Background: Preterm birth is in quantity and in severity the most important topic in obstetric care in the developed world. Progestogens and cervical pessaries have been studied as potential preventive treatments with conflicting results. So far, no study has compared both treatments., Methods/design: The Quadruple P study aims to compare the efficacy of vaginal progesterone and cervical pessary in the prevention of adverse perinatal outcome associated with preterm birth in asymptomatic women with a short cervix, in singleton and multiple pregnancies separately. It is a nationwide open-label multicentre randomized clinical trial (RCT) with a superiority design and will be accompanied by an economic analysis. Pregnant women undergoing the routine anomaly scan will be offered cervical length measurement between 18 and 22 weeks in a singleton and at 16-22 weeks in a multiple pregnancy. Women with a short cervix, defined as less than, or equal to 35 mm in a singleton and less than 38 mm in a multiple pregnancy, will be invited to participate in the study. Eligible women will be randomly allocated to receive either progesterone or a cervical pessary. Following randomization, the silicone cervical pessary will be placed during vaginal examination or 200 mg progesterone capsules will be daily self-administered vaginally. Both interventions will be continued until 36 weeks gestation or until delivery, whichever comes first. Primary outcome will be composite adverse perinatal outcome of perinatal mortality and perinatal morbidity including bronchopulmonary dysplasia, intraventricular haemorrhage grade III and IV, periventricular leukomalacia higher than grade I, necrotizing enterocolitis higher than stage I, Retinopathy of prematurity (ROP) or culture proven sepsis. These outcomes will be measured up until 10 weeks after the expected due date. Secondary outcomes will be, among others, time to delivery, preterm birth rate before 28, 32, 34 and 37 weeks, admission to neonatal intensive care unit, maternal morbidity, maternal admission days for threatened preterm labour and costs., Discussion: This trial will provide evidence on whether vaginal progesterone or a cervical pessary is more effective in decreasing adverse perinatal outcome in both singletons and multiples., Trial Registration: Trial registration number: NTR 4414 . Date of registration January 29th 2014.

Objective: To assess the effect of red blood cell (RBC) transfusion on quality of life in acutely anaemic women after postpartum haemorrhage., Design: Randomised non-inferiority trial., Setting: Thirty-seven Dutch university and general hospitals., Population: Women with acute anaemia (haemoglobin 4.8-7.9 g/dl [3.0-4.9 mmol/l] 12-24 hours postpartum) without severe anaemic symptoms or severe comorbidities., Methods: Women were allocated to RBC transfusion or non-intervention., Main Outcome Measures: Primary outcome was physical fatigue 3 days postpartum (Multidimensional Fatigue Inventory, scale 4-20; 20 represents maximal fatigue). Non-inferiority was demonstrated if the physical fatigue difference between study arms was maximal 1.3. Secondary outcomes were health-related quality of life and physical complications. Health-related quality of life questionnaires were completed at five time-points until 6 weeks postpartum., Results: In all, 521 women were randomised to non-intervention (n = 262) or RBC transfusion (n = 259). Mean physical fatigue score at day 3 postpartum, adjusted for baseline and mode of delivery, was 0.8 lower in the RBC transfusion arm (95% confidence interval: 0.1-1.5, P = 0.02) and at 1 week postpartum was 1.06 lower (95% confidence interval: 0.3-1.8, P = 0.01). A median of two RBC units was transfused in the RBC transfusion arm. In the non-intervention arm, 33 women received RBC transfusion, mainly because of anaemic symptoms. Physical complications were comparable., Conclusions: Statistically, non-inferiority could not be demonstrated as the confidence interval crossed the non-inferiority boundary. Nevertheless, with only a small difference in physical fatigue and no differences in secondary outcomes, implementation of restrictive management seems clinically justified., (© 2014 Royal College of Obstetricians and Gynaecologists.)

Objective: To assess the economic consequences of labour induction with Foley catheter compared to prostaglandin E2 gel., Design: Economic evaluation alongside a randomised controlled trial., Setting: Obstetric departments of one university and 11 teaching hospitals in the Netherlands., Population: Women scheduled for labour induction with a singleton pregnancy in cephalic presentation at term, intact membranes and an unfavourable cervix; and without previous caesarean section., Methods: Cost-effectiveness analysis from a hospital perspective., Main Outcome Measures: We estimated direct medical costs associated with healthcare utilisation from randomisation to 6 weeks postpartum. For caesarean section rate, and maternal and neonatal morbidity we calculated the incremental cost-effectiveness ratios, which represent the costs to prevent one of these adverse outcomes., Results: Mean costs per woman in the Foley catheter group (n = 411) and in the prostaglandin E₂ gel group (n = 408), were €3297 versus €3075, respectively, with an average difference of €222 (95% confidence interval -€157 to €633). In the Foley catheter group we observed higher costs due to longer labour ward occupation and less cost related to induction material and neonatal admissions. Foley catheter induction showed a comparable caesarean section rate compared with prostaglandin induction, therefore the incremental cost-effectiveness ratio was not informative. Foley induction resulted in fewer neonatal admissions (incremental cost-effectiveness ratio €2708) and asphyxia/postpartum haemorrhage (incremental cost-effectiveness ratios €5257) compared with prostaglandin induction., Conclusions: Foley catheter and prostaglandin E2 labour induction generate comparable costs., (© 2013 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2013 RCOG.)

