Background: External cephalic version is a procedure used to turn a fetus from a breech position to a cephalic position before delivery. The success rate of the external cephalic version can be affected by various factors; however, the effect of bladder volume on the success rate of the external cephalic version remains controversial., Objective: This study aimed to determine the effect of urinary bladder status (full or empty) on the success rate of the external cephalic version through a prospective randomized study., Study Design: This was a prospective randomized controlled trial conducted at a tertiary care obstetrical center. Overall, 70 women with a singleton breech presentation at term undergoing external cephalic version were randomly allocated into 2 groups: external cephalic version with an empty bladder and external cephalic version with a full bladder. The external cephalic version procedure was performed by experienced obstetricians under ultrasound guidance. The primary outcome was the success rate of the external cephalic version., Results: The success rate of the external cephalic version was 67.56% (25/37) in the full bladder group and 54.54% (18/33) in the empty bladder group, with no statistically significant difference between the groups (P=.26). In addition, the relative risk of successful external cephalic version was 1.23 (95% confidence interval, 0.84-1.81), indicating no significant difference., Conclusion: This randomized controlled trial demonstrated that the presence of a full or empty urinary bladder does not significantly affect the success rate of the external cephalic version in women with singleton breech presentation at term. Our findings suggest that women undergoing an external cephalic version do not need to have a full bladder to improve the success rate of the procedure., (Copyright © 2023 Elsevier Inc.

Background: Breech presentation at term contributes significantly to cesarean section (CS) rates worldwide. External cephalic version (ECV) is a safe procedure that reduces term breech presentation and associated CS. A principal barrier to ECV is failure to diagnose breech presentation. Failure to diagnose breech presentation also leads to emergency CS or unplanned vaginal breech birth. Recent evidence suggests that undiagnosed breech might be eliminated using a third trimester scan. Our aim was to evaluate the impact of introducing a routine 36-week scan on the incidence of breech presentation and of undiagnosed breech presentation., Methods and Findings: We carried out a population-based cohort study of pregnant women in a single unit covering Oxfordshire, United Kingdom. All women delivering between 37+0 and 42+6 weeks gestational age, with a singleton, nonanomalous fetus over a 4-year period (01 October 2014 to 30 September 2018) were included. The mean maternal age was 31 years, mean BMI 26, 44% were nulliparous, and 21% were of non-white ethnicity. Comparisons between the 2 years before and after introduction of routine 36-week scan were made for 2 primary outcomes of (1) the incidence of breech presentation and (2) undiagnosed breech presentation. Secondary outcomes related to ECV, mode of birth, and perinatal outcomes. Relative risks (RRs) with 95% confidence intervals (CIs) are reported. A total of 27,825 pregnancies were analysed (14,444 before and 13,381 after). A scan after 35+0 weeks was performed in 5,578 (38.6%) before, and 13,251 (99.0%) after (p < 0.001). The incidence of breech presentation at birth did not change significantly (2.6% and 2.7%) (RR 1.02; 95% CI 0.89, 1.18; p = 0.76). The rate of undiagnosed breech before labour reduced, from 22.3% to 4.7% (RR 0.21; 95% CI 0.12, 0.36; p < 0.001). Vaginal breech birth rates fell from 10.3% to 5.3% (RR 0.51; 95% CI 0.30, 0.87; p = 0.01); nonsignificant increases in elective CS rates and decreases in emergency CS rates for breech babies were seen. Neonatal outcomes were not significantly altered. Study limitations include insufficient numbers to detect serious adverse outcomes, that we cannot exclude secular changes over time which may have influenced our results, and that these findings are most applicable where a comprehensive ECV service exists., Conclusions: In this study, a universal 36-week scan policy was associated with a reduction in the incidence but not elimination of undiagnosed term breech presentation. There was no reduction in the incidence of breech presentation at birth, despite a comprehensive ECV service., Competing Interests: The authors have declared that no competing interests exist.

Background: External cephalic version (ECV) is a frequently performed obstetric procedure for fetal breech presentation to avoid cesarean delivery. Neuraxial, intravenous, and inhalational anesthetic techniques have been studied to reduce maternal discomfort caused by the forceful manipulation. This study compares the effects of these anesthetic techniques on ECV and incidence of cesarean delivery., Methods: We conducted a comprehensive literature search for published randomized controlled trials (RCTs) or well-conducted quasi-randomized trials of ECV performed either without anesthesia or under neuraxial, intravenous, or inhalational anesthesia. Pairwise random-effects meta-analyses and network meta-analyses were performed to compare and rank the perinatal outcomes of the 3 anesthetic interventions and no anesthesia control, including the rate of successful version, cesarean delivery, maternal hypotension, nonreassuring fetal response, and adequacy of maternal pain control/satisfaction., Results: Eighteen RCTs and 1 quasi-randomized trial involving a total of 2296 term parturients with a noncephalic presenting singleton fetus were included. ECV under neuraxial anesthesia had significantly higher odds of successful fetal version compared to control (odds ratio [OR] = 2.59; 95% confidence interval [CI], 1.88-3.57), compared to intravenous anesthesia (OR = 2.08; 95% CI, 1.36-3.16), and compared to inhalational anesthesia (OR = 2.30; 95% CI, 1.33-4.00). No association was found between anesthesia interventions and rate of cesarean delivery. Neuraxial anesthesia was associated with higher odds of maternal hypotension (OR = 9.33; 95% CI, 3.14-27.68). Intravenous anesthesia was associated with significantly lower odds of nonreassuring fetal response compared to control (OR = 0.36; 95% CI, 0.16-0.82). Patients received neuraxial anesthesia reported significantly lower visual analog scale (VAS) of procedure-related pain (standardized mean difference [SMD] = -1.61; 95% CI, -1.92 to -1.31). The VAS scores of pain were also significantly lower with intravenous (SMD = -1.61; 95% CI, -1.92 to -1.31) and inhalational (SMD = -1.19; 95% CI, -1.58 to -0.8) anesthesia. The VAS of patient satisfaction was significantly higher with intravenous anesthesia (SMD = 1.53; 95% CI, 0.64-2.43)., Conclusions: Compared to control, ECV with neuraxial anesthesia had a significantly higher successful rate; however, the odds of maternal hypotension increased significantly. All anesthesia interventions provided significant reduction of procedure-related pain. Intravenous anesthesia had significantly higher score in patient satisfaction and lower odds of nonreassuring fetal response. No evidence indicated that anesthesia interventions were associated with significant decrease in the incidence of cesarean delivery compared to control.

