Comparing forces on the fetal neck in breech delivery in lithotomy versus all-fours position: a simulation model.

PURPOSE: To measure forces applied to the fetal neck, in a simulation model for breech delivery, in both lithotomy versus all-fours position. METHODS: We used a Laerdal SimMom simulator and a Birthing Baby together with PROMPT Flex Software. The descent of the fetus was accomplished using the Automatic Delivery Module 2. The baby was always in breech position; the SimMom in either all-fours or lithotomy positions. Sensors were located inside the fetal neck region to simulate forces applied to the plexus. RESULTS: The lowest force on the fetal neck region was recorded for the delivery in all-fours position without further maneuvers (mean force 58.70 Newton, standard deviation 2.54 N). As weight was added to the baby, the force increased (i.e. + 500 g, mean force 71.8 N, SD 3.08 N, p < 0.001). Delivery in lithotomy position resulted in a mean force of 81.56 N (SD 19.55 N). The force significantly increased in case of delivery of the head without assistance from contractions (mean force 127.93 N, SD 23.10 N). In all-fours position, the delivery of the fetal head from pelvic floor level without contractions (Frank's Nudge maneuver) resulted in a mean force of 118.45 N (SD 15.48 N, p = 0.02). Maneuvers for shoulder dystocia (the inverted type that can occur during breech delivery) led to significantly higher mean forces independent from birthing positions. CONCLUSION: Breech delivery in all-fours position was associated with the lowest force acting on the fetal neck in our simulation model.

External cephalic version in the outpatient clinic.

The continuous increase in the rates of cesarean section worldwide is concerning. Breech presentation is one of the major indications for cesarean section in most countries. External cephalic version (ECV) can reduce cesarean rates by approximately two-thirds in term breech pregnancies. After introduction of ultrasonography and cardiotocography before and after the procedure, ECV has become much safer. As a result, over-night fasting, intravenous access, and preoperative laboratory tests are no longer recommended as the patient's risk of requiring emergency cesarean section is very low. We have been running the largest ECV clinic in South Korea since 2008, and ECV trials in the outpatient clinic were started in 2015. We want to share our experiences running the ECV clinic for 15 years managing more than 2000 patients.

Caesarean section rates: applying the modified ten-group Robson classification in an Australian tertiary hospital.

The aim of this study was to determine the main contributors to caesarean section (CS) rates at an Australian tertiary hospital. We conducted a retrospective review of women who delivered in an Australian tertiary hospital between 2014 and 2017. Women were allocated according to a modified Robson Ten-Group Classification System and CS indications were collected in nulliparous women and women with previous CS. The largest contributor to the 35.7% overall CS rate was women with a term cephalic infant and a previous CS (31.5% relative CS rate) and the most common indication was repeat CS. The group CS rate in nulliparous women with a cephalic term infant was higher when labour was induced compared to occurring spontaneously (36.6% and 18.1% respectively). The primary CS indication for these women was labour dystocia and maternal request was the most common CS indication for nulliparous women with a pre-labour CS.IMPACT STATEMENTWhat is already known on this subject? Significantly increasing caesarean section (CS) rates continue to prompt concern due to the associated neonatal and maternal risks. The World Health Organisation have endorsed the Robson Ten-Group Classification System to identify and analyse CS rate contributors.What do the results of this study add? We have used the modified Robson Ten-Group Classification System to identify that women with cephalic term infants who are nulliparous or who have had a previous CS are the largest contributors to overall CS rates. CS rates were higher in these nulliparous women if labour was induced compared to occurring spontaneously and the primary CS indication was labour dystocia. In nulliparous women with a CS prior to labour the most common CS indication was maternal request. Majority of women with a previous CS elected for a repeat CS.What are the implications of these findings for clinical practice? Future efforts should focus on minimising repeat CS in multiparous women and primary CS in nulliparous women. This may be achieved by redefining the definition of labour dystocia, exploring maternal request CS reasoning and critically evaluating induction timing and indication. Appropriately promoting a trial of labour in women with a previous CS in suitable candidates may reduce repeat CS incidence.

Maternal and neonatal outcomes in the following delivery after previous preterm caesarean breech birth: a national cohort study.