Objective: To compare group counselling to individual counselling with respect to the second trimester ultrasound., Design: A prospective cohort study at two hospitals., Method: At one hospital, 100 pregnant women were counselled on the risks and benefits of the second trimester ultrasound in groups of up to 15 patients. Shortly before the ultrasound they were asked to fill out a questionnaire. Results were compared to 100 women who were counselled individually at another hospital. The primary outcome was the level of informed choice whether or not to undergo the ultrasound, defined as sufficient knowledge and a value-consistent decision. The secondary outcome measures were level of understanding of the second trimester ultrasound and the degree of satisfaction with the counselling., Results: The resulting level of informed choice was 87.0% after group counselling compared to 79.4% after individual counselling (p = 0.47). The mean knowledge score was 8.8 for the women who attended group counselling; women who were individually counselled had a mean score of 7.4 (p < 0.001). Satisfaction with counselling was 7.0 for group counselling and 6.2 for individual counselling (p < 0.001)., Conclusion: Although there was no statistically significant difference in the level of informed choice, group counselling was associated with higher post-counselling knowledge and satisfaction scores. Group counselling should therefore be considered as an alternative counselling method.

Objective: To determine the incidence of maternal deaths attributable to meningitis in the Netherlands, and to assess clinical features and risk factors., Design: Confidential enquiry into the causes of maternal deaths., Setting: Nationwide in the Netherlands., Population: A total of 4 784 408 live births., Methods: Analysis of all maternal deaths due to meningitis in pregnancy and puerperium from 1983 up to and including 2007 reported to the Maternal Mortality Committee of the Dutch Society of Obstetrics and Gynaecology., Main Outcome Measures: Incidence, clinical features and risk factors., Results: Fifteen maternal deaths occurred due to meningitis, representing 4.4% of all maternal deaths. Twelve women (80%) presented with meningitis during pregnancy, 8 (66%) of them in the third trimester. Presenting symptoms were altered mental status (11; 73%), fever (9; 60%), nuchal rigidity (5; 33%) and headache (13; 87%). Nine women (60%) had otolaryngological infection at presentation or in the previous days or weeks. Twelve women (80%) underwent radiological examination, of which 5 (33%) showed distinct abnormalities. Cerebrospinal fluid (CSF) examination showed infected CSF in 8 (53%) women. In ten women (67%) Streptococcus pneumoniae was isolated. Substandard care was identified in 4 (27%) women., Conclusion: Pregnant or puerperal women presenting with classical symptoms of meningitis, particularly those with a history of otolaryngological infection or headache, should undergo thorough investigation and radiological and CSF examinations. Early diagnosis and immediate antibiotic treatment are imperative because of rapid deterioration in pregnant women. In case of doubt, the threshold for antibiotic treatment should be low and close monitoring is warranted., (© 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.)

Objective: To investigate the association between maternal intrapartum fever and ST-waveform changes of the fetal electrocardiogram., Design: Retrospective cohort study., Setting: Three academic and six non-academic teaching hospitals in the Netherlands., Population: Labouring women with a high-risk singleton pregnancy in cephalic position beyond 36 weeks of gestation., Methods: We studied 142 women with fever (≥38.0°C) during labour and 141 women with normal temperature who had been included in two previous studies. In both groups, we counted the number and type of ST-events and classified them as significant (intervention needed) or not significant, based on STAN(®) clinical guidelines., Main Outcome Measures: Number and type of ST-events., Results: Both univariable and multivariable regression analysis showed no association between the presence of maternal intrapartum fever and the number or type of ST-events., Conclusions: Maternal intrapartum fever is not associated with ST-segment changes of the fetal electrocardiogram. Interpretation of ST-changes in labouring women with fever should therefore not differ from other situations., (© 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.)