We report a case of idiopathic spontaneous intraperitoneal haemorrhage (ISIH) in a 31-year-old patient at 37 weeks gestation in her second pregnancy. The patient presented to the labour ward with abdominal pain and uterine contractions. The initial complain was of sudden onset, severe sharp pain in left iliac fossa. She started having uterine contractions within 30 min of her presentation. Examination confirmed early labour with a footling breech presentation. Urgent caesarean section was performed that confirmed peritoneal bleeding of unknown origin with safe delivery of the baby. Mother and baby were safely discharged on day 5. 'Abdominal apoplexy' (ISIH), is a rare obstetric emergency with increased risk of fetal and maternal morbidity and mortality. With various clinical presentations as a possibility, diagnosis is challenging. High index of suspicion with prompt management of suspected cases can be pivotal life saving measure for the fetus and mother., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

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 STATEMENT What 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.

Introduction: Vaginal delivery out of a breech presentation in pregnancies at term are being re-implemented into clinical practice. Still, recommendations regarding exclusion criteria leading to caesarean sections are based on expert opinions, not on evidence-based guidelines. The difference in perinatal outcome and course of delivery in births with babies in frank breech position and babies in incomplete or complete breech presentation never has been investigated in a large patient cohort., Objective: To compare perinatal outcome of vaginally intended breech deliveries between births out of frank breech position and incomplete/complete breech presentation., Design: Prospective cohort study., Sample: 884 women at term with a singleton in frank breech presentation (FB) and 284 women with incomplete or complete breech presentation (CB) intending vaginal birth between January 2004 and December 2018., Methods: Maternal and fetal outcome was compared between groups using Pearson's Chi Square test. Birth duration parameters were analysed using logistic regression., Results: There were no differences in cesarean section rates (FB: 25.1%, CB 22.2%, p = 0.317). Short-term fetal morbidity did not differ between groups (FB: 2.5%, CB: 2.8%, p = 0.761). In vaginal deliveries the necessity to perform manual assistance was significantly more frequent in deliveries of infants in CB (FB: 39.9%, CB: 51.6%, p = 0.0013). Cord loops (FB: 10.1%, CB: 18.0%, p = 0.0004) and cesarean sections necessary because of cord prolapses (FB: 1.4%, CB 8.1%, p = 0.005) were significantly more often in deliveries with babies in CB., Conclusion: This study provides evidence, that perinatal morbidity is not associated with the fetal leg posture in vaginally intended breech deliveries. The higher risk for the need of manual assistance during vaginal birth in deliveries of babies out of complete or incomplete breech presentation suggests that obstetrical departments re-implementing the vaginal breech in their repertoire might start with births of babies out of frank breech presentation., Competing Interests: The authors have declared that no competing interests exist.

Objective: To explore factors that influence parents' decision-making for mode of breech birth at term gestation., Design: A grounded theory study conducted using a constructivist approach. Semi-structured telephone interviews were recorded and transcribed verbatim and analysed using the software NVivo for Mac version 11.4.0., Setting: England, UK., Participants: Twelve parents with breech presentation confirmed by ultrasound at ≥36+0 weeks gestation were recruited from several UK social media forums., Findings: Two core themes impacting on a parent's decision-making process for term breech birth were identified. Firstly, a framework of potential influences including partner and relationship, family and friends, health professionals, own birth culture, self, shared experiences and the time available for decision-making. Secondly, mortality salience, or parental focus on risk of potential injury or death associated with birth, was found to be central to every participant's narrative., Key Conclusions: This study highlights the individuality and wider framework of parent's decision-making influences for term breech birth, and demonstrates to care providers the conflicted emotions that may be experienced. The findings of this study may guide midwives and other professionals in providing person-centered, non-judgmental, balanced and evidence-based mode of term breech birth counselling., Implications for Practice: Health professionals should adopt a parentcentred approach to counselling for mode of term breech birth, considering parents' wider influences in their decision-making and the fear of injury or death surrounding both vaginal breech birth and caesarean section. They can also facilitate parents to understand the influences that might be guiding their own decision-making., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Background We aimed to analyze the success rate of external cephalic version (ECV) for breech presentations performed in our center between March 2011 and March 2016. We evaluated factors related to a successful ECV, delivery mode, complications and newborn status after ECV. Methods Analysis of assembled data of 327 consecutive ECVs in the third trimester was done. Results The total success rate was 56.6%. After a successful ECV, 85.9% of the fetuses were delivered vaginally. Logistic regression analysis of background factors leading to a successful ECV showed that tocolysis with ritodrine and anterior placenta were each significantly correlated with the rate of successful version. No severe complications were registered during the ECVs, and all babies had normal Apgar scores at delivery. Conclusion These findings suggest that attempting an ECV in breech presentations, once or even twice, seems to be an appropriate management given that a successful ECV decreases the rate of cesarean section in this group of patients and by doing so, it might also decrease the risk of cesarean sections in future pregnancies.

