Abstract
OBJECTIVE Uterine anomalies (UA) occur in up to 6.7% of women. Breech is eight times more likely to occur with UA which may not be diagnosed prior to pregnancy and may only be found in the third trimester with breech. The objective of the study is to assess the prevalence of both already known and newly sonographically diagnosed UA in breech from 36 weeks of gestation and its impact on external cephalic version (ECV), delivery options and perinatal outcomes. STUDY DESIGN We recruited 469 women with breech at 36 weeks of gestation over a 2-year period at the Charité University Hospital, Berlin. Ultrasound examination was performed to rule out UA. Patients with known and newly 'de novo' diagnosed anomalies were identified and delivery options and perinatal outcomes analyzed. RESULTS The 'de novo' diagnosis of UA at 36-37 weeks of pregnancy with breech was found to be significantly higher compared to the diagnosis prior to pregnancy with 4.5% vs 1.5% (p < 0.001 and odds ratio 4 with 95% confidence interval 2.12-7.69). Anomalies found included 53.6% bicornis unicollis, 39.3% subseptus, 3.6% unicornis and 3.6% didelphys. A trial of vaginal breech delivery was successful in 55.5% of cases when attempted. There were no successful ECVs. CONCLUSION Breech is a marker for uterine malformation. Diagnosis of UA with breech can be up to four times improved with focused ultrasound screening in pregnancy even from 36 weeks of gestation prior to ECV to identify missed anomalies. Timely diagnosis aids antenatal care and delivery planning. Importantly, definitive diagnosis and treatment can be planned postpartum to improve outcomes in future pregnancies. ECV plays a limited role in selected cases.

Abstract
AIM We aimed to investigate predictive factors of successful external cephalic version (ECV) using regional anesthesia. METHODS In this retrospective study, we included women who underwent ECV at our center from 2010 to 2022. The procedure had been conducted using regional anesthesia and the administration of intravenous ritodrine hydrochloride. The primary outcome was the success of ECV, which was defined as the rotation from a non-cephalic to a cephalic presentation. Primary exposures were maternal demographic factors and ultrasound findings at ECV. To determine predictive factors, we conducted a logistic regression analysis. RESULTS Of 622 pregnant women who underwent ECV, missing data on any variables (n = 14) were excluded and the remaining 608 were analyzed. The success rate during the study period was 76.3%. Multiparous women had significantly higher success rates than primiparous women (adjusted odds ratio [OR]: 2.06 [95% confidence interval (CI): 1.31-3.25]). Women with a maximum vertical pocket (MVP) of <4 cm had significantly lower success rates than those with 4 cm < MVP ≤6 cm (OR: 0.56 [95% CI: 0.37-0.86]). The non-anterior placental location was associated with higher success rates than the anterior placental location (OR: 1.46 [95% CI: 1.00-2.17]). CONCLUSIONS Multiparity, MVP >4 cm, and non-anterior placental locations were associated with successful ECV. These three factors could be useful for patient selection for successful ECV.

Abstract
Any non-cephalic presentation in a fetus is regarded as malpresentation. The most common malpresentation, breech, contributes to 3%-5% of term pregnancies and is a leading indication for cesarean delivery. Identification of risk factors and a proper physical examination are beneficial; however, ultrasound is the gold standard for the diagnosis of malpresentations. External cephalic version (ECV) refers to a procedure aimed to convert a non-cephalic presenting fetus to cephalic presentation. This procedure is performed manually through the mother’s abdomen by a trained health care provider, to reduce the likelihood of a cesarean section. Studies have reported a version success rate of above 50% by ECV. The main objective of this review is to present a broad perspective on fetal malpresentation, ECV, and delivery of a breech fetus. The focus is to elaborate all clinical scenarios of breech and to provide an evidence-based clinical approach for them. After discussing breech prevalence, risk factors, diagnosis, and management, an updated review of ECV is presented. Moreover, ECV indications/contraindications, alternatives, clinical techniques on how to perform ECV and breech vaginal delivery, and obstetrical considerations for the delivery of malpresentations are thoroughly discussed.

Abstract
Background and Objectives: In recent years, the rate of caesarean section (CS) has increased constantly. Although vaginal breech delivery has a long history, breech presentation has become the third most common indication for CS. This study aims to identify factors associated with the success of external cephalic version (ECV), underline the success rate of ECV for breech presentation and highlight the high rate of vaginal delivery after successful ECV. Material and Methods: This retrospective observational study included 113 patients with singleton fetuses in breech presentation, who underwent ECV from January 2016 to March 2021 in the Clinic of Obstetrics and Gynecology, Diakonieklinikum Schwäbisch Hall, Germany. Maternal and fetal parameters and data related to procedure and delivery were collected. Possible predictors of successful ECV were evaluated. Results: The success rate of ECV was 54.9%. The overall rate of vaginal birth was 44.2%, regardless of ECV outcome. The vaginal birth rate after successful ECV was 80.6%. Overall, 79.0% of women with successful ECV delivered spontaneously without complications, 19.4% delivered through CS performed during labor by medical necessity, and 1.6% delivered through vacuum extraction. ECV was performed successfully in three of the four women with history of CS. Gravidity, parity, maternal age, gestational age, fetal weight, and amniotic fluid index (AFI) were significantly correlated with the outcome of ECV. Conclusions: ECV for breech presentation is a safe procedure with a good success rate, thus increasing the proportion of vaginal births. Maternal and fetal parameters can be used to estimate the chances of successful ECV.

Abstract
To establish a clinical-based nomogram for predicting the success rate of external cephalic version (ECV) through a prospective study. This was a single-center prospective study that collected eligible breech pregnant women. 152 participants were enrolled in the training cohort, who received ECV procedures performed by a single operator. We used the training cohort to establish regression equations and prediction models. These variables include maternal factors (age, operation gestational age, pre-pregnancy BMI (Body Mass Index), operation BMI, BMI increase, multipara), ultrasound factors (fetal weight estimation, amniotic fluid index, placental location, type of breech presentation, spinal position), and anesthesia. Univariate and multivariable analyses were used to screen the factors affecting the success of ECV. A nomogram scoring model was established based on these factors. And C-index, DCA (Decision Curve Analysis) and calibration curve, Hosmer–Lemeshow test was used to verify the prediction effect of the model. Finally, 33 participants were enrolled in the testing cohort who received ECV with an unrestricted operator. We used C-index, DCA (decision curve analysis), and Hosmer–Lemeshow to verify the application value of the prediction model. The calibration curves and ROC curves of both the training cohort and testing cohort are plotted for internal and external validation of the model. The ECV success rate of the training cohort was 62.5%. Univariate analysis showed that the predictors related to the success rate of ECV were age, BMI increase value, AFI (amniotic fluid index), breech type, placental location, spinal position, anesthesia, and multipara. The prediction thresholds of the corresponding indexes were calculated according to the Youden index. Multivariate logistic regression analysis showed that BMI increase ≥ 3.85 kg/m2, AFI ≥ 10.6 cm, anesthesia, multipara, and non-anterior placenta were independent predictors of ECV success. Through the internal and external validation, it is confirmed that the model has a good calibration and prediction ability. Our nomogram has a good ability to predict the success rate of ECV.