Objective: To evaluate whether correct adherence to clinical guidelines might have led to prevention of cases with adverse neonatal outcome., Design: Secondary analysis of cases with adverse outcome in a multicenter randomized clinical trial., Setting: Nine Dutch hospitals., Population: Pregnant women with a term singleton fetus in cephalic position., Methods: Data were obtained from a randomized trial that compared monitoring by STAN® (index group) with cardiotocography (control group). In both trial arms, three observers independently assessed the fetal surveillance results in all cases with adverse neonatal outcome, to determine whether an indication for intervention was present, based on current clinical guidelines., Main Outcome Measures: Adverse neonatal outcome cases fulfilled one or more of the following criteria: (i) metabolic acidosis in umbilical cord artery (pH < 7.05 and base deficit in extracellular fluid >12 mmol/L); (ii) umbilical cord artery pH < 7.00; (iii) perinatal death; and/or (iv) signs of moderate or severe hypoxic ischemic encephalopathy., Results: We studied 5681 women, of whom 61 (1.1%) had an adverse outcome (26 index; 35 control). In these women, the number of performed operative deliveries for fetal distress was 18 (69.2%) and 16 (45.7%), respectively. Reassessment of all 61 cases showed that there was a fetal indication to intervene in 23 (88.5%) and 19 (57.6%) cases, respectively. In 13 (50.0%) vs. 11 (33.3%) cases, respectively, this indication occurred more than 20 min before the time of delivery, meaning that these adverse outcomes could possibly have been prevented., Conclusions: In our trial, more strict adherence to clinical guidelines could have led to additional identification and prevention of adverse outcome., (© 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To predict instrumental vaginal delivery or caesarean section for suspected fetal distress or failure to progress., Design: Secondary analysis of a randomised trial., Setting: Three academic and six non-academic teaching hospitals in the Netherlands., Population: 5667 labouring women with a singleton term pregnancy in cephalic presentation., Methods: We developed multinomial prediction models to assess the risk of operative delivery using both antepartum (model 1) and antepartum plus intrapartum characteristics (model 2). The models were validated by bootstrapping techniques and adjusted for overfitting. Predictive performance was assessed by calibration and discrimination (area under the receiver operating characteristic), and easy-to-use nomograms were developed., Main Outcome Measures: Incidence of instrumental vaginal delivery or caesarean section for fetal distress or failure to progress with respect to a spontaneous vaginal delivery (reference)., Results:   375 (6.6%) and 212 (3.6%) women had an instrumental vaginal delivery or caesarean section due to fetal distress, and 433 (7.6%) and 571 (10.1%) due to failure to progress, respectively. Predictors were age, parity, previous caesarean section, diabetes, gestational age, gender, estimated birthweight (model 1) and induction of labour, oxytocin augmentation, intrapartum fever, prolonged rupture of membranes, meconium stained amniotic fluid, epidural anaesthesia, and use of ST-analysis (model 2). Both models showed excellent calibration and the receiver operating characteristics areas were 0.70-0.78 and 0.73-0.81, respectively., Conclusion:   In Dutch women with a singleton term pregnancy in cephalic presentation, antepartum and intrapartum characteristics can assist in the prediction of the need for an instrumental vaginal delivery or caesarean section for fetal distress or failure to progress., (© 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.)

Purpose: This systematic review aims to determine if there are evidence-based recommendations for the optimal mode of delivery for non-cephalic presenting first- and/or second twins. We investigated the impact of the mode of delivery on neonatal outcome for twin deliveries with (1) the first twin (twin A) in non-cephalic presentation, (2) the second (twin B) in non-cephalic presentation and (3) both twins in non-cephalic presentation., Methods: A computer-aided search of Medline, Embase, Cinahl and Cochrane databases was carried out and quality of the studies was assessed with the Cochrane Collaboration's tool for assessing risk of bias and the GRADE approach., Results: One high-quality clinical trial (60 twin pairs) and 16 moderate/low-quality observational studies (3,167 twin pairs) showed no difference in neonatal outcome between vaginal and caesarean delivery in twin A and/or B., Conclusion: Our results do not suggest benefit of caesarean over vaginal delivery for selected twin gestations with twin A and/or twin B in non-cephalic presentation. However, no final conclusion can be drawn due to the small sample sizes and statistic limitations of the included studies. Randomized studies with sufficient power are required to make a strong recommendation.