A precipitous delivery can be among the most stressful events an emergency physician encounters. The physician must assess 2 patients (mother and fetus) and be prepared to manage a variety of complications that may arise during delivery. A majority of precipitous deliveries result in good outcomes for both mother and baby, but emergency physicians must be prepared to manage feared complications, such as tight nuchal cords, shoulder dystocia, and breech presentation. An understanding of the labor process as well as advanced planning can help decrease the stress and chaos inherent to any precipitous delivery., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Despite the relative ease with which breech presentation can be identified through ultrasound screening, the assessment of foetal presentation at term is often based on clinical examination only. Due to limitations in this approach, many women present in labour with an undiagnosed breech presentation, with increased risk of foetal morbidity and mortality. This study sought to determine the cost effectiveness of universal ultrasound scanning for breech presentation near term (36 weeks of gestational age [wkGA]) in nulliparous women., Methods and Findings: The Pregnancy Outcome Prediction (POP) study was a prospective cohort study between January 14, 2008 and July 31, 2012, including 3,879 nulliparous women who attended for a research screening ultrasound examination at 36 wkGA. Foetal presentation was assessed and compared for the groups with and without a clinically indicated ultrasound. Where breech presentation was detected, an external cephalic version (ECV) was routinely offered. If the ECV was unsuccessful or not performed, the women were offered either planned cesarean section at 39 weeks or attempted vaginal breech delivery. To compare the likelihood of different mode of deliveries and associated long-term health outcomes for universal ultrasound to current practice, a probabilistic economic simulation model was constructed. Parameter values were obtained from the POP study, and costs were mainly obtained from the English National Health Service (NHS). One hundred seventy-nine out of 3,879 women (4.6%) were diagnosed with breech presentation at 36 weeks. For most women (96), there had been no prior suspicion of noncephalic presentation. ECV was attempted for 84 (46.9%) women and was successful in 12 (success rate: 14.3%). Overall, 19 of the 179 women delivered vaginally (10.6%), 110 delivered by elective cesarean section (ELCS) (61.5%) and 50 delivered by emergency cesarean section (EMCS) (27.9%). There were no women with undiagnosed breech presentation in labour in the entire cohort. On average, 40 scans were needed per detection of a previously undiagnosed breech presentation. The economic analysis indicated that, compared to current practice, universal late-pregnancy ultrasound would identify around 14,826 otherwise undiagnosed breech presentations across England annually. It would also reduce EMCS and vaginal breech deliveries by 0.7 and 1.0 percentage points, respectively: around 4,196 and 6,061 deliveries across England annually. Universal ultrasound would also prevent 7.89 neonatal mortalities annually. The strategy would be cost effective if foetal presentation could be assessed for £19.80 or less per woman. Limitations to this study included that foetal presentation was revealed to all women and that the health economic analysis may be altered by parity., Conclusions: According to our estimates, universal late pregnancy ultrasound in nulliparous women (1) would virtually eliminate undiagnosed breech presentation, (2) would be expected to reduce foetal mortality in breech presentation, and (3) would be cost effective if foetal presentation could be assessed for less than £19.80 per woman., Competing Interests: I have read the journal's policy and the authors of this manuscript have the following competing interests: GS reports grants from the National Institute for Health Research (NIHR), Stillbirth and Neonatal Death Society, and MRC and reports other from GE and NIHR Cambridge Clinical Research Facility, during the study; reports personal fees and other from GlaxoSmithKline and Roche, and reports other from Chiesi, outside of the study.

Background: The safety of vaginal breech birth depends on the expertise of birth attendants, yet the meaning of "expertise" remains unclear and subjectively defined. The objective of this study was to define expertise and the roles experts may play in expanding access to this service., Methods: We performed an integrative analysis of two strands of data concerning expertise in physiological breech birth, including the following: survey data from a Delphi study involving 26 very experienced clinicians (mean experience = 135 breech births) and 2 service user representatives, and interviews from a grounded theory study of 14 clinicians more moderately experienced with physiological methods (5-30 upright breech births). Data were pooled and analyzed using constant comparative methods., Results: Expertise is defined by its ongoing function, the generation of comparatively good outcomes, and confidence and competence among colleagues. Although clinical experience is important, expertise is developed and expressed in social clinical roles, which expand as experience grows: clinician, mentor, specialist, and expert. To develop expertise within a service, clinicians who have an interest in breech birth should be supported to perform these roles within specialist teams., Conclusions: Specialist breech teams may facilitate the development of expertise within maternity care settings. Evaluation of expertise based on enablement of women and colleagues, as well as outcomes, will potentially avoid the pitfalls of alienation produced by some forms of specialist authority., (© 2017 Wiley Periodicals, Inc.)

Huge ovarian cyst are found in less than 1% of all ovarian cyst in pregnancy and are associated with poor feto-maternal outcome. A 28 years old G2P1 with history of normal vaginal delivery 3 years back was referred from local health post with complains of intermittent pain abdomen at 29 weeks. Her scan showed huge ovarian cyst of 18.9×17.6 cm with multiple thick septation. Woman was conservatively managed till term and elective surgery was planned however she presented in labour with breech presentation at 39 weeks and 4days. Emergency lower segment caesarian section along with left sided salpingo-oophorectomy was done along with delivery of 2.5 kg healthy female baby. Histopathology was suggestive of mucinous cystadenoma of ovary. Although antepartum removal of ovarian cyst has been recommended to ensure good pregnancy outcome, expectant management and timed intervention can be adopted for pregnancy with huge ovarian cysts. Keywords: mucinous cystadenoma; ovarian cyst; pregnancy.

Introduction: This study was done to find out the incidence of malpresentation among all deliveries with various types of Malpresentations, its mode of delivery , maternal and fetal predisposing factors with outcome., Methods: This was a cross sectional descriptive study done at KIST Medical College and Teaching Hospital. Review cases of women admitted in labor after 22 weeks with malpresentation was done. Maternal/fetal predisposing factors were recorded., Results: Total delivery in study period was 4009 where 101 (2.5%) were of malpresentation. Breech was the commonest malpresentation 83 (82.1%). Assisted vaginal delivery occurred in 16 (15.8%) and 953 (84.2%) caesarian section. Malpresentations was common in primigravida 62 (61.3%). Half (47.2%) cases had one/more predisposing factors, commonest being oligohydramnious 7 (6.9%). Out of 108 babies with malpresentation, 10 had perinatal deaths and 10 had NICU admissions. Congenital anomaly was found in 4 babies., Conclusions: The most common type of malpresentation was breech common in primigravida with oligohydramnios as contributing factor.

