Successful management of fetal hypoxia due to amniotic banding at 26 weeks of pregnancy: A case report of a rare survival.

BACKGROUND: Amniotic banding is a rare condition that can lead to structural limb anomalies, fetal distress and adverse obstetric outcomes. The main hypothesis for its etiology is a rupture of the amniotic membrane in early pregnancy, with the formation of tightly entangling strands around the fetus. These strands can constrict, incise, and subsequently amputate limb parts, the neck or head. More rarely, the amniotic banding can affect the umbilical cord, leading to fetal distress or potential intra-uterine fetal demise. OBJECTIVE: We present a unique case of a 26-week pregnant woman who attended a polyclinical consultation due to reduced fetal movements with concerning cardiotocography (CTG) findings. A review of the literature about amniotic banding of the umbilical cord was conducted as well, identifying diagnostic and interventional options for the obstetrician's practice. STUDY DESIGN: This is a case report, alongside a review of the literature. RESULTS: The CTG indicated fetal distress, prompting an emergency caesarean section (C-section). Upon delivery, the neonate exhibited signs of amniotic band sequence, with distal phalangeal defects on the right hand and severe constriction of the umbilical cord caused by amniotic strands, the latter precipitating fetal hypoxia. Direct ultrasound diagnosis remains a challenge in the absence of limb amputation, yet indirect signs such as distal limb or umbilical doppler flow abnormalities and distal limb edema may be suggestive of amniotic banding. MRI is proposed as an adjuvant diagnostic tool yet does not present a higher detection rate compared to ultrasound. Fetoscopic surgery to perform lysis of the amniotic strands with favorable outcome has been described in literature. CONCLUSION: This case presents the first reported survival of an extremely preterm fetus in hypoxic distress as a cause of amniotic banding of the umbilical cord, with a rare degree of incidental timing. Ultrasound diagnosis remains the gold standard. Obstetrical vigilance is warranted, with fetal rescue proven to be feasible.

Short-term variation of the fetal heart rate as a marker of intraamniotic infection in pregnancies with preterm prelabor rupture of membranes: a historical cohort study.

INTRODUCTION: Intraamniotic infection (IAI) and subsequent early-onset neonatal sepsis (EONS) are among the main complications associated with preterm prelabor rupture of membranes (PPROM). Currently used diagnostic tools have been shown to have poor diagnostic performance for IAI. This study aimed to investigate whether the exposure to IAI before delivery is associated with short-term variation of the fetal heart rate in pregnancies with PPROM. METHODS: Observational cohort study of 678 pregnancies with PPROM, delivering between 24 + 0 and 33 + 6 gestational weeks from 2012 to 2019 in five labor units in Stockholm County, Sweden. Electronic medical records were examined to obtain background and exposure data. For the exposure IAI, we used the later diagnosis of EONS in the offspring as a proxy. EONS is strongly associated to IAI and was considered a better proxy for IAI than the histological diagnosis of acute chorioamnionitis, since acute chorioamnionitis can be observed in the absence of both positive microbiology and biochemical markers for inflammation. Cardiotocography traces were analyzed by a computerized algorithm for short-term variation of the fetal heart rate, which was the main outcome measure. RESULTS: Twenty-seven pregnancies were categorized as having an IAI, based on the proxy diagnosis of EONS after birth. Fetuses exposed to IAI had significantly lower short-term variation values in the last cardiotocography trace before birth than fetuses who were not exposed (5.25 vs 6.62 ms; unadjusted difference: -1.37, p = 0.009). After adjustment for smoking and diabetes, this difference remained significant. IAI with a later positive blood culture in the neonate (n = 12) showed an even larger absolute difference in STV (-1.65; p = 0.034), with a relative decrease of 23.5%. CONCLUSION: In pregnancies with PPROM, fetuses exposed to IAI with EONS as a proxy have lower short-term variation of the fetal heart rate than fetuses who are not exposed. Short-term variation might be useful as adjunct surveillance in pregnancies with PPROM.

Correlation between intrapartum CTG findings and interleukin-6 levels in the umbilical cord arterial blood: A prospective cohort study.