We sought to predict neonatal metabolic acidosis at birth using antepartum obstetric characteristics (model 1) and additional characteristics available during labor (model 2). In 5667 laboring women from a multicenter randomized trial that had a high-risk singleton pregnancy in cephalic presentation beyond 36 weeks of gestation, we predicted neonatal metabolic acidosis. Based on literature and clinical reasoning, we selected both antepartum characteristics and characteristics that became available during labor. After univariable analyses, the predictors of the multivariable models were identified by backward stepwise selection in a logistic regression analysis. Model performance was assessed by discrimination and calibration. To correct for potential overfitting, we (internally) validated the models with bootstrapping techniques. Of 5667 neonates born alive, 107 (1.9%) had metabolic acidosis. Antepartum predictors of metabolic acidosis were gestational age, nulliparity, previous cesarean delivery, and maternal diabetes. Additional intrapartum predictors were spontaneous onset of labor and meconium-stained amniotic fluid. Calibration and discrimination were acceptable for both models (c-statistic 0.64 and 0.66, respectively). In women with a high-risk singleton term pregnancy in cephalic presentation, we identified antepartum and intrapartum factors that predict neonatal metabolic acidosis at birth., (Copyright © 2012 by Thieme Medical Publishers, Inc.)

Objective: To evaluate the added value of the baseline T/QRS ratio to other known risk factors in predicting adverse outcome and interventions for suspected fetal distress., Design: Prospective cohort study., Setting: Three academic and six non-academic teaching hospitals in the Netherlands., Population: Laboring women with a high-risk cephalic singleton pregnancy beyond 36 weeks of gestation., Methods: We obtained STAN(®) recordings (ST-analysis, Neoventa, Sweden) from two previous studies. Three patient groups were defined: cases with adverse outcome, cases with emergency delivery because of suspected fetal distress without adverse outcome, and a reference group of uncomplicated cases. Baseline T/QRS ratios among the adverse outcome and intervention for suspected fetal distress cases were compared to those of the uncomplicated cases. The ability of baseline T/QRS to predict adverse outcome and suspected fetal distress was determined using a multivariable logistic model., Main Outcome Measures: The added value of the baseline T/QRS to other known risk factors in the prediction of adverse outcome and interventions for suspected fetal distress., Results: From 3462 recordings, 2459 were available for analysis. Median baseline T/QRS for uncomplicated cases, adverse outcome and interventions for suspected fetal distress were 0.12 (range 0.00-0.52), 0.12 (0.00-0.42) and 0.13 (0.00-0.39), respectively. There was no statistical difference between these groups. Multivariable analysis showed no added value of baseline T/QRS in the prediction of either adverse outcome or interventions for suspected fetal distress., Conclusion: Baseline T/QRS has no added value in the prediction of adverse neonatal outcome or interventions for suspected fetal distress., (© 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.)

Objective: To determine the incidence of maternal deaths attributable to vascular dissection and rupture in the Netherlands, and to assess clinical features, risk factors and the frequency of substandard care in the cases identified., Design: Confidential enquiry into the causes of maternal deaths., Setting: Nationwide in the Netherlands., Population: A total of 3,108,235 live births., Methods: Data analysis of all cases of maternal death from vascular dissection and rupture in the period 1993-2008. A literature review was also performed., Main Outcome Measures: Incidence, clinical features, risk factors and frequency of substandard care., Results: A total of 23 maternal deaths attributable to vascular dissection and rupture were reported. In most cases the location was aortic (n=13), followed by coronary (n=4) and splenic (n=3) arteries. Clinical features were various, but most women presented with sudden unexplainable pain. Risk factors were present in 14 cases (61%), with hypertension being most frequently reported in ten cases (43%). Substandard care was determined to have been received in 13 cases (56%), inadequate assessment of complaints and a delay in diagnosis being the most frequent problems identified., Conclusions: Vascular dissection and rupture in pregnancy, although rare, carry a high risk of maternal and fetal morbidity and mortality. Because of the rarity of this condition and its variety in presentation, diagnosis is easily missed. A high index of suspicion when a woman presents with suggestive complaints, leading to an early diagnosis, may improve the prognosis for the woman and her child., (© 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.)

Purpose: To determine the risk of uterine rupture for women undergoing trial of labour (TOL) with both a prior caesarean section (CS) and a vaginal delivery., Methods: A systematic literature search was performed using keywords for CS and uterine rupture. The results were critically appraised and the data from relevant and valid articles were extracted. Odds ratios were calculated and a pooled estimate was determined using the Mantel-Haenszel method., Results: Five studies were used for final analysis. Three studies showed a significant risk reduction for women with both a previous CS and a prior vaginal delivery (PVD) compared to women with a previous CS only, and two studies showed a trend towards risk reduction. The absolute risk of uterine rupture with a prior vaginal delivery varied from 0.17 to 0.46%. The overall odds ratio for PVD was 0.39 (95% CI 0.29-0.52, P < 0.00001)., Conclusion: Women with a history of both a CS and vaginal delivery are at decreased risk of uterine rupture when undergoing TOL compared with women who have only had a CS.