Background: Breech presentation affects 3-4% of pregnancies at term and malpresentation is the primary indication for 10-15% of cesarean deliveries. External cephalic version is an effective intervention that can decrease the need for cesarean delivery; however, timely identification of breech presentation is required. We hypothesized that women with a fetus in a breech presentation that is diagnosed after 38 weeks' estimated gestational age have a decreased likelihood of external cephalic version attempted and an increased likelihood of cesarean delivery., Methods: This was a retrospective cohort study. A chart review was performed for 251 women with breech presentation at term presenting to our tertiary referral university hospital for external cephalic version, cesarean for breech presentation, or vaginal breech delivery., Results: Vaginal delivery was significantly more likely (31.1% vs 12.5%; P<.01) in women with breech presentation diagnosed before 38 weeks' estimated gestational age as external cephalic version was offered, and subsequently attempted in a greater proportion of women diagnosed before 38 weeks. External cephalic version was more successful when performed by physicians with greater procedural volume during the 3.5 year period of the study (59.1% for providers performing at least 10 procedures vs 31.3% if performing fewer than 10 procedures, P<.01)., Conclusions: Results support the need for interventions to increase timely diagnosis of breech presentation as well as improved patient counseling and use of experienced providers for external cephalic version., (© 2017 Wiley Periodicals, Inc.)

Data from the literature on induction of labour in breech presentation are rare and no conclusions can be drawn for this procedure., Objectives: To evaluate obstetrical and neonatal prognosis following induced labour in breech deliveries at term (37 to 42 weeks of gestation)., Methods: We conducted a single-centre retrospective case-control study in a level IIB maternity unit from 1st January 2012 to 31st December 2015. The inclusion criteria were a singleton pregnancy and a breech presentation., Results: A total of 235 patients were included, 178 in the spontaneous labour group (group A), 57 in the induced labour group (whatever the procedure used: oxytocin or prostaglandin) (group B). There was no significant difference concerning the vaginal delivery rate between group A and group B (88.2% versus 91.2%). Both groups were also similar for transfers to neonatal units (10.7% versus 15.8%), pH<7.0 (1.1% versus 1.8%) and 5-minute Apgar<4 (1.1% versus 1.7%). There were no neonatal deaths or transfers to neonatal intensive care units., Conclusion: Induced labour in breech presentation is feasible with a vaginal delivery rate similar to that in spontaneous labour and the same neonatal outcomes. This therapeutic option must be considered in trained obstetrical teams when vaginal delivery in breech presentations is not contraindicated., (Copyright © 2017 Elsevier Masson SAS.

Objective: To evaluate the effect of oral hydration on the success rate of external cephalic version (ECV)., Design: Randomized controlled and single-blind trial., Setting: Academic tertiary hospital with approximately 3,000 births annually., Participants: One hundred sixty-four women at a gestational age of at least 37 weeks with breech-presenting fetuses and normal amniotic fluid indexes (AFIs)., Methods: Participants were randomly assigned to drink 2000 ml or no more than 100 ml of water in the 2 hours before undergoing ECV. The AFIs were assessed before and after treatment by the same sonographer, who was blinded to the treatment group. Data were collected on relevant maternal and fetal characteristics and ECV success., Results: The mean AFI after hydration was significantly greater than that in the control group (15.5 cm vs. 13.4 cm, p = .003). The ECV success rate was 53.7% in the hydration group and 46.3% in the control group (odds ratio: 1.34, 95% confidence interval [0.69, 2.59]; p = .349). Hydration was well tolerated and there were no serious adverse events., Conclusion: Oral hydration significantly increased the AFIs but did not affect the success rate of ECVs., (Copyright © 2017 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Objective: To determine intrapartum and perinatal outcomes following successful external cephalic version for breech presentation at term., Study Design: This was a retrospective cohort study of outcomes following successful external cephalic version in 411 women at an Australian tertiary maternity unit between November 2008 and March 2015. The study cohort was compared with a control group of 1236 women with cephalic presentation who underwent spontaneous labor. Intrapartum intervention rates and adverse neonatal outcomes were compared between both groups., Results: The success rate of external cephalic version (ECV) was 66.4%. The spontaneous vaginal delivery rate in the study cohort was 59.4% (224/411) vs 72.8% (900/1236) in the control cohort (P<0.001). Intrapartum intervention rates (emergency cesarean section (CS) and instrumental delivery) were higher in the ECV group (38% vs 27.2%, P<0.001). Rates of emergency CS for non-reassuring fetal status (9.5%, 39/411 vs 4.4%, 54/1236, P⩽0.001) and failure to progress (13.4%, 55/411 vs 4.1%, 51/1236, P<0.001) were higher in the study cohort. Neonatal outcomes were worse in the study cohort-Apgar score <7 at 5 min (2.2%, 9/411 vs 0.6%, 8/1236, P<0.001) and abnormal cord gases (8.5%, 35/411 vs 0.2%, 3/1236, P<0.001). Rates for resuscitation at birth and admission to the neonatal intensive care unit were higher in the study cohort (6.1% vs 4.1% and 1.9% vs 1.1%, respectively) but these were not statistically significant., Conclusion: Labor following successful ECV is more likely to result in increased intrapartum intervention rates and poorer neonatal outcomes.