OBJECTIVE: to investigate the correlation between the intrapartum CardioTocoGraphic (CTG) findings "suggestive of fetal inflammation" ("SOFI") and the interleukin (IL)-6 level in the umbilical arterial blood. STUDY DESIGN: prospective cohort study conducted at a tertiary maternity unit and including 447 neonates born at term. METHODS: IL-6 levels were systematically measured at birth from a sample of blood taken from the umbilical artery. The intrapartum CTG traces were retrospectively reviewed by two experts who were blinded to the postnatal umbilical arterial IL-6 values as well as to the neonatal outcomes. The CTG traces were classified into "suggestive of fetal inflammation (SOFI)" and "no evidence of fetal inflammation (NEFI) according to the principles of physiologic interpretation the CTG traces. The CTG was classified as "SOFI" if there was a persistent fetal heart rate (FHR) increase > 10 % compared with the observed baseline FHR observed at the admission or at the onset of labor without any preceding repetitive decelerations. The occurrence of Composite Adverse Outcome (CAO) was defined as Neonatal Intensive Care Unit (NICU) or Special Care Baby Unit (SCBU) admission due to one or more of the following: metabolic acidaemia, Apgar score at 5 min ≤ 7, need of neonatal resuscitation, respiratory distress, tachypnoea/polypnea, jaundice requiring phototherapy, hypotension, body temperature instability, poor perinatal adaptation, suspected or confirmed early neonatal sepsis. MAIN OUTCOME MEASURES: To compare the umbilical IL-6 values between the cases with intrapartum CTG traces classified as "SOFI" and those classified as "NEFI"; to assess the correlation of umbilical IL-6 values with the neonatal outcome. RESULTS: 43 (9.6 %) CTG traces were categorized as "SOFI"; IL-6 levels were significantly higher in this group compared with the "NEFI" group (82.0[43.4-325.0] pg/ml vs. 14.5[6.8-32.6] pg/mL; p <.001). The mean FHR baseline assessed 1 h before delivery and the total labor length showed an independent and direct association with the IL-6 levels in the umbilical arterial blood (p <.001 and p = 0.005, respectively). CAO occurred in 33(7.4 %) cases; IL-6 yielded a good prediction of the occurrence of the CAO with an AUC of 0.72 (95 % CI 0.61-0.81). CONCLUSION: Intrapartum CTG findings classified as "SOFI" are associated with higher levels of IL-6 in the umbilical arterial blood.

Prediction of labour outcomes using prelabour computerised cardiotocogram and maternal and fetal Doppler indices: A prospective cohort study.

OBJECTIVES: To investigate the association and the potential value of prelabour fetal heart rate short-term variability (STV) determined by computerised cardiotocography (cCTG) and maternal and fetal Doppler in predicting labour outcomes. DESIGN: Prospective cohort study. SETTING: The Prince of Wales Hospital, a tertiary maternity unit, in Hong Kong SAR. POPULATION: Women with a term singleton pregnancy in latent phase of labour or before labour induction were recruited during May 2019-November 2021. METHODS: Prelabour ultrasonographic assessment of fetal growth, Doppler velocimetry and prelabour cCTG monitoring including Dawes-Redman CTG analysis were registered shortly before induction of labour or during the latent phase of spontaneous labour. MAIN OUTCOME MEASURES: Umbilical cord arterial pH, emergency delivery due to pathological CTG during labour and neonatal intensive care unit (NICU)/special care baby unit (SCBU) admission. RESULTS: Of the 470 pregnant women invited to participate in the study, 440 women provided informed consent and a total of 400 participants were included for further analysis. Thirty-four (8.5%) participants underwent emergency delivery for pathological CTG during labour. A total of 6 (1.50%) and 148 (37.00%) newborns required NICU and SCBU admission, respectively. Middle cerebral artery pulsatility index (MCA-PI) and MCA-PI z-score were significantly lower in pregnancies that required emergency delivery for pathological CTG during labour compared with those that did not (1.23 [1.07-1.40] versus 1.40 [1.22-1.64], p = 0.002; and 0.55 ± 1.07 vs. 0.12 ± 1.06), p = 0.049]. This study demonstrated a weakly positive correlation between umbilical cord arterial pH and prelabour log10 STV (r = 0.107, p = 0.035) and the regression analyses revealed that the contributing factors for umbilical cord arterial pH were smoking (p = 0.006) and prelabour log10 STV (p = 0.025). CONCLUSIONS: In pregnant women admitted in latent phase of labour or for induction of labour at term, prelabour cCTG STV had a weakly positive association with umbilical cord arterial pH but was not predictive of emergency delivery due to pathological CTG during labour.

