RESUMO

INTRODUCTION: Adjunctive technologies to cardiotocography intend to increase the specificity of the diagnosis of fetal hypoxia. If correctly diagnosed, time to delivery could affect neonatal outcome. In the present study, we aimed to investigate the effect of time from when fetal distress is indicated by a high fetal blood sample (FBS) lactate concentration to operative delivery on the risk of adverse neonatal outcomes. MATERIAL AND METHODS: We conducted a prospective observational study. Deliveries with a singleton fetus in cephalic presentation at 36+0 weeks of gestation or later were included. Adverse neonatal outcomes, related to decision-to-delivery interval (DDI), were investigated in operative deliveries indicated by an FBS lactate concentration of at least 4.8 mmol/L. We applied logistic regression to estimate crude and adjusted odds ratios (aOR) of various adverse neonatal outcomes, with associated 95% confidence intervals (CI), for a DDI exceeding 20 minutes, compared with a DDI of 20 minutes or less. CLINICALTRIALS: gov Identifier: NCT04779294. RESULTS: The main analysis included 228 women with an operative delivery indicated by an FBS lactate concentration of 4.8 mmol/L or greater. The risk of all adverse neonatal outcomes was significantly increased for both DDI groups compared with the reference group (deliveries with an FBS lactate below 4.2 mmol/L within 60 minutes before delivery). In operative deliveries indicated by an FBS lactate concentration of 4.8 mmol/L or more, there was a significantly increased risk of a 5-minute Apgar score less than 7 if the DDI exceeded 20 minutes, compared with a DDI of 20 minutes or less (aOR 8.1, 95% CI 1.1-60.9). We found no statistically significant effect on other short-term outcomes for deliveries with DDI longer than 20 minutes, compared with those with DDI of 20 minutes or less (pH ≤7.10: aOR 2.0, 95% CI 0.5-8.4; transfer to the neonatal intensive care unit: aOR 1.1, 95% CI 0.4-3.5). CONCLUSIONS: After a high FBS lactate measurement, the increased risk of adverse neonatal outcome is further augmented if the DDI exceeds 20 minutes. These findings give support to current Norwegian guidelines for intervention in cases of fetal distress.

RESUMO

BACKGROUND: A negative childbirth experience has short- and long-term consequences for both mother and child. This study aimed to investigate the association between intrapartum pudendal nerve block (PNB) analgesia and childbirth experience. METHODS: Primiparous women with a singleton cephalic vaginal live births at term at Oslo University Hospital from January 1, 2017, to June 1, 2019, were eligible for inclusion. The main outcome was total score on a childbirth experience questionnaire (range 1.0-4.0, higher score indicates better childbirth experience). An absolute risk difference of 0.10 was considered clinically relevant. Propensity score matching was used to adjust for differences in baseline characteristics between women with and without PNB. The analyses were stratified by spontaneous vs instrumental birth. Subanalyses of the questionnaire's domains (own capacity, professional support, perceived safety, and participation) were performed. RESULTS: Of 979 participating women, mean age was 32 years. Childbirth experience did not differ between women with and without PNB, either in spontaneous (absolute risk difference of the mean: -0.05, P value 0.36) or in instrumental birth (absolute risk difference of the mean: 0.03, P value 0.61). There were no statistically significant differences between PNB group scores for the separate domains. CONCLUSIONS: Women's childbirth experiences did not differ between birthing people with or without PNB, either in spontaneous or in instrumental births. The clinical implications of our study should be interpreted in light of the pain-relieving effects of PNB.PNB should be provided on clinical indication, including for individuals with severe labor pain.