Introduction: Our objective was to compare the effect of two pain relief methods (remifentanil vs. nitrous oxide) on the success rate of external cephalic version., Material and Methods: We conducted a randomized open label parallel-group controlled single-center clinical trial with sequential design, at Cruces University Hospital, Spain. Singleton pregnancies in noncephalic presentation at term that were referred for external cephalic version were assigned according to a balanced (1:1) restricted randomization scheme to analgesic treatment with remifentanil or nitrous oxide during the procedure. The primary endpoint was external cephalic version success rate. Secondary endpoints were adverse event rate, degree of pain, cesarean rate and perinatal outcomes., Results: The trial was stopped early after the second interim analysis due to a very low likelihood of finding substantial differences in efficacy (futility). The external cephalic version success rate was the same in the two arms (31/60, 51.7%) with 120 women recruited, 60 in each arm. The mean pain score was significantly lower in the remifentanil group (3.2 ± 2.4 vs. 6.0 ± 2.3; p < 0.01). No differences were found in external cephalic version-related complications. There was a trend toward a higher frequency of adverse effects in the remifentanil group (18.3% vs. 6.7%, p = 0.10), with a significantly higher incidence rate (21.7 events/100 women vs. 6.7 events/100 women with nitrous oxide, p = 0.03). All reported adverse events were mild and reversible., Conclusions: Remifentanil for analgesia decreased external cephalic version-related pain but did not increase the success rate of external cephalic version at term and appeared to be associated with an increased frequency of mild adverse effects., (© 2016 Nordic Federation of Societies of Obstetrics and Gynecology.)

The authors note significant room for improvement in facilitating informed consent in the management of breech presentation. New Zealand maternity care providers, including midwives, general practitioners and specialist obstetricians, have legal duties to provide full and unbiased information about risks and benefits of all relevant treatment options. In the case of breech presentation, such options include the interventions of external cephalic version or planned caesarean section, as well as the option to decline intervention and proceed with a planned vaginal breech birth. Information should be presented in a balanced and accessible way and not limited to the provider's personal preferences. Women have legal rights to make an informed choice, to give or refuse consent, to a second opinion and to co-operation among providers. The right of competent persons to refuse medical treatment, including the right to refuse caesarean section, is well established. Clinical policies therefore should include appropriate and non-coercive care for women who choose to birth their breech-presenting baby vaginally, compliance with such policies should be the norm, and consideration should be given to any institutional reforms or educational priorities needed to achieve this.

Objective: Evaluation of fetal position is an important part of prenatal care. A woman with a breech presentation may need referral for external cephalic version, for assisted breech delivery, or to schedule a Caesarean section. In many centres, a breech presentation undetected until labour will result in an emergency Caesarean section, a less desirable alternative for both the mother and the health care system. The anecdotal reports of undiagnosed breech presentations at a busy maternity clinic prompted a study to quantify the missed breech presentations and to evaluate the effectiveness of the current detection process, with the aim of allowing no more than 1% of breech presentations to remain undetected until labour., Methods: We performed a retrospective analysis of 102 breech deliveries over a 14 month period to quantify missed breech presentations, and used a prospective physician survey documenting how fetal presentation was determined at 186 prenatal visits over four months to analyze the current detection process., Results: We found that approximately 8% of breech presentations were undetected until labour. We concluded that within the limitations of the small sample size evaluated, the current practice of using a vaginal examination to verify fetal presentation determined by abdominal palpation (Leopold's manoeuvres) may not be more accurate than abdominal palpation alone., Conclusion: The current detection process resulted in an unacceptably high rate of missed breech presentations. The results of this study prompted the clinic's acquisition of bedside ultrasound capability to assess fetal position.

Objective: External cephalic version (ECV) for breech presentation is not routinely performed by obstetricians in many clinical settings. The aim of this work is to assess to what extent the factors involved in performing ECV are relevant for the success and safety of ECV, in order to propose a practical check-list for assessing the feasibility of ECV., Methods: Review of 214 references. Factors involved in the success and risks of ECV (feasibility of ECV) were extracted and were scored in a semi-quantitative way according to textual information, type of publication, year of publication, number of cases. Simple conjoint analysis was used to describe the relevance found for each factor., Results: Parity has the pivotal role in ECV feasibility (relevance 16.6%), followed by tocolysis (10.8%), gestational age (10.6%), amniotic fluid volume (4.7%), breech variety (1.9%), and placenta location (1.7%). Other factors with estimated relevance around 0 (regional anesthesia, station, estimated fetal weight, fetal position, obesity/BMI, fetal birth weight, duration of manoeuvre/number of attempts) have some role in the feasibility of ECV. Yet other factors, with negative values of estimated relevance, have even less importance., Conclusions: From a logical interpretation of the relevance of each factor assessed, ECV should be proposed with utmost prudence if a stringent check-list is followed. Such a check-list should take into account: parity, tocolytic therapy, gestational age, amniotic fluid volume, breech variety, placenta location, regional anesthesia, breech engagement, fetal well-being, uterine relaxation, fetal size, fetal position, fetal head grasping capability and fetal turning capability.

Background: External cephalic version (ECV) reduces the chance of breech presentation at term birth and lowers the chance of a cesarean delivery. ECV services are now in place in many units in the United Kingdom but their effectiveness is unknown. The aim of this study was to investigate the reasons for breech presentation at term birth., Methods: We performed a retrospective cohort study of 394 consecutive babies who were in breech presentation at term birth in a large United Kingdom maternity unit that offers ECV. The cohort was analyzed over two time periods 10 years apart: 1998-1999 and 2008-2009., Results: Only 33.8 percent of women had undergone a (failed) ECV attempt. This low proportion was mainly because breech presentation was not diagnosed antenatally (27.9%). Other contributing factors were: ECV not offered by clinicians (12.2%), ECV declined by women (14%), and contraindications to ECV (10.7%). Over the 10-year period, the proportion of breech presentations that were not diagnosed antenatally increased from 23.2 to 32.5 percent (p = 0.04), which constituted 52.8 percent of women who had not undergone an ECV attempt in 2008-2009. Failure of clinicians to offer ECV reduced from 21.6 to 3.0 percent (p = 0.0001) and the proportion of women declining ECV decreased from 19.1 to 9.0 percent (p = 0.005). Overall, ECV attempts increased from 28.9 to 38.5 percent (p = 0.05)., Conclusions: Although ECV counseling, referral, and attempt rates have increased, failure to detect breech presentation antenatally is the principal barrier to successful ECV. Improved breech detection would have a greater impact than methods to increase ECV success rates., (© 2015 Wiley Periodicals, Inc.)

