Is there an increased risk of cesarean section in obese women after induction of labor? A retrospective cohort study.

BACKGROUND: Obesity is increasing in Sweden and is also of huge global concern. Obesity increases the risk of complications during pregnancy and the need for the induction of labor. Induction of labor increases the number of complications during delivery, leading to women with more negative birth experience. This study investigated how maternal body mass index (BMI) during antenatal care enrollment affects labor outcomes (proportion of cesarean section at induction of labor). METHOD: This was a retrospective cohort study of 3772 women with mixed parity and induction of labor at Soderhospital, Stockholm, in 2009-2010 and 2012-2013. The inclusion criteria were simplex, ≥34 gestational weeks, cephalic presentation and no previous cesarean section. The women were grouped according to BMI, and statistical analyzes were performed to compare the proportion of cesarean sections after induction of labor. The primary outcome was the proportion of cesarean section after induction of labor divided by group of maternal BMI. The secondary outcomes were postpartum hemorrhage >1000 ml, time of labor, fetal outcome data, and indication for emergency cesarean section. RESULT: The induction of labor in women with a high BMI resulted in a significantly increased risk of cesarean section, with 18.4-24.1% of deliveries, depending on the BMI group. This outcome persisted after adjustment in women with BMI 25-29.9 (aOR 1.4; 95% CI; 1.1-1.7) and BMI 30-34.9 (aOR 1.5; 95% CI; 1.1-2.1). There was also a significantly higher risk for CS among primiparous women (aOR 3.6; 95% CI; 2.9-45) and if the newborn weighted ≥ four kilos (aOR 1.6; 95% CI; 1.3-2.0). CONCLUSION: Our findings show that a higher BMI increased the risk of cesarean section after induction of labor in the groups with BMI 25-34.9. Parity seems to be the strongest risk factor for CS regardless other variables.

Inadequacy of gestational weight gain during high-risk pregnancies is not associated with household food insecurity.

BACKGROUND: Inadequate gestational weight gain (GWG) is associated with adverse outcomes in maternal and child health and can be enhanced by social inequalities, such as lower education and household food insecurity (HFI). Women are more vulnerable to HFI, which has been associated with negative health effects for pregnant women during the prenatal and puerperal periods, particularly in regard to the aggravation of pregnancy risks. This study investigated the association between sociodemographic characteristics and HFI with respect to adequacy of total GWG among women with high-risk pregnancies. METHODS: This was a prospective cohort study that evaluated the total GWG of 169 pregnant women. The women were seen at a public university hospital in the metropolitan region of Rio de Janeiro (Brazil). Their sociodemographic and gestational characteristics and the Brazilian Scale of Domestic Food Insecurity were investigated. To estimate the total GWG, the difference between the patient weight at the last prenatal visit and the initial patient weight was verified, with both collected from the medical records of the pregnant women. The classification of the total GWG considered the recommendations of the Institute of Medicine (IOM) (2009). A multinomial logistic regression model assessed the risk (odds ratio; OR) and confidence intervals (CI 95%)) of insufficient and excessive GWG with exposure to HFI and other covariates (p value <0.05). RESULTS: Insufficient and excessive GWG were observed in 27.8% and 47.9% of the pregnant women, respectively. More than half of the women (74.6%) had a high education level. Exposure to mild HFI occurred in 44.2% of the women. After adjustment, the HFI was not associated with insufficient or excessive GWG. The educational level of women was the only variable significantly associated with a lower risk of GWG insufficiency (OR: 0.10; 95% CI: 0.01-0.89). CONCLUSIONS: In this population, higher maternal education was a protective factor against insufficient GWG. We highlight the importance of additional health support and counseling for women in the most vulnerable social conditions, considering the importance of access to information for reducing health risks.

Creating a novel strategy to reduce unnecessary laboratory testing based on healthcare cost analysis in high-risk pregnancies and delivery ward.