RESUMO

Objectives: Gestational diabetes mellitus (GDM) is an increasing problem among pregnant women globally and is associated with short- and long-term consequences for both mother and newborn. The aim of this study was to investigate knowledge of GDM among a multi-ethnic pregnant population at first consultation for GDM in the Oslo region in Norway.Design: We conducted a cross-sectional study using baseline data from a randomised controlled study performed at five diabetic outpatient clinics (DOC) in the Oslo region. Pregnant women diagnosed with GDM following an Oral Glucose Tolerance test (OGTT) with a 2-hours blood glucose level of ≥ 9 mmol/l were included. Women filled out a questionnaire on an electronic tablet at the study entry, and additional data were collected through a recruiting form. Descriptive statistics were performed and associations were investigated using Chi-square test and multiple logistic regression analysis.Results: Of 238 women included in the study, 108 (45.4%) were native Norwegian speakers and 130 (54.6%) were non-native Norwegian speakers. 39.5% of the non-native Norwegian speakers were Asian, 22.5% were African, and 15.5% were from Eastern European Countries. Non-native Norwegian speakers were significantly more likely to have poor knowledge of GDM compared to native Norwegian speakers, adjusted OR = 4.5, 95% CI 1.61-12.5. Sensitivity analyses showed this was not due to poor language skills.Conclusions: Ethnic background was associated with the level of knowledge of GDM. Health professionals should be aware of the various knowledge levels concerning GDM and tailor their information towards women's knowledge. Linguistically- and culturally adapted information regarding GDM may improve knowledge gaps among women with immigrant backgrounds.

RESUMO

INTRODUCTION AND HYPOTHESIS: Pudendal nerve block analgesia (PNB) is used as pain relief in the final stage of childbirth. We hypothesized that PNB is associated with higher rates of postpartum urinary retention. METHODS: We performed a cohort study among primiparous women with a singleton, cephalic vaginal birth at Oslo University Hospital, Norway. Women receiving PNB were included in the exposed group, while the subsequent woman giving birth without PNB was included in the unexposed group. We compared the likelihood of postpartum urinary retention, defined as catheterization within 3 h after birth. Logistic regression analysis stratified by mode of delivery was performed adjusting for epidural analgesia, episiotomy and birth unit. RESULTS: Of the 1007 included women, 499 were exposed to PNB and 508 were unexposed. In adjusted analyses, women exposed to PNB did not differ in likelihood of postpartum urinary retention compared to women unexposed to PNB in either spontaneous (odds ratio[OR]: 0.82, 95% confidence interval [CI] 0.55-1.22) or instrumental (OR 1.45, 95% CI 0.89-2.39) births. Furthermore, no differences between the groups were observed with excessive residual urine volume or catheterization after > 3 h. CONCLUSIONS: PNB was associated with neither risk of postpartum urinary retention nor excessive residual urine volume and is therefore unlikely to hamper future bladder function.

RESUMO

BACKGROUND: The provision of epidural analgesia during labor is ideally a shared decision between the woman and her health care provider. However, immigrant characteristics such as maternal birthplace could affect decision-making and thus access to pain relief. We aimed to assess disparities in the provision of epidural analgesia in planned vaginal birth according to maternal region of birth. METHODS: We performed a nation-wide register study of 842,496 live-born singleton deliveries in Norway between 2000 and 2015. Maternal birthplace was categorized according to the Global Burden of Disease framework. The provision of epidural analgesia was compared in regression models stratified by parity and mode of delivery. RESULTS: Compared to native-born women, primiparous women from Latin America/Caribbean countries with an instrumental vaginal delivery were most likely to be provided epidural analgesia (OR 2.12, 95%CI 1.69-2.66), whilst multiparous women from Sub-Saharan Africa with a spontaneous vaginal delivery were least likely to be provided epidural analgesia (OR 0.42, 95% C 0.39-0.44). Longer residence time was associated with a higher likelihood of being provided analgesia, whereas effects of maternal education varied by Global Burden of Disease group. CONCLUSIONS: Disparities in the likelihood of being provided epidural analgesia were observed by maternal birthplace. Further studies are needed to consider whether the identified disparities represent women's own preferences or if they are the result of heterogeneous access to analgesia during labor.