The objective of this retrospective, nationwide Finnish population-based cohort study was to determine whether there is an association between preterm caesarean breech delivery in the first pregnancy and maternal and neonatal morbidity in the subsequent pregnancy and delivery. We identified all singleton preterm breech birth in Finland from 2000 to 2017 (n = 1259) and constructed a data set of the first two deliveries for these women. We compared outcomes of the following pregnancy and delivery among women with a previous preterm caesarean breech section with the outcomes of women with one previous vaginal preterm breech birth. p Value, odds ratio, and adjusted odds ratio were calculated. Neonates of women with a previous caesarean preterm breech delivery had an increased risk for arterial umbilical cord pH below seven (1.2% versus 0%; p value .024) and a higher rate of neonatal intensive care unit admission [22.9% versus 15% adjusted OR 1.57 (1.13-2.18); p value <.001]. The women with a previous caesarean section had a higher rate of uterine rupture (2.3% versus 0%; p value .001). They were also more likely in the subsequent pregnancy to have a planned caesarean section [19.9% versus 4% adjusted OR 8.55 (4.58-15.95), an emergency caesarean section [21.5% versus 9.7% adjusted OR 2.16 (1.28-2.18)], or an instrumental vaginal delivery [9.3% versus 3.8% adjusted OR 2.38 (1.08-5.23)].IMPACT STATEMENTWhat is already known on this subject? Vaginal birth after caesarean section is generally known to be associated with a higher risk of maternal and neonatal morbidity.What do the results of this study add? The following birth after previous caesarean preterm breech section is associated with a higher rate of uterine rupture and with a higher rate neonatal admission to the neonatal intensive care unit and more often an arterial umbilical cord pH below seven regardless of the mode of the following delivery, compared to women with a subsequent delivery after a previous vaginal preterm breech birth.What are the implications of these findings for clinical practice and/or further research? Our results must be considered when counselling patients regarding their first preterm breech delivery, as the selected method of delivery also affects the outcomes of subsequent pregnancies and deliveries.

Induction of labor in breech presentations - a retrospective cohort study.

INTRODUCTION: There is limited evidence on the safety and outcome of induction of breech labor. In this study, we aimed to compare the outcomes of spontaneous and induced breech deliveries and to describe variations in induction rates. MATERIAL AND METHODS: This was a retrospective cohort study comprising 1054 singleton live fetuses in breech presentation at Trondheim University Hospital from 2012 to 2019. The main outcome was intrapartum cesarean section, and secondary outcomes were postpartum hemorrhage, anal sphincter ruptures, Apgar scores, pH in the umbilical artery, and metabolic acidosis. All data were obtained from the hospital birth journal. RESULTS: Induction of labor was performed in 127/606 (21.0%) women with planned vaginal birth. The frequency of intrapartum cesarean section was 48.0% for induced labor vs 45.7% for spontaneous labor (P = .64). We found no differences in the frequency of postpartum hemorrhage or anal sphincter ruptures between induced and spontaneous births. The median pH in the umbilical artery was significantly lower in neonates with induced labor compared with neonates with spontaneous labor (7.22 vs 7.25; P = .02). The frequency of pH <7.05 was 7.0% for induced labor vs 2.9% (P = .05) for spontaneous labor, but the frequency of pH <7.0 was not significantly different: 2.6% vs 0.8% (P = .14), respectively. Three neonates with planned vaginal birth had metabolic acidosis: two with spontaneous labors and one with induced labor. Three fetuses with planned vaginal birth died during labor: two with spontaneous onset of labor and one with induced labor. All three were extremely preterm: two were delivered in week 23 and one in week 25. We did not observe any significant trend in induction rates in either parous or nulliparous women. CONCLUSIONS: The induction rates were stable during the study period. We did not observe any significant difference in intrapartum cesarean section rates, in the frequency of pH <7.0 in the umbilical artery, or in the frequency of metabolic acidosis when comparing induced and spontaneous breech deliveries.

Incidental intra-operative finding of a rare uterine fusion abnormality in a primigravida with breech presentation at term: A case report.

