nonstress test and pregnancy

BACKGROUND: Pregnant women often experience anxiety due to pregnancy, negatively impacting their and their fetus' health. Non-pharmacological interventions, such as virtual reality (VR), could reduce anxiety levels, potentially impacting non-stress tests or the physiological responses of the pregnant woman and the fetus. METHODS: A randomized clinical trial conducted between February and December 2022 involved 286 term pregnant women. They were divided into a VR intervention group (146 women) and a control group (140 women)...

BACKGROUND: Prenatal tests cause high-risk pregnant women to experience high anxiety levels. AIM: This paper investigated the effect of Virtual Reality (VR) and music on anxiety, non-stress test parameters, and satisfaction of high-risk pregnant women undergoing non-stress tests (NSTs). METHODS: This was a randomized controlled trial. The sample consisted of 102 participants randomized into three groups (VR = 34, music = 34, and control = 34)...

INTRODUCTION: This study evaluated the effect of the noise level of the nonstress test (NST) device on stress parameters in primigravid women. METHODS: A total of 44 pregnant women participated in a randomized clinical trial between February and October, 2021. The participants were divided randomly into 4 equal groups using an automated web-based randomization system and ensuring allocation concealment: the control group (NST device volume turned off), intervention group I (1-35 dB(A)), intervention group II (36-60 dB(A)), and intervention group III (61 dB(A) and above)...

OBJECTIVE: Evidence regarding the clinical significance of a single sporadic variable deceleration (SSD) in reactive non-stress test (NST) is scarce, and optimal management has yet to be established. We aim to evaluate whether SSD during a reactive NST at term is associated with a higher risk for fetal heart rate decelerations during labor and the need for intervention. METHODS: This was a retrospective, case-control study of singleton term pregnancies at one university-affiliated medical center in 2018...

OBJECTIVE: This study aimed to determine whether maternal cortisol levels affect fetal heart rate patterns in primiparous pregnant women in the third trimester. METHODS: This cross-sectional descriptive study included 400 primiparous pregnant women with uncomplicated pregnancies between November and December 2022. The study included primiparous pregnant women over 18 years old in the third trimester who had not exercised for at least 2 h before the fetal heart rate monitoring and had a healthy pregnancy without consuming any food or drink...

Fetal growth restriction (FGR) is defined as an ultrasound (US)-determined estimated fetal weight or abdominal circumference less than the 10th percentile according to a population level reference curve. FGR affects up to 10% of pregnancies. Fetuses with FGR are at increased risk of intrauterine mortality and, postnatally, neonatal intraventricular hemorrhage, necrotizing enterocolitis, respiratory distress, hypoglycemia, and suboptimal neurologic, behavioral, and cognitive development. In early-onset FGR (ie, less than 32 weeks' gestation), a detailed US examination is recommended...

BACKGROUND: Uterine torsion is a rare obstetric event that can occur during pregnancy and is difficult to diagnose. Its occurrence may lead to serious adverse pregnancy outcomes. CASE INTRODUCTION: The patient was a 33-year-old woman at 30+ 5 weeks' gestation with a singleton pregnancy. The pregnancy course, including fetal growth, and prenatal examinations were regular. Except for a small amount of vaginal bleeding in early pregnancy and treatment with progesterone, there were no prenatal abnormalities, and the patient denied any trauma or sexual history...

OBJECTIVE: Modern technological advancements have made it possible to perform cardiotocography (CTG) at home. Home-based management of high-risk pregnancies using a mobile CTG system (iCTG) has been reported; however, its effectiveness in monitoring cases of fetal growth restriction (FGR) remains unclear. Therefore, we aimed to investigate the clinical usefulness of home-based telemedicine for FGR management using iCTG. METHODS: We conducted a single-center, retrospective case series of patients with FGR...

INTRODUCTION: Anxiety negatively affects pregnant women and their fetuses. It can cause misleading test readings in electronic fetal monitoring, affect the duration of the first stage of labor, and influence certain aspects related to childbirth. This study aimed to evaluate the effects of virtual reality and music therapy on anxiety levels, maternal and fetal physiologic parameters, and labor and birth outcomes. METHODS: A total of 343 full-term pregnant women participated in a randomized controlled trial and were divided into 3 parallel groups: music therapy intervention (n = 104), virtual reality intervention (n = 124), and control (n = 115)...