INTRODUCTION: Inappropriate request for laboratory tests is a challenging problem and an important cause for additional healthcare costs. Indeed, it may have further ambiguity for the clinicians. This study aimed to design an education-based program to reduce unnecessary laboratory testing orders and the associated costs. MATERIALS AND METHODS: In this interventional prospective study that took place in an educational hospital, the type and frequency of selected laboratory testing requested by gynecology, and obstetrics residents in the patients with gestational diabetes mellitus, preeclampsia, preterm labor, and premature preterm rupture of the membrane as well as cesarean section and normal vaginal delivery were analyzed periodically in a 1-year interval. At the same time, continuous educational supports and monitoring were performed. The results were compared before and after interventions. RESULTS: The educational intervention regardless of the etiologies of the admission, decreased the requested laboratory testing significantly (p < 0.001), except for CBC. Indeed, no near misses or delays in treatment were observed. Cost analysis showed a 31.3% reduction of expenses per inpatient day due to the decrease in the number of daily laboratory testing ordered. CONCLUSIONS: Appropriate education and continuous monitoring of the residents could reduce the unrequired laboratory testing as well as healthcare costs.

Sexo e gravidez de alto risco: uma comparação da função sexual entre segundo e terceiro trimestres / High-risk sex and pregnancy: a comparison of sexual function between second and third trimesters

Objetivo: Esta pesquisa teve como objetivo avaliar o impacto da gestação sobre a função sexual feminina, comparando se houve diferença significativa entre os dois últimos trimestres gestacionais. Métodos: Foi realizada no serviço de Ginecologia e Obstetrícia do Hospital Universitário Evangélico Mackenzie, por meio do questionário Female Sexual Function Index (IFSF). Cento e quinze pacientes foram divididas em dois grupos (T2, correspondente ao segundo trimestre gestacional; T3, correspondente ao terceiro trimestre gestacional), apresentando taxa de disfunção sexual de 47,8%, prevalente em gestantes do grupo T3. Resultados: Houve diferen- ça significativa, entre o segundo e o terceiro trimestre, nas médias do IFSF e nas variáveis excitação, orgasmo e dor, resultando em disfunção sexual prevalente em gestantes do terceiro trimestre gestacional. Conclusão: Não houve diferença significativa nas variáveis desejo, lubrificação e satisfação.(AU)

Objective: The objective of this study was to evaluate the impact of pregnancy on female sexual function, comparing if there was significant difference between the last two gestational trimester. Methods: The research was accomplished in the Gynecology and Obstetrics of Mackenzie Evangelical University Hospital, applying the Female Sexual Function Index (IFSF). One hundred and fifteen patients were combined in two groups (T2 corresponding the second gestational trimester; T3 corresponding the third one), with sexual dysfunction rate of 47.8%, mainly the T3 group. Results: The IFSF's average between the second and the third gestational trimester was significantly different, also the sexual arouse, orgasm and pain variables are higher in the second trimester resulting in sexual dysfunction mostly of pregnant women in the third gestational trimester. Conclusion: The desire, lubrication and satisfaction variables did not have significant difference.(AU)

Neurodevelopment of high and low-risk pregnancy babies at 6 months of age.

OBJECTIVE: to compare neurodevelopment differences between babies born from low-risk pregnancies and babies born from high-risk pregnancies. STUDY DESIGN: Longitudinal design SETTING: Spain PARTICIPANTS: A total of 91 women participated in the study, divided into two groups: 49 women in the low-risk pregnancy group and 42 women in the high-risk group. MEASUREMENT AND FINDINGS: The average amount of cortisol in pregnant mothers' hair was determined in both groups. Following their birth, the babies' neurodevelopment was evaluated using the Bayley-III instrument at 6 months of age and a new sample of cortisol was obtained from both the baby and the mother. The results showed that pregnancy risk group could predict cognitive, fine motor, gross motor and general motor neurodevelopment. KEY CONCLUSIONS: These results seem to show that an appropriate treatment tailored to the needs of individualised pregnancies may favor babies' neurodevelopment, including that of babies born from high-risk pregnancies. IMPLICATIONS FOR RESEARCH: It is essential to take special care of pregnant women no matter their medical condition and offer them the best medical care available.

Maternal and newborn outcomes of antenatal breastmilk expression: a scoping review protocol.