Uterine malformations are often asymptomatic but can be associated with a wide range of reproductive problems. We report a case of uterine fusion defect diagnosed intra-operatively in a 20-year-old primigravida who had elective caesarean section at term on account of breech presentation at term. Intraoperative findings included a cone-shaped uterus with narrowed fundus and the appendages emerging at the fundus and lower uterine segment on the right and left respectively. This is a rare fusion defect and makes a case for review of the existing uterine malformation classification systems, to make it all encompassing.

Value of routine ultrasound examination at 35-37 weeks' gestation in diagnosis of non-cephalic presentation.

OBJECTIVE: Undiagnosed non-cephalic presentation in labor carries increased risks for both the mother and baby. Routine pregnancy care based on maternal abdominal palpation fails to detect the majority of cases of non-cephalic presentation. The aim of this study was to report the incidence of non-cephalic presentation at a routine scan at 35 + 0 to 36 + 6 weeks' gestation and the subsequent management of such pregnancies. METHODS: This was a retrospective analysis of prospectively collected data in 45 847 singleton pregnancies that had undergone routine ultrasound examination at 35 + 0 to 36 + 6 weeks' gestation. Patients with breech or transverse/oblique presentation were divided into two groups; first, those who would have elective Cesarean section for fetal or maternal indications other than the abnormal presentation, and, second, those who would potentially require external cephalic version (ECV). The latter group was reassessed after 1-2 weeks and, if there was persistence of abnormal presentation, the parents were offered the option of ECV or elective Cesarean section at 38-40 weeks' gestation. Multivariable logistic regression analysis was carried out to determine which of the factors from maternal and pregnancy characteristics provided a significant contribution in the prediction of, first, non-cephalic presentation at the 35 + 0 to 36 + 6-week scan, second, successful ECV from non-cephalic to cephalic presentation, and, third, spontaneous rotation from non-cephalic to cephalic presentation that persisted until delivery. RESULTS: First, at 35 + 0 to 36 + 6 weeks, the fetal presentation was cephalic in 43 416 (94.7%) pregnancies, breech in 1987 (4.3%) and transverse or oblique in 444 (1.0%). Second, multivariable analysis demonstrated that the risk of non-cephalic presentation increased with increasing maternal age and weight, decreasing height and earlier gestational age at scan, was higher in the presence of placenta previa, oligohydramnios or polyhydramnios and in nulliparous than parous women, and was lower in women of South Asian or mixed racial origin than in white women. Third, 22% of cases of non-cephalic presentation were not eligible for ECV because of planned Cesarean section for indications other than the malpresentation. Fourth, of those eligible for ECV, only 48.5% (646/1332) agreed to the procedure, which was successful in 39.0% (252/646) of cases. Fifth, the chance of successful ECV increased with increasing maternal age and was lower in nulliparous than parous women. Sixth, in 33.9% (738/2179) of pregnancies with non-cephalic presentation in which successful ECV was not carried out, there was subsequent spontaneous rotation to cephalic presentation. Seventh, the chance of spontaneous rotation from non-cephalic to cephalic presentation increased with increasing interval between the scan and delivery, decreased with increasing birth-weight percentile, was higher in women of black than those of white racial origin, if presentation was transverse or oblique rather than breech and if there was polyhydramnios, and was lower in nulliparous than parous women and in the presence of placenta previa. Eighth, in 109 (0.3%) cephalic presentations, there was subsequent rotation to non-cephalic presentation and, in 41% of these, the diagnosis was made during labor. Ninth, of the total 2431 cases of non-cephalic presentation at the time of the scan, presentation at birth was cephalic in 985 (40.5%); in 738 (74.9%) this was due to spontaneous rotation and in 247 (25.1%) this was due to successful ECV. Tenth, prediction of non-cephalic presentation at the 35 + 0 to 36 + 6-week scan and successful ECV from maternal and pregnancy factors was poor, but prediction of spontaneous rotation from non-cephalic to cephalic presentation that persisted until delivery was moderately good and this could be incorporated in the counseling of women prior to ECV. CONCLUSIONS: The problem of unexpected non-cephalic presentation in labor can, to a great extent, be overcome by a routine ultrasound examination at 35 + 0 to 36 + 6 weeks' gestation. The incidence of non-cephalic presentation at the 35 + 0 to 36 + 6-week scan was about 5%, but, in about 40% of these cases, the presentation at birth was cephalic, mainly due to subsequent spontaneous rotation and, to a lesser extent, as a consequence of successful ECV.

