To compare maternal outcomes using Carbetocin versus Oxytocin for the active management of the third stage of labor, given a temporary national shortage of Oxytocin. We conducted a retrospective observational study on a cohort of 866 women with vaginal deliveries at our center, >36 weeks of gestation, between November 2018 and March 2019. During the shortage period, each woman received a single slow intravenous injection of Carbetocin 100 µg at delivery of the anterior shoulder, rather than Oxytocin 5 UI, as postpartum hemorrhage prophylaxis. 146 (16.9%) patients received Carbetocin versus 720 (83.1%) receiving Oxytocin. The outcomes were rates of postpartum hemorrhage, severe postpartum hemorrhage, and placental retention. Incidence rates of placental retention and postpartum hemorrhage were 4.9% and 9.4% respectively. Placenta retention was significantly more likely following Carbetocin administration (adjusted odds ratio 2.5; 95% confidence interval 1.2–5.0). Postpartum hemorrhage rates were not significantly different (adjusted odds ratio 1.1; 95% confidence interval 0.6–2.1), as were severe postpartum hemorrhage rates (adjusted odds ratio 0.7; 95% confidence interval 0.2–2.2). Carbetocin is as effective as Oxytocin for postpartum hemorrhage prevention. However, we would reserve it for use after placental delivery due to the increased retention rates.

SARS-CoV-2-related placentitis shows distinctive histologic characteristics, and its impact on perinatal outcomes is increasingly under scrutiny. We present two such cases in the third trimester displaying mild maternal clinical symptoms and associated with maternal coagulopathy, reduced fetal movements, and nonreassuring fetal heart rate tracing. Both cases resulted in emergency cesarean deliveries. Our cases and a review of the literature highlight that SARS-CoV-2 undermines placental function and thus greatly impacts late-term pregnancies, even in the absence of severe systemic disease.

Background Among nonpregnant individuals, diabetes mellitus and high body mass index increase the risk of COVID-19 and its severity. Objective This study aimed to determine whether diabetes mellitus and high body mass index are risk factors for COVID-19 in pregnancy and whether gestational diabetes mellitus is associated with COVID-19 diagnosis. Study Design INTERCOVID was a multinational study conducted between March 2020 and February 2021 in 43 institutions from 18 countries, enrolling 2184 pregnant women aged ≥18 years; a total of 2071 women were included in the analyses. For each woman diagnosed with COVID-19, 2 nondiagnosed women delivering or initiating antenatal care at the same institution were also enrolled. The main exposures were preexisting diabetes mellitus, high body mass index (overweight or obesity was defined as a body mass index ≥25 kg/m2), and gestational diabetes mellitus in pregnancy. The main outcome was a confirmed diagnosis of COVID-19 based on a real-time polymerase chain reaction test, antigen test, antibody test, radiological pulmonary findings, or ≥2 predefined COVID-19 symptoms at any time during pregnancy or delivery. Relationships of exposures and COVID-19 diagnosis were assessed using generalized linear models with a Poisson distribution and log link function, with robust standard errors to account for model misspecification. Furthermore, we conducted sensitivity analyses: (1) restricted to those with a real-time polymerase chain reaction test or an antigen test in the last week of pregnancy, (2) restricted to those with a real-time polymerase chain reaction test or an antigen test during the entire pregnancy, (3) generating values for missing data using multiple imputation, and (4) analyses controlling for month of enrollment. In addition, among women who were diagnosed with COVID-19, we examined whether having gestational diabetes mellitus, diabetes mellitus, or high body mass index increased the risk of having symptomatic vs asymptomatic COVID-19. Results COVID-19 was associated with preexisting diabetes mellitus (risk ratio, 1.94; 95% confidence interval, 1.55–2.42), overweight or obesity (risk ratio, 1.20; 95% confidence interval, 1.06–1.37), and gestational diabetes mellitus (risk ratio, 1.21; 95% confidence interval, 0.99–1.46). The gestational diabetes mellitus association was specifically among women requiring insulin, whether they were of normal weight (risk ratio, 1.79; 95% confidence interval, 1.06–3.01) or overweight or obese (risk ratio, 1.77; 95% confidence interval, 1.28–2.45). A somewhat stronger association with COVID-19 diagnosis was observed among women with preexisting diabetes mellitus, whether they were of normal weight (risk ratio, 1.93; 95% confidence interval, 1.18–3.17) or overweight or obese (risk ratio, 2.32; 95% confidence interval, 1.82–2.97). When the sample was restricted to those with a real-time polymerase chain reaction test or an antigen test in the week before delivery or during the entire pregnancy, including missing variables using imputation or controlling for month of enrollment, the observed associations were comparable. Conclusion Diabetes mellitus and overweight or obesity were risk factors for COVID-19 diagnosis in pregnancy, and insulin-dependent gestational diabetes mellitus was associated with the disease. Therefore, it is essential that women with these comorbidities are vaccinated.

Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Hipertensió gestacional; Preeclampsia Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Hipertension gestacional; Preeclampsia Coronavirus SARS-CoV-2; COVID-19; 2019-nCoV; Gestational hypertension; Preeclampsia Background It is unclear whether the suggested link between COVID-19 during pregnancy and preeclampsia is an independent association or if these are caused by common risk factors. Objective This study aimed to quantify any independent association between COVID-19 during pregnancy and preeclampsia and to determine the effect of these variables on maternal and neonatal morbidity and mortality. Study Design This was a large, longitudinal, prospective, unmatched diagnosed and not-diagnosed observational study assessing the effect of COVID-19 during pregnancy on mothers and neonates. Two consecutive not-diagnosed women were concomitantly enrolled immediately after each diagnosed woman was identified, at any stage during pregnancy or delivery, and at the same level of care to minimize bias. Women and neonates were followed until hospital discharge using the standardized INTERGROWTH-21 st protocols and electronic data management system. A total of 43 institutions in 18 countries contributed to the study sample. The independent association between the 2 entities was quantified with the risk factors known to be associated with preeclampsia analyzed in each group. The outcomes were compared among women with COVID-19 alone, preeclampsia alone, both conditions, and those without either of the 2 conditions. Results We enrolled 2184 pregnant women; of these, 725 (33.2%) were enrolled in the COVID-19 diagnosed and 1459 (66.8%) in the COVID-19 not-diagnosed groups. Of these women, 123 had preeclampsia of which 59 of 725 (8.1%) were in the COVID-19 diagnosed group and 64 of 1459 (4.4%) were in the not-diagnosed group (risk ratio, 1.86; 95% confidence interval, 1.32–2.61). After adjustment for sociodemographic factors and conditions associated with both COVID-19 and preeclampsia, the risk ratio for preeclampsia remained significant among all women (risk ratio, 1.77; 95% confidence interval, 1.25–2.52) and nulliparous women specifically (risk ratio, 1.89; 95% confidence interval, 1.17–3.05). There was a trend but no statistical significance among parous women (risk ratio, 1.64; 95% confidence interval, 0.99–2.73). The risk ratio for preterm birth for all women diagnosed with COVID-19 and preeclampsia was 4.05 (95% confidence interval, 2.99–5.49) and 6.26 (95% confidence interval, 4.35–9.00) for nulliparous women. Compared with women with neither condition diagnosed, the composite adverse perinatal outcome showed a stepwise increase in the risk ratio for COVID-19 without preeclampsia, preeclampsia without COVID-19, and COVID-19 with preeclampsia (risk ratio, 2.16; 95% confidence interval, 1.63–2.86; risk ratio, 2.53; 95% confidence interval, 1.44–4.45; and risk ratio, 2.84; 95% confidence interval, 1.67–4.82, respectively). Similar findings were found for the composite adverse maternal outcome with risk ratios of 1.76 (95% confidence interval, 1.32–2.35), 2.07 (95% confidence interval, 1.20–3.57), and 2.77 (95% confidence interval, 1.66–4.63). The association between COVID-19 and gestational hypertension and the direction of the effects on preterm birth and adverse perinatal and maternal outcomes, were similar to preeclampsia, but confined to nulliparous women with lower risk ratios. Conclusion COVID-19 during pregnancy is strongly associated with preeclampsia, especially among nulliparous women. This association is independent of any risk factors and preexisting conditions. COVID-19 severity does not seem to be a factor in this association. Both conditions are associated independently of and in an additive fashion with preterm birth, severe perinatal morbidity and mortality, and adverse maternal outcomes. Women with preeclampsia should be considered a particularly vulnerable group with regard to the risks posed by COVID-19.

Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (n = 53/75)], preterm delivery [62.7% (n = 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n = 31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease. ispartof: SCIENTIFIC REPORTS vol:11 issue:1 ispartof: location:England status: published

This study aims to evaluate the feasibility and clinical interest of shear wave elastography, by quantitatively estimating the baseline stiffness of the myometrium before and after placental expulsion. We conducted a prospective cohort study of women at term, without known risk factors for postpartum hemorrhage, who gave birth via spontaneous labor in our tertiary center. Myometrium tonicity was evaluated based on measurements of shear wave speed (SWS) in the anterior uterine corpus. All data points were collected by a single operator. Measurements were carried out at three different time points: after fetal delivery (T1), after placental delivery (T2) and 30 min after placental delivery (T3). Our primary objective was to assess the feasibility of this new imaging technique. Ten valid SWS measurements obtained at each of the three different time points were considered as a positive primary outcome. Our secondary objectives were to evaluate the difference in median myometrial shear wave velocity between each time point, as well as to determine the correlation between myometrial shear wave velocity and patients’ characteristics. 38 women were recruited during the study period, of whom 34 met the study criteria. 1017 SWS measurements were obtained. The median time to perform measurements was 16 s for one value, and 2 min 56 s for ten. For 11 women (32%) it was not possible to achieve ten SWS at T1 as placental expulsion immediately followed the birth of the newborn. One patient experienced placental retention and only measurements at T1 were performed. For all other patients, we were successfully able to obtain all measures as intended. There was no difference in the mean shear wave speed between the three time points. After adjustments for confounders, we observed a significant correlation for total blood loss (correlation coefficient = − 0.26, p p = 0.03), and newborn weight (correlation coefficient = − 0.08, p = 0.001). It is feasible to assess uterine tonicity by shear wave imaging, after placental expulsion. We did not observe a variance in uterine tonicity between the three time points. Women who had higher blood loss, received more units of oxytocin and/or those with newborns of a higher weight exhibited lower shear wave speed measures.

