[Ab] Abstract:Non-pulsatile oxytocin given during labour can negatively affect breastfeeding. The aim of this study was to assess whether intrapartum oxytocin administration has any effect on breastfeeding. Secondly, to assess whether some maternal or neonatal variables influence breastfeeding. A retrospective cohort study was done, comparing two groups: women exposed (n = 101) and not exposed to oxytocin (n = 100) during labour. Women with caesarean section, vacuum extraction/forceps, twin pregnancy, breech presentation, premature neonates and with an Apgar score <7 at 5 minutes were excluded. Duration of breastfeeding was evaluated by a phone call interview. A regression analysis was done, evaluating possible confounding factors. The use of oxytocin during labour was demonstrated to be a predictor of impaired first hour breastfeeding (OR =2.493, CI: 1.05-5.92; p = .038). At three months' postpartum, 26.7% women in the exposed group versus 14% in the non-exposed group were not breastfeeding (p = .035). This result was not statistically significant when adjusting for possible confounders. High pregestational body mass index was the best predictor of an impaired third month's postpartum breastfeeding (OR =0.901, CI: 0.835-0.972; p = .007). Intrapartum oxytocin administration could inhibit first hour breastfeeding. A novel association was detected, pregestational body mass index was a predictor of impaired breastfeeding at three months, possibly confounding the oxytocin effect. Additional prospective studies are needed to investigate potential associations between intrapartum oxytocin and breastfeeding. Impact statement What is already known on this subject? Oxytocin is a common medical intervention during labour. Some studies suggest a negative association between intrapartum oxytocin dose, newborn sucking and an increased risk of early breastfeeding discontinuation. However, some maternal variables were not considered in these studies and the impact synthetic oxytocin may have on breastfeeding has not been thoroughly researched. What do the results of this study add? In this study, intrapartum oxytocin administration seems to inhibit the first hour breastfeeding. However, a novel association was detected, high pregestational body mass index was a predictor of impaired breastfeeding at three months, possibly confounding oxytocin effects. What are the implications of these findings for clinical practice and/or further research? Additional prospective studies are needed to investigate potential associations between intrapartum oxytocin and breastfeeding. Therefore, health care professionals should help obese women, starting from conception, to maximise breastfeeding outcomes as much as possible.

[Ab] Abstract:INTRODUCTION: Breech presentation and twin pregnancy are regarded as stressful situations for medical staff. This stress is often associated with an increased likelihood of intervention during labor - especially when the on-shift obstetrician lacks experience. MATERIAL AND METHODS: We performed a 2-year prospective, observational study of cesarean section (CSDs) and assisted vaginal (AVDs) deliveries in a tertiary maternity unit for attempted vaginal deliveries of breech presentations and twin pregnancies. The obstetric management decisions taken by a group of four registrars were compared with those taken by a group of 11 experienced obstetricians. Changes over time in practice were also monitored. RESULTS: Registrars managed 66 and 52 breech presentations and twin pregnancies respectively (30 and 27 in the experienced group). Groups' neonatal outcomes were similar. There were no intergroup differences in proportions of CSDs for either breech presentations (25 [37.5%] vs. 15 [50%] in the registrar and experienced groups, respectively; p=0.26) or twin pregnancies (11 [21.1%] vs. 6 [22.2%], respectively; p=0.91) or in proportion of AVDs for twin pregnancies (41 [78.8%] vs. 21 [77.8%], respectively; p=0.91). Proportions of CSDs for breech presentation and AVDs for twin pregnancies did not change over time in either group. However, proportion of CSDs for twin pregnancies increased over time in the registrar group (p=0.004). DISCUSSION: Well-trained registrars appeared to have acquired the skills required to safely manage an obstetric ward; this pleads to maintain clinical practice during residency to preserve low CSD and AVD rates.

[Ab] Abstract:BACKGROUND: The Ten Group Classification System (TGCS) allows critical analysis according to the obstetric characteristics of women in labor: singleton or multiple pregnancy, nulliparous, multiparous, or multiparous with a previous cesarean delivery, cephalic, breech presentation or other malpresentation, spontaneous or induced labor, and term or preterm births. Labor outcomes associated with epidural analgesia may be different among the different labor classification groups. The aim of this study was to explore associations between epidural analgesia and cesarean delivery, and epidural analgesia and assisted vaginal delivery, in women classified using the TGCS. METHODS: Slovenian National Perinatal Information System data for the period 2007-2014 were analyzed. All women after spontaneous onset or induction of labor were classified according to the TGCS, within which cesarean and vaginal assisted delivery rates were investigated (P <0.003 significant). RESULTS: Data on 207 525 deliveries (and 211 197 neonates) were analyzed. In most TGCS groups women with epidural analgesia had lower cesarean delivery rates. Women in group 1 (nulliparous term women with singleton fetuses in cephalic presentation in spontaneous labor) with epidural analgesia had a higher cesarean delivery rate. In most TGCS groups women with epidural analgesia had higher assisted vaginal delivery rates. CONCLUSION: Epidural analgesia is associated with different effects on cesarean delivery and assisted vaginal delivery rates in different TGCS groups.