Comparison of Nitroglycerin and Terbutaline for External Cephalic Version in Women Who Received Neuraxial Anesthesia: A Retrospective Analysis.

External cephalic version is a technique that decreases the need for cesarean delivery in patients with breech presentation. Several techniques exist to increase the success of external cephalic version; however, there are no studies comparing different tocolytics in patients who also received neuraxial anesthesia. We, therefore, performed a review of 198 patients who presented for external cephalic version and compared their success rates based on the tocolytic medication utilized. The external cephalic version success rate for patients who received terbutaline was significantly higher than for those who received nitroglycerin (N [%]: 57 [65.6] terbutaline group versus 40 [36.0] nitroglycerin group; P < .001).

Intraoperative coagulopathy during cesarean section as an unsuspected initial presentation of COVID-19: a case report.

BACKGROUND: The world's understanding of COVID-19 continues to evolve as the scientific community discovers unique presentations of this disease. This case report depicts an unexpected intraoperative coagulopathy during a cesarean section in an otherwise asymptomatic patient who was later found to have COVID-19. This case suggests that there may be a higher risk for intrapartum bleeding in the pregnant, largely asymptomatic COVID-positive patient with more abnormal COVID laboratory values. CASE: The case patient displayed D-Dimer elevations beyond what is typically observed among this hospital's COVID-positive peripartum population and displayed significantly more oozing than expected intraoperatively, despite normal prothrombin time, international normalized ratio, fibrinogen, and platelets. CONCLUSION: There is little published evidence on the association between D-Dimer and coagulopathy among the pregnant population infected with SARS-CoV-2. This case report contributes to the growing body of evidence on the effects of COVID-19 in pregnancy. A clinical picture concerning for intraoperative coagulopathy may be associated with SARS-CoV-2 infection during cesarean sections, and abnormal COVID laboratory tests, particularly D-Dimer, may help identify the patients in which this presentation occurs.

Comparison of maternal and perinatal morbidity between elective and emergency caesarean section in singleton-term breech presentation.

The objective of the study was to compare maternal and neonatal adverse outcomes between elective caesarean section (ElCS) and emergency caesarean section (EmCS) for singleton-term breech presentation. This study included women with singleton breech presentation who underwent ElCS or EmCS at term during 2007-2015 at Siriraj Hospital (Thailand). Complete data were collected for 2178 pregnant women. Of those, 1322 (60.7%) women underwent EmCS, and 856 (39.3%) delivered by ElCS. Maternal and perinatal morbidity were compared. There was no maternal or perinatal death in either group. Maternal morbidity was comparable between groups, except for longer hospital stay in the EmCS group (p = .047). One-minute Apgar score was significantly lower in the EmCS group (p = .040). There was no significant difference in 5-min Apgar score between groups. No significant difference was observed for serious maternal and neonatal morbidity between women who underwent ElCS versus those who underwent EmCS for singleton-term breech presentation.IMPACT STATEMENTWhat is already known on this subject? Emergency caesarean section (EmCS) is generally known to be associated with a higher risk of maternal and neonatal complications than elective caesarean section (ElCS).What do the results of this study add? In singleton-term breech presentation, EmCS in tertiary care setting was not associated with an increase in serious maternal and neonatal morbidity compared with EICS. Cord prolapse as an indication for emergency caesarean section was significantly associated with adverse outcomes while advanced cervical dilation ≥7 cm or low foetal station ≥+1 did not have an impact on maternal and neonatal complications.What are the implications of these findings for clinical practice and/or further research? Mean gestational age in both the ElCS and EmCS groups was approximately 38 weeks and 5 d; there were no neonatal cases with respiratory distress syndrome. Our findings suggest further prospective study in planned caesarean section scheduled for 38-39 weeks in patients with term breech presentation. The results of such a study could yield lower rates of both EmCS and potential adverse outcomes.

Increased rate of acute caesarean sections in women with epilepsy: results from the Oppland Perinatal Database in Norway.