Manejo de Disminución de Movimientos Fetales en pacientes del Área de Urgencias Obstétricas / Management of Decreased Fetal Movements in patients in the Obstetric Emergency Area

Los movimientos fetales son uno de los primeros signos de vitalidad fetal. Durante la gestación, éstos van apareciendo progresivamente. La adecuada adquisición y mantenimiento de los mismos durante la gestación indica un correcto desarrollo neuromuscular, así como de bienestar fetal1. La percepción materna de una Disminución de los Movimientos Fetales (DMF) constituye un motivo de consulta frecuente en los Servicios de Urgencias Obstétricas; toda paciente embarazada debe vigilar los movimientos fetales, mediante un conteo subjetivo de los movimientos del feto, a partir de las 24 semanas de gestación. La DMF constituye el 5 ­ 15% de motivos de consulta en los servicios de Urgencias en el tercer trimestre del embarazo. Hasta un 25% de fetos que presentan una DMF presentarán alguna complicación perinatal (malformaciones, retraso de crecimiento, parto prematuro, hemorragia fetomaterna, y éxitus fetal) incluso en población de bajo riesgo. El manejo inadecuado de la DMF representa un 10-15% de las muertes evitables a término1-3. Es por esto que ninguna paciente que consulte por Disminución de Movimientos Fetales debe ser dada de alta sin asegurarse del adecuado bienestar fetal.

Fetal movements are one of the first signs of fetal vitality. During gestation, they appear progressively. Adequate acquisition and maintenance of fetal movements during gestation indicates correct neuromuscular development, as well as fetal well-being1. Maternal perception of decreased fetal movements (DMP) is a frequent reason for consultation in Obstetric Emergency Departments; every pregnant patient should monitor fetal movements by subjectively counting fetal movements, starting at 24 weeks of gestation. FMD constitutes 5-15% of the reasons for consultation in the emergency department in the third trimester of pregnancy. Up to 25% of fetuses with FMD will present some perinatal complication (malformations, growth retardation, premature delivery, fetomaternal hemorrhage, and fetal death) even in low-risk populations. Inadequate management of FMD accounts for 10-15% of preventable deaths at term1-3. This is why no patient who consults for decreased fetal movements should be discharged without ensuring adequate fetal well-being.

Comparison between Protocols for Management of Fetal Growth Restriction / Comparação entre protocolos de acompanhamento da restrição de crescimento fetal

Abstract This comprehensive review compares clinical protocols of important entities regarding the management of fetal growth restriction (FGR), published since 2015. Five protocols were chosen for data extraction. There were no relevant differences regarding the diagnosis and classification of FGR between the protocols. In general, all protocols suggest that the assessment of fetal vitality must be performed in a multimodally, associating biophysical parameters (such as cardiotocography and fetal biophysical profile) with the Doppler velocimetry parameters of the umbilical artery, middle cerebral artery, and ductus venosus. All protocols reinforce that the more severe the fetal condition, the more frequent this assessment should be made. The timely gestational age and mode of delivery to terminate the pregnancy in these cases can vary much between the protocols. Therefore, this paper presents, in a didactic way, the particularities of different protocols for monitoring FGR, in order to help obstetricians to better manage the cases.

Resumo Esta revisão compreensiva compara protocolos clínicos de entidades importantes em relação ao manejo da restrição de crescimento fetal (RCF), publicados desde 2015. Cinco protocolos foram escolhidos para a extração de dados. Não houve diferenças relevantes quanto ao diagnóstico e classificação da RCF entre os protocolos. Em geral, todos os protocolos sugerem que a avaliação da vitalidade fetal deve ser realizada de forma multimodal, associando parâmetros biofísicos (como cardiotocografia e perfil biofísico fetal) aos parâmetros dopplervelocimétricos da artéria umbilical, artéria cerebral média e ducto venoso. Todos os protocolos reforçam que quanto mais grave a condição fetal, mais frequente essa avaliação deve ser feita. A idade gestacional oportuna e o modo de parto para interromper a gravidez nesses casos podem variar muito entre os protocolos. Portanto, este trabalho apresenta, de forma didática, as particularidades de diferentes protocolos de acompanhamento de RCF, a fim de auxiliar os obstetras no melhor manejo dos casos.

