ABSTRACT
vBackground: Induction of labour is the intentional initiation of labour before spontaneous onset for the purpose of delivery of fetoplacental unit. Failure of induction is responsible for increased incidence of caesarean delivery. This study performed to assess and compare the clinical effects of sustained release vaginal insert versus intracervical gel in primiparous women with term pregnancy in terms of improvement of Bishop’s score, Induction delivery interval, incidence of hyperstimulation, maternal and neonatal outcomes.Methods: A total 100 consecutive term pregnant women who underwent labor induction for fetal or maternal indications were divided randomly into two groups. Group A - sustained release Vaginal insert and Group B - Intracervical gel. Informed consent was taken from each patient.Results: Statistically significant increase in final Bishop’s score (p=0.008) and hyperstimulation (p=0.04) was seen in Vaginal insert group as compared to Intracervical gel group, while there were no statistically significant differences in maternal outcomes, neonatal outcomes and need for oxytocin augmentation in both groups.Conclusions: In this study we found that insert did not improve the induction delivery interval or rate of successful induction, nor did it have any advantage in terms of neonatal outcome although it did improve the Bishops score – Its advantage was in terms of single application, few prevaginal examinations, longer duration of action and immediate retrieval in case of hyperstimulation. Its main drawback remained the maintenance of cold chain without which its efficacy decreases. Another significant observation was the dropout rate of insert (16%).
ABSTRACT
Background: In modern medicine induction of labour is required in patients for a good feto-maternal outcome. PGE2 is a prostaglandin analogue which has been used as a cervical ripening agent to improve bishops score. Objective of this study was to evaluate the efficacy of intravaginal PGE2 gel as a cervical ripening agent in unfavourable cervix for induction of labor and any complications associated with its use.Methods: This study comprised of 90 women who required labor induction. Singleton pregnancy above 37 weeks, live intrauterine fetus, Cephalic presentation, Bishop score of 1-6, reactive FHR pattern were included. Women who required only single induction were categorized as Group 1. Those requiring more than one dose after reassessment of bishops scoring at 6, 12 and 18 hours belonged to Group 2.Results: Group1 had more of younger population below 30 years consisting more primigravidas with > 80% women having gestational age of > 39 weeks. Most common indication for induction of labour in both groups was post-dated pregnancy. 65 patients received one dose of cerviprime gel forming Group 1. In Group 2, 72% received 2 doses and 28%, 3 doses of gel. Initial bishops score mean was 4.2 in Group 1 and 4.1 in Group 2. Mean change in bishop score was analysed after 6, 12, and 18 hours of instillations of PGE2 gel. Significant p value was obtained in all groups requiring one, two and three doses of gel. In Group 1, 12.3% and in Group 2, 16% had LSCS. Maternal side effects were minimal and neonatal outcome was good.Conclusions: The study showed that intravaginal application of PGE2 is effective, safe and acceptable method as a cervical ripening agent for labor induction in women with poor bishops score. It reduces caesarean delivery rate without increasing maternal and neonatal morbidity.
ABSTRACT
Background: Late-term pregnancy defined as one that has reached between 41 0/7 weeks and 41 6/7 weeks of gestation is associated with an increased maternal morbidity as well as an increased risk of fetal and neonatal mortality and morbidity. Mifepristone, an anti-glucocorticoid and antiprogesterone, though not an oxytocic increases uterine activity and causes cervical effacement and dilatation and improves the Bishop score without over/hyper stimulation of uterus. Increased maternal and fetal mortality from late term pregnancy could be prevented by induction of labour. The objective of this study was to know the efficacy of single dose of oral mifepristone in induction of labour in late term pregnancy and to assess the induction delivery interval in the study population.Methods: This was a prospective interventional study conducted in Department of Obstetrics and Gynaecology at BGS Global Institute of Medical Sciences, Bengaluru. 100 Women with late term pregnancy who fulfilled the inclusion and exclusion criteria were considered for the study after an informed written consent.Results: 73.5% (n=36) of multigravida and 80.4% (n=41) of prim gravida showed improvement in the Bishop score post induction with mifepristone and majority (89.79 % primigravida and 84.31% multigravida) of the study population had vaginal delivery. Multigravida (73.5%) had less induction delivery interval (less than 48hours) compared to primigravida (19.6%).Conclusions: Mifepristone, a progesterone antagonist causes a significant improvement in the Bishop’s score and is associated with an increased rate of vaginal deliveries.
ABSTRACT
Background: To compare the efficacy for pre–induction cervical ripening with Foley catheter vs PGE2 in elective induction Materials and Methods: The study group consisted of 100 antenatal women admitted for safe institutional delivery and who required pre–induction cervical ripening. Labour was induced in 50 women with Foley catheter and remains 50 women with similar inclusion criteria with 0.5gms Dinoprostone gel and efficacy of both method is compared. Results: The induction to vaginal delivery interval in the Foley group was 9.8hrs and 12.5hrs with the Dinoprostone group. Rate of vaginal deliveries was 78% in Foley group and 64% in Dinoprostone group respectively. Caesarean delivery rate was 22% and 36% in Foley group and Dinoprostone group respectively maternal side effects tachysystole, vomiting, diarrhoea, post pasture haemorrhage higher with Dinoprostone groups. Conclusions: Foley catheter I safer, easier, cheaper, effective method of pre–induction cervical ripening.
