Abstract
INTRODUCTION: Induction of labour can be defined as an intervention intended to artificially initiate uterine contractions resulting in progressive effacement and dilation of cervix to enable vaginal delivery. The more common indications include post term pregnancy, gestational hypertension, oligohydramnios, etc. AIM OF THE STUDY: The aim of the study is to estimate the effects of Hygroscopic dilators in ripening of uterine cervix and to compare the effects of Hygroscopic dilators and Foley catheter in the induction of labour in terms of cervical dilatation, induction delivery interval, maternal and fetal outcome. MATERIALS AND METHODS: The Prospective study was conducted in Govt. RSRM Lying in Hospital, Chennai during the period of December 2018 to September 2019. 120 patients who were term antenatal mothers eligible for induction of labour were selected and bishop score assessed. If the bishop score was less than 6, they were divided into hygroscopic dilator group and foleys group randomly. Patient characteristics and outcome were analyzed and compared between hygroscopic group and foleys group. Primary outcome of this study was mode of delivery. Secondary outcome like post induction bishop score, induction delivery interval, apgar at 1 min and 5 min, requirement of PGE2 gel were measured and analyzed. RESULTS: Among the study group 73.3% of patients had labour natural compare to 71.7% in the control group (p value = 0.838). Overall vaginal delivery rate including operative vaginal delivery was 80% in Study group and 73.4% in Control group. Emergency LSCS done in 20% in study group whereas 26.7% in control group (p value = 0.387). Hence there is no statistically significant difference in primary outcome between study group and control group. Induction delivery interval for primigravida was 12 to 24 hours in 77.1% cases in study group and more than 24 hours in 60.5% cases in control group (p value = 0.025). Induction delivery interval for multigravida is 12 to 24 hours in study group in 80% cases whereas in study group 12 to 24 hours in 40.9% cases and more than 24 hours in 40.9% cases. No PGE2 gel was used in 31.7% of cases in control group and 10% cases in study group. In study group 1 gel was used in 76.7%, two gel were used in 11.7% cases and 3 gel were used in 1.7% cases. In control group, 1 gel was used in 36% cases, two gel were used in 5% cases. Requirement for PGE 2 gel is higher in study group than control group which is statistically significant.There is no statistically significant difference in 1 min and 5 min apgar score between study group and control group (p value = 0.120). There is statistically significant difference in higher post insertion bishop score in study group compared to control group (p value = 0.033). CONCLUSION: Dilapan S is safe, effective induction method at term with outcome comparable to foleys balloon catheter in the induction of labour.