RESUMO

BACKGROUND: In high-income countries, the incidence of severe postpartum hemorrhage (PPH) has increased. This has important public health relevance because severe PPH is a leading cause of major maternal morbidity. However, few studies have identified risk factors for severe PPH within a contemporary obstetric cohort. METHODS: We performed a case-control study to identify risk factors for severe PPH among a cohort of women who delivered at one of three hospitals in Norway between 2008 and 2011. A case (severe PPH) was classified by an estimated blood loss ≥1500 mL or the need for blood transfusion for excessive postpartum bleeding. Using logistic regression, we applied a pragmatic strategy to identify independent risk factors for severe PPH. RESULTS: Among a total of 43,105 deliveries occurring between 2008 and 2011, we identified 1064 cases and 2059 random controls. The frequency of severe PPH was 2.5% (95% confidence interval (CI): 2.32-2.62). The most common etiologies for severe PPH were uterine atony (60%) and placental complications (36%). The strongest risk factors were a history of severe PPH (adjusted OR (aOR) = 8.97, 95% CI: 5.25-15.33), anticoagulant medication (aOR = 4.79, 95% CI: 2.72-8.41), anemia at booking (aOR = 4.27, 95% CI: 2.79-6.54), severe pre-eclampsia or HELLP syndrome (aOR = 3.03, 95% CI: 1.74-5.27), uterine fibromas (aOR = 2.71, 95% CI: 1.69-4.35), multiple pregnancy (aOR = 2.11, 95% CI: 1.39-3.22) and assisted reproductive technologies (aOR = 1.88, 95% CI: 1.33-2.65). CONCLUSIONS: Based on our findings, women with a history of severe PPH are at highest risk of severe PPH. As well as other established clinical risk factors for PPH, a history of severe PPH should be included as a risk factor in the development and validation of prediction models for PPH.

RESUMO

BACKGROUND: The procoagulant state in cancer increases the thrombotic risk, but also supports tumor progression. To investigate the molecular mechanisms controlling cancer and hemostasis, we conducted a case-control study of genotypic and phenotypic variables of the tissue factor (TF) pathway of coagulation in breast cancer. METHODS: 366 breast cancer patients and 307 controls were genotyped for SNPs (n = 41) in the F2, F3 (TF), F5, F7, F10, TFPI and EPCR genes, and assayed for plasma coagulation markers (thrombin generation, activated protein C (APC) resistance, D-dimer, antithrombin, protein C, protein S, and TF pathway inhibitor (TFPI)). Associations with breast cancer were evaluated using logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CIs), or the chi-square test. RESULTS: Four SNPs in F5 (rs12120605, rs6427202, rs9332542 and rs6427199), one in F10 (rs3093261), and one in EPCR (rs2069948) were associated with breast cancer. EPCR rs2069948 was associated with estrogen receptor (ER) and progesterone receptor (PR) positivity, while the SNPs in F5 appeared to follow hormone receptor negative and triple negative patients. The prothrombotic polymorphisms factor V Leiden (rs6025) and prothrombin G20210A (rs1799963) were not associated with breast cancer. High APC resistance was associated with breast cancer in both factor V Leiden non-carriers (OR 6.5, 95% CI 4.1-10.4) and carriers (OR 38.3, 95% CI 6.2-236.6). The thrombin parameters short lag times (OR 5.8, 95% CI 3.7-9.2), short times to peak thrombin (OR 7.1, 95% CI 4.4-11.3), and high thrombin peak (OR 6.1, 95% CI 3.9-9.5) predicted presence of breast cancer, and high D-dimer also associated with breast cancer (OR 2.0, 95% CI 1.3-3.3). Among the coagulation inhibitors, low levels of antithrombin associated with breast cancer (OR 5.7, 95% CI 3.6-9.0). The increased coagulability was not explained by the breast cancer associated SNPs, and was unaffected by ER, PR and triple negative status. CONCLUSIONS: A procoagulant phenotype was found in the breast cancer patients. Novel associations with SNPs in F5, F10 and EPCR to breast cancer susceptibility were demonstrated, and the SNPs in F5 were confined to hormone receptor negative and triple negative patients. The study supports the importance of developing new therapeutic strategies targeting coagulation processes in cancer.