Abstract
INTRODUCTION Treatment with beta-agonist tocolytics preceding external cephalic version (ECV) attempt increases success rates. Most studies have focused on intravenously and orally administered beta-agonists, while other administration routes including intramuscularly (IM) and subcutaneously (SC) are understudied. We aimed to compare the efficacy of IM ritodrine to SC salbutamol given prior to ECV. METHODS A retrospective study of patients who underwent ECV between 1/2012 and 12/2019 at two medical centers. We compared patients undergoing ECV following IM ritodrine versus SC salbutamol. We matched the two groups by parity and placental location. Maternal, pregnancy, ECV procedure and neonatal characteristics were compared. RESULTS Overall, 601 women were included in each group. Median maternal age and amniotic fluid index (AFI) were lower in the Ritodrine group (27 vs. 32 years, p<0.001, 11 vs. 15 AFI cm, p<0.001, respectively). The median gestational age at ECV was higher in the Ritodrine group (380/7 vs. 370/7 weeks gestation). Success rate was higher in the Ritodrine group (71.7% vs. 63.8%, p=0.003). Vaginal delivery rate was higher in the Ritodrine group (70.7% vs. 60.1%, p<0.001). The number needed to treat to benefit was 10. In a multivariate analysis, Ritodrine was independently associated with higher ECV success rates as compared with Salbutamol (aOR 2.1, 95%CI 1.52-2.89). CONCLUSIONS Intramuscular ritodrine significantly improved the success rate of ECV compared to SC salbutamol, and both drugs were safe and acceptable before ECV.

Abstract
PURPOSE External cephalic version (ECV) is an effective procedure to reduce the breech presentation at term reducing the chances of cesarean section. However even after successful ECV reports suggests the risk of having a cesarean section is high. The study analyzes the mode of delivery after a successful ECV and to identify the factors associated with intrapartum cesarean delivery compared to those with spontaneous cephalic presentation. METHODS This study was based on labor and delivery details, from the ECV registers, of 430 women who had successful ECV and they compared to those with spontaneous cephalic presentation. Primary outcome was delivery by cesarean section. Multiple logistic regression model was used to assess independent association of frisk factors associated with intrapartum cesarean section delivery by cesarean section and were presented as Odds Ratio (OR) and 95% confidence interval. RESULTS Cesarean section rates were similar among those who had a successful ECV and those with spontaneous cephalic presentation (22.3% vs 20.1%, p = 0.298). Women who had a successful ECV (OR = 1.5; (95%CI 1.13-1.98), maternal age (OR1.06-1.03-1.09), and previous delivery by cesarean section (OR = 5.16 (95%CI; 1.88-14.16) were found to associated with intrapartum cesarean section after adjusting for other factors. CONCLUSION Women who had a successful ECV had an increased risk of intrapartum cesarean section compared those women with spontaneous cephalic presentation. Further research should be performed to identify more risk factors, which could optimize intra-partum care to reduce the risk of cesarean section for women after successful ECV.

Abstract
OBJECTIVES To assess the feasibility of external cephalic version (ECV) for the leading twin (twin A) in breech presentation in dichorionic and diamniotic twin pregnancies without the use of regional anesthetics and tocolysis and to characterize the sonographic parameters, maternal and neonatal outcomes. STUDY DESIGN Prospective study performed in the Charité University Hospital outpatient obstetric department in Berlin, Germany. A total of 23 women from the 35th completed week of pregnancy with confirmed dichorionic-diamniotic twin pregnancy were recruited. ECVs were performed by the lead consultant for the breech and ECV clinic. Ethical approval provided by the Charité Ethics Commission (EA2/241/18). Demographic data were recorded. Fetal sonographic parameters were assessed. The success rate of ECV, duration of the ECV, gestational age at delivery, mode of delivery for both fetuses, maternal and neonatal outcomes were analyzed. RESULTS Our main finding showed that ECV for twin A breech in dichorionic-diamniotic twins is successful in 56% (10/18) of cases without the need for regional anesthesia and without tocolysis. There is a significant increase in the spontaneous vaginal delivery rate for both twins of 95% (19/20) vs 12.5% (2/16) (p < 0.001). There is also a significant reduction in blood loss at delivery of 300 ml vs 500 ml (p = 0.034) in successful cases. CONCLUSIONS We show that ECV for twin A in breech is feasible and in 56% (10/18) successful without regional anesthesia and tocolysis. The option of ECV for twin A breech should be offered to women.

Abstract
Introduction Cesarean section (CS) rates are increasing worldwide. One constant indication is the breech presentation at term. By offering external cephalic version (ECV) and vaginal breech delivery CS rates can be further reduced. Objective This study aimed to analyze the ECV at 38 weeks of gestation with the associate uptake rate, predicting factors, success rate, and complications at a tertiary healthcare provider in Germany specializing in vaginal breech delivery. Methods We conducted a prospective cohort study with retrospective data acquisition. All women with a singleton fetus in breech presentation presenting after 34 weeks of gestation for counseling between 2013 and 2017 were included. ECV impact factors were analyzed using logistic regression. Results A total of 1,598 women presented for breech birth planning. ECV was performed on 353 patients. The overall success rate was 22.4%. A later week of gestation (odds ratio [OR] 1.69), an abundant amniotic fluid index (AFI score) (OR 5.74), fundal (OR 3.78) and anterior (OR 0.39) placental location, and an oblique lie (OR 9.08) were significantly associated with successful ECV in our population. No major complications were observed. The overall vaginal delivery rates could be increased to approximately 14% with ECV. Conclusion The demand for alternative birth modes other than CS for breech birth is high in the area of Frankfurt, Germany. Our study offers evidence of the safety of ECV at 38 weeks. Centers with expertise in vaginal breech delivery and ECV can reduce CS-rates. To further establish vaginal breech delivery and ECV as alternate options, the required knowledge and skill should be implemented in the revised curricula.

Abstract
OBJECTIVES To present the consequences of and risk factors for abnormal bleeding after ECV (external cephalic version). METHODS We conducted a retrospective chart review at a single center in Japan. Abnormal bleeding was defined as vaginal bleeding and/or intrauterine hemorrhage. We descriptively assessed birth outcomes among women with abnormal bleeding, and investigated the risk factors using a logistic regression analysis. RESULTS Of 477 women who received ECV, 39 (8.2%) showed abnormal bleeding, including 16 (3.4%) with intrauterine hemorrhage. Of the 16 women with intrauterine hemorrhage, 14 required emergency cesarean section; none experienced placental abruption, a low Apgar score at 5 min (<7), or low umbilical cord artery pH (<7.1). Among 23 women who had vaginal bleeding without intrauterine hemorrhage, four cases underwent emergency cesarean section and one case of vaginal delivery involved placental abruption. The risk of abnormal bleeding was higher in women with a maximum vertical pocket (MVP) of <40 mm in comparison to those with an MVP of >50 mm (adjusted odds ratio [OR]: 3.48, 95% confidence interval [CI]: 1.23-9.90), as was higher in women with unsuccessful ECV than in those with successful ECV (aOR: 4.54, 95% CI: 1.95-10.6). CONCLUSIONS A certain number of women who underwent ECV had abnormal bleeding, including vaginal bleeding and/or intrauterine hemorrhage, many of them resulted in emergency cesarean section. Although all of cases with abnormal bleeding had good birth outcomes, one case of vaginal bleeding was accompanied by placental abruption. Small amniotic fluid volume and unsuccessful ECV are risk factors for abnormal bleeding.