Objective: To determine the electrocardiographic performance and neonatal outcome of pregnancies with breech presentation and planned vaginal delivery monitored with ST-waveform analysis (STAN)., Design: Prospective observational study., Setting: University hospital, Norway; 2004-2008., Population: Singleton pregnancies with a gestational age above 35 + 6 weeks, breech presentation, selected for vaginal delivery and monitored with STAN., Methods: Common clinical guidelines for STAN monitoring were used. An experienced neonatologist graded the symptoms of neonatal encephalopathy. The outcome was compared with STAN-monitored high-risk deliveries in a vertex presentation (n = 5569) using logistic regression analysis., Main Outcome Measure: Frequency of ST events, indications of intervention for fetal distress, and neonatal morbidity and mortality., Results: Breech presentation occurred in 750 of 23,219 (3.2%) deliveries, 625 (83%) of which were selected for vaginal delivery. Intrapartum monitoring by STAN was performed in 433 (69%). Compared with vertex presentations, fetuses in breech presentation had a lower risk of baseline T/QRS rise during labour [odds ratio (OR) = 0.7, 95% confidence interval (95% CI) = 0.7-0.9, P = 0.003] and a higher risk for intervention as a result of preterminal cardiotocogram (OR = 2.9, 95% CI = 1.6-5.9, P = 0.001). The risks of perinatal mortality (OR = 1.8, 95% CI = 0.2-15, P = 0.6), cord metabolic acidosis (OR = 0.8, 95% CI = 0.2-3.2, P = 0.7) and moderate or severe neonatal encephalopathy (OR = 1.8, 95% CI = 0.5-6.2, P = 0.3) did not differ significantly between breech and vertex deliveries., Conclusion: STAN can be used for the surveillance of breech presentations selected for vaginal delivery with an acceptable neonatal outcome. The electrocardiogram (ECG) pattern during labour varies with the fetal presentation., (© 2014 Royal College of Obstetricians and Gynaecologists.)

Objective: Investigate the rate of internal podalic version followed by breech extraction for a second non-vertex twin with the first delivered vaginally, and compare neonatal outcome with emergency cesarean section., Design: Cohort study., Setting: National Danish Registers., Population: Twin pregnancies (1997-2012) with gestational age ≥34 weeks; first twin delivered vaginally, second by internal podalic version and breech extraction or cesarean section., Methods: Data were collected from the Danish National Patient Register and the Danish National Birth Register., Main Outcome Measures: Rates of delivery mode, 5-min Apgar score, asphyxia, umbilical cord pH, admission to neonatal intensive care unit, treatment by mechanical ventilation, and experience level of obstetricians performing internal podalic version., Results: 457 births were available for analysis: 39 cases of internal podalic version and breech extraction and 418 cesarean section cases for second twin. Compared with the cesarean section group, the internal podalic version group had lower rates of asphyxia. Apgar scores and umbilical cord pH levels were not significantly different, although with a tendency to be higher in the internal version than the cesarean section group, however, fewer cases needed mechanical ventilation. Thirty internal versions and breech extractions were performed by obstetricians with >5 years clinical experience and three by trainees., Conclusion: Cesarean sections for a second twin seem to have been frequent during the last 15 years while internal podalic version is a vanishing procedure. A slight tendency for better neonatal outcome was found in the internal podalic version and extraction group than cesarean section., (© 2014 Nordic Federation of Societies of Obstetrics and Gynecology.)

Femoral fractures due to birth trauma are an extremely rare but important birth injury. While vaginal breech delivery, although rare, can cause femur fracture, abdominal breech delivery is not expected to cause fracture. Here we report on a low birth weight infant who was delivered by cesarean section for breech presentation at 30 1/7 weeks of gestation and sustained a unilateral fracture of the femoral shaft.

This article discusses the background to undiagnosed breech and what a midwife can do to support a woman who is giving birth to a baby in an undiagnosed breech presentation. There is no evidence to support the use of emergency caesarean section when a breech is diagnosed in labour and it is a requirement of the Nursing and Midwifery Council rules and standards that registered midwives should have been taught, pre-registration, how to assist an undiagnosed breech presenting baby to be born.

Background: Clustering of outcomes at centers involved in multicenter trials is a type of center effect. The Consolidated Standards of Reporting Trials Statement recommends that multicenter randomized controlled trials (RCTs) should account for center effects in their analysis, however most do not. The Early External Cephalic Version (EECV) trials published in 2003 and 2011 stratified by center at randomization, but did not account for center in the analyses, and due to the nature of the intervention and number of centers, may have been prone to center effects. Using data from the EECV trials, we undertook an empirical study to compare various statistical approaches to account for center effect while estimating the impact of external cephalic version timing (early or delayed) on the outcomes of cesarean section, preterm birth, and non-cephalic presentation at the time of birth., Methods: The data from the EECV pilot trial and the EECV2 trial were merged into one dataset. Fisher's exact method was used to test the overall effect of external cephalic version timing unadjusted for center effects. Seven statistical models that accounted for center effects were applied to the data. The models included: i) the Mantel-Haenszel test, ii) logistic regression with fixed center effect and fixed treatment effect, iii) center-size weighted and iv) un-weighted logistic regression with fixed center effect and fixed treatment-by-center interaction, iv) logistic regression with random center effect and fixed treatment effect, v) logistic regression with random center effect and random treatment-by-center interaction, and vi) generalized estimating equations., Results: For each of the three outcomes of interest approaches to account for center effect did not alter the overall findings of the trial. The results were similar for the majority of the methods used to adjust for center, illustrating the robustness of the findings., Conclusions: Despite literature that suggests center effect can change the estimate of effect in multicenter trials, this empirical study does not show a difference in the outcomes of the EECV trials when accounting for center effect., Trial Registration: The EECV2 trial was registered on 30 July 30 2005 with Current Controlled Trials: ISRCTN 56498577.