RESUMO

BACKGROUND: Norway has low maternal mortality, but such deaths are underreported even in high-income countries. Our goal was to identify the exact number of maternal deaths, the causes of death and the potential for improvement through medical care in Norway. MATERIAL AND METHOD: We traced maternal deaths in the period from 1 January 2005 to 31 December 2009 by linking the Medical Birth Registry and the Cause of Death Registry, supplemented with data from maternity clinics. We identified the cause of death and the lessons that could be learned by a meticulous review of each case. RESULTS: We found 26 maternal deaths during the period, 14 of which were due to direct causes and 12 to indirect causes. The maternal mortality ratio was 8.7/100,000 live births. Fourteen of the deaths were registered in official statistics. Of the 12 deaths that were not included in the statistics, 11 were found through matching the registers and one had been reported directly by the hospital. The most common causes of death were hypertensive disorders during pregnancy (n = 6), thromboembolism (n = 4) and mental illness (n = 4). None of the deaths due to thromboembolism appeared in official statistics. The same applied to nine of the 12 indirect maternal deaths. We found a potential for improved medical care in 14 of 26 cases. Half of these were deaths due to hypertensive disorders during pregnancy or thromboembolism. INTERPRETATION: Maternal death was considerably underreported in Norwegian official statistics during the period studied. Greater attention should be given to better blood-pressure treatment, stabilisation and timely delivery in the case of hypertension during pregnancy, and to screening for possible pulmonary embolism. The same applies to mental illness and internal medical disorders in pregnant women.

RESUMO

OBJECTIVE: To investigate risk factors for stillbirths by cause, using the Causes of Death and Associated Conditions (CODAC) classification system for perinatal deaths. DESIGN: Case-control study. SETTING: Two university hospitals in Oslo, Norway, January 1990 through December 2003. SAMPLE: Women with stillbirth after 22 gestational weeks (n = 377) and controls with live births (n = 1 215), and a subsample of 105 cases and 262 controls. METHODS: Socio-demographic, clinical and thrombophilic risk factors for stillbirths were assessed by cause of death in univariate and multivariable logistic regression analyses. Stillbirths were classified according to CODAC based on information from medical records and validated placenta histology. MAIN OUTCOME MEASURES: Causes of stillbirths in percentages, prevalence, odds ratios and adjusted odds ratios for potential risk factors. RESULTS: Approximately half of the women (n = 190) had placental and 19.4% (n = 73) unknown cause of stillbirth. Placental-associated conditions were registered in 18% (n = 68) of cases with a non-placental or an unknown cause. Smoking and small-for-gestational age were more prevalent in all causal groups, compared with controls, whereas twin pregnancy, hypertension and diabetes were more prevalent only among women with placental and unknown causes of stillbirth. The F2rs179963 polymorphism and combined thrombophilia were significant risk factors for stillbirth with placental causes and antiphospholipid antibodies for stillbirth with non-placental causes. CONCLUSIONS: Two-thirds of all stillbirths (68%) were caused by or associated with placental pathology. Risk factors differed somewhat according to cause, apart from smoking and small-for-gestational age, which were significant risk factors across the causal groups.

RESUMO

Importance: Fetal death during labor at term is a complication that is rarely studied in high-income countries. There is a need for large population-based studies to examine the rate of term intrapartum stillbirth in high-income countries and the factors associated with its occurrence. Objective: To evaluate trends in term intrapartum stillbirth over time and to investigate the association between the trends and term intrapartum stillbirth risk factors from 1999 to 2018 in Norway. Design, Setting, and Participants: This cohort study used data from the Medical Birth Registry of Norway from 1999 to 2018 to examine rates of term intrapartum stillbirth and risk factors associated with this event. A population of 1 021 268 term singleton pregnancies without congenital anomalies or antepartum stillbirths was included in analyses, which were performed from September 2022 to February 2023. Exposure: The main exposure variable was time, which was divided into four 5-year periods: 1999 to 2003, 2004 to 2008, 2009 to 2013, and 2014 to 2018. Main Outcomes and Measures: The primary study outcome was term intrapartum stillbirth. Risk ratios were calculated, and multivariable logistic regression analyses were conducted to identify factors associated with secular trends of term intrapartum stillbirth. Results: The study population consisted of 1 021 268 term singleton births (maternal mean [SD] age, 29.72 [5.01] years; mean [SD] gestational age, 39.69 [1.27] weeks). During the study period, there were 95 term intrapartum stillbirths (0.09 per 1000 births). Maternal age, the proportion of individuals born in a country other than Norway, and the prevalence of gestational diabetes, labor induction, operative vaginal delivery, and previous cesarean delivery increased over the course of the study period. Conversely, the prevalence of infants large for gestational age, hypertensive disorder in pregnancy, and spontaneous vaginal delivery and the proportion of individuals who smoked decreased. The term intrapartum stillbirth rate decreased by 87% (95% CI, 68%-95%) from 0.15 per 1000 births in 1999 to 2008 to 0.02 per 1000 births in 2014 to 2018. Three in 4 term intrapartum stillbirths (70 of 95) occurred during intrapartum operative deliveries. The increased prevalence of older maternal age and obstetric risk factors were not associated with the variation in intrapartum stillbirth rates among the time periods. The prevalence of term intrapartum stillbirth was higher for individuals who gave birth in maternity units with fewer than 3000 annual births (adjusted odds ratio, 1.67; 95% CI, 1.07-2.61) than for those who gave birth in units with 3000 or more annual births. Conclusions and Relevance: Findings of this study suggest that, despite increases in maternal and obstetric risk factors, term intrapartum stillbirth rates substantially decreased during the study period. Reasons for this decrease may be due to improvements in intrapartum care.