Intraoperative Neuromonitoring for Spinal Surgery in a Pregnant Patient: Case Report and Literature Review.

We report the strategy of anesthesia and intraoperative neurophysiological monitoring (IONM) in a 29-year-old, 22 weeks pregnant patient posted for surgery for aggressive vertebral body hemangioma. We used propofol and fentanyl-based anesthesia for IONM. Motor-evoked potentials (MEP) and somatosensory-evoked potentials (SSEP) were used to monitor the neural tracts during surgery. Fetal heart rate monitoring was done preoperatively and postoperatively. Train of 8, 75 µs duration pulse, 250-500 Hz stimulus was used for MEP and 30 mA, 200-400 µs, 3-5 Hz was used for SSEP. No new motor or somatosensory deficits appeared. Our findings suggest that IONM can be safely done in pregnant women.

Analysis of antepartum cardiotocography based on S/k proportions and probability in 20 minutes / Análisis de la cardiotocografía anteparto mediante las relaciones S/k y la probabilidad en 20 minutos

Abstract Objectives: although mortality and perinatal asphyxia in newborns have been considerably reduced, there are still deficiencies in screening and diagnosis methods for intrapartum fetal well being that aim to detect its early alterations. Therefore, the purpose of this research was to apply a methodology based on probability and entropy and confirm its capacity to detect normal and abnormal fetal cardiac dynamics from 20-minute cardiotocographic tracings. Methods: 80 cardiotocographic tracings of pregnant women in the last trimester were collected, of which the minimum and maximum fetal heart rate were evaluated every 10 seconds, as well as its repetitions along with their probability and the diagnostic S/k ratio. Finally, the statistical analysis was carried out to establish the diagnostic capacity of the method concerning the clinical evaluation and interpretation of the cardiotocographic tracing, taken as the Gold Standard. Results: it was confirmed that S/k ratio values differentiated normal from abnormal fetal cardiac dynamics with sensitivity and specificity values of 100% and a Kappa coefficient of 1. Conclusion: the applicability of a diagnostic mathematical method of cardiotocography was confirmed, which suggests its implementation in the clinical context to detect alterations in fetal well-being in 20 minutes.

Resumo Objetivos: aunque se ha logrado reducir considerablemente la mortalidad y asfixia perinatal en neonatos, aún hay deficiencias en los métodos de tamizaje y diagnóstico del bienestar fetal intraparto que detecten sus alteraciones tempranas. Por lo anterior, el propósito de esta investigación fue aplicar una metodología basada en la probabilidad y la entropía y confirmar su capacidad para diagnosticar la dinámica cardíaca fetal normal de la anormal a partir de trazados cardiotocográficos de 20 minutos. Métodos: se recolectaron 80 trazados cardiotocográficos de gestantes en el último trimestre, de los cuales se evaluaron frecuencia cardíaca fetal mínima y máxima cada 10 segundos al igual que sus repeticiones, su probabilidad y la proporción S/k diagnóstica. Finalmente, se realizó un análisis estadístico para establecer la capacidad diagnóstica del método con respecto a la interpretación el trazado cardiotocográfico y la evaluación clínica, tomadas como Gold Standard. Resultados: se confirmó que los valores de la proporción S/k diferenciaron las dinámicas cardíacas fetales normales de las anormales con valores de sensibilidad y especificidad del 100% y un coeficiente Kappa de 1. Conclusión: se confirmó la aplicabilidad de un método matemático diagnóstico de la cardiotocografía, lo cual sugiere que su implementación en la clínica para detectar alteraciones del bienestar fetal en 20 minutos.

Relationship Between Umbilical Cord Gas Values and Neonatal Outcomes: Implications for Electronic Fetal Heart Rate Monitoring.

