Neonatal outcomes according to actual delivery mode after planned vaginal delivery in women with a twin pregnancy.

OBJECTIVE: To compare, in women with twin pregnancy with the first twin in cephalic position, neonatal morbidity and mortality rates after actual 1) Vaginal delivery (VD) both twins versus 2) unplanned Cesarean Delivery (CD) of both twins and 3) after VD of twin A and CD of twin B (combined delivery). STUDY DESIGN: We describe a nationwide cohort study of women pregnant with twins who planned to deliver vaginally between 32+0 - 41+6 weeks with the first twin in cephalic position, between 2000-2012 in the Netherlands. We used multivariate logistic regression analysis to compare neonatal morbidity and mortality according to actual mode of delivery, overall, and for preterm and term groups separately. RESULTS: We included 19,723 women of whom 15,785 women (80.0 %) delivered both twins by VD, 2926 (14.6 %) delivered both twins by unplanned CD, and 1012 (5.1 %) women delivered by combined delivery. After unplanned CD of both twins compared to VD more perinatal mortality (1 or more twins affected) was seen (adjusted Odds Ratio (aOR) 2.23 (95 % CI 1.26-4.129)), as was 'Asphyxia related morbidity' (aOR 2.44 (95 % CI 1.80-3.31), 'other morbidity' (aOR 1.34 (95 %CI 1.17-1.54), and 'any morbidity or mortality' (aOR1.39 (95 % CI 1.22-1.58)). Less 'Trauma- related morbidity' after unplanned CD vs. VD (aOR 0.11 (95 % 0.02-0.79)) was seen. After combined delivery vs. VD, more perinatal mortality (aOR 7.75 (95 % CI 4.51-13.34)), more Asphyxia- related morbidity (aOR 6.67 (95 % CI4.91-9.06), 'prematurity related morbidity' (aOR 2.11 (95 % CI 1.59-2.79) 'other morbidity' (aOR 2.01 (95 % CI 1.65-2.46), and 'any morbidity or mortality' (aOR 2.44 (95 % CI 2.04-2.91)) were noted. All outcomes expect 'trauma-associated morbidity' were more increased for twin B as compared to twin A. CONCLUSION: After unplanned CD of both twins vs. VD of both twins, a twofold increase in neonatal mortality is noted. Combined delivery vs. VD of both twins is associated with a sevenfold increase in perinatal mortality and a five-fold increase in asphyxia-related outcomes. Twin A is more affected after unplanned CD of both twins, while twin B is more affected after combined delivery.

Perinatal death in a term fetal growth restriction randomized controlled trial: the paradox of prior risk and consent.

BACKGROUND: The disproportionate intrauterine growth intervention trial at term was an intention to treat analysis and compared labor induction with expectant monitoring in pregnancies complicated by fetal growth restriction at term and showed equivalence for neonatal outcomes. OBJECTIVE: To evaluate trial participation bias and to examine the generalizability of the results of an obstetrical randomized trial. STUDY DESIGN: We used data from participants and nonparticipants of a randomized controlled trial-the disproportionate intrauterine growth intervention trial at term (n=1116) -to perform a secondary analysis. This study compared induction of labor and expectant management in women with term growth restriction. Data were collected in the same manner for both groups. Baseline characteristics and neonatal and maternal outcomes were compared. The primary outcome was a composite measure of adverse neonatal outcome. Secondary outcomes were delivery by cesarean delivery and instrumental vaginal delivery; length of stay in the neonatal intensive care, neonatal ward, and the maternal hospital; and maternal morbidity. RESULTS: Nonparticipants were older, had a lower body mass index, had a higher level of education, smoked less, and preferred expectant management. The time between study inclusion and labor onset was shorter in participants than in nonparticipants. Notably, 4 perinatal deaths occurred among nonparticipants and none among participants. Among nonparticipants, there were more children born with a birthweight below the third centile. The nonparticipants who had expectant management were monitored less frequently than the participants in both the intervention and the expectant arm. CONCLUSION: We found less favorable outcomes and more perinatal deaths in nonparticipants. Protocol-driven management, differences between participants and nonparticipants, or the fact that nonparticipants had a preference for expectant management might explain the findings.