Importance Detailed information about the association of COVID-19 with outcomes in pregnant individuals compared with not-infected pregnant individuals is much needed. Objective To evaluate the risks associated with COVID-19 in pregnancy on maternal and neonatal outcomes compared with not-infected, concomitant pregnant individuals. Design, Setting, and Participants In this cohort study that took place from March to October 2020, involving 43 institutions in 18 countries, 2 unmatched, consecutive, not-infected women were concomitantly enrolled immediately after each infected woman was identified, at any stage of pregnancy or delivery, and at the same level of care to minimize bias. Women and neonates were followed up until hospital discharge. Exposures COVID-19 in pregnancy determined by laboratory confirmation of COVID-19 and/or radiological pulmonary findings or 2 or more predefined COVID-19 symptoms. Main Outcomes and Measures The primary outcome measures were indices of (maternal and severe neonatal/perinatal) morbidity and mortality; the individual components of these indices were secondary outcomes. Models for these outcomes were adjusted for country, month entering study, maternal age, and history of morbidity. Results A total of 706 pregnant women with COVID-19 diagnosis and 1424 pregnant women without COVID-19 diagnosis were enrolled, all with broadly similar demographic characteristics (mean [SD] age, 30.2 [6.1] years). Overweight early in pregnancy occurred in 323 women (48.6%) with COVID-19 diagnosis and 554 women (40.2%) without. Women with COVID-19 diagnosis were at higher risk for preeclampsia/eclampsia (relative risk [RR], 1.76; 95% CI, 1.27-2.43), severe infections (RR, 3.38; 95% CI, 1.63-7.01), intensive care unit admission (RR, 5.04; 95% CI, 3.13-8.10), maternal mortality (RR, 22.3; 95% CI, 2.88-172), preterm birth (RR, 1.59; 95% CI, 1.30-1.94), medically indicated preterm birth (RR, 1.97; 95% CI, 1.56-2.51), severe neonatal morbidity index (RR, 2.66; 95% CI, 1.69-4.18), and severe perinatal morbidity and mortality index (RR, 2.14; 95% CI, 1.66-2.75). Fever and shortness of breath for any duration was associated with increased risk of severe maternal complications (RR, 2.56; 95% CI, 1.92-3.40) and neonatal complications (RR, 4.97; 95% CI, 2.11-11.69). Asymptomatic women with COVID-19 diagnosis remained at higher risk only for maternal morbidity (RR, 1.24; 95% CI, 1.00-1.54) and preeclampsia (RR, 1.63; 95% CI, 1.01-2.63). Among women who tested positive (98.1% by real-time polymerase chain reaction), 54 (13%) of their neonates tested positive. Cesarean delivery (RR, 2.15; 95% CI, 1.18-3.91) but not breastfeeding (RR, 1.10; 95% CI, 0.66-1.85) was associated with increased risk for neonatal test positivity. Conclusions and Relevance In this multinational cohort study, COVID-19 in pregnancy was associated with consistent and substantial increases in severe maternal morbidity and mortality and neonatal complications when pregnant women with and without COVID-19 diagnosis were compared. The findings should alert pregnant individuals and clinicians to implement strictly all the recommended COVID-19 preventive measures.

Clinicians and patients have traditionally believed that elective cesarean section may protect against certain previously ineluctable consequences of labor, including a plethora of urinary, anorectal and sexual dysfunctions. We aimed to evaluate fecal, urinary and sexual symptoms 6 years postpartum, comparing uncomplicated vaginal delivery and elective cesarean delivery, and to assess their impact on quality of life. We conducted a cross-sectional study to compare perineal functional symptomatology between women having singleton elective cesarean deliveries (eCS) and singleton uncomplicated vaginal deliveries (uVD). Women who delivered 6 years before this study were chosen randomly from our hospital database. This database includes demographic, labor, and delivery information, as well as data regarding maternal and neonatal outcomes, all of which is collected at the time of delivery by the obstetrician. Four validated self-administrated questionnaires were sent by post to the participants: the short forms of the Urogenital Distress Inventory, Incontinence Impact Questionnaire, Wexner fecal incontinence scale, and Female Sexual Function Index. Current socio-demographic details, physical characteristics, obstetrical history and mode of delivery at subsequent births were also registered using a self-reported questionnaire. A total of 309 women with uVD and 208 with eCS returned postal questionnaires. The response rate was 49%. Socio-demographic characteristics and fecal incontinence were similar between groups. After eCS, women reported significantly less urgency urinary incontinence (adjusted Relative Risk 0.55; 95% confidence interval 0.34–0.88) and stress incontinence (adjusted Relative Risk 0.53; 95% confidence interval 0.35–0.80) than after uVD. No difference in total Incontinence Impact Questionnaire score was found between both modes of delivery. Lower abdominal or genital pain (adjusted Relative Risk 1.58; 95% confidence interval 1.01–2.49) and pain related to sexual activity (adjusted Relative Risk 2.50; 95% confidence interval 1.19–5.26) were significantly more frequent after eCS than uVD. Six years postpartum, uVD is associated with urinary incontinence, while eCS is associated with sexual and urination pain.