Abstract
OBJECTIVES The objective of this study was to identify the factors predictive of the success of external cephalic version (ECV). METHODS A single-centre retrospective observational study was performed in the maternity ward of the Angers University Hospital, France, between January 2010 and May 2020. The study included all patients (n = 613) for whom an ECV was performed for a breech or transverse foetus. The primary endpoint was measured by the success of the ECV, defined by the visualisation, using pelvic ultrasound, of the foetus in cephalic presentation immediately after the manoeuvre. Following to the ECV, the cohort was separated into two groups; ECV Success and ECV Failure. In order to determine the predictive factors of success, a logistic regression model was performed, including the parameters of: parity, foetal presentation during ECV, the side of the foetal back, placental location, type of operator and maternal age. The results are presented as (odds ratio [confidence intervals]; p-value). The significance threshold was defined by a p-value < 0.05. RESULTS The ECV success rate was 21.4% (131/613). The factors predictive of the success of ECV were: transverse foetal presentation (2.7 [1.3-5.6]; p<0.01); a senior physician operator (1.6 [1.2-2]; p<0.01); multiparity (1.6 [1.2-2]; p<0.01); non anterior placental localization (1.4 [1.1-2]; p<0.01). A number of attempts greater than 3 were significantly associated with reduced chances of success (0.3 [0.2-0.4]; p<0.01). CONCLUSION The study shows that transverse foetal presentation, a senior physician operator, multiparity, as well as a non-anterior placental location are factors predictive of the success of ECV. Knowledge of these factors can improve the information given to patients.

Abstract
Objective: Breech presentation is the most common fetal malpresentation at term, with an incidence of 3-4%. External cephalic version (ECV) is a procedure that can be offered to women with breech presentation beyond 36 weeks of gestation to convert it to cephalic presentation, reducing the risks of a vaginal breech delivery and the morbidities associated with caesarean section. Material and Methods: We retrospectively reviewed the records of women who underwent ECV between October 2012 and June 2020 with the objectives of determining the success rate of the procedure, the mode of delivery, the maternal and neonatal outcomes, periprocedural complications and their management. Results: Among the 200 women who underwent the procedure with a 64% success rate (128 women), there were 110 vaginal deliveries (56.7%) including five vaginal breech deliveries, and 84 women (43.2%) underwent caesarean section, which included 24 women who had successful ECV but needed emergency caesarean for other indications. There was no significant difference in the neonatal APGAR scores in those who had a successful ECV and those who did not. Only three women (1.5%) experienced any significant periprocedural complication. Conclusion: These results suggest that ECV improves the possibility of a vaginal delivery with an overall low complication rate, reducing the neonatal risks associated with vaginal breech delivery and the maternal morbidity of a caesarean section. It may thus contribute to reducing the primary caesarean section rate, making it a useful intervention, especially in limited resource settings.

A Systematic Review and Meta-analysis of Clinical Trials of Neuraxial, Intravenous, and Inhalational Anesthesia for External Cephalic Version. Anesth Analg 2020; 131:1800-1811. [PMID: 32282385 PMCID: PMC7643798 DOI: 10.1213/ane.0000000000004795] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/02/2020] [Indexed: 01/22/2023]
Abstract
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.

Abstract
INTRODUCTION External cephalic version (ECV) for breech presentation involves manual manipulation of the fetus from breech to cephalic presentation at or near term, in an attempt to avoid breech birth. This systematic review summarizes the literature on the effects of ECV at or near term on pregnancy outcomes in high-resource settings. METHODS The MEDLINE, Embase, CINAHL, Cochrane Library, MIDIRS, and SweMED+ databases were searched for relevant articles published through April 2019, with no limitation on publication date. Clinical trials comparing the effects of ECV at ≥36 weeks, with or without tocolysis, with that of no ECV, conducted in northern, western, and central Europe, the USA, Canada, Australia, and New Zealand were eligible for inclusion. RESULTS Nine articles reporting on 184704 breech pregnancies were included. Pooled data showed that ECV attempts reduced the failure to achieve vaginal cephalic birth (risk ratio, RR=0.56; 95% CI: 0.45–0.71), caesarean section performance (RR=0.57; 95% CI: 0.50–0.64), and non-cephalic presentation at birth (RR=0.45; 95% CI: 0.29–0.68) compared with no ECV. ECV attempts also increased the incidence of Apgar score <7 at 5 minutes (RR=1.29; 95% CI: 1.10–1.52). CONCLUSIONS Women for whom ECV is attempted at or near term are at reduced risk of caesarean section, non-cephalic presentation at term, and failure to achieve vaginal cephalic birth. Compared with no ECV, attempted ECV was also associated with a slightly increased risk of a low Apgar score at 5 minutes. The evidence is limited by the scarcity of high-quality research and the presence of risks of bias.

Abstract
OBJECTIVE To evaluate the success rate of external cephalic version, predictive factors for success of this maneuver and to examine how it affects mode of delivery, pregnancy and neonatal outcome rates. STUDY DESIGN Retrospective cross-sectional study performed in a tertiary care university hospital between January 2002 and June 2018. A total of 324 ECVs were performed in 321 pregnancies. Maternal and ultrasound data, procedure-related factors, birth characteristics and neonatal data were collected. Absolute and relative frequencies were used for descriptive analysis and the chi-square test for comparative analysis. Odds ratios with 95 % confidence intervals were calculated. RESULTS The overall success rate of the procedure was 33,3%. Multiparity, transverse lie, unengaged breech presentation, low body mass index, soft uterus and palpable fetal head were independent risk factors for success. No statistically significant association was found with other variables. Routine use of ECV allowed a reduction in cesarean delivery rates for breech presentation, with no increase in maternal or neonatal morbidity. Operative delivery rates after successful ECV were similar to those of the general population. DISCUSSION AND CONCLUSION Despite a relatively low overall success rate, routine use of ECV can result in reduced cesarean delivery rates with similar perinatal outcomes. Conveyed information on the success rate of ECV can be adapted to individual patient characteristics.

Abstract
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).

Abstract
OBJECTIVES The aim of this study was to illuminate differences in guidelines for external cephalic version (ECV) for breech presentation at or near term and assess their impact on effectiveness of the procedure in order to improve policymaking. STUDY DESIGN Guidelines from all Swedish ECV providers (hospitals with labor wards, n = 44) were retrieved in 2019 and assessed for similarities and differences. The scoring system based on the identified differences in timing, contraindications and periprocedural care was created. The hospitals were subsequently classified into either restrictive or liberal with regard to ECV. This classification was verified by comparing selection of patients for ECV attempts between the two groups. Our main outcomes were ECV success rate and effectiveness in reducing the remaining breech births and breech cesarean sections. RESULTS Important differences in timing of ECV, contraindications, periprocedural care, and counselling after failed ECV attempt were found. Two thirds of the hospitals were considered liberal and one third restrictive with regard to ECV. ECV success rate was significantly higher in hospitals with a liberal attitude towards ECV compared with restrictive hospitals (54.0 % vs 50.5 %, p = 0.015). Liberal hospitals had a significantly lower proportion of remaining breech births (2.81 % vs 3.01 %, p = 0.009) and breech cesarean sections at or near term (2.49 % vs 2.72 %, p = 0.003). CONCLUSION Important differences in ECV guidelines were found. Hospitals with guidelines reflecting a liberal attitude to ECV had a higher ECV success rate, despite a less strict patient selection, and a lower proportion of breech births and breech cesarean sections, which is the aim of ECV. We recommend avoiding routine ill-founded restrictivity in ECV guidelines and support a more nuanced counselling.