Differences in continuation rates and early removal between contraceptive and therapeutic use of the levonorgestrel-releasing intrauterine system 52 mg.

Objective: To investigate differences in continuation rates between contraceptive and therapeutic use of the levonorgestrel-releasing intrauterine system 52 mg (LNG-IUS) and factors associated with early removal.Methods: Study design: Retrospective consecutive cohort design.Cohort: Women with the insertion of the LNG-IUS for contraceptive or therapeutic use from 1 January 2006 through 1 January 2009 at the Zuyderland Medical Centre, The Netherlands, with a follow-up of 5 years. The continuation period and reasons of early removal were noted. Univariable and multivariable analysis were performed.Results: Follow-up was possible in 2481 women, 1855 (74.8%) in the contraception group, and 626 (25.2%) in the therapy group. Multivariable Cox proportional hazards models showed, that therapeutic use was associated with an increased risk of early removal of the LNG-IUS (HR 1.23; 95% CI 1.08-1.41), as was having one child (HR 1.20; 95% CI 1.04-1.38), and a decreased risk with advancing age (HR 0.96; 95% CI 0.95-0.97). In both groups, an unacceptable bleeding pattern and adverse events were the main reasons of early removal, resulting in very low continuation rates over the years.Conclusion: Therapeutic use, having one child and a younger age are independent risk factors of early removal of the LNG-IUS, in contrast with previous LNG-IUS use which is associated with a lower risk. In both the contraception group and the therapy group, the main reasons for LNG-IUS discontinuation are continuation with a new LNG-IUS, and no more need for an LNG-IUS (for contraception or therapy). An unacceptable bleeding pattern or adverse events are associated with the lowest continuation rates in both groups.

Postnatal Catch-Up Growth After Suspected Fetal Growth Restriction at Term.

Objective: The aim of this study was to study growth patterns of children born after suspected fetal growth restriction (FGR) at term and to compare the effect of induction of labor (IoL) and expectant management (EM), also in relation to neurodevelopmental and behavioral outcome at age 2. Methods: We performed a 2 years' follow-up of growth of children included in the Disproportionate Intrauterine Growth Restriction Trial at Term (DIGITAT) study, a Randomized Controlled Trial (RCT) comparing IoL with EM in pregnancies with suspected FGR at term. We collected data on child growth until the age of 2 years. Standard deviation scores (SDSs) for height and weight were calculated at different ages. We assessed the effects of IoL compared with EM and the effects of a birth weight below or above the 3rd or 10th centile on catch-up growth. Target height SDSs were calculated using the height of both parents. Results: We found a significant increase in SDS in the first 2 years. Children born after EM showed more catch-up growth in the first month [height: mean difference -0.7 (95% CI: 0.2; 1.3)] and weight [mean difference -0.5 (95% CI: 0.3; 0.7)]. Children born with a birth weight below the 3rd and 10th centiles showed more catch-up growth after 1 year [mean difference -0.8 SDS (95% CI: -1.1; -0.5)] and after 2 years [mean difference -0.7 SDS (95% CI: -1.2; -0.2)] as compared to children with a birth weight above the 3rd and 10th centiles. SDS at birth had the strongest effect on adverse neurodevelopmental outcome at 2 years of age. Conclusion: After FGR at term, postnatal catch-up growth is generally present and associated with the degree of FGR. Obstetric management in FGR influences postnatal growth. Longer-term follow-up is therefore needed and should be directed at growth and physical health. Clinical Trial Registration: www.ClinicalTrials.gov, identifier SRCTN10363217.

Comparison of planned caesarean delivery and planned vaginal delivery in women with a twin pregnancy: A nation wide cohort study.