[Ab] Abstract:OBJECTIVES: The aim of this study was to estimate the effects of risk factors on elective and emergency caesarean section (CS) and to estimate the between-hospital variation of risk-adjusted CS proportions. DESIGN: Historical registry-based cohort study. SETTINGS AND PARTICIPANTS: The study was based on all singleton deliveries in hospital units in Denmark from January 2009 to December 2012. A total of 226 612 births by 198 590 mothers in 29 maternity units were included. PRIMARY AND SECONDARY OUTCOME MEASURES: We estimated (1) OR of elective and emergency CS adjusted for several risk factors, for example, body mass index, parity, age and size of maternity unit and (2) risk-adjusted proportions of elective and emergency CS to evaluate between-hospital variation. RESULTS: The CS proportion was stable at 20%-21%, but showed wide variation between units, even in adjusted models. Large units performed significantly more elective CSs than smaller units, and the risk of emergency CS was significantly reduced compared with smaller units. Many of the included risk factors were found to influence the risk of CS. The most important risk factors were breech presentation and previous CS. Four units performed more CSs and one unit fewer CSs than expected. CONCLUSION: The main risk factors for elective CS were breech presentation and previous CS; for emergency CS they were breech presentation and cephalopelvic disproportion. The proportions of CS were stable during the study period. We found variation in risk-adjusted CS between hospitals in Denmark. Although exhaustive models were applied, the results indicated the presence of systematic variation between hospital units, which was unexpected in a small, well-regulated country such as Denmark.

[Ab] Abstract:Objetives: To analyze the rate of successful external cephalic versions in our center and caesarean sections that would be avoided with the use of external cephalic versions. Material and methods: From January 2012 to March 2016 external cephalic versions carried out at our center, which were a total of 52. We collected data about female age, gestational age at the time of the external cephalic version, maternal body mass index (BMI), fetal variety and situation, fetal weight, parity, location of the placenta, amniotic fluid index (ILA), tocolysis, analgesia, and newborn weight at birth, minor adverse effects (dizziness, hypotension and maternal pain) and major adverse effects (tachycardia, bradycardia, decelerations and emergency cesarean section). Results: 45% of the versions were unsuccessful and 55% were successful. The percentage of successful vaginal delivery in versions was 84% (4% were instrumental) and 15% of caesarean sections. With respect to the variables studied, only significant differences in birth weight were found; suggesting that birth weight it is related to the outcome of external cephalic version. Probably we did not find significant differences due to the number of patients studied. Conclusion: For women with breech presentation, we recommend external cephalic version before the expectant management or performing a cesarean section. The external cephalic version increases the proportion of fetuses in cephalic presentation and also decreases the rate of caesarean sections.

[Ab] Abstract:BACKGROUND: Management of noncephalic second twin delivery rests on the results of population-based retrospective studies of twin births that have shown higher neonatal mortality and morbidity for second twins with noncephalic, compared with cephalic, presentations after vaginal delivery of the first twin. Because these studies are flawed by data of questionable validity, do not report the obstetrical practices at delivery, and do not allow collection of potential confounding variables, we performed a national prospective study specially designed to evaluate the management of twins' delivery. OBJECTIVE: We sought to assess neonatal mortality and morbidity according to second twin presentation after vaginal birth of the first twin. STUDY DESIGN: The Jumeaux Mode d'Accouchement study was a nationwide prospective population-based cohort study of twin deliveries performed in 176 maternity units in France from February 2014 through March 2015. The primary outcome was a composite of intrapartum mortality and neonatal mortality and morbidity. Neonatal outcomes of second twins born ≥32 weeks of gestation after vaginal delivery of the first cephalic or breech twin were compared according to the noncephalic or cephalic second twin presentation. Multivariable logistic regression models controlled for potential confounders. Subgroup analyses were conducted according to the breech or transverse presentation of the noncephalic second twin, and gestational age at delivery, before or after 37 weeks of gestation. RESULTS: Among 3903 second twins enrolled in the study, 2384 (61.1%) were in cephalic and 1519 (38.9%) in noncephalic presentations, of whom 999 (25.6%) were in breech and 520 (13.3%) in transverse presentation. Composite neonatal mortality and morbidity did not differ between the noncephalic and cephalic group (47/1519 [3.1%] vs 59/2384 [2.5%]; adjusted odds ratio, 1.23; 95% confidence interval, 0.81-1.85). No significant difference between groups was shown for the primary outcome in subgroup analyses according to type of noncephalic second twin presentation or gestational age at delivery. Cesarean delivery rates for the second twin were lower in the breech than in the cephalic group (14/999 [1.4%] vs 75/2384 [3.1%], P = .003) and lower in the cephalic than in the transverse group (75/2384 [3.1%] vs 35/520 [6.7%], P < .001). CONCLUSION: Noncephalic and cephalic second twin presentations after vaginal delivery of the first twin ≥32 weeks of gestation are associated with similar low composite neonatal mortality and morbidity. Vaginal delivery of noncephalic second twin is a reasonable option.

