| description | Introduction: Induction of labour is commonly performed in clinical practice. Increasing rates of induction of labour worldwide has led to debate on whether elective induction improves the outcomes or simply leads to increased complications and healthcare costs. Maternal and neonatal complications and increased caesarean section (CS) rates associated with induction of labour are related to a variety of factors influencing the methods of induction. Misoprostol has been the drug of choice for induction of labour in developing countries for almost a decade. Different misoprostol regimens are used for induction of labour in different health facilities. New Somerset Hospital uses the standard protocol for induction of labour using misoprostol that the Western Cape Government adopted. This protocol has however not been audited. The main objective of the study was to determine the maternal and fetal outcomes of inductions of labour performed at New Somerset Hospital. Methods: This was a retrospective study conducted at New Somerset Hospital. We reviewed a random sample of medical records of patients who underwent induction of labour from 01 January 2014 to 31 December 2014. Ethics committee approval was granted by the Human Research Ethics Committee of the Faculty of Health Sciences of UCT. A total of 88 folders were sampled from 1029 women who had induction of labour. Results: There were a total of 6514 deliveries in 2014 of which 1029 had induction of labour, giving an induction rate of 15.8%. A total of 86 patients were included in the study. The mean age of the patients was 28.9 years (SD±6.586) with an age range of 16 to 44 years. The average gestational age at the time of induction of labour was 39.5 weeks with a range 35 to 42.6 weeks and 14.0% of the patients were HIV positive. The three main indications of induction of labour were hypertension in pregnancy (40.7%), prolonged pregnancy (27.9%) and pre-labour rupture of membranes (8.1%). Overall, 50 patients (58.1%) had vaginal delivery and 36 patients (41.9%) had caesarean delivery. There was a significant association between mode of delivery and time to delivery. Patients who delivered within 24 hours of commencement of induction of labour were more likely to have had a vaginal delivery (p = 0.005). The three main indications for caesarean delivery were fetal heart rate changes (n=30; 72.0%) followed by failed induction of labour (n=9; 21.0%) and cephalopelvic disproportion (n=3; 7.0 %). In terms of maternal outcomes, 2 patients (2.3%) had hyperstimulation of the uterus, 6 patients (7.0%) had postpartum hemorrhage, 8 patients (9.3%) had vaginal tears and 5 patients (5.9%) had an episiotomy performed during delivery. The mean birth weight was 3262.1g (SD±503.77) with a range of 1925 to 4515 grams. At five minutes the means Apgar score was 9.8(SD ± 0.62) with range of 6 to 10. A total of 38 babies (44.3%) had meconium stained liquor documented at delivery, three babies (3.4%) required neonatal resuscitation upon delivery. There were 10 (11.6%) babies that were admitted to NICU. Conclusion: In this study we found that the prevalence of induction of labour was 15.8%. Hypertension in pregnancy, prolonged pregnancy and pre-labour rupture of membranes are the three common indications for induction of labour. Successful vaginal delivery was achieved in 51.0% of the study population. The caesarean delivery rate was high, mostly due to CTG changes The current induction of labour protocol using oral misoprostol is associated with acceptable maternal and fetal outcomes. |