OBJECTIVE: To compare, in women with twin pregnancy with the first twin in cephalic position, neonatal morbidity and mortality rates after planned caesarean delivery (CD) versus planned vaginal delivery (VD). STUDY DESIGN: A nationwide cohort study on women pregnant with twins and the first child in cephalic position, who delivered between 32 + 0-41 + 0 weeks between 2000 and 2012 in the Netherlands, using multivariate logistic regression analysis to compare neonatal morbidity and mortality according to planned delivery mode, and looking at subgroups 32 + 0-36 + 6 and 37 + 0-41 + 0 weeks. RESULTS: We included 21,107 women, of whom 1384 (6.6%) had a planned CD. Of the 19,723 women (93.4%) who had a planned VD, 19.7% delivered by intrapartum CD. We found no significant differences in 'any mortality' (aOR planned CD vs. planned VD 1.34 (95% CI 0.63-2.60)), the outcome 'Apgar score (AS) < 4 or death within 28 days' (aOR 1.28 (95% CI 0.77-2.11) or asphyxia-related morbidity (aOR 0.57 (95% CI 0.32-1.03)). After planned CD more prematurity-related morbidity (aOR 1.55 (95% CI 1.21-1.98)), other morbidity (aOR 1.50 (95% CI 1.26-1.78)) and 'any morbidity or mortality' (aOR 1.41 (95% CI 1.20-1.66) was noted. Trauma-associated morbidity was absent after planned CD and occurred 45 times (0.2%) after planned VD. Before 36 + 6 weeks, planned CD resulted in more perinatal mortality (aOR 2.10 (95% CI 0.92-4.76)), while asphyxia-related morbidity did not differ (aOR 0.80 (95% CI 0.41-1.54). Planned CD resulted in more 'any morbidity or mortality' (aOR 1.52 (95% CI 1.25-1.84)), 'AS < 4 or death within 28 days' (aOR 1.77 (95% CI 1.02-3.09)), prematurity-related morbidity (aOR 1.73 (95% CI 1.34-2.23)), and 'other morbidity' (aOR 1.56 (95% CI 1.28-1.90)). After 37 weeks, no significance differences in mortality, 'any morbidity or mortality <28 days' (aOR 0.96 (95% CI 1 (0.67-1.38)), or 'AS < 4 or death within 28 days' (aOR 0.41 (95% CI (0.10-1.70)) were found. There was less asphyxia-related morbidity after planned CD (aOR 0.24 (95% CI 0.06-1.002)). CONCLUSION: Planned VD results in comparable neonatal outcomes as planned CD for twin pregnancy with the first twin in cephalic position, even with a low intrapartum CD rate of 19.7%. At term, a planned CD may result in less asphyxia- and trauma-related outcomes.

Repeated cervical length measurements for the verification of short cervical length.

OBJECTIVE: To determine if the verification of short cervical length with a repeated measurement improved the identification of patients with short cervical length at increased risk of preterm delivery. METHODS: The present secondary analysis analyzed prospective cohort study data from patients with singleton pregnancies without a history of preterm delivery who presented for obstetric care in the Netherlands and delivered between November 18, 2009, and January 1, 2013. Cervical length was measured during standard anomaly scan and a second measurement was performed if the cervical length was 30 mm of shorter. Logistic regression and Cox proportional hazards modeling were used to evaluate associations between cervical length measurements and spontaneous preterm delivery before 37 weeks of pregnancy. RESULTS: Cervical length measurements from 12 358 patients were included; 221 (1.8%) had an initial cervical length measurement of 30 mm or shorter. A second cervical length measurement was performed for 167 (75.6%) patients; no differences were identified in the odds of spontaneous preterm delivery when evaluated using the first, second, or a mean of both measurements, regardless of whether cervical length was analyzed as a continuous or dichotomous variable. CONCLUSION: Among patients with singleton pregnancies, verification of short cervical length did not improve the identification of short cervical length.

Mood disturbances during combined oral contraceptive use and the effect of androgen supplementation. Results of a double-blind, placebo-controlled, single-case alternation design pilot study.