BACKGROUND AND PURPOSE: Studies in women with epilepsy (WWE) regarding pregnancy and labour complications have disclosed contradictory results. Our purpose was to investigate whether WWE have a higher risk of acute caesarean section (CS) or pregnancy complications than women without epilepsy or women with other chronic diseases and, if we found a higher risk, to explore potential explanations. METHODS: The study used prospectively registered obstetric data from the Oppland Perinatal Database in the period 2001-2011, containing information on 18 244 births, including 110 singleton pregnancies in mothers with validated epilepsy. Data regarding epilepsy were collected retrospectively from medical records. RESULTS: Epilepsy was a significant risk factor for acute CS, breech presentation and low birth weight in offspring [odds ratio (OR), 1.93, 95% confidence interval (CI), 1.2-3.1; OR, 2.29, 95% CI, 1.2-4.6 and OR, 2.10, 95% CI, 1.0-4.2, respectively]. In multivariate logistic regression analysis, antiepileptic drug exposure was an independent risk factor for acute CS (OR, 2.00; 95% CI, 1.06-3.77) and polytherapy was a significant risk factor for breech presentation (OR, 5.37; 95% CI, 1.13-25.57). Seizure frequency during pregnancy had no influence on the complication rate. CONCLUSIONS: We found that WWE using antiepileptic drugs during pregnancy had increased rates of acute CS, breech presentation and low birth weight, and that seizure frequency during pregnancy did not influence the complication rate.

Maternal and neonatal outcome of reverse breech extraction of an impacted fetal head during caesarean section in advanced stage of labour: a retrospective cohort study.

BACKGROUND: Caesarean section with extraction of a deeply impacted fetal head is technically challenging and is associated with serious maternal and neonatal complications. The purpose of the study was to identify risks and evaluate selected outcome parameters associated with difficult fetal head extraction during caesarean section in advanced labour comparing two different extraction techniques (head pushing vs. reverse breech). METHODS: This retrospective cohort study was conducted at the Division of Obstetrics in a tertiary care hospital in Zurich, Switzerland. 629 women at term with a singleton pregnancy in cephalic presentation during advanced intrapartum caesarean section from December 2012 until December 2016 were evaluated. Primary outcome was the incidence of uterine incision extensions. Secondary outcomes were other selected maternal and neonatal outcome parameters. Data analysis was performed using SPSS with Mann-Whitney U independent sampling test and two-tailed Fisher's exact test (p < 0.01). RESULTS: Difficult fetal head extractions are associated with significantly elevated maternal and neonatal risks. When performed by reverse breech technique, significant lower rates of extensions of the uterine incision, shorter operation times and less operative blood loss were identified compared to the head pushing method. No statistically significant differences for the neonatal outcomes were described so far. However, among the group of difficult fetal delivery with the head pushing method two neonates had perinatal skull fractures, with one of those resulting in neonatal death. CONCLUSIONS: The head pushing method is associated with higher maternal morbidity than the reverse breech method for extraction of a deeply engaged fetus during intrapartum caesarean section in advanced stage of labour.

SPONSORS: The Society of Obstetricians and Gynaecologists of Canada. SUMMARY STATEMENTS: RECOMMENDATIONS: Labour Selection Criteria Labour Management Delivery Technique Setting and Consent.

Classic metaphyseal lesion of distal tibia following footling breech delivery.

Classic metaphyseal lesions associated with childbirth are rare. We report a distal tibial metaphyseal fracture following a difficult breech delivery. Classic metaphyseal fractures are considered highly specific injuries associated with non-accidental trauma. This case depicts a classic metaphyseal lesion sustained during footling breech extraction in an urgent delivery. The traction and torque placed on the distal extremities during this difficult delivery suggest a potential mechanism for this injury.

Preferred way of delivery of the impacted fetal head in cesarean sections during second stage of labor.