INTRODUCTION: Mothers with diabetes face unique challenges associated with breastfeeding initiation and maintenance. Antenatal breastmilk expression (BME) may be suggested to mothers, including mothers with diabetes, to improve breastfeeding, maternal, and infant outcomes postpartum. However, there have been few evaluations of the potential harms and benefits of this practice. The objective of our scoping review will be to broadly examine the literature describing maternal and infant outcomes of antenatal BME. METHODS AND ANALYSIS: This scoping review will address the research question: 'Among women who engaged in antenatal BME, what maternal and infant outcomes have been evaluated?' A search of published and unpublished studies available in English will be conducted in February 2020 using the following databases: Medline (OVID), Embase (OVID), CINAHL (EBSCOHost), and Cochrane Database of Systematic Reviews (OVID). A search of the British Library E-Theses Online Services (EThOS) database and OpenGrey will be conducted to identify relevant grey literature. This scoping review will use a five-step framework to guide the selection, extraction, and analysis of eligible studies. Clinical consultation will be included as a sixth step to our methodology. Literature reporting on the effect of antenatal BME on maternal and infant outcomes, breastfeeding initiation and duration, and the experiences of women who have engaged in the practice will be considered. The data will be summarised with attention paid to high-risk obstetrical populations such as women with diabetes. Our results will be reported as outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. ETHICS AND DISSEMINATION: Research ethics board approval will not be required due to the nature of the study's methodology. The results of this review will be disseminated through peer-reviewed publication and presentation at relevant conferences. TRAIL REGISTRATION NUMBER: Open Science Framework (osf.io/gfp2q).

Pregestational diabetes in pregnancy: Complications, management, surveillance, and mechanisms of disease-A review.

Diabetes is an increasingly common diagnosis among pregnant women. Pregestational diabetes is associated with an increase in many adverse pregnancy outcomes, which impact both on the woman and her fetus. The models of pregnancy care for women with diabetes are based largely on observational data or consensus opinion. Strategies for aneuploidy screening and monitoring for fetal well-being should be modified in women with diabetes. There is an increasing understanding of the mechanisms by which congenital anomalies and disorders of fetal growth occur, involving epigenetic modifications, changes in gene expression in critical developmental pathways, and oxidative stress. This knowledge may lead to pathways for improved care for these high-risk pregnancies.

Maternal cardiac function in women at high risk for pre-eclampsia treated with 150 mg aspirin or placebo: an observational study.

OBJECTIVE: To compare maternal haemodynamics in women at low and high risk for preterm pre-eclampsia (PE), and between those at high risk who are randomised to aspirin or placebo. DESIGN: Prospective, longitudinal observational study. SETTING: Maternity units in six UK hospitals. POPULATION: Women participating in the Aspirin for Prevention of Preterm Pre-eclampsia (ASPRE) trial. The population comprised three groups of women: low risk for preterm PE (n = 1362), high risk for preterm PE treated with aspirin (n = 208) and high risk for preterm PE on placebo (n = 220). METHODS: Women had four visits during pregnancy: 11-14, 19-24, 30-34, and 35-37 weeks' gestation. Blood pressure was measured with a device validated for pregnancy, and PE and maternal haemodynamics were assessed with a bioreactance monitor at each visit. A multilevel linear mixed-effects analysis was performed to examine longitudinal changes of maternal haemodynamic variables, controlling for demographic characteristics, past medical history and medication use. MAIN OUTCOME MEASURES: Longitudinal changes of cardiac output (CO), mean arterial pressure (MAP), and peripheral vascular resistance (PVR). RESULTS: The low-risk group demonstrated the expected changes with an increase in CO and reduction in MAP and PVR, with a quadratic change across gestation. In contrast, the high-risk groups had a declining CO, and higher MAP and PVR during pregnancy. The administration of aspirin did not appear to affect maternal haemodynamics. CONCLUSIONS: Women screened as high risk for preterm PE have a pathological cardiac adaptation to pregnancy and the prophylactic use of aspirin (150 mg oral daily from the first trimester) in this group may not alter this haemodynamic profile. TWEETABLE ABSTRACT: In women at high risk of pre-eclampsia, prophylactic use of aspirin may not alter the impaired maternal cardiac adaptation.

High-Risk Pregnancies and Their Impact on Neonatal Primary Hemostasis.