Objective: To assess the cost-effectiveness of addition of ST analysis of the fetal electrocardiogram (ECG; STAN) to cardiotocography (CTG) for fetal surveillance during labor compared with CTG only., Design: Cost-effectiveness analysis based on a randomized clinical trial on ST analysis of the fetal ECG., Setting: Obstetric departments of three academic and six general hospitals in The Netherlands. Population. Laboring women with a singleton high-risk pregnancy, a fetus in cephalic presentation, a gestational age >36 weeks and an indication for internal electronic fetal monitoring., Methods: A trial-based cost-effectiveness analysis was performed from a health-care provider perspective., Main Outcome Measures: Primary health outcome was the incidence of metabolic acidosis measured in the umbilical artery. Direct medical costs were estimated from start of labor to childbirth. Cost-effectiveness was expressed as costs to prevent one case of metabolic acidosis., Results: The incidence of metabolic acidosis was 0.7% in the ST-analysis group and 1.0% in the CTG-only group (relative risk 0.70; 95% confidence interval 0.38-1.28). Per delivery, the mean costs per patient of CTG plus ST analysis (n= 2 827) were €1,345 vs. €1,316 for CTG only (n= 2 840), with a mean difference of €29 (95% confidence interval -€9 to €77) until childbirth. The incremental costs of ST analysis to prevent one case of metabolic acidosis were €9 667., Conclusions: The additional costs of monitoring by ST analysis of the fetal ECG are very limited when compared with monitoring by CTG only and very low compared with the total costs of delivery., (© 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.)

Unlabelled: In a recently published randomized clinical trial on intrapartum fetal monitoring, fetal blood samples were obtained in 879 women. One serious complication of fetal blood sampling (FBS) was reported, a case in which physical examination of the neonate after delivery revealed clear fluid loss from the incision site. Four layers of the scalp appeared to be incised. The subarachnoid space was closed with 2 sutures, and antibiotics were started due to the risk of meningitis. The patient was discharged in good clinical condition. In this article, the case is presented and the literature reviewed. We found 12 articles reporting 37 cases of a complication due to FBS, none concerning leakage of cerebrospinal fluid. In conclusion, complications of FBS are rare but can be serious. Excessive fetal bleeding is most frequently reported and often associated with an underlying coagulopathy in the neonate., Target Audience: Obstetricians & Gynecologists, Family Physicians., Learning Objectives: After completion of this educational activity, the obstetrician/gynecologist should be better able to assess the chance of possible complications due to fetal blood sampling; select fetuses at risk for complications due to fetal blood sampling; and evaluate certain technical precautions when performing this procedure.

Background: Primary postpartum haemorrhage is an obstetrical emergency often causing acute anaemia that may require immediate red blood cell (RBC) transfusion. This anaemia results in symptoms such as fatigue, which may have major impact on the health-related quality of life. RBC transfusion is generally thought to alleviate these undesirable effects although it may cause transfusion reactions. Moreover, the postpartum haemoglobin level seems to influence fatigue only for a short period of time. At present, there are no strict transfusion criteria for this specific indication, resulting in a wide variation in postpartum policy of RBC transfusion in the Netherlands., Methods/design: The WOMB trial is a multicentre randomised non-inferiority trial. Women with acute anaemia due to postpartum haemorrhage, 12-24 hours after delivery and not initially treated with RBC transfusion, are eligible for randomisation. Patients with severe physical complaints are excluded. Patients are randomised for either RBC transfusion or expectant management. Health related quality of life (HRQoL) will be assessed at inclusion, at three days and one, three and six weeks postpartum with three validated measures (Multi-dimensional Fatigue Inventory, ShortForm-36, EuroQol-5D). Primary outcome of the study is physical fatigue three days postpartum. Secondary outcome measures are general and mental fatigue scores and generic health related quality of life scores, the number of RBC transfusions, length of hospital stay, complications and health-care costs. The primary analysis will be by intention-to-treat. The various longitudinal scores will be evaluated using Repeated Measurements ANOVA. A costs benefit analysis will also be performed. The power calculation is based on the exclusion of a difference in means of 1.3 points or greater in favour of RBC transfusion arm regarding physical fatigue subscale. With missing data not exceeding 20%, 250 patients per arm have to be randomised (one-sided alpha = 0.025, power = 80%)., Discussion: This study will provide evidence for a guideline regarding RBC transfusion in the postpartum patient suffering from acute anaemia. Equivalence in fatigue score, remaining HRQoL scores and physical complications between both groups is assumed, in which case an expectant management would be preferred to minimise transfusion reactions and costs.

