To examine the prevalence across 25 years of overweight and obesity among nulliparous Australian women during early pregnancy; to estimate proportions adverse perinatal outcomes attributable in this population.Cohort study; retrospective analysis electronic maternity data. Setting, participants: 42 582 with singleton pregnancies giving birth at Royal Prince Alfred Hospital, an urban teaching hospital Sydney, January 1990 - December 2014.Maternal body mass index (BMI), socio-demographic...
Objectives To prepare more accurate population-based Australian birthweight centile charts by using the most recent population data available and excluding pre-term deliveries obstetric intervention of small for gestational age babies. Design Population-based retrospective observational study. Setting Institute Health Welfare National Perinatal Data Collection. Participants All singleton births in Australia 23–42 completed weeks' gestation with spontaneous onset labour, 2004–2013. Births...
Objective: Early detection of hypoxic−ischaemic encephalopathy (HIE) in neonates is critical. We conducted a pilot cohort study to determine the feasibility collecting umbilical cord blood samples for neurofilament light (NfL) and assess association NfL with non−reassuring fetal status other biomarkers. Design: Prospective study. Setting: A single, large tertiary quaternary referral hospital. Patients: 108 maternal participants consenting donate blood. Intervention: Umbilical venous plasma...
Objectives To assess the impact of occipito‐posterior position in second stage labour on operative delivery. Methods Double‐blinded prospective cohort study ultrasound determined occiput‐posterior during compared with occiput‐anterior position. The primary outcome was (caesarean section, forceps or vacuum) Results A total 68% (13/19) women group, and 27% (39/141) group had an delivery (unadjusted: P < 0.001). Caesarean section performed 37% 5%, respectively ( a longer (mean 2 h 59 minutes...
Abstract Introduction The cesarean delivery rate has been increasing globally in recent decades. reasons for this are complex and subject to ongoing debate. Investigation of the indications how these have changed over an extended period time could provide insight into changing obstetric practice. Our objective was explore contributing factors by examining incidence past three decades at our institutions. Material methods We conducted a retrospective observational study all deliveries, from...

Of staff, 50% ward nurses, 71% doctors, this type injury during previous two...
Background There is emerging evidence that caesarean section at full dilatation associated with an increased risk of subsequent spontaneous preterm birth. Aim To investigate the association between and birth in pregnancies. Materials methods This was a retrospective cohort study women who had two consecutive births Royal Prince Alfred Hospital, 1989–2015. Our main comparison group emergency sections during first stage labour. Secondary groups were elective sections, instrumental deliveries...

Complications classified as minor (transient cardiotocography abnormalities, ruptured membranes, small antepartum haemorrhage) or serious (fetal...
About half of Australian women have a body mass index in the overweight or obese range at start pregnancy, with serious consequences including preterm birth, gestational hypertension and diabetes, caesarean section, stillbirth, childhood obesity. Trials to limit weight gain during pregnancy had limited success reducing before has greater potential improve outcomes. The PreBabe Pilot study was randomised controlled pilot trial assess feasibility, acceptability loss achieved using commercial...
Occiput posterior position is the most common malpresentation in labour, contributes to about 18% of emergency caesarean sections and associated with a high risk assisted delivery. Caesarean section now major contributing factor maternal mortality morbidity following childbirth developed countries. Obstetric intervention by forceps ventouse delivery complications genital tract neonate, respectively. There level 2 evidence that prophylactic manual rotation reduces rate vaginal But there has...
Aim To determine the feasibility of a multicentre randomised controlled trial ( RCT ) to investigate whether digital rotation fetal head from occiput posterior OP position in second stage labour reduces risk operative delivery (defined as caesarean section CS or instrumental delivery). Methods We conducted study between December 2010 and 2011 tertiary referral hospital Australia. A transabdominal ultrasound was performed early on women with cephalic, singleton pregnancies position. Those...
Background There is global concern about rising caesarean section rates. Identification of risk factors could lead to preventative measures. Aims To describe the association between neonatal head circumference and (i) for failure progress, (ii) intrapartum overall. Materials Methods This was a retrospective cohort study 11 687 singleton live births with cephalic presentation, attempted vaginal birth at least 37 completed weeks gestation from January 2005 June 2009.