Abstract
Introduction Fetal breech presentation at terms occurs in 3 - 6% of pregnancies. External cephalic version can reduce the number of cesarean sections and vaginal breech deliveries. Different approaches are used to carry out external cephalic version. This study looked at the different approaches used in Germany and compared the approach used with the recommendations given in German and international guidelines. Material and Methods An anonymized online survey of 234 hospitals in Germany was carried out in 2018. In addition to asking about hospital structures, questions also focused on how external version was carried out in practice (preparations, tocolysis, anesthetics, etc.), on relative and absolute contraindications and on the success rate. Results 37.2% of the hospitals approached for the survey participated in the study. Of these, 98.8% performed external version procedures. The majority of participating hospitals were university hospitals (26.4%) and maximum care hospitals (35.6%) with an average number of more than 2000 births per year (60.9%). External cephalic version is the preferred (61.7%) obstetrical procedure to deal with breech presentation, rather than vaginal breech birth or primary cesarean section. 45.8% of respondents carry out external version procedures on an outpatient basis, and 42.1% of hospitals perform the procedure as an inpatient intervention, especially from the 37th week of gestation. Prior to performing an external version procedure, 21.6% of surveyed institutions carry out a vaginal examination to evaluate possible fixation of the fetal rump. 95.5% of institutions used fenoterol for tocolytic therapy; the majority using it for continuous tocolysis (70.2%). 1 - 3 attempts at external version (8.4%) were usually carried out by a specific senior physician. In most cases, no analgesics were administered. The reported rate of emergency cesarean sections was very low. The most common indication for emergency C-section was pathological CTG (56,7%). The assessment of relative and absolute contraindications varied, depending on the surveyed hospital. 67.5% asked patients to empty their bladders before carrying out external version, while 10.8% carried out external version when the bladder was filled. The reported success rate was more than 45%. After successful version, only 14.8% of hospitals arranged for patients to wear an abdominal binder. For 32.4%, the decision to apply an abdominal binder was taken on a case-by-case basis. Conclusion The approach used in Germany to carry out external cephalic version is based on the (expired) German guideline on breech presentation. Based on the evidence obtained, a number of individual recommendations should be re-evaluated. More recent international guidelines could be useful to update the standard procedure.

Abstract
OBJECTIVE The management of breech presentation may improve perinatal outcomes. The aim of this study was to synthesize and compare published evidence of four national guidelines on breech presentation. STUDY DESIGN A descriptive review of four recently published national guidelines on breech presentation and external cephalic version (ECV) was conducted: Royal College of Obstetricians and Gynaecologists guideline on "External Cephalic Version and Reducing the Incidence of Term Breech Presentation" and "Management of Breech Presentation", American College of Obstetricians and Gynecologists guideline on "External Cephalic Version" and "Mode of Term Singleton Breech Delivery," Society of Obstetricians and Gynaecologists of Canada guideline on "Vaginal Delivery of Breech Presentation" and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists guideline on "Management of breech presentation at term." RESULTS Regarding ECV, there is no recommendation by the SOGC, whereas all other national guidelines recommend this technique. Regarding breech vaginal delivery, there are limited recommendations by the ACOG, whereas all other guidelines provide similar recommendations. The RANZCOG makes no special recommendations on the intrapartum period. CONCLUSION The differences among national guidelines point out the need for the adoption of an international consensus on the management of breech presentation.

Abstract
AIM External cephalic version (ECV) is an effective and safe technique for avoiding breech presentation at birth. However, it continues rejected by many women. The aim of this study is to develop a predictive model of success of external cephalic version, determine the safety of the technique and perinatal outcomes after successful version. METHODS Data from 317 versions performed over a 6-year period were collected. Different clinical and ultrasound variables, complications, vaginal delivery after successful version and perinatal outcomes were analyzed. RESULTS The overall success rate was 72% (229 of 317 versions). The variables most related to success were parity, placental location, amniotic fluid volume, fetal sex, fetal head palpation and descent of the presenting part. A model for calculating the probability of success was developed in which to input parity, placentation and amniotic fluid data. The model correctly classified 98.8% of successful technique and 74% of all women. Complications were very few and mostly mild. Of women who had success, 77% (163 of 212) had a vaginal birth. No differences between neonatal outcomes were found. CONCLUSION External cephalic version is a successful, safe technique with a high rate of subsequent vaginal delivery. A success prediction model based on some very easily obtained variables can personalize the probability of success.

Abstract
Objective Our aim was to assess the correlation of body mass index (BMI) with the success rate of external cephalic version (ECV) among women with one prior cesarean delivery. Study Design A cross-sectional study of pregnant women with one previous cesarean delivery who underwent ECV. The relationship between BMI and success rate of ECV was assessed. Adverse outcomes were also compared between women with an ECV attempt, and women who had a repeat cesarean delivery. Data were extracted from the U.S. Natality Database from 2014 to 2017. Pearson's correlation coefficient was performed to assess the relationship between BMI and success rate of ECV. Results There were 2,329 women with prior cesarean delivery underwent an ECV attempt. The success rate of ECV among the entire cohort was 68.3%. There was no correlation between BMI and success rate of ECV ( r = 0.024, p = 0.239). Risks of adverse maternal and neonatal outcomes were similar between the ECV attempt group and the repeat cesarean delivery group. Conclusion There was no correlation of BMI with the rate of successful ECV among women with one prior cesarean delivery. Given the similar success rates of ECV and adverse outcomes, obese women with one prior cesarean delivery should be offered ECV.

Abstract
INTRODUCTION In Catalonia caesarean rates have always been analysed as a single percentage. The objective is to estimate caesarean section rates using the Robson classification in publicly funded hospitals in Catalonia between 2013 and 2017, considering sociodemographic, institutional and obstetric characteristics. MATERIALS AND METHODS Cross-sectional population-based study in Catalonia including all women delivering within publicly funded hospitals between 2013-2017 (n = 210 020). The modified Robson classification distribution was estimated, the caesarean rate and the overall contribution, analysed for each year, and by confounders, through logistic regression models. RESULTS CS rates decreased steadily between 2013 and 2017 in Catalonia within publicly funded hospitals from 24.3% to 22.8% (cOR 0.92, 95% CI; 0.89 to 0.95). Once adjusted for changes in sociodemographic, institutional and obstetric characteristics the observed decline was even more pronounced (aOR 0.87, 95% CI; 0.84 to 0.90). Within the different groups of Robson once adjusted for confounders, groups 1+2 (aOR 0.88, 95% CI; 0.83 to 0.93), 3+4 (aOR 0.83, 95% CI; 0.78 to 0.89) and 10 (aOR 0.78, 95% CI; 0.68 to 0.90) presented a reduction in caesarean section rates, whereas group 5 showed no significant decrease (aOR 0.95, 95% CI; 0.87 to 1.03%). CONCLUSIONS The decrease in caesarean section rates in Catalonia is more pronounced when adjusted for known confounders, suggesting retrospective overutilization of caesarean section and percentages of (in)adequacy in the past. In any case, it remains above the recommended by experts. Further efforts should be made to achieve optimum rates, including improvement on obstetric data collection.