Objective: To assess causes, trends, and substandard care in indirect maternal mortality in the Netherlands., Design: Confidential enquiry into causes of maternal death., Setting: Nationwide in the Netherlands., Population: A total of 2,557,208 live births., Methods: Data analysis of indirect maternal deaths in the period 1993-2005., Main Outcome Measures: Indirect maternal mortality., Results: Of the study subjects, 97 were classified as indirect deaths, representing a maternal mortality ratio of 3.3/100,000 live births, a significant increase compared to the preceding enquiry in the period 1983-1992 (MMR 2.4, OR 1.5, 95%CI 1.0-2.1). The percentage of cases not directly reported to the Maternal Mortality Committee decreased from 15 to 5%. Cardiovascular disorders were the leading cause of indirect maternal mortality, followed by cerebrovascular disorders. Vascular dissection (n = 19) was the most frequent specified cause of death. Risk factors were advanced maternal age, non-indigenous origin (Surinam and Dutch Antilles), and medical health risks before pregnancy. Substandard care was present in 35%, mainly being misjudgment of the severity of the condition and delay in initiating therapy., Conclusion: The rise of mortality due to indirect causes is considered a reflection of the change in risk profile of women of childbearing age and the result of demographic alterations concerning ethnicity and maternal age. The identification of high risk groups, preferably by programs of preconception care, should lead to improved care for these women, with a multidisciplinary approach when needed.

Objective: To assess causes, trends and substandard care factors in maternal mortality in the Netherlands. Design Confidential enquiry into the causes of maternal mortality., Setting: Nationwide in the Netherlands., Population: 2,557,208 live births., Methods: Data analysis of all maternal deaths in the period 1993-2005., Main Outcome Measures: Maternal mortality., Results: The overall maternal mortality ratio was 12.1 per 100 000 live births, which was a statistically significant rise compared with the maternal mortality ratio of 9.7 in the period 1983-1992 (OR 1.2, 95% CI 1.0-1.5). The most frequent direct causes were (pre-)eclampsia, thromboembolism, sudden death in pregnancy, sepsis, obstetric haemorrhage and amniotic fluid embolism. The number of indirect deaths also increased, mainly caused by an increase in cardiovascular disorders (OR 2.5, 95% CI 1.4-4.6). Women younger than 20 years and older than 45 years, those with high parity or from nonwestern immigrant populations were at higher risk. Most substandard care was found in women with pre-eclampsia (91%) and in immigrant populations (62%)., Conclusions: Maternal mortality in the Netherlands has increased since 1983-1992. Pre-eclampsia remains the number one cause. Groups at higher risk for complications during pregnancy should be better identified early in pregnancy or before conception, in order to receive preconception advice and more frequent antenatal visits. There is an urgent need for the better education of women and professionals concerning the danger signs, and for the training of professionals in order to improve maternal health care.

Objective: To assess incidence and risk factors of maternal mortality and severe morbidity from sepsis in the Netherlands., Design: A nationwide confidential enquiry into maternal mortality from 1993 to 2006 and severe maternal morbidity from 2004 to 2006., Setting: All 98 Dutch maternity units in the Netherlands., Population: All pregnant women in the Netherlands from 1993 to 2006., Methods: All reported cases of maternal death from sepsis during 1993-2006 were reported to the Maternal Mortality Committee. Cases of severe maternal morbidity from sepsis from 2004 to 2006 were collected in a nationwide design. Main outcome measures. Incidence, case fatality rates, and possible risk factors., Results: The maternal mortality ratio from direct maternal mortality from sepsis was 0.73 per 100,000 live births (20/2,742,265). The incidence of severe maternal morbidity from sepsis was 21 per 100,000 deliveries (78/371,021), of which 79% was admitted to the intensive care unit. High age, multiple pregnancies, and the use of artificial reproduction techniques were significant risk factors for developing sepsis in univariate analysis. The overall case fatality rate for sepsis during 2004-2006 was 7.7% (6/78). Group A streptococcal infection was in 42.9% (9/21), the cause of direct maternal mortality from sepsis (1993-2006). In 31.8% (14/44), Group A streptococcal infection was the cause of obstetric morbidity from sepsis (2004-2006)., Conclusions: With a case fatality rate of 7.7%, sepsis is a life threatening condition for women during pregnancy, childbirth, and puerperium.

