Objective: To review rates of and indications for late pregnancy feticide at a major Queensland tertiary perinatal centre over the past decade., Design: Retrospective cohort study., Setting, Participants: The Centre for Advanced Prenatal Care at the Royal Brisbane and Women's Hospital, a tertiary perinatal centre; feticides of singleton pregnancies of at least 22 weeks' gestation, 1 January 2010 - 31 December 2020., Main Outcome Measures: Indications for feticide; median gestational age at feticide; referral source; time between referral, maternal-fetal medicine review, and feticide., Results: During 2010-2020, 305 feticides were undertaken at 22 weeks' gestation or later. The annual number of feticides increased from 20 in 2010 to 54 in 2020. The median gestational age at feticide was consistent across the decade (24 +6 weeks; range, 17 +0 to 37 +1 weeks). The most frequent fetal indications for feticide were neurological abnormalities (110 of 305, 36%), aneuploidy or genetic syndromes (67, 22%), and cardiac malformations (59, 19%). Most women were seen for review within seven days of referral for feticide (154 of 197 for whom this information was available, 78%; median, five days; range, 0-34 days), and 136 of 197 feticides (69%) were undertaken within seven days of the initial maternal-fetal medicine review., Conclusions: Most late pregnancy feticides were performed because of fetal indications, primarily structural malformations or genetic abnormalities. Despite advances in prenatal imaging and diagnosis, late termination of pregnancy remains a necessary option in some pregnancies with maternal or fetal indications, and equitable access to late termination of pregnancy services is a vital component of reproductive health care., (© 2022 AMPCo Pty Ltd.)

Objectives: This study aimed to investigate the role of prolonged second stage of labour and second stage caesarean section on the risk of spontaneous preterm birth (sPTB) in a subsequent pregnancy., Methods: This was a retrospective cohort study of nulliparous women with two consecutive singleton deliveries between 2014 and 2017 at a tertiary centre. In the vaginal delivery cohort, subsequent pregnancy outcomes for women with a prolonged second stage (>2 h) were compared with those with a normal second stage (≤2 h). In the caesarean delivery cohort, women with a first stage or a second stage were compared with the vaginal delivery cohort. The primary outcome was subsequent sPTB., Results: A total of 821 women met inclusion criteria, of which 74.8% (614/821) delivered vaginally and 25.2% (207/821) delivered by caesarean section. There was no association between a prolonged second stage in the index pregnancy and subsequent sPTB (aOR 0.70, 95% CI 0.13-3.83, p=0.7). The risk of subsequent sPTB was threefold for those with a second stage caesarean section; however this did not reach statistical significance., Conclusions: A prolonged second stage of labour in the index pregnancy is not associated with an increased risk of subsequent sPTB. A second stage caesarean section in the index pregnancy may be associated with an increased risk of subsequent sPTB, however there was no statistically significant difference. These findings are important for counseling and suggest that the effects of these factors are not clinically significant to justify additional interventions in the subsequent pregnancy., (© 2020 Cathy Z.

Background: Preterm breech delivery is associated with a higher perinatal mortality rate compared with preterm vertex delivery, and some studies suggest caesarean section leads to lower mortality rates. Few studies include infants delivered less than 26 weeks gestation, and where included, results are often not stratified by gestational age. There is also a lack of consistent reporting on neonatal and maternal morbidity outcome measures., Aims: To determine if mode of delivery for singleton extreme preterm breech fetuses is associated with a difference in perinatal mortality, neonatal and maternal morbidity., Materials and Methods: Retrospective cohort study of breech deliveries from 23 + 0 to 27 + 6 weeks gestation (extreme preterm) between 2005 and 2014 at a tertiary obstetric facility., Results: One hundred and fifty deliveries met the selection criteria. Perinatal mortality was reduced in the caesarean section group (20% vs 55.5% P < 0.001). Apgar scores ≥ 7 (P = 0.008) and cord pH ≥7.1 (P = 0.025) were more likely for neonates delivered by caesarean section, with lower rates of birth trauma (P = 0.003). Caesarean section was associated with higher nursery admission rates (P < 0.001), longer intensive care nursery admission (P = 0.006), continuous positive airway pressure times (P = 0.008) and increased use of surfactant (P < 0.001). Maternal morbidity was increased with caesarean section including longer hospital stay (P < 0.001), higher postpartum haemorrhage (P < 0.001) and wound infection rates (P = 0.034)., Conclusion: Caesarean section for singleton extreme preterm breech delivery is associated with reduced perinatal mortality, improved neonatal condition at delivery, and increased short-term maternal morbidity., (© 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)
