The Fetomaternal Outcome of Induction of Labour in Idiopathic Oligohydramnios

Objective: To assess fetomaternal outcome of induction of labour in patients with idiopathic oligohydramnios at ANTH to reduce the morbidity associated with increased cesarean section rate and deliver alive healthy babies. Methodology: This quasi experimental study was conducted in the department of Obstetrics & Gynecology, Alsuffah hospital Rawalpindi and Akbar Niazi Teaching Hospital, Islamabad, over a period of six months from June to Dec 2022. A detailed history was taken followed by a thorough general physical examination and obstetric examination. Routine investigations were performed along with obstetrical ultrasonography. CTG was performed and after ensuring a reactive trace along with no contraindication to vaginal delivery; were offered option of induction of labour after informed consent on predesigned consent form with tab. prostin E2 3mg maximum of two doses with 6 hours apart via vaginal route as per induction of labour protocol at 37 weeks or beyond and were followed-up in OPD till postnatal follow up after 1 week. Results: The mean age of the patients was 26.85 ± 0.46 years. Majority 30 (41.1%) of the patients had parity of 3 or more and most 31 (42.47%) of the females in the study were given induction of labor at 39 weeks’ gestation followed by 27 (36.99%) were given IOL at 38 weeks. The mean value of the amniotic fluid index was 4.35 ± 1.84. Main bulk 34 (46.58%) of the females delivered with cesarean section and most common indication for cesarean section Pathological CTG in 15 (20.55%) patients. Mean birth weight was recorded to be 3.25 ± 0.86 kg and about one third of the babies, 24 (32.88%) babies required admission in NICU. A large number 31 (42.47%) of the children had low APGAR score (< 7) at 5 minutes. Conclusions: The development of foetal distress, meconium-stained liquor, caesarean delivery rates, NICU admission rates, and low birth weight are all linked to pregnancies with isolated oligohydramnios.