Background: The percentage of women giving birth after the age of 35 increased in many western countries. The number of women remaining childless also increased, mostly due to aging oocytes. The method of oocyte donation offers the possibility for infertile older women to become pregnant. Gestation after oocyte-donation-IVF, however, is not without risks for the mother, especially at advanced age., Case Presentation: An infertile woman went abroad for oocyte-donation-IVF, since this treatment is not offered in The Netherlands after the age of 45. The first oocyte donation treatment resulted in multiple gestation, but was ended by induced abortion: the woman could not cope with the idea of being pregnant with twins. During the second pregnancy after oocyte donation, at the age of 50, she was mentally more stable. The pregnancy, again a multiple gestation, was uneventful until delivery. Immediately after delivery the woman had hypertension with nausea and vomiting. A few hours later she had an eclamptic fit. HELLP-syndrome was diagnosed. She died due to cerebral haemorrhage., Conclusion: In The Netherlands, the age limit for women receiving donor oocytes is 45 years and commercial oocyte donation is forbidden by law. In other countries there is no age limit, the reason why some women are going abroad to receive the treatment of their choice. Advanced age, IVF and twin pregnancy are all risk factors for pre-eclampsia, the leading cause of maternal death in The Netherlands.Patient autonomy is an important ethical principle, but doctors are also bound to the principle of 'not doing harm', and do have the right to refuse medical treatment such as IVF-treatment. The discussion whether women above 50 should have children is still not closed. If the decision is made to offer this treatment to a woman at advanced age, the doctor should counsel her intensively about the risks before treatment is started.

Objectives: To review the standard of care in cases of maternal mortality due to hypertensive diseases in pregnancy and to make recommendations for its improvement., Design: Care given to women with hypertensive disease in pregnancy was audited and substandard care factors identified., Setting: Confidential enquiry by the Dutch Maternal Mortality Committee (MMC) from the Netherlands Society of Obstetrics and Gynaecology., Population: All maternal deaths reported to the MMC due to hypertensive disease in pregnancy in the Netherlands during the years 2000-04., Methods: Assessment for substandard care factors using a checklist based on the Dutch guideline of 'Hypertensive Disorders in Pregnancy'., Main Outcome Measures: Substandard care in cases of maternal mortality due to hypertensive diseases in pregnancy., Results: A total of 27 cases of maternal death due to hypertensive disease in pregnancy were reported to the committee in the study period. In 26 cases (96%), substandard care factors were present, of which in 17 cases (63%), these were for more than five different items. In community midwifery care, the most frequent substandard care factor was no testing for proteinuria when clearly indicated (41%). In hospital care, the most frequent substandard care was related to insufficient diagnostic testing when indicated (41%), insufficient management of hypertension by obstetricians (85%), no use or inadequate use of magnesium sulphate (67%), inadequate stabilisation before transport to tertiary care centres and/or delivery (52%) and failure to consider timely delivery (44%)., Conclusions: Education of pregnant women concerning danger signs of hypertensive disease should be improved. Training of midwives and obstetricians should be improved in the following areas: performing basic diagnostic tests, adequate management of hypertension and eclampsia, with more attention to treatment of systolic blood pressure. This training should be guided by clear local protocols. Delivery should not be delayed in serious cases of hypertensive disease in pregnancy, not only after 32-34 weeks but also in early-onset pre-eclampsia as maternal risks often outweigh possible fetal benefits of temporising management.

Background: Cardiotocography (CTG) is worldwide the method for fetal surveillance during labour. However, CTG alone shows many false positive test results and without fetal blood sampling (FBS), it results in an increase in operative deliveries without improvement of fetal outcome. FBS requires additional expertise, is invasive and has often to be repeated during labour. Two clinical trials have shown that a combination of CTG and ST-analysis of the fetal electrocardiogram (ECG) reduces the rates of metabolic acidosis and instrumental delivery. However, in both trials FBS was still performed in the ST-analysis arm, and it is therefore still unknown if the observed results were indeed due to the ST-analysis or to the use of FBS in combination with ST-analysis., Methods/design: We aim to evaluate the effectiveness of non-invasive monitoring (CTG + ST-analysis) as compared to normal care (CTG + FBS), in a multicentre randomised clinical trial setting. Secondary aims are: 1) to judge whether ST-analysis of fetal electrocardiogram can significantly decrease frequency of performance of FBS or even replace it; 2) perform a cost analysis to establish the economic impact of the two treatment options. Women in labour with a gestational age > or = 36 weeks and an indication for CTG-monitoring can be included in the trial. Eligible women will be randomised for fetal surveillance with CTG and, if necessary, FBS or CTG combined with ST-analysis of the fetal ECG. The primary outcome of the study is the incidence of serious metabolic acidosis (defined as pH < 7.05 and Bdecf > 12 mmol/L in the umbilical cord artery). Secondary outcome measures are: instrumental delivery, neonatal outcome (Apgar score, admission to a neonatal ward), incidence of performance of FBS in both arms and cost-effectiveness of both monitoring strategies across hospitals. The analysis will follow the intention to treat principle. The incidence of metabolic acidosis will be compared across both groups. Assuming a reduction of metabolic acidosis from 3.5% to 2.1 %, using a two-sided test with an alpha of 0.05 and a power of 0.80, in favour of CTG plus ST-analysis, about 5100 women have to be randomised. Furthermore, the cost-effectiveness of CTG and ST-analysis as compared to CTG and FBS will be studied., Discussion: This study will provide data about the use of intrapartum ST-analysis with a strict protocol for performance of FBS to limit its incidence. We aim to clarify to what extent intrapartum ST-analysis can be used without the performance of FBS and in which cases FBS is still needed., Trial Registration Number: ISRCTN95732366.