OBJECTIVES: To evaluate the effect of androgen supplementation in healthy combined oral contraceptive (COC) users who experience mood disturbances during COC-use only. METHODS: Six women with mood disturbances during COC-use only, received COC with co-treatment of 50 mg dehydroepiandrosterone (DHEA) during three cycles and placebo during another three cycles in an individualized random order. Daily mood rating was measured by a single item: 'In what kind of mood have you been in the past 24 h?' The results were analysed using a randomisation test for single-case experimental designs. RESULTS: The p values for the alternation design randomisation tests on the raw data of the six healthy individuals varied between 0.21 and 1, indicating that the average daily mood ratings of the active treatment DHEA are not statistically significantly larger than the average daily mood ratings of placebo. The combined p value of the subjects using a DRSP-containing pill was 0.97, and of the subjects using an LNG-containing pill was 0.65, indicating no statistically significant treatment effect for any of the pill types. CONCLUSIONS: In this single-case alternation design study, concomitant treatment with DHEA for intermittent periods of 4 weeks did not result in improvement of mood disturbances related to COC-use, but had also no side-effects.

Women's Experiences with and Preference for Induction of Labor with Oral Misoprostol or Foley Catheter at Term.

Objective We assessed experience and preferences among term women undergoing induction of labor with oral misoprostol or Foley catheter. Study Design In 18 of the 29 participating hospitals in the PROBAAT-II trial, women were asked to complete a questionnaire within 24 hours after delivery. We adapted a validated questionnaire about expectancy and experience of labor and asked women whether they would prefer the same method again in a future pregnancy. Results The questionnaire was completed by 502 (72%) of 695 eligible women; 273 (54%) had been randomly allocated to oral misoprostol and 229 (46%) to Foley catheter. Experience of the duration of labor, pain during labor, general satisfaction with labor, and feelings of control and fear related to their expectation were comparable between both the groups. In the oral misoprostol group, 6% of the women would prefer the other method if induction is necessary in future pregnancy, versus 12% in the Foley catheter group (risk ratio: 0.70; 95% confidence interval: 0.55-0.90; p = 0.02). Conclusion Women's experiences of labor after induction with oral misoprostol or Foley catheter are comparable. However, women in the Foley catheter group prefer more often to choose a different method for future inductions.

Epidural analgesia during labour, routinely or on request: a cost-effectiveness analysis.

OBJECTIVE: To assess the cost-effectiveness of routine labour epidural analgesia (EA), from a societal perspective, as compared with labour analgesia on request. STUDY DESIGN: Women delivering of a singleton in cephalic presentation beyond 36+0 weeks' gestation were randomly allocated to routine labour EA or analgesia on request in one university and one non-university teaching hospital in the Netherlands. Costs included all medical, non-medical and indirect costs from randomisation to 6 weeks postpartum. Effectiveness was defined as a non-operative, spontaneous vaginal delivery without EA-related maternal adverse effects. Incremental cost-effectiveness ratio (ICER) was defined as the ratio of the difference in costs and the difference in effectiveness between both groups. Data were analysed according to intention to treat and divided into a base case analysis and a sensitivity analysis. RESULTS: Total delivery costs in the routine EA group (n=233) were higher than in the labour on request group (n=255) (difference -€ 322, 95% CI -€ 60 to € 355) due to more medication costs (including EA), a longer stay in the labour ward, and more operations including caesarean sections. Total postpartum hospital costs in the routine EA group were lower (difference -€ 344, 95% CI -€ 1338 to € 621) mainly due to less neonatal admissions (difference -€ 472, 95% CI -€ 1297 to € 331), whereas total postpartum home and others costs were comparable (difference -€ 20, 95% CI -€ 267 to € 248, and -€ 1, 95% CI -€ 67 to € 284, respectively). As a result, the overall mean costs per woman were comparable between the routine EA group and the analgesia on request group (€ 8.708 and € 8.710, respectively, mean difference -€ 2, 95% CI -€ 1.012 to € 916). Routine labour EA resulted in more deliveries with maternal adverse effects, nevertheless the ICER remained low (€ 8; bootstrap 95% CI -€ 6.120 to € 8.659). The cost-effectiveness acceptability curve indicated a low probability that routine EA is cost-effective. CONCLUSION: Routine labour EA generates comparable costs as analgesia on request, but results in more operative deliveries and more EA-related maternal adverse effects. Based on cost-effectiveness, no preference can be given to routine labour EA as compared with analgesia on request.