Abstract
Objective: Decreasing the primary cesarean delivery rate and associated maternal and fetal complications is a priority for obstetric care providers. External cephalic version (ECV) is a procedure recommended for women with singleton pregnancies where the fetus is malpresenting to avoid vaginal breech delivery, which is inherently riskier than cesarean delivery. However, little is known about this procedure in the context of twin gestations. Scheduled cesarean delivery is instead recommended for women with twin gestations where the presenting twin is not cephalic. Our aim is to evaluate the safety and efficacy of ECV in the setting of twin pregnancy where the presenting twin is not cephalic. We also present two patients with twin pregnancy at our institution that attempted ECV.Data sources: A systematic review of the following electronic databases was performed, searching from their inception until September 2019: Pubmed, Ovid, Scopus, and clinicaltrials.gov.Study eligibility criteria: All reported cases of ECV for a non-cephalic presenting twin were included. Studies were excluded if patients had contraindications to vaginal delivery and if they described ECV of the second twin only. Maternal demographics, procedure details, and outcomes data were collected.Study appraisal and synthesis methods: The primary outcome was a successful version of the presenting twin to the cephalic presentation following ECV. Statistical analysis involved calculating means, standard deviations, frequencies and percentages as appropriate.Results: Two case reports and one case series, totaling 22 patients, met inclusion criteria. Two additional patients attempted ECV at our institution. One completed ECV (for a total of 23 patients) while the other did not. This patient consented for ECV as Twin A was noted to be breeched upon presentation to labor and delivery but after receiving regional anesthesia, twin A was cephalic. No randomized controlled trials were identified. All were dichorionic pregnancies. Successful ECV of twin A occurred in 57% (13/23) of women and 48% (11/23) had a successful vaginal delivery. The majority were performed using regional anesthesia and a uterine relaxant (20/23). No serious adverse events occurred in any of the reports.Conclusions: ECV is insufficiently studied in twin pregnancy. Based on very limited data, it appears feasible to turn the non-cephalic presenting twin. Additional randomized controlled trials are needed to further evaluate the safety and efficacy of this procedure for a non-cephalic presenting twin.

Abstract
OBJECTIVE To design a clinically based predictive model for the likelihood of successful external cephalic version (ECV). METHODS This single-center retrospective study was conducted from February 2016 to July 2018 and included all candidates for ECV between 36 and 41 weeks of gestation. Variables with a potential effect on ECV success were collected. These variables include: body mass index, amniotic fluid index, gestational age, parity, location of placenta, fetal trunk posture, time in breech presentation before the procedure and the ultrasonographically measured size of the amniotic fluid preceding the fetal presenting part (fore-bag). Variables' association with ECV success was evaluated using a multivariate logistic regression and a decision tree predicting ECV outcome was developed using 75% of the patients and validated on the remaining 25%. RESULTS Overall, 250 pregnant women were identified and opted for a trial of ECV by a single operator, with a success rate of 64.8%. Body mass index, size of fore-bag, and parity were independent determinants of the version success, whereas other variables had no statistically significant effect on the success rate. Our decision tree model divided the cohort into five subgroups according to various combinations of the three variables. When evaluated on the internal validation set, the C-Index of the tree was 0.933 (0.863-1) and the prediction accuracy was 91.9% (86.5%-97.3%). CONCLUSION A prediction model composed of three easily measurable variables enables accurate prediction of successful ECV at term. Fore-bag was identified as the most important discriminator. Our model holds in internal validation and it can be used to support patient counseling and decision making for ECV but should be externally validated.

Abstract
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.

Abstract
OBJECTIVE External cephalic version (ECV) is a procedure during which the fetus is rotated from breech or transversal to cephalic presentation. Our aim was to assess the outcomes of successful ECV in terms of obstetrical and immediate neonatal outcomes relative spontaneous cephalic presentation. METHODS We performed a retrospective single-center observational study from January 2007 to December 2017. All included participants benefited from trial of labor with delivery of the fetus in cephalic presentation. They were divided into two groups depending on whether an ECV had been successfully performed or cephalic presentation was spontaneous. RESULTS The cephalic presentation after ECV and spontaneous cephalic groups comprised 55 and 244 patients, respectively. The two groups differed significantly in terms of the proportion of induced labor (20 [36.4 %] and 56 [22.9 %], p = 0.04), use of oxytocin during labor (31 [56.4 %] and 100 [49.9 %], p = 0.04), duration of labor (342 ± 183 min and 279 ± 140 min, p = 0.008), spontaneous delivery (38 [69.1 %] and 199 [81.5 %], p = 0.04), intrapartum cesarean section (9 [16.4 %] and 16 [6.6 %], p = 0.02), occiput-posterior variety at birth (20 [36.4 %] and 56 [22.9 %], p = 0.04), and brace umbilical positioning at birth (3 [5.4 %] and 2 [0.8 %], p = 0.04), respectively. There were no significant intergroup differences in terms of APGAR score, cord arterial pH/lactates, or reanimation/intensive care admission. CONCLUSION A successful ECV does not seem to guaranty an identical labor progress and obstetrical outcome as spontaneous cephalic presentations. Immediate neonatal state, on the other hand, seems unaffected by a history of ECV.

Understanding Factors Leading to Primary Cesarean Section and Vaginal Birth After Cesarean Delivery in the Friuli-Venezia Giulia Region (North-Eastern Italy), 2005-2015. Sci Rep 2020; 10:380. [PMID: 31941963 PMCID: PMC6962159 DOI: 10.1038/s41598-019-57037-y] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Accepted: 12/22/2019] [Indexed: 01/21/2023] Open
Abstract
Although there is no evidence that elevated rates of cesarean sections (CS) translate into reduced maternal/child perinatal morbidity or mortality, CS have been increasingly overused almost everywhere, both in high and low-income countries. The primary cesarean section (PCS) has become a major driver of the overall CS (OCS) rate, since it carries intrinsic risk of repeat CS (RCS) in future pregnancies. In our study we examined patterns of PCS, pl compared with planned TOLAC anned PCS (PPCS), vaginal birth after 1 previous CS (VBAC-1) and associated factors in Friuli Venezia Giulia (FVG), a region of North-Eastern Italy, collecting data from its 11 maternity centres (coded from A to K) during 2005-2015. By fitting three multiple logistic regression models (one for each delivery mode), we calculated the adjusted rates of PCS and PPCS among women without history of CS, whilst the calculation of the VBAC rate was restricted to women with just one previous CS (VBAC-1). Results, expressed as odds ratio (OR) with 95% confidence interval (95%CI), were controlled for the effect of hospital, calendar year as well as several factors related to the clinical and obstetric conditions of the mothers and the newborn, the obstetric history and socio-demographic background. In FVG during 2005-2015 there were 24,467 OCS (rate of 24.2%), 19,565 PCS (19.6%), 7,736 PPCS (7.7%) and 2,303 VBAC-1 (28.4%). We found high variability of delivery mode (DM) at hospital level, especially for PCS and PPCS. Breech presentation was the strongest determinant for PCS as well as PPCS. Leaving aside placenta previa/abuptio placenta/ante-partum hemorrhage, further significant factors, more importantly associated with PCS than PPCS were non-reassuring fetal status and obstructed labour, followed by (in order of statistical significance): multiple birth; eclampsia/pre-eclampsia; maternal age 40-44 years; placental weight 600-99 g; oligohydramios; pre-delivery LoS 3-5 days; maternal age 35-39 years; placenta weight 1,000-1,500 g; birthweight < 2,000 g; maternal age ≥ 45 years; pre-delivery LoS ≥ 6 days; mother's age 30-34 years; low birthweight (2,000-2,500 g); polyhydramnions; cord prolaspe; ≥6 US scas performed during pregnancy and pre-term gestations (33-36 weeks). Significant factors for PPCS were (in order of statistical significance): breech presentation; placenta previa/abruptio placenta/ante-partum haemorrhage; multiple birth; pre-delivery LoS ≥ 3 days; placental weight ≥ 600 g; maternal age 40-44 years; ≥6 US scans performed in pregnancy; maternal age ≥ 45 and 35-39 years; oligohydramnios; eclampsia/pre-eclampsia; mother's age 30-34 years; birthweight <2,000 g; polyhydramnios and pre-term gestation (33-36 weeks). VBAC-1 were more likely with gestation ≥ 41 weeks, placental weight <500 g and especially labour analgesia. During 2005-2015 the overall rate of PCS in FVG (19.6%) was substantially lower than the corresponding figure reported in 2010 for the entire Italy (29%) and still slightly under the most recent national PCS rate for 2017 (22.2%). The VBAC-1 rate on women with history of one previous CS in FVG was 28.4% (25.3% considering VBAC on all women with at least 1 previous CS), roughly three times the Italian national rate of 9% reported for 2017. The discrepancy between the OCS rate at country level (38.1%) and FVG's (24.2%) is therefore mainly attributable to RCS. Although there was a marginal decrease of PCS and PPCS crudes rates over time in the whole region, accompained by a progressive enhancement of the crude VBAC rate, we found remarkable variability of DM across hospitals. To further contain the number of unnecessary PCS and promote VBAC where appropriate, standardized obstetric protocols should be introduced and enforced at hospital level. Decision-making on PCS should be carefully scrutinized, introducing a diagnostic second opinion for all PCS, particularly for term singleton pregancies with cephalic presentation and in case of obstructed labour as well as non-reassuring fetal status, grey areas potentially affected by subjective clinical assessment. This process of change could be facilitated with education of staff/patients by opinion leaders and prenatal counseling for women and partners, although clinical audits, financial penalties and rewards to efficient maternity centres could also be considered.