OBJECTIVE: To evaluate the relationship between umbilical artery cord gas values and fetal tolerance of labor, as reflected by Apgar score. We hypothesized the existence of wide biological variability in fetal tolerance of metabolic acidemia, which, if present, would weaken one fundamental assumption underlying the use of electronic fetal heart rate (FHR) monitoring. METHODS: We conducted a retrospective cohort study of term, singleton, nonanomalous fetuses delivered in our institution between March 2012 and July 2020. Universally obtained umbilical cord gas values and Apgar scores were extracted. We calculated Spearman correlation coefficients and receiver operating characteristic curves for various levels of umbilical artery pH, base excess, and Apgar scores. RESULTS: We analyzed data from 29,787 deliveries. The statistical correlation between umbilical artery pH and base excess and both 1- and 5-minute Apgar scores was weak or nonexistent in all pH range subgroups (range 0.064-0.213). Receiver operating characteristic curve analysis suggested umbilical artery pH value of 7.22 yields the best discrimination for prediction of a severely depressed newborn (5-minute Apgar score less than 4), but sensitivity and specificity for this predictive value remains poor to moderate. CONCLUSION: The use of electronic FHR monitoring is predicated on a documented relationship between FHR patterns and umbilical artery pH, and an assumed correlation between pH and fetal outcomes, reflecting fetal tolerance of labor and delivery. Our data demonstrate a weak-to-absent correlation between metabolic acidemia and even short-term fetal condition, thus significantly weakening this latter assumption. No amount of future modification of FHR pattern interpretation to better predict newborn pH is likely to lead to improved newborn outcomes, given this weakness in a fundamental assumption on which FHR monitoring is based.

Factors associated with intrapartum ZigZag pattern of fetal heart rate: A retrospective one-year cohort study of 5150 singleton childbirths.

OBJECTIVES: Recent studies suggest that intrapartum ZigZag pattern of fetal heart rate (FHR) is significantly associated with cord blood acidaemia and neonatal complications. For the clinical significance of this pattern, it is mandatory that ZigZag episodes in cardiotocographic (CTG) recording are correctly identified. The aim of the present study was to examine maternal, fetal and delivery-related factors that could explain the occurrence of ZigZag pattern of FHR during the last 2 h of labour in a large obstetric cohort. STUDY DESIGN: CTG recordings from 5150 singleton childbirths at ≥33 weeks of gestation during one year were evaluated retrospectively and blinded to pregnancy and neonatal outcomes in a university hospital in Helsinki, Finland. All women in the cohort were in the active phase of labour with regular uterine contractions. ZigZag FHR pattern was defined as FHR baseline amplitude changes of >25 bpm with a duration of 2-30 min. The following maternal, fetal and labour/delivery-related variables were determined: maternal age, obesity (prepregnancy BMI ≥ 30.0 kg/m2), parity, preeclampsia, maternal fever ≥38.0 °C, smoking, gestational age at delivery, fetal sex, birth weight z-score, mode of delivery, and type of onset of labour. RESULTS: ZigZag pattern occurred in 582/5150 (11.3 %) cases, and only in childbirths after 37 weeks of gestation. Fetal male gender (OR 3.29; 95 % CI 2.70-4.02), nulliparous pregnancy (OR 2.60; 95 % CI 2.15-3.15) and post-term gestational age (≥42 weeks) (OR 1.92; 95 % CI 1.47-2.48) were independently associated with the occurrence of ZigZag pattern. Among the three significant risk factors, clustering of two or three factors was associated with an increase of the ZigZag pattern occurrence risk to 5.0-16.4-fold (95 % CI 3.16-31.60). CONCLUSIONS: ZigZag pattern occurred in term pregnancies after 37 weeks of gestation only. Fetal male gender, nulliparity and post-term pregnancy are significantly associated with ZigZag FHR pattern during the last two hours of labour. Identification of maternal, fetal and delivery-related variables are imperative in order to interpret correctly the findings of CTG and to prevent adverse neonatal outcome.

Opioid effect on the autonomic nervous system in a fetal sheep model.