Induction of labour at term with oral misoprostol versus a Foley catheter (PROBAAT-II): a multicentre randomised controlled non-inferiority trial.

BACKGROUND: Labour is induced in 20-30% of all pregnancies. In women with an unfavourable cervix, both oral misoprostol and Foley catheter are equally effective compared with dinoprostone in establishing vaginal birth, but each has a better safety profile. We did a trial to directly compare oral misoprostol with Foley catheter alone. METHODS: We did an open-label randomised non-inferiority trial in 29 hospitals in the Netherlands. Women with a term singleton pregnancy in cephalic presentation, an unfavourable cervix, intact membranes, and without a previous caesarean section who were scheduled for induction of labour were randomly allocated to cervical ripening with 50 µg oral misoprostol once every 4 h or to a 30 mL transcervical Foley catheter. The primary outcome was a composite of asphyxia (pH ≤7·05 or 5-min Apgar score <7) or post-partum haemorrhage (≥1000 mL). The non-inferiority margin was 5%. The trial is registered with the Netherlands Trial Register, NTR3466. FINDINGS: Between July, 2012, and October, 2013, we randomly assigned 932 women to oral misoprostol and 927 women to Foley catheter. The composite primary outcome occurred in 113 (12·2%) of 924 participants in the misoprostol group versus 106 (11·5%) of 921 in the Foley catheter group (adjusted relative risk 1·06, 90% CI 0·86-1·31). Caesarean section occurred in 155 (16·8%) women versus 185 (20·1%; relative risk 0·84, 95% CI 0·69-1·02, p=0·067). 27 adverse events were reported in the misoprostol group versus 25 in the Foley catheter group. None were directly related to the study procedure. INTERPRETATION: In women with an unfavourable cervix at term, induction of labour with oral misoprostol and Foley catheter has similar safety and effectiveness. FUNDING: FondsNutsOhra.

Development and Measurement of Guidelines-Based Quality Indicators of Caesarean Section Care in the Netherlands: A RAND-Modified Delphi Procedure and Retrospective Medical Chart Review.

BACKGROUND: There is an ongoing discussion on the rising CS rate worldwide. Suboptimal guideline adherence may be an important contributor to this rise. Before improvement of care can be established, optimal CS care in different settings has to be defined. This study aimed to develop and measure quality indicators to determine guideline adherence and identify target groups for improvement of care with direct effect on caesarean section (CS) rates. METHOD: Eighteen obstetricians and midwives participated in an expert panel for systematic CS quality indicator development according to the RAND-modified Delphi method. A multi-center study was performed and medical charts of 1024 women with a CS and a stratified and weighted randomly selected group of 1036 women with a vaginal delivery were analysed. Quality indicator frequency and adherence were scored in 2060 women with a CS or vaginal delivery. RESULTS: The expert panel developed 16 indicators on planned CS and 11 indicators on unplanned CS. Indicator adherence was calculated, defined as the number of women in a specific obstetrical situation in which care was performed as recommended in both planned and unplanned CS settings. The most frequently occurring obstetrical situations with low indicator adherence were: 1) suspected fetal distress (frequency 17%, adherence 46%), 2) non-progressive labour (frequency 12%, CS performed too early in over 75%), 3) continuous support during labour (frequency 88%, adherence 37%) and 4) previous CS (frequency 12%), with adequate counselling in 15%. CONCLUSIONS: We identified four concrete target groups for improvement of obstetrical care, which can be used as a starting point to reduce CS rates worldwide.

Neurodevelopmental outcome of twins at two years of age according to the planned mode of delivery.

