginal suppositories-containing GTN (36/70) or placebo (34/70) was administered to the participants in a randomized fashion. The placebo and GTN involving vaginal ovules used in the study were prepared in the Pharmacy Department of Istanbul University Faculty of Pharmacy. Maternal effects during labor, rates of normal vaginal and C/S deliveries, the interval between the initial medication and delivery, and amount of total oxytocin used were compared between the GTN and placebo groups.
There were no significant differences between the GTN and placebo groups regarding bishop scores, the interval between medication and delivery, delivery types, indications for cesarean section, and complications including hyperstimulation, tachysystole, uterine rupture, placental abruption, and uterine atony ( > 0.05).
Our results revealed that there were no differences between GTN and placebo regarding their effect on cervical ripening in overdue pregnant women.
本研究旨在比较局部甘油三硝酸酯(GTN)在分娩时的应用与安慰剂组的效果和不良反应。
本研究纳入了 2009 年 1 月至 2011 年 1 月期间在伊斯坦布尔 Süleymaniye 妇产科教育和培训医院妇产科诊所因过期妊娠而入院引产的 70 名孕妇。采用随机方法向参与者阴道内给予含有 GTN(36/70)或安慰剂(34/70)的阴道栓剂。研究中使用的 GTN 涉及的安慰剂和阴道栓剂均由伊斯坦布尔大学药学院药剂科制备。比较 GTN 组和安慰剂组的产妇在分娩过程中的效果、阴道分娩和剖宫产的比例、初始用药与分娩的间隔时间以及催产素的总用量。
GTN 组和安慰剂组在 Bischof 评分、用药与分娩的间隔时间、分娩类型、剖宫产指征以及包括过度刺激、心动过速、子宫破裂、胎盘早剥和子宫乏力在内的并发症方面无显著差异(>0.05)。
我们的结果表明,在过期妊娠孕妇的宫颈成熟方面,GTN 和安慰剂的效果没有差异。