AIM: To compare maternal and neonatal outcomes between the 'head first' and 'legs first' delivery methods during a second stage cesarean section. METHODS: We conducted a retrospective study between January 2009 and May 2015 at a large public university tertiary referral center. Included were all women who underwent cesarean delivery with a fully dilated cervix and a fetal head at the level of the ischial spines or below. The study population was divided into two groups according to way of fetal delivery: The 'legs first' (reverse breech) method and the 'head first' method. Demographics and maternal and fetal outcomes were retrieved for both groups. RESULTS: During the study period 447 women underwent a cesarean section while their cervix was fully dilated. Of them, 321 met the inclusion criteria: One hundred and twenty-one (38%) were delivered using the 'legs first' method and 200 (62%) were delivered using the 'head first' method. Indication for surgery and fetal head station was similar for both groups. While no difference in overall intraoperative uterine incision extension rate was observed, a higher rate of uterine incision extension was demonstrated in the 'head first' group in cases in which the second stage was longer than 180 min (33 vs 8 cases, P = 0.02). No differences in maternal postoperative complication rates and neonatal outcomes were observed. CONCLUSION: Fetal extraction via the 'legs first' method during prolonged second stage of labor may lower maternal morbidity. Method of delivery does not seem to have an effect on neonatal outcomes.

Experience and confidence in vaginal breech and twin deliveries among obstetric trainees and new specialists in Australia and New Zealand.

BACKGROUND: The number of vaginal breech and twin deliveries may be insufficient for adequate training. OBJECTIVE: To determine whether advanced trainees and new Fellows in obstetrics are gaining adequate experience and confidence in vaginal breech and twin deliveries. METHODS: An online survey was emailed to registered Royal Australia and New Zealand College of Obstetrics and Gynaecology (RANZCOG) advanced trainees and new Fellows (Years 1-5). This survey asked about their experience, confidence and whether they intend to perform vaginal breech and twin deliveries as specialists. RESULTS: The survey was sent to 703 advanced trainees (162) and Fellows (541) and answered by 217 (31.7%). Experience and confidence in vaginal breech and twin deliveries increased with the number of procedures performed (P < 0.001) in both groups and were significantly higher among Fellows. Despite the level of experience, 100% of respondents felt confident in managing vaginal twin deliveries with or without supervision, whereas 14.9% of respondents did not feel confident in managing vaginal breech deliveries. Intention to offer these procedures in their practice depended on confidence levels, and there was a significant difference between twins and breech. Overall, 87.3% of respondents intended to offer vaginal twin deliveries in their practice, while only 32.7% intended to offer vaginal breech deliveries. CONCLUSION: Confidence in complex vaginal deliveries increases with increasing number of procedures performed and a significant proportion of trainees and Fellows consider they do not have sufficient experience. The association between confidence and intention to offer these procedures is stronger in twins than in breech deliveries.

Successful preterm pregnancy in a rare variation of Herlyn-Werner-Wunderlich syndrome: a case report.

BACKGROUND: Herlyn-Werner-Wunderlich syndrome (HWWS) is an uncommon congenital anomaly of the female urogenital tract, characterised by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. We reported the difficult pregnancy course complicated by an extremely rare and unique case of this syndrome associated with ectrodactyly, a clinical combination never described in literature. CASE PRESENTATION: A 28- year-old nulliparous woman previously diagnosed for HWWS associated with ectrodactyly of the right foot and with a history of abdominal left hemi-hysterectomy, ipsilateral salpingectomy, vaginal reconstruction when she was an adolescent. She suffered from threats of abortion in the first trimester, recurrent urinary tract infections during all pregnancy. At 33 weeks + 5 days of gestational age, she was hospitalized for premature rupture of the membranes and uterine contractions and a caesarean section was performed because of breech presentation. Postpartum period was complicated by a pelvic abscess resolved with parental antibiotic therapies. CONCLUSIONS: Our literature review shows an unusual aspect in our case: HWWS is not classically associated with skeletal anomalies. Moreover, the most frequent urogenital side affected is the right, not left side as in this woman. Preterm spontaneous rupture of membranes and fetal abnormal presentation represent frequent complications and probably post-caesarean infections are related to pregnancies in the context of this syndrome.

Uptake of external cephalic version for term breech presentation: an Australian population study, 2002-2012.

