UNLABELLED: The purpose of this study was to evaluate the proportion of indicated preterm births among all preterm births in a type 3 maternity ward; to assess practices in terms of mode of delivery in such cases; and to analyse the observed outcomes for such deliveries.
MATERIALS AND METHODS: A retrospective study was conducted in the obstetrics department of the regional university hospital of Tours (type 3 maternity ward) over a 22-month period. Women with an indicated preterm birth between 22 and 37 weeks of gestation, for whom vaginal delivery was possible, were included in the study. For every woman, the choice of mode of delivery (caesarean before labour or induction of labour) as well as maternal, obstetrical and neonatal factors were recorded.
RESULTS: From January 2012 to October 2013, 539 deliveries were preterm among which 42.5% were indicated preterm births. Out of 114 women for whom vaginal delivery was possible, 33.3% had a caesarean before labour and 66.7% had an induction of labour. The choice of mode of delivery is influenced by various factors such as local conditions, gestational age and type of obstetrical pathologies. Moreover, birth weight and Apgar score are significantly lower and the hospitalisation rate of newborns is significantly higher in the "caesarean before labour" group.
CONCLUSION: Indicated preterm births represent almost half of preterm births in the maternity ward. A third of these indicated preterm births were caesareans before labour. Due to the neonatal morbidity resulting from indicated preterm birth, it is essential to regularly reassess indications of indicated preterm birth.