A Systematic Evaluation of Hospital Performance of Childbirth Delivery Modes and Associated Factors in the Friuli Venezia Giulia Region (North-Eastern Italy), 2005-2015. Sci Rep 2019; 9:19442.

Abstract
Cesarean sections (CS) have become increasingly common in both developed and developing countries, raising legitimate concerns regarding their appropriateness. Since improvement of obstetric care at the hospital level needs quantitative evidence, using routinely collected health data we contrasted the performance of the 11 maternity centres (coded with an alphabetic letter A to L) of an Italian region, Friuli Venezia Giulia (FVG), during 2005-15, after removing the effect of several factors associated with different delivery modes (DM): spontaneous vaginal delivery (SVD), instrumental vaginal delivery (IVD), overall CS (OCS) and urgent/emergency CS (UCS). A multivariable logistic regression model was fitted for each individual DM, using a dichotomous outcome (1 = each DM; 0 = rest of hospital births) and comparing the stratum specific estimates of every term with their respective reference categories. Results were expressed as odds ratios (OR) with 95% confidence intervals (95%CI). The Benjamini-Hochberg (BH) false discovery rates (FDR) approach was applied to control alpha error due to the large number of statistical tests performed. In the entire FVG region during 2005-2015, SVD were 75,497 (69.1% out of all births), IVD were 7,281 (6.7%), OCS were 26,467 (24.2%) and UCS were 14,106 (12.9% of all births and 53.3% out of all CS). SVD were more likely (in descending order of statistical significance) with: higher number of previous livebirths; clerk/employed occupational status of the mother; gestational age <29 weeks; placentas weighing <500 g; stillbirth; premature rupture of membranes (PROM). IVD were predominantly more likely (in descending order of statistical significance) with: obstructed labour, non-reassuring fetal status, history of CS, labour analgesia, maternal age ≥35 and gestation >40 weeks. The principal factors associated with OCS were (in descending order of statistical significance): CS history, breech presentation, non-reassuring fetal status, obstructed labour, multiple birth, placental weight ≥ 600 g, eclampsia/pre-eclampsia, maternal age ≥ 35 and oligohydramnios. The most important risk factors for UCS were (in descending order of statistical significance): placenta previa/abruptio placenta/ antepartum hemorrage; non-reassuring fetal status, obstructed labour; breech presentation; PROM, eclampsia/pre-eclampsia; gestation 33-36 weeks; gestation 41+ weeks; oligohydramnios; birthweight <2,500 g, maternal age ≥ 35 and cord prolapse. After removing the effects of all other factors, we found great variability of DM rates across hospitals. Adjusting for all risk factors, all hospitals had a OCS risk higher than the referent (hospital G). Out of these 10 hospitals with increased adjusted risk of OCS, 9 (A, B, C, D, E, F, I, J, K) performed less SVD and 5 (A, C, D, I, J) less IVD. In the above 5 centres CS was therefore probably overused. The present study shows that routinely collected administrative data provide useful information for health planning and monitoring. Although the overall CS rate in FVG during 2005-15 was 24.2%, well below the corresponding average Italian national figure (38.1%), the variability of DM rates across FVG maternity centres could be targeted by policy interventions aimed at reducing the recourse to unnecessary CS. In some clinical conditions such as obstructed labor, non-reassuring fetal status, breech presentation, history of CS, higher maternal age and multiple birth, consideration may be given to more conservative DM. The overuse of CS in nulliparas and repeat CS (RCS) should be carefully monitored and subject to audit.

Abstract
BACKGROUND External cephalic version (ECV) should be offered for patients presenting with a noncephalic pregnancy that are willing to deliver vaginally. Various reports have evaluated predictors for successful ECV. Yet, none have reported a single-operator large cohort experience. We aim to analyze the outcome of referrals for ECV. METHODS We conducted a retrospective cohort study of prospectively collected data. We performed a multivariate analysis of data with respect to ECV procedures performed by a single operator in a 6-year period. Maternal and fetal characteristics were compared between ECV success and failure groups. RESULTS Six hundred and two women underwent ECV. Of them, ECV was successful in 432 (71.7%). A multivariate binary logistic regression model demonstrated that high liquor volume was a predictor of ECV success (Adj OR 1.17 [95% CI 1.09-1.26]). Failure of ECV was correlated with anterior placenta (0.44 [0.56-0.76]) and nulliparity (0.21 [0.11-0.36]). Adverse events were rare and mostly minor, occurring in 1% of procedures. CONCLUSIONS ECV has a high success rate and a low complication rate, enabling vaginal birth and avoiding cesarean. The role of manipulation of modifiable determinants such as liquor volume should be further assessed in future studies.