Background In western countries, induction of labor is a common obstetrical intervention. Uterine tachysystole frequently manifests after cervical ripening by misoprostol vaginal inserts. Currently, there is insufficient evidence regarding the clinical impact of tachysystole during induction of labor. Therefore, the objective of the current study is to examine if tachysystole is associated with an increased risk of cesarean section following induction of labor by misoprostol vaginal inserts. Methods We conducted a retrospective cohort study of 446 women over 37 weeks of gestation admitted for labor induction by misoprostol vaginal inserts between May 2016 and May 2017. Fetal heart rate and uterine activity tracings were assessed for tachysystole, defined as ≥ 6 contractions per 10 minutes, averaged over a 30-minute window. Univariate analysis was performed by using t-test and Chi-square, comparing demographics, pregnancy characteristics, intrapartum monitoring, mode of delivery, neonatal outcomes (Apgar score < 7 at 5 minutes, umbilical cord artery pH < 7.10, neonatal intensive care unit admission) and maternal outcomes, with regard to the presence of tachysystole. The association between tachysystole and cesarean section was evaluated after adjusting for potential confounders by a modified Poisson regression model, expressed as an adjusted risk ratio and 95% confidence intervals. Results A total of 140 women (31.4%) presented with tachysystole. The median duration of tachysystole was 2 hours 12 minutes. The rate of cesarean section was 25.0% (N=35) among patients with tachysystole and 19.6% (N=60) for those without tachysystole. Presence of tachysystole during induction of labor with misoprostol vaginal inserts was not associated with cesarean section (adjusted risk ratio,1.0; 95% confidence interval, 0.7 to 1.4). Neonatal and maternal outcomes were similar between mothers who did and did not experience tachysystole. Conclusions This study illustrates that tachysystole is not associated with an increased risk of cesarean section after induction of labor by misoprostol vaginal inserts. The impact of excessive uterine activity on the fetal wellbeing defined by the frequency of uterine contraction alone is probably insufficient. Further research on the development of accurate measures of uterine contractility is necessary to better understand its effect on fetal well-being.

Background: Pregnant women represent a vulnerable population at higher risk of complications of infectious diseases. Data regarding the consequences of the emerging pandemic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during pregnancy are scarce. Recent evidence suggests that pregnant women might be at higher risk of severe disease, while exposed fetuses and newborns could suffer from preterm birth, growth restriction and neonatal infections. Methods: We developed an international web registry to allow structured data collection. Pregnant women at any stage during gestation tested for SARS-CoV-2 infection were enrolled. Maternal, obstetrical and neonatal outcomes were recorded. Findings: 1033 pregnant women tested for SARS-CoV-2 were included, among which 926 tested positive and 107 tested negative. Positive pregnant women were at higher risk of severe maternal outcomes compared to negative women [aRR 5.6, 95% CI 1.4-22.7]. Risk factors for severe maternal outcomes among positive women were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. No difference in term of obstetrical and neonatal outcomes were observed between positive and negative women. Positive pregnant women with severe maternal outcomes were at higher risk of cesarean sections [70.7% (n=53/75)], preterm deliveries [62.7% (n= 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n=31/75)]. A positive neonatal SARS-CoV-2 test was observed in 2.9% (n=11/384) of newborns with an available test at birth. Interpretation: Pregnant women, particularly those with associated comorbidities, seem to be at higher risk of severe complications of SARS-CoV-2 infection. Preliminary data regarding obstetrical and neonatal outcomes among women with a mild disease are reassuring. Funding Statement: None. Declaration of Interests: The authors declare that we have no conflicts of interest. Ethics Approval Statement: The study was approved by both the Swiss Ethical Board (CER-VD-2020-00548) and the local ethics boards at each participating center.

Background: Recent evidence suggests that pregnant women might be at higher risk of severe disease associated with the emerging pandemic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), while exposed fetuses/newborns could suffer from preterm birth, growth restriction and neonatal infections. The magnitude of this increased risk and specific risk factors for severity remains unclear. Methods: We performed a case control study comparing pregnant women with severe coronavirus disease 19 (case) to pregnant women with a milder form (controls) enrolled in COVI-Preg international registry cohort between from March 24 to July 26, 2020. Risk factors for severity, obstetrical, fetal and neonatal outcomes were assessed. Findings: A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented a severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5].