OBJECTIVES: To determine neurodevelopment at two years in twins. METHODS: At two years of age, all twins ≥32 weeks, delivered in our center and not randomized in the Twin Birth Study, underwent a neurodevelopment screen using the Ages and Stages Questionnaire (ASQ). Children with ≥1 abnormal ASQ domain score were evaluated by a pediatrician. Results were documented according to a planned cesarean section (PCS) or a planned vaginal delivery (PVD). RESULTS: An ASQ was obtained from 185 children (67%). No significant differences in percentages of abnormal scores were found between the PCS group and the PVD group or between twins A and B. Pediatric assessment revealed three children with a neurodevelopmental delay. Five other children were already under pediatric or general practitioner care for other reasons. One child with a congenital anomaly was born by a PCS, two twins A and five twins B were born in the PVD group. CONCLUSION: ASQ screening revealed no significant differences in abnormal neurodevelopment in twins at two years of age according to the mode of delivery. Pediatric assessment suggested an increased incidence for abnormal neurodevelopment in twins B born by PVD.

Clinical indicators associated with the mode of twin delivery: an analysis of 22,712 twin pairs.

OBJECTIVE: To identify clinical indicators associated with the planned and actual mode of delivery in women with a twin pregnancy. STUDY DESIGN: We performed a retrospective cohort study in women with a twin pregnancy who delivered at a gestational age of 32+0-41+0 weeks and days between 2000 and 2008 in the Netherlands. Data were obtained from a nationwide database. We identified maternal, pregnancy-related, fetal, neonatal and hospital-related indicators that were associated with planned cesarean section (CS) and, for women with planned vaginal delivery (VD), for intrapartum CS. The associations between indicators and mode of delivery were studied with uni- and multivariate logistic regression analyses. RESULTS: We included 22,712 women with a twin pregnancy, of whom 4,310 women (19.0%) had a planned CS. Of the 18,402 women who had a planned VD, 14,034 (76.3%) delivered vaginally, 3,545 (19.3%) had an intrapartum CS, while 823 (4.5%) delivered twin A vaginally and twin B by intrapartum CS. The clinical indicators for a planned CS and an intrapartum CS were comparable: non-cephalic position of both twins (aOR 25.32; 95% CI 22.50-28.50, and aOR 21.94; 95% CI 18.67-25.78, respectively), non-cephalic position of twin A only (aOR 21.67 95% CI 19.12-24.34, and aOR 13.71; 95% CI 11.75-16.00, respectively), previous CS (aOR 3.69; 95% CI 3.12-4.36, and aOR 7.00; 95% CI 5.77-8.49, respectively), nulliparity (aOR 1.51; 95% CI 1.32-1.72, and aOR 4.20; 95% CI 3.67-4.81, respectively), maternal age ≥41 years (aOR 3.00; 95% CI 2.14-4.22, and aOR 2.50; 95% CI 1.75-3.59, respectively), and pre-eclampsia (aOR 2.12; 95% CI 1.83-2.46, and aOR 1.34; 95% CI 1.16-1.56, respectively). CONCLUSION: Both planned and intrapartum CS in twins had comparable predictors: non-cephalic position of both twins or twin A only, previous CS, nulliparity, advanced maternal age, and pre-eclampsia.

The capacity of mid-pregnancy cervical length to predict preterm birth in low-risk women: a national cohort study.