[Ab] Abstract:OBJECTIVES: Few studies have assessed the impact of induction of labor on breech presentation. This study aims to summarize the effect of induction of labor of breech presentation on perinatal morbidity. METHODS: Literature review was done in Medline, Embase, Web of science and Cochrane Library up to 20 October 2017. Randomized control studies, cohort studies, and case control publishing studies comparing induction of labor versus spontaneous labor of singleton live breech birth were included. Perinatal morbidity was calculated by RevMan 5 and presented by pooled odds ratio with 95% confidence intervals. RESULTS: Cesarean section rate and neonatal intensive care unit admission were increased in induction of breech labor as compared with spontaneous breech labor. No significant difference in umbilical cord blood base excess ≤ -12 mmol/L, Apgar 5 min < 7, Apgar 5 min < 4, umbilical cord blood PH < 7, neonatology unit admission, maternal fever, and intrapartum stillbirth between the two groups was found. CONCLUSIONS: Induction of breech labor has higher cesarean section rate and NICU perinatal morbidity compared to spontaneous breech labor. The neonatal outcomes were otherwise similar across both groups. Eligibility for induction of breech labor needs to be assessed carefully according to individual situation.

[Ab] Abstract:INTRODUCTION: In 2016, 22.0% of deliveries in France were induced. The current lack of high level of evidence data about the methods and indications for induction of labour has promoted heterogeneous and non-recommended practices. The extent of these different practices is not adequately known in France today, although they may influence perinatal outcomes. The objective of this study was to report current practices of induction of labour in France. MATERIAL AND METHODS: This study surveyed 94 maternity units in seven perinatal networks. A questionnaire was sent by email to either the department head or delivery room supervisor of these units to ask about their methods for induction and their attitudes in specific obstetric situations. RESULTS: The rate of induction varied between maternity units from 7.7% to 33% of deliveries. Most units used two (39.4%) or three or more (35.1%) agents for cervical ripening. In all, 87 (92.6%) units reported using dinoprostone as a vaginal slow-released insert, 59 units dinosprostone as a vaginal gel (62.8%) and 46 units a balloon catheter (48.9%). Only three units reported using vaginal misoprostol. Inductions without medical indication were reported by 71 (75.5%) maternity units, and 22 (23.4%) units even when the cervix was unfavourable. Obstetric attitudes in cases of breech presentation, previous caesareans, fetal growth restriction or macrosomia and prelabour rupture of the membranes varied widely. DISCUSSION: The variability of practices for induction of labour and the persistence of disapproved practices call for an assessment of the effectiveness and the safety of the different strategies.

[Ab] Abstract:Little information exists about socio-economic, environmental or occupational determinants of low Apgar scores among Nigerian neonates. Mothers in lying-in wards of four hospitals in Ibadan were interviewed on socio-demographic characteristics, obstetric history and work activities during index pregnancy. Apgar scores and clinical data were extracted from case notes. Of the 1349 respondents, 20% had Apgar score <7 at one minute, 4% at five minutes. Lower education, cooking with kerosene, physical exertion at work, nulliparity, hypertension in pregnancy, prolonged rupture of membranes, breech presentation and caesarean section were predictors for low Apgar scores at one minute; nulliparity, male infant and breech presentation at five minutes. Occupations with lower socio-economic status or those requiring physical exertion; tailoring, catering and hairdressing recorded higher rates of low Apgar scores at one minute (p = .08). Physical exertion at work and cooking with kerosene may be predictive of low Apgar scores and require further study.