PURPOSE: Opioid use during labour can interfere with cardiotocography patterns. Heart rate variability indirectly reflects a fluctuation in the autonomic nervous system and can be monitored through time and spectral analyses. This experimental study aimed to evaluate the impact of nalbuphine administration on the gasometric, cardiovascular, and autonomic nervous system responses in fetal sheep. METHODS: This was an experimental study on chronically instrumented sheep fetuses (surgery at 128 ± 2 days of gestational age, term = 145 days). The model was based on a maternal intravenous bolus injection of nalbuphine, a semisynthetic opioid used as an analgesic during delivery. Fetal gasometric parameters (pH, pO2, pCO2, and lactates), hemodynamic parameters (fetal heart rate and mean arterial pressure), and autonomic nervous system tone (short-term and long-term variation, low-frequency domain, high-frequency domain, and fetal stress index) were recorded. Data obtained at 30-60 min after nalbuphine injection were compared to those recorded at baseline. RESULTS: Eleven experiments were performed. Fetal heart rate, mean arterial pressure, and activities at low and high frequencies were stable after injection. Short-term variation decreased at T30 min (P = 0.02), and long-term variation decreased at T60 min (P = 0.02). Fetal stress index gradually increased and reached significance at T60 min (P = 0.02). Fetal gasometric parameters and lactate levels remained stable. CONCLUSION: Maternal nalbuphine use during labour may lead to fetal heart changes that are caused by the effect of opioid on the autonomic nervous system; these fluctuations do not reflect acidosis.

Spinal Emergency Surgery During Pregnancy: Contemporary Strategies and Outcome.

BACKGROUND: Low back pain is a common complaint during pregnancy. However, spinal pathologies, which manifest with severe pain, radiculopathy, and acute neurologic deficits because of disk herniation or mass lesions require special attention. Here, we present our interdisciplinary experience in the surgical management of spinal emergencies during pregnancy. METHODS: The data of pregnant women who underwent surgery for spinal pathologies over a 10-year period were collected. Patient-related characteristics such as maternal age, gestational age, preoperative workup, signs and symptoms of mothers, and diagnostic procedures were evaluated. After an interdisciplinary conference, individualized treatment plans regarding available options were developed. Fetal Doppler and cardiotocography were obtained before and after surgery. RESULTS: Nine pregnant women presented with spinal disorders and underwent spinal emergency surgery within the study period. The mean maternal age was 32.2 years. Six women presented with lumbar disk herniations manifesting as severe sciatica or foot drop and 3 patients had thoracic mass lesions resulting in cauda equine syndrome and/or ataxia. The mean gestational age at the time of presentation was 26.5 weeks. Caesarean sections were performed in 3 women prior to the neurosurgical procedure, whereas the pregnancies were maintained in the 6 other patients. Eight infants who were healthy at birth had an unremarkable development. CONCLUSIONS: Surgery for spinal emergencies in pregnancy can be performed safely according to individual treatment plans developed by an interdisciplinary team taking into account the expectant mother's decision. Maintenance of pregnancy is possible and feasible in most patients.

Implementation of a multidisciplinary perinatal emergency response team improves time to definitive obstetrical evaluation and fetal assessment.

BACKGROUND: Trauma is the leading cause of nonobstetric death during pregnancy and is associated with an increased risk of maternal and fetal mortality. In an effort to improve the delivery of care to pregnant trauma patients, we developed an institutional multidisciplinary quality initiative designed to improve response times of nontrauma specialists and ensure immediate availability of resources. We hypothesized that implementation of a perinatal emergency response team (PERT) would improve time to patient and fetal evaluation and monitoring by the obstetrics (OB) team and improve both maternal and fetal outcomes. METHODS: We performed a 6-year (2012-2018) retrospective cohort analysis of consecutive pregnant trauma patients presenting to our university-affiliated, level I trauma center. Patients in the pre-PERT cohort (before April 2015) were compared with a post-PERT cohort. Variables analyzed included patient demographics, mechanism of injury, Injury Severity Score, and level of trauma activation. The main outcome measure was time to OB evaluation. Secondary outcomes included time to cardiotocometry, and mortality. RESULTS: Of 92 pregnant trauma patients, there were 50 patients (54.3%) in the pre-PERT cohort and 42 (45.7%) in the post-PERT group. Blunt injuries predominated (98.9%), with the most common mechanism being motor vehicle collisions (76.1%), followed by assaults (13%) and falls (6.5%). The mean time to obstetrical evaluation was 44 minutes in the pre-PERT cohort compared with 14 minutes in the post-PERT cohort (p = 0.001). There was a significant decrease in level I (highest acuity) trauma activations pre-PERT and post-PERT (46% vs. 21%, p = 0.01), and the time to cardiotocography was significantly decreased post-PERT implementation (72 vs. .37 min, p = 0.01) CONCLUSION: Implementation of a multidisciplinary PERT improves time to evaluation by the OB team and time to cardiotocometry in the pregnant trauma patient. LEVEL OF EVIDENCE: Retrospective review, level IV.