Abstract
BACKGROUND External cephalic version (ECV) is a common procedure for women carrying a breech-presenting fetus, in an effort to avoid a cesarean birth. The benefit of immediate labor induction after ECV vs. expectant management is undetermined. We aimed to evaluate whether induction of labor immediately after a successful ECV improves the chances of a vaginal delivery compared with expectant management. METHODS Retrospective analysis of 296 women who underwent successful ECV performed in term singleton gestations (2007-2018) in the Rabin Medical Center. Mode of delivery and other obstetrical and neonatal outcomes were compared between women undergoing immediate labor induction after ECV and those managed expectantly. RESULTS Of 296 women after successful ECVs, 54 (18.2%) underwent immediate labor induction and 242 (81.8%) were managed expectantly. Immediate induction was associated with higher parity (2.4 vs 1.7, P = .03) and lower mean birthweight (3128 vs 3346 g, P < .01). Mode of delivery was similar between groups, and no other significant differences in obstetrical and neonatal adverse outcomes were noted. DISCUSSION In our cohort, immediate labor induction after successful ECV apparently had no benefits in terms of obstetrical or neonatal complications, and did not reduce the risk of cesarean birth. Therefore, expectant management seems reasonable and safe.

Abstract
INTRODUCTION Approximately 4% of singleton pregnancies at term are in breech presentation. External cephalic version (ECV) can reduce the risks of noncephalic birth and cesarean delivery, but this maneuver can be painful. Our aim was to analyze the effect of administering inhaled nitrous oxide for analgesia on the ECV success rate. MATERIAL AND METHODS This prospective, randomized, single-blind, controlled trial included women with singleton pregnancies in breech presentation at term who were referred for ECV in a tertiary care center. Women were assigned according to a balanced (1:1) restricted randomization design to inhale either nitrous oxide (N2 O) in a 50:50 mix with oxygen or medical air during the procedure. The main outcomes reported are the ECV success rate, degree of pain, adverse event rate, and women's satisfaction. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01948115. RESULTS The study included 150 women (nitrous oxide group: n = 74; medical air: n = 76). Inhaled nitrous oxide was not associated with a higher ECV success rate than medical air (24.3 vs 19.7%, P = 0.51). Among parous women (n = 34 in each group), the ECV success rate appeared higher in the nitrous oxide group, respectively 47.1% (n = 16) vs 23.5% (n = 8) (P = 0.042). Neither the median pain level nor adverse event rates differed significantly in women with inhaled nitrous oxide compared with medical air. CONCLUSIONS Use of an equimolar mixture of oxygen and nitrous oxide during ECV appears safe. Although it does not seem to change the overall success rate, it may increase success in parous women.

Abstract
OBJECTIVE Published series regarding interventions for facilitating external cephalic version (ECV) have concluded that parenterally administered beta-stimulant tocolytics, increased ECV success rate and reduced the number of cesarean sections. However, there were insufficient data regarding calcium channel blockers to provide good evidence regarding its efficacy. Given the paucity of literature, we aimed to compare the efficacy of nifedipine to that of ritodrine on ECV success rates. METHODS This is a retrospective case control study of prospectively collected data of patients who underwent ECV between January 2012 and December 2013 at Bikur Cholim Medical Center and Hadassah-Hebrew University Medical Center in Jerusalem, Israel. Patient undergoing ECV with tocolysis by ritodrine were compared with those using nifedipine as tocolysis. Patients were matched in a one-to-one ration by parity and placental location. RESULTS Overall, 148 women received ritodrine and 148 women received nifedipine before ECV procedure. Overall success rate was higher among the ritodrine group (82.4 vs. 63.5%, p < .001). Among nulliparous and among parous, success rate was higher in the ritodrine group (78.9 vs. 57.9 and 88.6 vs. 73.5%, p = .001, p = .04, respectively). Vaginal delivery rate was higher among the ritodrine group (86.5 vs. 68.9%, p < .001). Cesarean delivery rate was 31.1% for the nifedipine group versus 13.5% in the ritodrine group (p < .001). Number needed to treat to benefit (NNTb) 5.7 (95% confidence interval 3.7-12.1). Overall, 216 of 296 (72.9%) of ECV were successful. Ritodrine was associated with higher success rates as compared with nifedipine (56.5 vs. 32.5%, p < .001). In a multivariate analysis, ritodrine tocolytic therapy was independently associated higher ECV success rates as compared to nifedipine (OR 4.54, 95% CI 2.38-9.09). Higher amniotic fluid index (OR 1.16, 95% CI 1.05-1.28) and nulliparity (OR 0.16, 95% CI 0.08-0.30) were additional independent predictors of ECV outcome. CONCLUSION Ritodrine significantly improve the success of ECV compared with nifedipine. Both drugs are shown to be safe.

Abstract
Currently, the rate of cesarean sections being performed in Korea is approximately 40%, with Korea ranking 4th among the Organization for Economic Co-operation and Development countries with respect to cesarean deliveries. Breech presentation at term is an important indication for cesarean section among other factors, including medicolegal concerns and pregnancies in women of advanced maternal age. Term breech presentation is associated with a higher fetal mortality rate than that associated with a cephalic presentation. Therefore, in Korea, most of these women deliver by cesarean section to avoid the complications of vaginal breech delivery. However, cesarean section is itself associated with considerable obstetric morbidity and sometimes, mortality. External cephalic version (ECV) is a useful method to reduce the cesarean section rate in women with breech presentation and therefore to reduce the incidence of breech presentation at delivery. Studies have shown that routine use of ECV reduces the cesarean section rate by approximately two-thirds in term pregnancies with breech presentation. ECV is accepted as a safe, efficacious, and cost-effective method and is recommended by both the American College of Obstetricians and Gynecologists and the Royal College of Obstetricians and Gynecologists in all pregnancies with term breech presentation, if not contraindicated. In Korea, although most clinicians are aware of the option of ECV, their relative lack of experience in performing the procedure and fear of complications render them hesitant to perform ECV. This review is aimed at guiding obstetricians by describing the efficacy, safety concerns, and technical aspects of this procedure.

Abstract
INTRODUCTION External Cephalic Version (ECV) reduces breech presentation at term and thus contribute to the reduction of cesarean section. This study was done to determine the factors associated with the successful ECV in women with breech presentation after 36 weeks' gestation and also to develop and validate a clinical score which could be utilized for individual patient counseling in future. METHODS This was a retrospective cohort study conducted in a tertiary care center and teaching hospital in south India. Prospectively collected data from the register maintained for all ECVs performed on pregnant women with breech presentation at or more than 36 weeks' gestation. Clinical and ultrasound parameters at the time of performing the procedure were used in the analysis. Multiple logistic regression with a stepwise backward selection procedure was used selecting potential variable to construct the model and internal validation was done with bootstrapping. Primary outcome was successful ECV defined as cephalic presentation at the end of the procedure. RESULTS Among 611 women who underwent ECV, it was successful in 70.4%. In the multiple logistic regression model, multiparity (OR4.48), AFI ≥ 7 (OR = 3.06), type of breech, posterior placental location (OR = 1.57), sacro-anterior position of breech (OR = 2.83), normal uterine tone (OR = 1.82) and fetal pole not engaged (OR = 2.82) were found to be predictive of successful ECV with good discrimination (AUC = 0.782) and acceptable calibration. Combining these factors from the model a predictive score (score 0-13) is proposed for clinical utility. CONCLUSIONS Combining clinical and ultrasound parameters into a predictive score, which is simple and effective, could be utilized in the clinical practice, once validated externally.