Primary hemostasis, similar to other systems in the adjusting and transitioning neonate, undergoes developmental adaptations in the first days of life. Although platelets of neonates do not differ quantitatively compared with those of adults, they functionally present with major differences, thus supporting the theory of a "hypofunctional" phenotype that is counterbalanced by high hematocrit and more potent von Willebrand factor multimers. No clinical effect of bleeding tendency has hence been established so far for healthy term neonates. However, discrepancies in functionality have been noted, associated with gestational age, with more pronounced platelet hyporesponsiveness in preterm neonates. Multiple methods of in vitro platelet function evaluation such as PFA-100/200, platelet aggregometry, flow cytometry, and cone and platelet analyzer have been used for assessment of neonatal primary hemostasis. Several pregnancies are characterized as "high-risk" when risk factors preexist in maternal history or evolve during pregnancy. These pregnancies require specialized observation as they may have unpredictable outcome. High-risk pregnancies include clinical entities such as preeclampsia, pregnancy-induced smoking during pregnancy, gestational diabetes mellitus (GDM), autoimmune diseases, and other maternal hematological conditions. In some cases, like systemic lupus erythematosus, antiphospholipid antibody syndrome, and maternal immunologically based thrombocytopenia, neonatal thrombocytopenia is regarded as a prominent hemostasis defect, while in others, like pregnancy-induced hypertension and preeclampsia, both quantitative and qualitative disorders of neonatal platelets have been reported. In other pathologies, like GDM, neonatal primary hemostasis remains vastly unexplored, which raises the need for further investigation. The extent to which primary hemostasis is affected in neonates of high-risk pregnancies is the main objective of this narrative review.

A comprehensive review on scientific evidence-based effects (including adverse effects) of yoga for normal and high-risk pregnancy-related health problems.

Women undergo distinct physiological changes and stress during pregnancy that are accompanied by various physical and psychological demands. Yoga is a complementary therapy that is commonly used by pregnant women and recommended by healthcare professionals. Thus, it is very important to know its evidence based effects, including adverse effects from all types of research. A comprehensive literature search in PubMed/Medline electronic database from inception to 23 September 2017 was performed using the keywords "yoga for pregnancy". In total, 137 articles published since 1979 were available. Of the 137 articles, 53 articles were included for the review. This comprehensive review suggests that yoga could be considered as an evidence-based complementary therapy in improving both physical and psychological wellbeing in pregnant women during pregnancy (normal and high-risk), childbirth, and post-partum. However, types, duration, and frequency of yoga practices varied among the studies and the exact mechanisms behind the effects of yoga are less understood and need to be explored.

Aortic dissection during pregnancy - obstetric perspective.

The risk of vascular events during pregnancy is substantially increased. Beyond comparatively frequent vascular diseases, pregnancy may lead also to the development of exceptionally rare vascular events such as the aortic dissection and aortic rupture which are conceivably endangering life conditions. Women with the connective tissue disorders and with a family history of the aorta diseases are especially prone to the aortic complications which may also develop in the absence of these risk factors due to the pregnancy-induced structural changes of the aortic wall. The preconception counselling is vital for patients with aortopathies to assess the risk of the aortic dissection and to establish the most appropriate care plan including the surgical intervention. This review presents the management guidelines in patients with the aortic dissection risk during pregnancy.

Calcium intake in high-risk pregnant women assisted in a high-complexity hospital.

Pregnancy is characterized by physiological changes. One of these changes involves calcium. During this period, an increased in calcium excretion occurs as well as an increased intestinal absorption and renal reabsorption, so that the adequate growth and development of the fetus can happen. Low calcium intake is associated with chronic diseases, such as diabetes and hypertension, which have negative impact on both mother and fetus. This study aimed to evaluate the average calcium intake of high-risk pregnant women, assisted in a clinic of high complexity service and correlated with chronic diseases. To perform this study, it was used a food frequency questionnaire. As a result, high-risk pregnant women showed daily calcium intake lower than the recommended by DRI during this period. Hypertensive or diabetic pregnant women showed lower average intake of calcium. Significant association between calcium intake and nutritional status was not observed. Calcium supplementation was present, however, at low percentage in the groups with hypertensive pregnant women. To analyze the relation between calcium intake and the comorbidities, as well as calcium intake and the nutritional status of the pregnant women, it was used one-way analysis of variance and Bonferroni multiple comparison. Further studies are required for evaluating other parameters that justify the low calcium intake among this population group, and the definition of pathways for the management of the nutritional deficit considering the possible damage to maternal and neonatal health in the short and long term.

Association Between Lactation and Postpartum Blood Pressure in Women with Preeclampsia.

