TO STUDY THE FETO-MATERNAL OUTCOME IN OCCIPITO-POSTERIOR POSITION.
INTRODUCTION: Childbirth is considered as one of the most rewarding and memorable experience in a woman’s life.Labour is the process that leads to childbirth. Difficult labour characterized by abnormally slow labour progress is known as dystocia. Malposition refers to any position of the vertex other than flexed occipito- anterior one. It is a common obstetric belief that progression of labour is underpinned by fetal position. MATERIAL AND METHODS: 100 term antenatal patients, 50 with occipito-posterior and 50 with occipito-anterior position were included in the study admitted in labour room from December 2015 to March 2017. After recuirtment of patients, detailed history, examination: general physical, per abdominal and per vaginal was done. All patients underwent ultrasonography to confirm the fetal position at the onset of labour. They were then followed up until birth to determine outcome. The primary outcome measures including mode of delivery which was categorized into vaginal delivery, instrumental delivery and Cesarean section, duration of labour and neonatal outcome. RESULTS: Of the total 100 cases, the proportion of vaginal delivery was more in occipito-anterior group (74%) in comparison with occipito-posterior group (42%). 40% patients of occipito-posterior group landed into cesarean delivery against 18% patients of occipito-anterior group. Eight percent patients had face to pubis delivery. The mean duration of labour is prolonged in study group i.e. 473.2±1.84 minutes in first stage, 29.4±7.67 minutes in second stage and 5.70±1.75 minutes in third stage versus i.e. 376.8±1.26 minutes in first stage, 24.79±9.77 minutes in second stage and 5.20±3.22 minutes in third stage of labour of control group. The neonatal outcome was analysed by Apgar score at 1,5 minutes of delivery, presence of caput succedaneum and moulding and found to be comparable in both the groups. CONCLUSION: We found that malposition group showed prolongation of labour in comparison to occipito-anterior position. We found high rate of cesarean delivery in study group because of preference for cesarean over instrumental delivery. Neonatal outcome were comparable in both the groups. We noted few instrumental deliveries owing to the fact that art of instrumental delivery is dying in modern obstetrics.