Abstract
Objective To assess differences in patient characteristics between women who did and did not undergo attempted external cephalic version (ECV) for fetal malpresentation at term. Study Design This was a retrospective cohort study of women with a singleton gestation and noncephalic presentation at > 37.0 weeks between October 2014 and October 2015. We compared demographic and clinical characteristics of women who did and did not undergo attempted ECV and assessed the reasons that women did not attempt ECV. Results Among 215 women, only 51 (24%) attempted ECV. There were no differences in age, race, insurance type, or body mass index between women who underwent attempted ECV and those who did not. Women who underwent ECV were significantly more likely to have had a prior vaginal delivery (69 vs. 36%, p < 0.001). Seventy-six women (46%) declined ECV. Women who declined ECV were more likely to be nulliparous than those who accepted the procedure (66 vs. 29%, p < 0.001). Among women who had ECV, the success rate was 55%. There were no adverse events after attempted ECV in this cohort. Conclusion Among women with fetal malpresentation at term, those without a prior vaginal delivery were significantly less likely to undergo attempted ECV.

Abstract
Objective When delivery of a breech fetus is required at a preterm gestational age, Cesarean delivery is often recommended. We performed a prospective patient series to assess the success rate and safety of performing external cephalic version (ECV) procedures on preterm fetuses as an alternative to Cesarean delivery. Study Design We performed a prospective clinical series of patients who required delivery with a malpresenting fetus at a preterm gestational age. Results ECV procedures were successful in singletons 50% of the time. No significant complications or cases of fetal mortality were documented. Conclusion ECV at preterm gestational ages may be an appropriate approach to management in patients requiring delivery. Larger series are needed to further document success rates and risks of the procedure.

METHODS We conducted a retrospective cohort study of women with nonanomalous singleton gestations in nonvertex presentation delivering at a tertiary care institution from 2006 to 2016. Women undergoing an ECV attempt at 37 weeks of gestation or greater were compared with those with nonvertex fetuses who did not undergo an ECV attempt and delivered at 37 weeks of gestation or greater. The primary outcome was a composite of perinatal morbidity and mortality including stillbirth, neonatal death within 72 hours, Apgar score less than 5 at 5 minutes, umbilical artery pH less than 7.0, base deficit 12 mmol/L or greater, or neonatal therapeutic hypothermia. Secondary outcomes were neonatal intensive care unit admission and neonatal anemia (hemoglobin value less than 13.5 g/dL). Bivariable and multivariable analyses were performed. RESULTS Of the 4,117 women meeting eligibility criteria, 1,263 (30.7%) attempted ECV; 509 (40.3%) of these attempts resulted in successful versions. In bivariable analyses, women who underwent attempted ECV were more likely to be non-Hispanic white and multiparous and had lower mean body mass indexes. The composite perinatal morbidity and mortality outcome did not differ significantly between women who did and did not undergo attempted ECV (2.9% vs 2.5%, P=.46). The frequencies of neonatal intensive care unit admission (3.6% vs 3.3%, P=.53) and neonatal anemia (1.6% vs 1.2%, P=.36) were also similar. There continued to be no association between ECV attempt and composite perinatal morbidity and mortality outcome after adjustment for potential confounders (adjusted odds ratio 1.02, 95% CI 0.66-1.60). CONCLUSION Compared with expectant management, an ECV attempt at term is not associated with increased perinatal morbidity or mortality.

Abstract
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.

Abstract
AIM Cesarean section rates are increasing worldwide and Robson's classification system allows a practical approach to study this phenomenon. C-section in Chile has been indicated as unexpectedly high, with important variability within the country and payment systems. The aim was to report our data using Robson's system and the evolution of local C-section rate in a public hospital during a 9-year period. METHODS Retrospective analysis (2005-April 2014), in a metropolitan hospital in Santiago. All deliveries were classified into Robson groups. Time changes were analyzed with Pearson's correlation. P value <0.05 was considered significant. A 'relevance index' (RI) for each group was calculated as 100 × C-S rate × relative contribution. RESULTS The overall C-section rate increased from 24 to 27% (P < 0.05) in 53 571 deliveries, with a greater increase in groups 1 (nulliparous, single, term cephalic, spontaneous labor), 3 (multiparous, single, no previous C-S, term cephalic, spontaneous labor) and 4 (multiparous, single, no previous C-S, term cephalic, induced or no labor). Despite no increase in Group 5 (women with one or more previous C-S) this group had the highest RI (20.3), which defined priority for intervention over others. CONCLUSION C-S rate was lower than that reported in other centers from Chile and Latin America. Robson's classification and the RI allowed prioritization. Although increase in groups 1, 3 and 4, group 5 needs attention because of stronger impact on overall C-S rate. This analysis allowed to define how to lower C-S rate in our institution.

Abstract
Background: Women may be unaware of the potential impact on subsequent deliveries of the decision to undergo primary breech cesarean (PBC) delivery rather than attempt external cephalic version (ECV). We investigated cesarean delivery rates and adverse maternal outcomes in the subsequent delivery following management of breech presentation by ECV versus PBC.Methods: This retrospective study identified women who delivered subsequent to breech presentation managed by attempted ECV or PBC. We assessed cesarean delivery rates and adverse maternal outcomes including hemorrhage, placental complications, infection, and obstetric complications in the subsequent delivery following attempted ECV versus PBC.Results: We identified 307 women who had attempted ECV and 508 with PBC in the index breech pregnancy. Following attempted ECV, 47 (15.3%) women had cesarean delivery in the subsequent pregnancy versus 246 (48.4%) following PBC, adjusted OR 0.24, 95% CI 0.16-0.35 for subsequent cesarean delivery after attempted ECV in the index pregnancy. The frequency of composite adverse outcomes related to cesarean delivery was 30 (9.8%) following attempted ECV versus 104 (20.5%) after PBC, p < .0001. The frequency of composite severe adverse maternal outcome was similar following attempted ECV 25 (8.8%) versus PBC 59 (11.9%).Conclusions: The current study suggests that attempted external cephalic version was associated with a five-fold decrease risk to undergo cesarean in the subsequent delivery and a significantly decreased frequency of composite adverse outcomes related to cesarean delivery in the subsequent delivery.

Abstract
OBJECTIVE To analyse the outcome of referrals for external cephalic version (ECV). DESIGN Retrospective cohort study of prospectively collected data. SETTING Major university hospital, UK. SAMPLE Women with non-cephalic presentation at term and no prior caesarean, referred to a specialist clinic. METHODS Details of referrals, ECV attempts, and perinatal outcomes were prospectively collected and analysed. Multivariate binary logistic regression models were created to determine independent predictors of ECV success, reversion, and spontaneous version. MAIN OUTCOME MEASURES External cephalic version success rates, predictors of success and cephalic presentation at birth, and perinatal outcomes. RESULTS Three thousand eight had confirmed breech presentation; 2614 women underwent ECV. Ineligibility for ECV occurred in 117 breech presentations (3.9%), and 297 eligible women (10.2%) declined it. ECV was successful in 1280 (49.0%, 95% CI 47.0-50.9%) (40% in nulliparous women; 64% in others); 1234 (97.3%) were cephalic at birth. Spontaneous version after failure occurred in 4.3% and was more common in multiparas (aOR 2.47, 95% CI 1.43-4.26) and those with a posterior fetal back (aOR 6.09, 95% CI 1.90-19.53). Reversion after successful ECV occurred in 2.2%. In women with a successful ECV whose fetus remained cephalic at birth, 85.7% delivered vaginally. The corrected perinatal mortality of the ECV cohort was 0.12%. CONCLUSION External cephalic version has a low complication rate and is effective for most breech presentations, enabling vaginal birth and avoiding caesarean section. TWEETABLE ABSTRACT External cephalic version can safely be performed with most breech presentations.