Background: Objective was to determine whether fear for external cephalic version (ECV) and depression are associated with the success rate of ECV in women with a breech presentation at term., Methods: Prospective study conducted in the Catharina Hospital Eindhoven between October 2007 and May 2012. Participants fulfilled The Edinburgh Depression Scale (EDS) questionnaire and expressed their degree of fear on a visual analogue scale from one to ten before ECV. Obstetric factors were evaluated as well. Primary outcome was the relation between psychological factors (fear for ECV and depression EDS scores) and ECV success rate. Secondary outcome was a possible relation between fear for ECV and increased abdominal muscle tension., Results: The overall success rate was 55% and was significantly lower (p < 0.001) in nulliparous women (44.3%) compared with parous women (78.0%). Fear for ECV and depression EDS-scores were not related with ECV success rate. Parity, placental location, BMI and engagement of the fetal breech were obstetric factors associated with ECV outcome. There was no relation between fear for ECV and abdominal muscle tone., Conclusion: Fear for ECV and depression were not related with ECV success rate in this study. Engagement of the fetal breech was the most important factor associated with a successful ECV., Trial Registration Ebis: The Eindhoven Breech Intervention Study, NCT00516555.

Background: In this study, we sought to determine whether neuraxial anesthesia to facilitate external cephalic version (ECV) increased delivery costs for breech fetal presentation., Methods: Using a computer cost model, which considers possible outcomes and probability uncertainties at the same time, we estimated total expected delivery costs for breech presentation managed by a trial of ECV with and without neuraxial anesthesia., Results: From published studies, the average probability of successful ECV with neuraxial anesthesia was 60% (with individual studies ranging from 44% to 87%) compared with 38% (with individual studies ranging from 31% to 58%) without neuraxial anesthesia. The mean expected total delivery costs, including the cost of attempting/performing ECV with anesthesia, equaled $8931 (2.5th-97.5th percentile prediction interval $8541-$9252). The cost was $9207 (2.5th-97.5th percentile prediction interval $8896-$9419) if ECV was attempted/performed without anesthesia. The expected mean incremental difference between the total cost of delivery that includes ECV with anesthesia and ECV without anesthesia was $-276 (2.5th-97.5th percentile prediction interval $-720 to $112)., Conclusion: The total cost of delivery in women with breech presentation may be decreased (up to $720) or increased (up to $112) if ECV is attempted/performed with neuraxial anesthesia compared with ECV without neuraxial anesthesia. Increased ECV success with neuraxial anesthesia and the subsequent reduction in breech cesarean delivery rate offset the costs of providing anesthesia to facilitate ECV.

Any delivery in the emergency department is considered a precipitous birth and is an anxiety-producing event. Many deliveries proceed without incident. However, the emergency physician must be prepared for several dreaded scenarios, such as nuchal cord, shoulder dystocia, and breech birth. This article reviews the basics, complications, and management of such deliveries., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Background: At term, about 3-5% of the presentations are breech. Vaginal breech deliveries are associated with increased maternal and fetal morbidity and mortality, but delivery by cesarean section in an emergency does not eliminate all maternal and perinatal morbidity. The use of external cephalic version can produce considerable cost savings in the management of the breech fetus at term. The accuracy in the assessment of fetal presentation and position is essential., Objective: To study the accuracy of Leopold's maneuvers in the assessment of fetal presentation and position at Bhumibol Adulyadej Hospital., Material and Method: Prospective cohort study of 1,528 singletons, pregnant women at gestational age between 34-40 weeks who attended antenatal care unit at Bhumibol Adulyadej Hospital between November 1, 2006 and March 30, 2009. All cases were examined by either residents or staff by using Leopold's maneuvers. The results of the examinations were recorded as cephalic or non-cephalic presentation. After that, the subjects were re-examined by the staff in the maternal and fetal medicine unit using ultrasound for gold standard. Maternal age, weight, height, gestational age, parity, estimated fetal weight, amniotic fluid index, placental site, and fetal presentation were recorded. The results of the two methods of examination were then analyzed for comparison and calculated in terms of means, standard deviation, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy., Results: The results of Leopold's maneuvers with 95% confidence interval revealed sensitivity 63.17 +/- 10.84%, specificity 93.35 +/- 1.25%, positive predictive value 34.04 +/- 7.82%, negative predictive value 97.98 + 0.74%, and accuracy 92.08 +/- 1.35%., Conclusion: Leopold's maneuvers are inexpensive, easy to perform, and noninvasive but the accuracy of such assessments vary depending on many factors especially experience of operators. The caregivers can reduce perinatal morbidity and mortality if they can diagnose all of non-vertex presentation in near term pregnancy. Routine use of ultrasound in near term pregnancy to diagnose non-vertex presentation has more benefit than cost.

Objective: To evaluate new maneuvers developed by the author for fetal palpation in late pregnancy and comparing them with traditional Leopold's maneuvers., Methods: A total of 224 women with term pregnancy who underwent abdominal palpation by Sharma's modified Leopold's maneuvers developed by author using fingers, hands and forehand for better palpation were evaluated and compared with Leopold's Maneuver., Results: The mean age was 24.5 years, mean parity 2.2, mean gestation 38.2 weeks. Sharma's modified Leopold's pelvic maneuver could correctly diagnose occipito-anterior position in 95.0% cases as compared to 84.4% by Leopold's maneuvers (P=0.04), while it could correctly diagnose occipito-posterior position in 96.3% cases as compared to 66.6% by Leopold's maneuvers (P=0.0012). In breech presentation also Sharma's modified Leopold's fundal maneuver could correctly diagnose presentation in all cases as compared to 92.9% by Leopold's maneuvers. While in a transverse and oblique lie, Sharma's right and left lateral maneuvers could correctly diagnose presentation as well as position of acromion in all cases (100%)., Conclusion: The new maneuvers for fetal palpation appear to be very simple and accurate method for making out fetal presentation and position in late pregnancy.