Is moderate intensity exercise during pregnancy safe for the fetus? An open clinical trial / Exercício de intensidade moderada durante a gravidez é seguro para o feto? Ensaio clínico aberto

Abstract Objective To determine the effect of treadmill walking on maternal heart rate (MHR) and cardiotocographic parameters (basal fetal heart rate [FHR], active fetal movements [AFM], number of accelerations and decelerations, and short-term variation [STV] and long-term variation [LTV] of fetal heart rate) in pregnant women at 36 weeks. Methods A nonrandomized, open clinical trial involving 88 healthy pregnant women submitted to moderate intensity walking and computed cardiotocography in 3 20- minute periods (resting, treadmill walking, and postexercise recovery). Results The mean FHR decreased during walking (resting: 137 bpm; treadmill: 98 bpm; recovery: 140 bpm; p<0.001), with bradycardia occurring in 56% of the fetuses in the first 10minutes of exercise, and in 47% after 20minutes. Bradycardia was not detected in the other phases. The mean STV and HV were 7.9, 17.0, and 8.0 milliseconds (p<0.001) and 7.6, 10.8 and 7.6 bpm (p=0.002) in the resting, walking and recovery phases, respectively. Themean number of fetalmovements in 1 hour was 29.9, 22.2 and 45.5, respectively, in the 3 periods (p<0.001). In overweight/obese women, the mean FHR was lower (p=0.02). Following the logistic regression analysis, two variables remained significantly associated with bradycardia: maternal fitness in the 28th week of pregnancy (protective effect) and maternal weight (increased risk). Conclusion In healthy fetuses, physical exercise proved to be safe, since, although FHR and AFM decreased during treadmill walking, an increase in SVT and LTV was observed.

Resumo Objetivo Determinar o efeito da caminhada em esteira sobre a frequência cardíaca materna (FCM) e parâmetros cardiotocográficos (batimentos cardiofetais basais [BCFs], movimentos ativos fetais [MAFs], número de acelerações e desacelerações e variabilidade de curta [STV] e longa [LTV] duração da frequência cardíaca fetal) em gestantes na 36a semana. Métodos Foi realizado umensaio clínico não randomizado e aberto com 88 gestantes saudáveis submetidas a caminhada de moderada intensidade na esteira e a cardiotocografia computadoriza em 3 momentos de 20 minutos (antes, durante e após a caminhada). Resultados A média dos BCFs diminuiu durante a caminhada, retornando a níveis prévios (antes: 137 bpm; durante: 98 bpm; após: 140 bpm; p<0,001), com bradicardia ocorrendo em 56% dos fetos nos primeiros 10 minutos do exercício, e em 47% após 20 minutos. A bradicardia fetal não foi observada em outrosmomentos (antes ou depois). As médias da STV e da LTV foram 7,9, 17,0 e 8,0milissegundos (p<0,001) e 7,6, 10,7 e 7,6 bpm (p=0,002) antes, durante e após a caminhada, respectivamente. Amédia dos números dos MAFs em 1 hora foi 29,9, 22,2 e 45,5, respectivamente, nos três momentos (p<0,001). Nas mulheres com sobrepeso/obesidade, a média da FCM foi menor (p=0,02). Após a análise de regressão logística, duas variáveis permaneceram significativamente associadas a bradicardia: aptidão maternal na 28a semana de gravidez (efeito protetor) e peso materno (aumento do risco). Conclusão Em fetos saudáveis, o exercício físico mostrou-se seguro, uma vez que, embora os BCFs e osMAFs diminuam durante a caminhada na esteira, foi observado um aumento da SVT e da LTV.

Slow-release vaginal insert of misoprostol versus orally administrated solution of misoprostol for the induction of labour in primiparous term pregnant women: a randomised controlled trial.