PURPOSE: Preeclampsia affects 3% to 8% of all pregnancies. There are two distinct subtypes; early- (<34 weeks) and late-onset (≥34 weeks). Each subtype is associated with increased risk of cardiovascular disease. Lactation has been shown to improve cardiovascular outcomes. The purpose of this study was to describe lactation practices among women with each subtype of preeclampsia and determine the association between lactation and blood pressure at the initial postpartum visit. STUDY DESIGN AND METHODS: This retrospective cohort study included 246 subjects; 120 early- and 126 with late-onset preeclampsia who gave birth to live singleton newborns at a large suburban tertiary referral center in south central Pennsylvania between January 2012 and June 2016. Electronic health records were reviewed and data abstracted. Univariate and bivariate analyses were conducted. RESULTS: There was a significant difference in breastfeeding intent (p = .004) as well as rate of breastfeeding at maternal hospital discharge (p< .001) by preeclampsia subtype. However, there was no difference in rate of breastfeeding at the initial postpartum visit (p = .21) between subtypes. There was a significant difference in systolic (p = .03) and diastolic (p = .04) blood pressure between those breastfeeding and those who were not breastfeeding at the initial postpartum visit. CLINICAL IMPLICATIONS: Healthcare providers should provide women with preeclampsia clear and consistent messaging about importance of breastfeeding during pregnancy and the postpartum period on its association with improved neonatal outcomes, and specifically education on the cardioprotective benefit of sustained lactogenesis.

Cardiac output measurements during high-risk Cesarean section using electrical bioreactance or arterial waveform analysis: assessment of agreement.

OBJECTIVE: Maternal hemodynamics change significantly during Cesarean section complicated by massive hemorrhage or severe hypertensive disease. Cardiac output (CO) monitoring aids early, goal-directed hemodynamic therapy. The aim of this study was to record hemodynamic changes observed during Cesarean section in pregnancies at high risk of hemodynamic instability, using invasive (LiDCOrapid™) and non-invasive (NICOM®) devices, and to assess agreement between the two devices in measuring CO. METHODS: Simultaneous intraoperative hemodynamic measurements were taken using the LiDCOrapid and NICOM devices, following standardized techniques, in women at high risk of hemodynamic instability undergoing Cesarean section. Agreement in CO measurements between the two devices was assessed using Bland-Altman plots and the agreement:tolerability index (ATI). Agreement analyses were performed for repeated measures in subjects, using centiles. RESULTS: From 10 women, 307 paired measurements were analyzed. Mean bias (defined as the mean difference in CO measurements between the LiDCOrapid and NICOM devices) was 3.05 (95% CI, 1.89 to 4.21) L/min. Limits of agreement ranged from -1.58 (95% CI, -4.47 to -0.14) to 7.68 (95% CI, 6.24 to 10.56) L/min. The resulting agreement interval was 9.26 L/min which returned an ATI of 2.3. CONCLUSIONS: There are large mean differences between CO measurements obtained during Cesarean section using the LiDCOrapid and NICOM hemodynamic monitors in pregnant women at high risk of hemodynamic instability, indicating that they should not be considered interchangeable clinically. There is an unacceptably low level of agreement (ATI > 2) in CO measurements between the devices, conferring a high risk of clinical misclassification during massive hemorrhage.

Pregnancy in idiopathic non-cirrhotic portal hypertension: A multicentric study on maternal and fetal management and outcome.

BACKGROUND & AIMS: A total of 15% of patients with idiopathic non-cirrhotic portal hypertension (INCPH) are women of childbearing age. We aimed to determine maternal and fetal outcome of pregnancies occurring in women with INCPH. METHODS: We retrospectively analyzed the charts of women with INCPH followed in the centers of the VALDIG network, having had ≥1 pregnancy during the follow-up of their liver disease. Data are represented as median (interquartile range). RESULTS: A total of 24 pregnancies occurred in 16 women within 24 (5-66) months after INCPH diagnosis. Four women had associated partial portal vein thrombosis before pregnancy. At conception, 2 out of the 16 women had detectable ascites and others were asymptomatic. Out of these 24 pregnancies, there were four miscarriages, one ectopic pregnancy, and one medical termination of pregnancy at 20 weeks of gestation. Out of the 18 other pregnancies reaching 20 weeks of gestation (in 14 patients), there were nine preterm and nine term deliveries. All infants were healthy at delivery, but one died at day 1 of unknown cause and one at day 22 of infectious meningitis; both were preterm. Concerning mothers, two had worsening of ascites, two had variceal bleeding despite non-selective betablockers during pregnancy and one developed a main portal vein thrombosis in early postpartum. Genital bleeding occurred in three patients, including two receiving anticoagulation. All 16 women were alive and asymptomatic after a median follow-up of 27 (9-93) months after last delivery. CONCLUSION: The overall outcome of women with INCPH who become pregnant is favorable despite a significant incidence of complications related to portal hypertension. Fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation. LAY SUMMARY: About 15% of patients with idiopathic non-cirrhotic portal hypertension are women of childbearing age, who can become pregnant. As available reports on pregnancy in these women are scarce and heterogeneous, it is unclear whether or not pregnancy should be contraindicated in this setting. We provide detailed data showing that, regardless of the associated conditions, the overall outcome of women with idiopathic non-cirrhotic portal hypertension becoming pregnant is good despite a significant incidence of complications related to portal hypertension, and that fetal outcome is favorable in most pregnancies reaching 20 weeks of gestation.