Objective: To determine the success rate of External Cephalic Version (ECV) with 0.25 mg Salbutamol in singleton term breech and to identify the predictors of success., Study Design: Quasi experimental study., Place and Duration of Study: Mother and Child Health Centre, Pakistan Institute of Medical Sciences, Islamabad, from January 2000 to March 2005., Methodology: Women, presenting with uncomplicated breech, between 37-40 completed weeks gestation, underwent ECV in day care ward. Fifteen minutes before the procedure, injection salbutamol 0.25 mg was administered subcutaneously. Cases with contraindication to ECV or Salbutamol injection were excluded from the study. The outcome measures included success rate of ECV (in terms of conversion from breech to cephalic presentation at the completion of procedure confirmed through ultrasound), association of maternal and fetal demographic characteristics with successful version and adverse effects related to the procedure in terms of fetal bradycardia, ante-partum still birth, antepartum hemorrhage and preterm labour. Rate of reversion to breech and drug-related side effects were also recorded as secondary outcome measures. Chi-square test was used for categorical variables and independent sample t-test for continuous variables., Results: Of the 101 ECV procedures, 41 (40.5%) were successful. Success rate was significantly lower in nullipara (p=0.01) and with AFI 7 cm or less (p=0.04). No significant association was found between success rate and gestational age (p=0.35) or fetal birth weight (p=0.57). None of the patient suffered from serious maternal complications. Salbutamol related minor effects (tremors, anxiety and palpitations) were observed in 36 (35.6%) patients. Fetal tachycardia was seen in 17 (16.8%), reversible fetal bradycardia in 3 (2.9%) and intractable fetal bradycardia in one patient., Conclusion: External cephalic version with 0.25 mg Salbutamol was safe and a feasible option in term breech presentation in this series. Administration of tocolytic agent improved the success rate and reduced complication rate of the procedure. Major determinants of success were amniotic fluid index and parity.

Background: Most research on breech relates to medical management of the malpresentation. Little is known about women's or providers' experiences of breech, an obstetrical complication., Objectives: This study aims to increase the understanding of women's and providers' experiences of breech presentation and to understand the effects of context on these experiences., Methods: A qualitative descriptive research was conducted in a rural health district of Jamaica. Nine postpartum women who birthed singleton live born breech infants in the past year and five experienced obstetric care providers consented to participate. Content analysis was conducted with data from one-time interviews, observations, and hand searches of maternity ward delivery logs. Member checking was conducted with successive participants and Jamaican health care providers., Results: Findings included realizing the baby was breech, interpreting what breech meant, reacting to breech presentation, and identifying the impact of breech. Rates of breech births were less than 1%., Conclusions: Symbolic interaction can guide nursing and midwifery education, practice and research of breech presentation. Nurses and midwives can identify and teach women and their significant others about breech and its risks.

Background: Incarceration of the retroverted gravid uterus is an extremely rare diagnosis in the third trimester that carries significant maternal operative and postoperative morbidity., Case: The condition was diagnosed clinically in the third trimester of a primigravida. Despite the preoperative diagnosis, operative delivery proved difficult, requiring delivery of the fetus through the posterior wall of the uterus. Thirty-six hours after delivery the patient had a pulmonary embolus., Conclusion: This case report discusses the diagnosis and management of the condition incarcerated, retroverted uterus with postpartum pulmonary embolism. Prophylactic low molecular weight heparin in the antepartum period should be a considered for possible venous stasis due to the anatomy of the uterus.

The purpose of this article was to perform a critical analysis of publications having estimated the utility of X-ray pelvimetry, in order to allow tangible and useful conclusions for the clinical practice. X-ray pelvimetry was proposed in 3 indications: trial of labour among patients with a history of caesarean section, breech presentation, suspicion of cephalopelvic disproportion. The large majority of these publications are retrospective studies, studying a low number of patients and especially without control groups or randomisation. Their contradictory results and their methodological weaknesses do not allow any conclusion. Published randomised trials are exceptional. Among patients with a history of caesarean section, there is only one randomised trial; it demonstrates that ante-partum X-ray pelvimetry is not necessary prior to a trial labour in women with one previous caesarean section. It increases the caesarean section rate and is a poor predictor of the outcome of labour. There is also only one randomised trial which evaluated the interest of X-ray pelvimetry in patients with a breech presentation: the use of pelvimetry in breech presentation at term does not significantly reduce the overall caesarean-section rate, and does not improve the neonatal issues. However, it allows better selection of the delivery route, with a significantly lower emergency Caesarean-section rate. Finally, the only one randomised trial having studied the utility of X-ray pelvimetry for the prediction of cephalopelvic disproportion shows that pelvimetry is a poor predictor of the outcome of labour, has no influence on the neonatal issues and increases the caesarean sections rate. Furthermore, although radiation exposure during a X-ray pelvimetry is very weak, diagnostic X-ray studies during any stage of gestation have been shown to increase the risk of childhood cancer in the irradiated fetus. In the rare cases where pelvimetry is useful (trial of labour with a breech presentation), it is thus careful to perform a MRI pelvimetry.

Clinical audit is an effective quality improvement process to evaluate important clinical issues. Breech presentation is such an issue due to its contribution to the rising caesarean section (CS) rate. We set out to assess the management of breech presentation using, as standards, the delivery suite protocol and national guidelines. Our first audit revealed a low success rate of external cephalic version (ECV) and deficient documentation of written consent for ECV, other aspects of care being satisfactory. The results were presented to a multidisciplinary meeting and disseminated to relevant stakeholders. A re-audit was then performed. It confirmed significant improvement in the documentation of consent for ECV. It also revealed a good detection rate of breech, optimal offer rate of ECV and good neonatal outcome. However, uptake of ECV as well as the success rate could both be improved so as to reduce the CS rate for breech presentation. We discuss options for improving the uptake and success rate for ECV.