RESUMO

BACKGROUND: Group B Streptococcus (GBS) is a major cause of serious neonatal infection but its role in maternal morbidity has received little investigation. The aim of this study was to determine whether GBS colonization at delivery is associated with increased risk of maternal peripartum infection. METHODS: In this prospective cohort study, 1746 unselected women had a vaginal-rectal culture taken at the onset of labor. Diagnosis of maternal peripartum infection was based on a combination of two or more signs or symptoms including fever, breast pain, severe wound or pelvic pain, purulent discharge and abnormal laboratory tests including C-reactive protein and white blood cell count occurring from labor until 2 weeks postpartum. The main outcome measure was the proportion of women with maternal peripartum infection according to GBS colonization status. RESULTS: A total of 25.9% (452/1746) women were colonized with GBS. The rate of peripartum infection was almost twice as high in colonized women (49/452 [10.8%]) vs. non-colonized women (81/1294 [6.3%]); OR 1.82 [1.26-2.64], p = 0.002). This association was confirmed in a multivariable model (OR 1.99 [1.35-2.95], p = 0.001). Women diagnosed with peripartum infection had a significantly longer hospital stay compared to women without peripartum infection (4 days (median) vs. 3 days, p < 0.001). Length of hospital stay did not differ between colonized and non-colonized women. Serotype IV GBS was more frequent in colonized women with peripartum infection than in women without peripartum infection (29.3% vs. 12.5%, p = 0.003). CONCLUSIONS: GBS colonization at delivery is associated with increased risk of peripartum infection. Whether this increase is due directly to invasion by GBS or whether GBS colonization is associated with a more general vulnerability to infection remains to be determined.

RESUMO

Resistance to activated protein C (aPC) is most commonly due to the F5 rs6025 (factor V Leiden) polymorphism, which increases the risk of venous thrombosis. In the present population-based study of 313 cases and 353 controls, we investigated whether reduced sensitivity to aPC was associated with a history of pregnancy-related venous thrombosis. Calibrated automated thrombography was used to determine the sensitivity to aPC, and normalized aPC sensitivity ratio (n-aPC-sr) was calculated. Pregnant women and women using oral contraceptives and/or anticoagulants were excluded due to the effect on the n-aPC-sr. In women without the F5 rs6025 polymorphism, free tissue factor pathway inhibitor (TFPI), free protein S and protein C activity were associated with n-aPC-sr. Unadjusted odds ratio for venous thrombosis for women with n-aPC-sr in the 4th quartile as compared with n-aPC-sr below the 4th quartile was 2·4 (95% confidence interval 1·7-3·6). Adjusting for free protein S, free TFPI and age did not influence the odds ratios. Also in carriers of the F5 rs6025 polymorphism the risk for venous thrombosis was increased for women with higher n-aPC-sr. Our findings substantiate the importance of the aPC resistant phenotype as a risk factor for pregnancy-related venous thrombosis.