Mechanisms and Clinical Significance of Endothelial Dysfunction in High-Risk Pregnancies.

The maternal cardiovascular system undergoes critical anatomic and functional adaptations to achieve a successful pregnancy outcome which, if disrupted, can result in complications that significantly affect maternal and fetal health. Complications that involve the maternal cardiovascular system are among the most common disorders of pregnancy, including gestational hypertension, preeclampsia, gestational diabetes, and impaired fetal growth. As a central feature, maternal endothelial dysfunction is hypothesized to play a predominant role in mediating the pathogenesis of these high-risk pregnancies, and as such, might proceed and precipitate the clinical presentation of these pregnancy disorders. Improving or normalizing maternal endothelial function in high-risk pregnancies might be an effective therapeutic strategy to ameliorate maternal and fetal clinical outcomes.

Pregnancy after Solid Organ Transplantation.

PURPOSE: To explore the reproductive decision-making process with women who were organ transplant recipients (renal, lung, & heart transplants). STUDY DESIGN AND METHODS: Grounded theory guided data collection and analyses. Mixed methods with audiotaped telephone interviews and a written survey measuring social support were used. As social support is critical for women who are organ transplant recipients considering pregnancy, a search for disconfirming evidence for social support via a survey and interviews was included. ANALYSES: Verbatim responses were analyzed through the constant comparative method using open, axial, and selective coding. Trustworthiness was established through prolonged engagement, member checking, and thick descriptions. RESULTS: Participants included 10 women who were solid organ recipients (2 lung, 1 heart, and 7 renal transplant recipients). The core theme was Wanting a child. Other themes included Getting information, Advocating, Dealing with problems, Preparing, Talking, Supporting, Coping, and Advising others. There was no evidence of a lack of social support as evaluated via the survey or interviews. CLINICAL IMPLICATIONS: This study provides new knowledge on clinical decision-making about pregnancy for women who are solid organ recipients and for healthcare professionals. Nurses can use these data to help guide women on how to obtain the most accurate information to make a personal decision about pregnancy and to develop support from their healthcare team and family.

Effect of Structured Bed Exercise on Uterine Contractions, Fetal Heart Rate Patterns, and Maternal Psychophysical Symptoms of Hospitalized High-Risk Pregnant Women: A Randomized Control Trial.

PURPOSE: This study examined the effect on uterine contraction frequency (UCF), blood pressure (BP), heart rate (HR), fetal heart rate (FHR) patterns and psychophysical symptoms (physical discomfort, anxiety, and depression) of structured bed exercise (SBE) in hospitalized high-risk pregnant women prescribed bed rest. METHODS: Forty-five hospitalized high risk pregnant women at >24 weeks of pregnancy prescribed bed rest were randomly assigned to the experimental or control group. From January to May 2014, data were collected using electronic fetal monitoring and patient monitoring of UCF, BP, HR and FHR patterns, and psychophysical symptoms were measured using the antenatal physical discomfort scale, state-trait anxiety scale, and Edinburgh postnatal depression scale. RESULTS: UCF, BP, HR, and FHR patterns (rate, variability, acceleration, and deceleration) did not differ significantly between the experimental and control groups. The experimental group showed a significant increase in baseline FHR after SBE within the normal range, and after SBE, it reduced to the FHR before SBE. The variability, acceleration and deceleration of FHR before and after SBE did not differ significantly between two groups. Moreover, there was no statistically significant difference before and after SBE in the experimental group. Also, the experimental group showed statistically significant decreases in physical discomfort score. However, there were no significant differences in depression and anxiety score between two groups. CONCLUSIONS: SBE in hospitalized high-risk pregnant women under bed rest did not increase the risk to the fetus, and relieved physical discomfort and anxiety. Therefore, SBE should be considered as a nursing intervention in hospitalized high-risk pregnant women.