BACKGROUND: The safety, efficacy, and cost-effectiveness of external cephalic version (ECV) for term breech presentation has been demonstrated. Clinical guidelines recommend ECV for all eligible women, but the uptake of this procedure in the Australian healthcare setting is unknown. This study aimed to describe ECV uptake in New South Wales, the most populous state of Australia, during 2002 to 2012. METHODS: Data from routine hospital and birth records were used to identify ECVs conducted at ≥36 weeks' gestation. Women with ECV were compared to women who were potentially eligible for but did not have ECV. Eligibility for ECV was based on clinical guidelines. For those with ECV, birth outcomes following successful and unsuccessful procedures were examined. RESULTS: In N = 32,321 singleton breech pregnancies, 10.5% had ECV, 22.3% were ineligible, and 67.2% were potentially eligible but did not undergo ECV. Compared to women who were eligible but who did not attempt ECV, those who had ECV were more likely to be older, multiparous, overseas-born, public patients at delivery, and to deliver in tertiary hospitals in urban areas (p < 0.01). Fewer women who underwent ECV smoked during pregnancy, fewer were morbidly obese, and fewer had a hypertensive disorder of pregnancy, compared to those who were eligible. Caesarean section occurred in 25.9% of successful compared to 95.6% of unsuccessful ECVs. Infant outcomes did not differ by ECV success. CONCLUSIONS: The majority of women with a breech presentation did not receive ECV. It is unclear whether this is attributable to issues with service provision or low acceptability among women. Policies to improve access to and information about ECV appear necessary to improve uptake among women with term breech presentation. Improved data collection around the diagnosis of breech presentation, ECV attempts, and outcomes may help to identify specific barriers to ECV uptake.

Reporting Caesarean Delivery in Quebec Using the Robson Classification System.

OBJECTIVE: The increasing rates of Caesarean sections throughout the world is preoccupant, and a good understanding of which groups of women contribute the most to the CS rate represents an important question in public health. Therefore, we sought to report the CS rate according to the Robson's classification system in the Quebec population. METHOD: We performed a secondary analysis of the QUARISMA database, including all deliveries after 24 weeks' gestation from 32 maternity wards in the province of Quebec between 2008 and 2011 (n = 184 952 deliveries). CS rates were reported according to the modified Robson criteria from The Society of Obstetricians and Gynaecologists of Canada with the relative contribution to the total number of CSs. RESULTS: We observed a global CS rate of 22.9%. Women with previous CS and a fetus in cephalic presentation at term accounted for 35% of all Caesarean deliveries. Nulliparous women with cephalic presentation at term accounted for 30% of all CSs. Among nulliparous women with cephalic presentation, women with spontaneous labour contributed to 12% of all CSs, whereas women with an induction of labour contributed to 16% of all CSs. Non-cephalic fetal presentation accounted for 19% of all CSs. Other indications accounted for the remaining 16% of CSs. CONCLUSION: Most CSs are performed for multiparous women with previous CS; nulliparous women with a cephalic presentation at term, especially those undergoing labour induction; and non-cephalic fetal presentation.

Risk factors and outcomes in "well-selected" vaginal breech deliveries: a retrospective observational study.

OBJECTIVE: To assess risk factors for adverse perinatal and neonatal outcomes in "well-selected" singleton vaginal breech deliveries at term. METHODS: During the time span from January 2008 up to April 2015 a total of 786 singleton term breech deliveries with a planned vaginal delivery were identified in a retrospective observational study at Helsinki University Central Hospital, Finland. The study's end point was a composite of adverse perinatal and neonatal outcomes. Infants with an adverse outcome were compared to all spontaneous singleton vaginal breech deliveries with normal perinatal and neonatal outcomes. A multivariate logistic regression model was used to analyze associations between adverse neonatal outcomes and several variables. The secondary outcome was the severe morbidity rate according to the criteria of the term breech trial. RESULTS: An adverse neonatal outcome was recorded for 38 (4.8%) infants. According to the study the second delivery stage lasting <40 min [adjusted odds ratio (aOR): 0.34, 95% confidence interval (95% CI): 0.15-0.79] was associated with lower odds and had a protective effect against adverse outcomes. Epidural anesthesia (aOR: 2.88, 95% CI: 1.08-7.70) was associated with higher adverse outcomes. The incidence rate of severe morbidity was 1.3% (10/787). CONCLUSION: Adverse neonatal outcomes in well-selected breech deliveries are associated with a prolonged second delivery stage lasting >40 min and with epidural anesthesia.