RESUMO

OBJECTIVE: To estimate incidence and risk factors for intrauterine fetal death (IUFD) in a Norwegian study-population applying two different control groups. DESIGN: Case-control study. SETTING: Two university hospitals in Oslo, Norway, January 1990 through December 2003. SAMPLE: The cases: 377 women with IUFD. CONTROLS: 1) all women delivering at the study-hospitals in the period (facility-based), and 2) 1 215 women with live births at one study-hospital in the period (selected). METHODS: Information from cases and selected controls was collected from medical records. Data on facility-based controls were provided by the Medical Birth Registry of Norway. Data were analyzed using chi-squared test and logistic regression. MAIN OUTCOME MEASURES: Incidence of IUFD and adjusted odds ratios of risk factors. RESULTS: The incidence was 4.1/1 000 deliveries. Small-for-gestational age (SGA) and placental abruption were the strongest risk factors for IUFD. Hypertensive disorders were of low risk if not associated with SGA. Low to moderate risk factors were pre-pregnancy diabetes mellitus, thyroid disease, placenta previa, gestational diabetes, smoking and twin pregnancy. Advanced maternal age was significant when compared with facility-based controls. Risk estimates pointed in the same direction independent of control-group. Hypertension appeared overestimated when using facility-based controls, whereas advanced age was underestimated in the analysis among selected controls. CONCLUSION: SGA has a strong association with IUFD, and the risk of hypertensive disorders is mediated through SGA. The other risk factors, except placental abruption, are of low prevalence and of limited importance in the prevention of a relatively low incidence, although dramatic, event like IUFD.

RESUMO

Assisted reproductive therapy (ART) increases the risk of venous thrombosis (VT) by 2- to 4-fold, whereas pregnancy increases the risk by 5- to 10-fold. Women with a history of VT undergoing ART are often suggested thromboprophylaxis. The literature is scarce and international guidelines are lacking. We made a review of the literature and base our suggestions primarily on expert opinions. We suggest women with a prior VT to use low-molecular-weight heparin as thromboprophylaxis starting from ovarian stimulation, throughout pregnancy, and 6 weeks postpartum. Assessment of VT risk should be done prior to ART. Adjustment of treatment to minimize the thrombotic risk, such as preventing ovarian hyperstimulation syndrome, single-embryo transfer, cryopreservation, and transfer of frozen embryos instead of fresh embryo in high-risk women, is suggested. Women with previous arterial thrombosis should continue aspirin during ART treatment, pregnancy, and postpartum.

RESUMO

OBJECTIVES: Exact knowledge of fetal station and position is of paramount importance for reliable surveillance of labor progress and a prerequisite for safe operative vaginal procedures. Detailed clinical assessments are thoroughly described in old textbooks, but almost forgotten in contemporary obstetrics. Ultrasound is suggested as an objective diagnostic tool in active labor. Several publications have demonstrated a low correlation between ultrasound and clinical assessment of fetal head station and position, but the methods of clinical assessment in these studies are poorly described. We wanted to explore if a quality clinical assessment could perform better than clinical assessment in previous publications, by analyzing the correlation between a structured method of clinical assessment and intrapartum ultrasound. METHODS: In all, 100 laboring women with cervical dilatation ≥7 cm were included in a prospective cohort study at Oslo University Hospital-Ullevål from October to December 2016. The study design was cross-sectional. Clinical examinations were performed by one special educated consultant (JKI), and transabdominal and transperineal ultrasound clips were recorded and examined by a blinded expert in intrapartum ultrasound (TME). Fetal position was classified as a clock face with 12 units (hourly divisions) and thereafter categorized as occiput anterior (OA), left occiput transverse (LOT), occiput posterior (OP), and right occiput transverse (ROT) positions. Fetal station was categorized clinically from -5 to +5 and measured with ultrasound as angle of progression (AoP) and head-perineum distance (HPD). AoP is the angle between a longitudinal line through the symphysis and a tangent to the head contour. HPD is the shortest distance between the fetal skull and the perineum. RESULTS: Eight women were excluded due to strong contractions between clinical assessments and ultrasound measurements, fetal distress, or incomplete examinations. Fetal position assessed with ultrasound and clinical examination agreed exactly in 48/92 (52%) of cases, within one unit (hour) in 87/92 (95%) of cases and within two units in 90/92 (98%) of cases. It differed by three units in one case and by five units in one case. The agreement categorized into OA, LOT, OP, and ROT was good (Cohen's kappa 0.72; 95% CI 0.61-0.84). For station, the agreement was very good for both HPD (Pearson correlation coefficient r = 0.86; 95% CI 0.80-0.91) and AoP (r = 0.77; 95% CI to 0.67-0.84). The correlation between HPD and AoP was good (r = 0.76; 95% CI 0.65-0.84). CONCLUSION: We found very good correlations between structured clinical assessments and ultrasound examinations, suggesting that an objective quality in clinical examinations is possible to achieve. More focus on clinical skills training may improve accuracy for clinicians.