Interpretation: Pregnant women, particularly those with associated comorbidities, seem to be at higher risk of severe complications of SARS-CoV-2 infection. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease; complications include cesarean sections, prematurity and neonatal admission to the intensive care unit. Funding Statement: None. Declaration of Interests: The authors declare that they have no conflicts of interest. Ethics Approval Statement: The study was approved by both the Swiss Ethical Board (CER-VD- 2020-00548) and the local ethics boards at each participating center.

Introduction More than half of women with a history of prior obstetric anal sphincter injuries (OASIS) will have another pregnancy. Currently, little is known concerning post-partum perineal symptoms in cases of a subsequent vaginal delivery. The aim of this study was to assess the frequency of perineal functional symptoms following a vaginal delivery after OASIS while comparing them to patients who did not have a subsequent delivery. Material and method Retrospective cohort study between January 2000 and December 2011. A questionnaire was sent by post to all women who sustained an OASIS at the Poitiers University Hospital, France. Perineal functional symptoms and quality of life were assessed using validated self-administered questionnaires: Female Pelvic Floor Questionnaire, Pescatori anal incontinence score, EuroQoL five-dimension score, and pain visual analogue scale. Results 159 women of 237 contacted (67%) responded to the questionnaire, on average 46 months after the delivery complicated with OASIS. 135 (85%) of women had a 3rd degree laceration and 24% a 4th degree laceration. 99 women (63%) did not have an ensuing delivery since the event (OASIS − No Subsequent Delivery: SD-). 60 women (37%) had a subsequent delivery (OASIS −Subsequent Delivery: SD + ), with 53 (88%) having a vaginal birth. Among these women, 3 (6%) experienced a recurrent OASIS. The mean score for perineal symptoms (FPFQ) was 6.95 in the OASIS-SD (−) group and 7.40 in the OASIS-SD (+) group (p = 0.64). No significant difference in quality of life (EuroQol 5D) was found between the two groups (p = 0.91). Conclusion We did not observe a deterioration of perineal functional symptomatology after vaginal delivery in women with known prior OASIS, compared to women who did not have a subsequent delivery. Even if the risk of occurrence of these lesions is higher in women with history of previous OASIS compared to those without perineal injury, it is still comparable to incidence among primiparous women.

In the last 30 years, with increasing cesarean section rates, the incidence of the placenta accreta spectrum has also increased. It is estimated that by the year 2020 there will be nearly 9000 cases annually in the United States. Currently, no consensus exists regarding optimal management. Conventional treatment by cesarean-hysterectomy is challenging, with a high maternal morbidity due to massive hemorrhage, and surgical complications such as urinary tract, bowel and pelvic nerve injury, in addition to loss of fertility and its accompanying psychological trauma. Innovative approaches seek to preserve the uterus with the adherent placenta in situ, thus maintaining fertility and potentially reducing hemorrhage and adjacent organ injury. This review reports strategies for conservative treatment of such conditions, based on the current literature.

Choosing between vaginal delivery and caesarean section in cases of breech presentation is still a matter of controversy. In this article, we present the Lausanne University Hospital's protocol following the introduction of an institutional vaginal breech delivery policy. Vaginal breech delivery is a viable alternative to caesarean section in the presence of an experienced obstetrician and rigorous patient-selection criteria.Le choix entre un accouchement par voie basse et une césarienne reste controversé lors de présentation en siège. Nous présentons dans cet article le protocole de la Maternité du Centre hospitalier universitaire vaudois suite à l’introduction d’une politique favorisant les accouchements en siège. L’accouchement par voie basse du siège est désormais une alternative possible à la césarienne en présence d’obstétriciens expérimentés et de critères de sélection rigoureux des patientes.