OBJECTIVE: To compare the World Health Organization (WHO) recommended orally administrated dosage of misoprostol (25 µg) with a vaginal slow-release (7 µg/hour) insert of misoprostol regarding time from induction to delivery and safety of the method. DESIGN: Open label, Randomised controlled trial (RCT). SETTING: Delivery ward at a secondary referral hospital in Stockholm, Sweden, from 1 October 2016 to 21 February 2018. POPULATION: One hundred and ninety-six primiparous women with singletons in cephalic presentation at ≥37 weeks of gestation and with a Bishop score of ≤4. METHODS: Women were randomised to an oral solution of misoprostol (Cytotec® n = 99) or vaginal slow-release misoprostol (Misodel® [MVI] n = 97). MAIN OUTCOME MEASURES: Primary outcome: time from induction to vaginal delivery. SECONDARY OUTCOMES: mode of delivery; proportion of vaginal deliveries within 24 hours (VD24); neonates with an Apgar score of <7 at 5 minutes; pH < 7.10; postpartum haemorrhage (PPH) of >1000 ml; hyperstimulation; and women's delivery experience (VAS). RESULTS: There was no difference in the time to delivery [corrected] (median 21.1 hours in the MVI group and 23.2 hours in the oral group; Kaplan-Mayer log rank P = 0.31). There was no difference regarding the proportion of VD24 (50.5 versus 55.7%, P = 0.16). Hyperstimulation with non-reassuring cardiotocography (CTG) was more common in the MVI group (14.4 versus 3.0%, P < 0.01). Terbutaline (Bricanyl® ) was used more often for hyperstimulation in the MVI group (22.7 versus 4.0%, P < 0.01). There was no difference in the numbers of children admitted to the neonatal intensive care unit (NICU). CONCLUSIONS: Vaginal delivery after induction of labour (IOL) with slow-release misoprostol did not result in a shorter time from induction to vaginal delivery, compared with oral misoprostol solution, but was associated with a higher risk for hyperstimulation and fetal distress. There were no differences in mode of delivery or neonatal outcome. TWEETABLE ABSTRACT: IOL with MVI was similar to oral solution of misoprostol but hyperstimulation and fetal distress were more common.

Cerebral regional tissue Oxygen Saturation to Guide Oxygen Delivery in preterm neonates during immediate transition after birth (COSGOD III): an investigator-initiated, randomized, multi-center, multi-national, clinical trial on additional cerebral tissue oxygen saturation monitoring combined with defined treatment guidelines versus standard monitoring and treatment as usual in premature infants during immediate transition: study protocol for a randomized controlled trial.

BACKGROUND: Transition immediately after birth is a complex physiological process. The neonate has to establish sufficient ventilation to ensure significant changes from intra-uterine to extra-uterine circulation. If hypoxia or bradycardia or both occur, as commonly happens during immediate transition in preterm neonates, cerebral hypoxia-ischemia may cause perinatal brain injury. The primary objective of the COSGOD phase III trial is to investigate whether it is possible to increase survival without cerebral injury in preterm neonates of less than 32 weeks of gestation by targeting cerebral tissue oxygen saturation (crSO2) using specified clinical treatment guidelines during the immediate transition period after birth (the first 15 min) in addition to the routine monitoring of arterial oxygen saturation (SpO2) and heart rate (HR). METHODS/DESIGN: COSGOD III is an investigator-initiated, randomized, multi-center, multi-national, phase III clinical trial. Inclusion criteria are neonates of less than 32 weeks of gestation, decision to provide full life support, and parental informed consent. Exclusion criteria are severe congenital malformations of brain, heart, lung, or prenatal cerebral injury or a combination of these. The premature infants will be randomly assigned to study or control groups. Both groups will have a near-infrared spectroscopy (NIRS) device (left frontal), pulse oximeter (right palm/wrist), and electrocardiogram placed immediately after birth. In the study group, the crSO2, SpO2, and HR readings are visible, and the infant will receive treatment in accordance with defined treatment guidelines. In the control group, only SpO2 and HR will be visible, and the infant will receive routine treatment. The intervention period will last for the first 15 min after birth during the immediate transition period and resuscitation. Thereafter, each neonate will be followed up for primary outcome to term date or discharge. The primary outcome is mortality or cerebral injury (or both) defined as any intra-ventricular bleeding or cystic periventricular leukomalacia (or both). Secondary outcomes are neonatal morbidities. DISCUSSION: crSO2 monitoring during immediate transition has been proven to be feasible and improve cerebral oxygenation during immediate transition. The additional monitoring of crSO2 with dedicated interventions may improve outcome of preterm neonates as evidenced by increased survival without cerebral injury.
