“…Among these 28 women, 18 were pregnant between 35-39 weeks. After 35-39 weeks, the mobility of the fetal head decreases, and the fetus begins to take the position it will present at delivery, leading to image windows that are less clear [30,31]. Although a great effort was made to overcome technical limitations of advanced gestational age, it seems that this gestational age prevents observing differences between the nearfar side of PSV.…”

We purposed to investigate the di ference between nearfield and far-field of PI (pulsatility index) and peak systolic velocity (PSV) of the middle cerebral artery (MCA) that are important in the management of fetal growth restriction and fetal anemia. Methods: This prospective study was conducted with 130 single uncomplicated pregnancies. Doppler was applied to near-and far-field of proximal MCA while PSV and PI were recorded and compared between two sides as well as according to body mass index (BMI) and gestational weeks of participants. Results: There was no statistically significant di ference between near and far-fields of MCA PI (P = 0.75). However, a statistically significant di ference in PSV was observed (P = 0.03), and this was especially noticeable in women with normal BMI (P = 0.009). On the other hand, there was no di ference between MCA PI or PSV in women with a BMI higher than 25. Also, no significant difference was observed between groups, which were subcategorized according to gestational weeks. Conclusions: Our data suggest that the far-field PSV values may be higher than near-field MCA PSV values; sonographers should bear in mind that while far and near-field PSV can di fer, conversely MCA PI can safely be assessed from both the near and far-fields of MCA in case of technical di ficulty.

“…In developed countries, 5-9% of all deliveries occur preterm [1]. Preterm pregnancy itself is also known as the most significant risk factor for breech presentation at delivery [2][3][4][5]. Risk factors for breech presentation in preterm deliveries are premature rupture of membranes, preeclampsia, oligohydramnios, fetal growth restriction, and congenital anomalies [6].…”

Background In many countries, vaginal breech labor at term is an option in selected cases. However, the safety of vaginal breech labor in preterm is still unclear. Therefore our study aimed to evaluate the safety of vaginal breech labor in late preterm deliveries. Design A retrospective register-based study. Setting Maternity hospitals in Finland, 2004–2017. Participants The study population included 762 preterm breech deliveries at 32 + 0—36 + 6 gestational weeks according to the mode of delivery, 535 (70.2%) of them were born vaginally in breech presentation, and 227 (29.8%) were delivered by non-urgent cesarean section. Methods The study compared short-term neonatal adverse outcomes of singleton vaginal breech deliveries with non-urgent cesarean deliveries at 32 + 0 to 36 + 6 weeks of gestation. An odd ratio with 95% confidence intervals was calculated to estimate the relative risk of adverse outcomes. Outcome measures Neonatal death, an arterial umbilical pH below seven, a five-minute Apgar score below four and seven, admission to neonatal intensive care unit, neonatal intubation, neonatal antibiotic therapy, neonatal birth trauma, respiratory distress syndrome, neonatal convulsions, cerebral ischemia, hypoxic-ischemic encephalopathy, congenital hypotonia, and a composite of severe adverse outcomes. Results A five-minute Apgar scores below seven were increased in vaginal breech labor at 32 + 0 to 36 + 6 weeks of gestation compared to non-urgent cesarean sections (aOR 2.48, 95% CI 1.08–5.59). Neonatal antibiotic therapy, the admission to neonatal intensive care unit, and neonatal respiratory distress syndrome were decreased after vaginal breech labor compared to the outcomes of non-urgent cesarean section (neonatal antibiotic therapy aOR 0.60, 95% CI 0.40–0.89; neonatal NICU admission aOR 0.47, 95% CI 0.33–0.68; respiratory distress syndrome aOR 0.30, 95% CI 0.19–0.48). Conclusion Vaginal breech labor at 32 + 0—36 + 6 gestational weeks does not increase severe neonatal short-term morbidity or mortality compared to cesarean section.

Adverse gestational events associated with prenatal, perinatal and postnatal variables in the Neonatal ICU

Objective: To analyze whether maternal, obstetric, anthropometric and postnatal variables of neonates admitted to the neonatal intensive care unit (NICU) are different in pregnant women who had adverse gestational events (AGE). In addition, it seeks to analyze whether AGE are predictors of mortality. Methods: Observational, retrospective and quantitative study, with a descriptive and inferential approach based on the medical records of patients seen at the tertiary reference hospital in health located in a municipality in Pará, during 2017. Data were collected to verify the relationship between present and absent AGE. Results: AGE (+) were associated with alcoholism, loss of amniotic fluid, premature labor, breench presentation, increased capillary glycemia and pneumonia. AGE (-) were associated with absent prenatal care, intact amniotic membrane, amniotic fluid with thick meconium and fetal trauma at birth. The other data were not significant. Conclusion: Maternal, obstetric, anthropometric and postnatal variables in neonates admitted to the nicu are associated with AGE (+). The events analyzed did not increase the chances of death.