INTRODUCTION: We investigated the predictive capacity of mid-trimester cervical length (CL) measurement for spontaneous and iatrogenic preterm birth. MATERIAL AND METHODS: We performed a prospective observational cohort study in nulliparous women and low-risk multiparous women with a singleton pregnancy between 16(+0) and 21(+6) weeks of gestation. We assessed the prognostic capacity of transvaginally measured mid-trimester CL for spontaneous and iatrogenic preterm birth (<37 weeks) using likelihood ratios (LR) and receiver-operating-characteristic analysis. We calculated numbers needed to screen to prevent one preterm birth assuming different treatment effects. Main outcome measures were preterm birth <32, <34 and <37 weeks. RESULTS: We studied 11,943 women, of whom 666 (5.6%) delivered preterm: 464 (3.9%) spontaneous and 202 (1.7%) iatrogenic. Mean CL was 44.1 mm (SD 7.8 mm). In nulliparous women, the LRs for spontaneous preterm birth varied between 27 (95% CI 7.7-95) for a CL ≤ 20 mm, and 2.0 (95% CI 1.6-2.5) for a CL between 30 and 35 mm. For low-risk multiparous women, these LRs were 37 (95% CI 7.5-182) and 1.5 (95% CI 0.97-2.2), respectively. Using a cut-off for CL ≤ 30 mm, 28 (6.0%) of 464 women with spontaneous preterm birth were identified. The number needed to screen to prevent one case of preterm birth was 618 in nulliparous women and 1417 for low-risk multiparous women (40% treatment effect, cut-off 30 mm). CONCLUSION: In women at low risk of preterm birth, CL predicts spontaneous preterm birth. However, its isolated use as a screening tool has limited value due to low sensitivity.

Dilemma in timing of delivery in a patient with an acute myocardial infarction.

Introduction. Acute myocardial infarction (AMI) in a pregnant woman is rare. When occurring, AMI is a major cause of maternal and neonatal death. By presenting the following case we describe the dilemma concerning the timing of delivery. Case. A 36-year-old, multiparous women, at 35 6/7 weeks of gestation, suffered from an AMI due to an acute blockage of the left anterior descending artery (LAD). This was treated by angiographic thrombosuction and biodegradable stent placement. Within 5 hours after this procedure, a cesarean section (CS) was performed because of a nonreassuring fetal condition. A healthy son with an Apgar score of 9/10 was born. The patient's postoperative course was complicated by a big wound hematoma, a hemoglobin drop, and heart failure. Discussion. In case of AMI during pregnancy, the cardiological management has absolute priority. The obstetrical management is not outlined. In a nonreassuring fetal condition, delivery is indicated after stabilization of the mother. However, delivery after recent AMI and angiography will bring new risks of cardiologic stress and bleeding complications. The limited literature available tends to an expectant obstetrical management, but this case emphasizes the difficulty of waiting in suspected fetal distress.

Epidural analgesia and operative delivery: a ten-year population-based cohort study in The Netherlands.

OBJECTIVE: To describe trends in the use of epidural analgesia (EA) and to evaluate the association of EA with operative deliveries. STUDY DESIGN: In this population-based, retrospective cohort study, women with an intention to deliver vaginally of a term, cephalic, singleton between 2000 and 2009 (n=1378458) were included. Main outcome measures were labor EA rates, unplanned caesarean section (CS), and instrumental vaginal delivery (IVD) including deliveries by either vacuum or forceps. Data were obtained from the Perinatal Registry of The Netherlands and logistic regression analyses were used. RESULTS: Among nulliparous, EA use almost tripled over the 10-year span (from 7.7% to 21.9%), while rates of CS and IVD did not change much (+2.8% and -3.3%, respectively). Among multiparous, EA use increased from 2.4% to 6.8%, while rates of CS and IVD changed slightly (+0.8% and -0.7%, respectively). Multivariable analysis showed a positive association of EA with CS, which weakened in ten years, from an adjusted OR of 2.35 (95% CI, 2.18 to 2.54) to 1.69 (95% CI, 1.60 to 1.79; p<0.001) in nulliparous, and from an adjusted OR of 3.17 (95% CI, 2.79 to 3.61) to 2.56 (95% CI, 2.34 to 2.81; p<0.001) in multiparous women. A weak inverse association between EA and IVD was found among nulliparous (adjusted OR, 0.76; 95% CI, 0.75 to 0.78), and a positive one among multiparous women (adjusted OR, 2.08; 95% CI, 2.00 to 2.16). Both associations grew slightly weaker over time. CONCLUSIONS: A near triplication of EA use in The Netherlands in ten years was accompanied by relatively stable rates of operative deliveries. The association between EA and operative delivery became weaker. This supports the idea that EA is not an important causal factor of operative deliveries.