INTRODUCTION: In developing countries, nonstress test (NST) is the most widely used method for antenatal fetal surveillance.Lately, cerebroplacental ratio (CPR) has emerged as a predictor for adverse perinatal outcomes, especially in hypertensive disorders in pregnancy (HDP). Against this background, the present study was conducted with the primary objective of quantifying the diagnostic accuracy of cerebroplacental ratio (CPR) versus nonstress test (NST) in predicting adverse perinatal outcomes in women with HDP...

Background: Antenatal fetal surveillance is a field of increasing importance in modern obstetrics. It is based on fetal heart rate monitoring using nonstress test and contraction stress test, ultrasound biometry and amniotic fluid assessment, Doppler blood flow studies of fetal and uteroplacental circulation, and an evaluation of biophysical fetal parameters. The combination of these methods leads to improvements in fetal morbidity and mortality. Aim: The present study aimed to assess the sensitivity, specificity, and positive and negative predictive values of umbilical artery (UA) systolic/diastolic (S/D) ratio, and amniotic fluid index (AFI) in term pregnancies for the prediction of perinatal outcome and their relation with perinatal outcome...

OBJECTIVE: To estimate the impact of body mass index (BMI) categories on duration of the nonstress test (NST), and the need for additional tests of fetal wellbeing or interventions. METHODS: We conducted a retrospective cohort study of women with singleton pregnancies who had an NST for the indications of severe obesity (BMI ≥40 kg/m2 ), diabetes (pre-gestational or gestational), hypertensive disorders (chronic, gestational, and preeclampsia), and others between 1 January 2015 until 31 December 2016...

Introduction: Benign recurrent intrahepatic cholestasis is a rare hepatologic disorder characterized by recurrent, self-limited episodes of severe pruritus, jaundice, and elevated bile acids. While there are guidelines for the management of intrahepatic cholestasis of pregnancy, the literature regarding benign recurrent intrahepatic cholestasis and pregnancy is limited. Case: A 29-year-old G1P0 woman, with history of liver toxicity, had elevated total serum bile acid levels and liver enzymes documented at 8 weeks of gestation and throughout her pregnancy...

Coronavirus-19 disease is still a pandemic health problem and uncertainty in the management of severe or critically ill pregnant women confuses continually the obstetricians. The nationwide maternal mortality rate due to covid-19 still has not been presented in any study in Turkey. The study includes four maternal mortality cases in a referral single pandemic center in our country. Case 1, a 34-year-old, 34 weeks of gestation with moderate disease. The cesarean section was performed due to nonreassuring nonstress tests...

BACKGROUND: Cardiotocography or nonstress test is a technical means of recording the fetal heartbeat and uterine contractions for antenatal monitoring. OBJECTIVE: This study aimed to evaluate whether antepartum cardiotocography with computer analysis (computerized cardiotocography) increases the incidence of cesarean delivery in women with high-risk pregnancies but without intrauterine growth restriction. STUDY DESIGN: This was a parallel group nonblinded randomized clinical trial of singletons with high-risk pregnancies admitted for inpatient monitoring between 24 0/7 and 37 6/7 weeks' gestation...

OBJECTIVE: Pregnancies complicated by maternal preexisting diabetes have a 4-5-fold increased risk of stillbirth, and consequently routine antenatal nonstress testing (NST) was implemented into clinical practice decades ago. Though, international guidelines lack consensus and recommend anything from twice weekly testing from 32 weeks to once weekly testing from 38 weeks. The objective of this study was to examine how routine antenatal NST was used in centers with specific interest and dedication in the care of pregnant women with preexisting diabetes...

BACKGROUND: Remote pregnancy monitoring is one of the most promising applications of telemedicine; however, the diagnostic value of self-examination using mobile cardiotocography (CTG) devices and remote analysis of the subsequent results has never been properly studied. OBJECTIVES: The study aimed to compare the diagnostic usefulness of CTG self-examination using a mobile device to examination performed by a medical professional using a stationary device; and to evaluate the quality of CTG analysis performed remotely...

Snake envenomation during pregnancy is an uncommon emergency with several potential complications associated with the poisoning and its treatment. This case discusses a 27-y-old gravida 3, para 1102 (3 total pregnancies, 1 term birth, 1 premature birth, 0 abortions, 2 living births, twins) at 36 wk gestation who was bitten by a presumed Agkistrodon contortrix (copperhead snake). She had worsening pain and swelling in the right lower limb. Crotalidae polyvalent immune Fab was administered. The patient felt significantly better with improvement in swelling...