RESUMO

BACKGROUND: Midpelvic vacuum extractions are controversial due to reports of increased risk of maternal and perinatal morbidity and high failure rates. Prospective studies of attempted midpelvic vacuum outcomes are scarce. Our main aims were to assess frequency, failure rates, labor characteristics, maternal and neonatal complications of attempted midpelvic vacuum deliveries, and to compare labor characteristics and complications between successful and failed midpelvic vacuum deliveries. STUDY DESIGN: Clinical data were obtained prospectively from all attempted vacuum deliveries (n = 891) over a one-year period with a total of 6903 births (overall cesarean section rate 18.2% (n = 1258). Student's t-test, Mann-Whitney U-test or Chi-square test for group differences were used as appropriate. Odds ratios and 95% confidence intervals are given as indicated. The uni- and multivariable analysis were conducted both as a complete case analysis and with a multiple imputation approach. A p-value of <0.05 was considered statistically significant. RESULTS: Attempted vacuum extractions from midpelvic station constituted 36.7% (n = 319) of all attempted vacuum extractions (12.9% (n = 891) of all births). Of these 319 midpelvic vacuum extractions, 11.3% (n = 36) failed and final delivery mode was cesarean section in 86.1% (n = 31) and forceps in the remaining 13.9% (n = 5). Successful completion of midpelvic vacuum by 3 pulls or fewer was achieved in 67.1%. There were 3.9% third-degree and no fourth-degree perineal tears. Cup detachments were associated with a significantly increased failure rate (adjusted OR 6.13, 95% CI 2.41-15.56, p< 0.001). CONCLUSION: In our study, attempted midpelvic vacuum deliveries had relatively low failure rate, the majority was successfully completed within three pulls and they proved safe to perform as reflected by a low rate of third-degree perineal tears. We provide data for nuanced counseling of women on vacuum extraction as a second stage delivery option in comparable obstetric management settings with relatively high vacuum delivery rates and low cesarean section rates.

RESUMO

INTRODUCTION: Quality of care is an important factor in reducing preventable maternal deaths, yet it is a significant challenge in many countries. Substandard and poor quality of care is the leading factor in two-thirds of maternal deaths in European countries. Our study investigated the deaths of all women of reproductive age in 2012 in Georgia. The aim was to define the underlying causes of maternal deaths and to identify the factors in women's care which contributed to the fatal outcomes. METHODS: A national Reproductive Age Mortality Survey was conducted in Georgia in 2014-15. Data from multiple sources was triangulated to identify all deaths of women of reproductive age. This was followed by verbal autopsy diagnoses. Each case of early and late maternal death was investigated through interviews and medical record reviews at the last medical facility providing care for the deceased woman. A specialist panel reviewed and assigned underlying causes of death, assessed the management of each woman's condition, and identified elements of suboptimal care. RESULTS: We identified a total of 23 maternal deaths, including 15 (65%) early and eight (35%) late deaths. The maternal mortality ratio was 26.3 per 100 000 live births. The four leading causes of early maternal deaths were: sepsis, hemorrhage, embolism, and pregnancy-induced hypertension. Embolism and sepsis were the direct causes of the eight late maternal deaths. Cancer, tuberculosis, and postpartum suicide constituted the indirect causes of death. Improvements in care which would have made a difference to the outcomes were identified in 87% of early maternal deaths and 67% of late maternal deaths due to direct obstetric causes. DISCUSSION: Delayed recognition and inappropriate management of maternal complications were common across almost all cases studied. The findings from Georgia highlight the conclusion that most maternal deaths were preventable and that improvement in obstetric care is urgently required.