Background and Methods: The cesarean section rate for term singleton breech babies in the Netherlands rose from 57 to 81% after the Term Breech Trial in 2000. The Dutch Maternal Mortality Committee registered and evaluated maternal mortality due to elective cesarean section for breech., Results: Four maternal deaths after elective cesarean section for breech presentation, from 2000 to 2002 inclusive, were registered, 7% of total direct maternal mortality in that period. Two women died due to massive pulmonary embolism, both were obese, and thromboprophylaxis was not adjusted to their weight. The other two women died from sepsis, one had not receive perioperative prophylactic antibiotics. The case fatality rate for elective cesarean section for breech presentation was 0.47/1,000 operations. No death after emergency cesarean section for breech presentation was registered at the committee., Conclusions: Elective cesarean section does not guarantee the improved outcome of the child, but may increase risks for the mother, compared to vaginal delivery.

As part of the Confidential Enquiry into the Causes of Maternal Deaths in The Netherlands, substandard care was assessed in immigrant versus indigenous maternal deaths. Except for substandard care related to the women's and relatives' decisions, substandard care factors were hypothesised to occur in similar frequency among both groups of women. The results, however, indicate that substandard care factors related to all aspects of care were disproportionately more frequent in immigrant women. More research into the interpretation of these worrying data is needed.

In three pregnant women, lethal anomalies of the fetus were diagnosed ultrasonographically in the second trimester. These women decided to continue their pregnancies for different reasons. One woman strongly regretted her decision to abort a previous pregnancy. The second hoped that the doctors were mistaken on the prognosis. The third woman was afraid of medical interventions. In case of lethal anomalies of the fetus, doctors should advise their patients to consider both options: termination as well as continuation of their pregnancy. Irrespective of the women's choice, doctors ought to be committed to support the pregnant women in such a troublesome situation.

Objective: To compare a one-step (rapid) application of negative pressure (vacuum) with conventional stepwise application for ventouse extraction following a prolonged second stage of labour., Design: Randomised controlled study., Setting: Teaching Hospital., Participants: Forty-seven women were randomised to the rapid vacuum group and 47 to the stepwise group., Main Outcome Measures: Duration of ventouse procedure, effectiveness of methods of application, morbidity of mother and infant., Results: There was no significant difference in frequency of detachment of the cup after rapid or stepwise application of vacuum. A reduction in mean duration of the ventouse procedure of 6 min was realised without significant difference in maternal or neonatal morbidity., Conclusion: Rapid application of vacuum significantly reduces the duration of a ventouse extraction procedure without compromise to efficiency and safety.

In an 86-year-old woman a neglected pessary and extreme coprostasis gave rise to anuria, urosepsis and bilateral ureteropelvic dilatation with an empty bladder. This seems to be the first reported case of its kind.

Maternal mortality rates in developed countries have declined steeply during the last 50 years. The introduction of sulphonamides and blood transfusion techniques contributed much to lowering maternal mortality rates. The maternal mortality rate in The Netherlands in 1983-1988 was 8.8/100,000 livebirths. In 57% substandard care factors could be identified. This suggests that further improvement in preventing maternal mortality is possible. Maternal mortality rates in developing countries are still unacceptably high as a result of high fertility and a high risk of dying each time a woman becomes pregnant. Complications of illegal abortion are responsible for 25-50% of maternal deaths. Safe contraception could probably result in an important reduction in the number of maternal deaths, but also the provision of accessible maternal health services is essential to reduce maternal mortality in developing countries.

We observed a patient who had a severe anaphylactic reaction 1 hour after HSG. Allergic symptoms recurred several hours after antiallergic therapy was stopped. The initial complaints of pain and vomiting could have been due to peritoneal irritation or alternatively to an early anaphylactic reaction. Patients who are at risk should be carefully evaluated before performing HSG. These patients and those with complaints after HSG should stay under observation for 1 or 2 hours after HSG.

Three cases of severe postpartum haemorrhage due to a laceration in the endocervical canal at the level of the internal os are described. The cause of the laceration differed in all cases. Whenever postpartum haemorrhage occurs the possibility of a laceration in the internal os must be considered.
