The incidence of fetomaternal hemorrhage (FMH) after external cephalic version (ECV) has been poorly reported. In this study, we evaluated the frequency of FMH, diagnosed by positive Kleihauer–Betke test (KBT), after ECV attempt and then evaluate the relevance of its routine use after procedure. A total of 282 women with a term breech presentation and who had ECV attempt were recruited from January 2014 and December 2018. After ECV attempt, women were systematically screened for FMH using KBT. Data on ECV attempt, KBT results, perinatal and neonatal outcomes were collected and compared between women with positive (cases) and negative KBT (controls) after ECV. The success rate of ECV was 22.0% (62/282). Eight women (2.9%) experienced transient fetal heart rate (FHR) abnormalities after ECV. In five (1.8%) women, KBT was positive after ECV. Obstetrical management was modified for two of these five women due to continuous positivity of KBT at day 1 and day 7 controls after ECV attempt. A cesarean section was planned 7 days earlier due to persistent high FMH on day 7 (6 mL fetal blood) in one woman and the labor was induced for persistent high FMH on day 7 (20 mL fetal blood) for another woman. No newborns have signs of fetal anemia at birth and there was no significant difference in neonatal status between two groups. FMH after ECV attempt are rare, and no negative fetal or neonatal outcomes were observed when KBT was positive, even strongly (>5 mL fetal blood). It appears that systematic KBT after attempted ECV is probably not useful.

Introduction.Fetomaternal hemorrhage represents a transfer of fetal blood to the maternal circulation. Although many etiologies have been described, most causes of fetomaternal hemorrhage remain unidentified. The differentiation between acute and chronic fetomaternal hemorrhage may be accomplished antenatally and may influence perinatal management.Case.A 36-year-old gravida 6 para 3 presented at 37 and 5/7 completed gestational weeks with ultrasound findings suggestive of chronic fetal anemia such as right ventricular enlargement, diminished cerebral vascular resistance, and elevated middle cerebral artery end-diastolic velocity. On the other hand, signs of acute fetal decompensation such as deterioration of the fetal heart tracing, diminished biophysical score, decreased cord pH, and increased cord base deficit were noted. Following delivery, the neonate’s initial hemoglobin was 4.0 g/dL and the maternal KB ratio was 0.015 indicative of a significant fetomaternal hemorrhage.Discussion.One should consider FMH as part of the differential diagnosis for fetal or immediate neonatal anemia. We describe a unique case of FMH that demonstrated both acute and chronic clinical features. It is our hope that this case will assist practitioners in differentiating acute FMH that may require emergent delivery from chronic FMH which may be able to be expectantly managed.

Abstract BACKGROUND The optimal mode of delivery for preterm infants remains controversial, and routine Caesarean sections (C/S) are not recommended, except for maternal indications. Nonetheless, many preterm infants are delivered by C/S, particularly those in breech presentation, and recent retrospective data have suggested that these infants may have improved outcomes. OBJECTIVES To examine whether C/S as the mode of preterm delivery is associated with decreased mortality and improved short term outcomes. DESIGN/METHODS This retrospective, population-based cohort study examined infants with a gestational age between 23 0/7 weeks and 32 6/7 weeks, born between January 1, 2007 and December 31, 2016, and admitted to the Neonatal Intensive Care Unit at a single Canadian Tertiary Care hospital. Infants with major congenital anomalies were excluded. Data were abstracted from the local Neonatal-Perinatal database for all infants. Two groups, those delivered vaginally and those delivered by C/S, were compared for major neonatal outcomes including the primary outcomes of death and severe intraventricular hemorrhage (IVH), defined as grade 3 or higher. RESULTS A total of 1442 infants met inclusion criteria (784 born by C/S and 658 vaginally). There was no significant difference in neonatal mortality (7.0% vs 7.1%, p=0.925) or severe IVH (6.1% vs 7.4%, p=0.317). There was, however, a significant difference in the incidence of IVH, any grade (19.9% vs 27.5%, p=0.001), which remained after controlling for other significant predictors. There were no other significant differences in the secondary outcomes examined including need for extensive resuscitation, respiratory distress syndrome, bronchopulmonary dysplasia, patent ductus arteriosus, necrotizing enterocolitis, periventricular leukomalacia, or retinopathy of prematurity. CONCLUSION Caesarean section was not associated with decreased mortality in preterm infants, relative to vaginal births. Caesarean section was associated with a reduced rate of IVH (any grade) and there was a trend towards decreased severe IVH which may warrant further study.

Objective To estimate the effect of oligohydramnios on fetal heart rate (FHR) patterns in patients undergoing induction of labor (IOL) at term. Study Design Secondary analysis of a prospective cohort study of consecutive term, singleton deliveries from 2010 to 2015. We included all patients who underwent IOL. Our primary outcomes were electronic fetal monitoring (EFM) characteristics in the 2 hours preceding delivery. Outcomes were compared between those induced with oligohydramnios and those induced without a diagnosis of oligohydramnios. Our secondary outcome was composite neonatal morbidity. Logistic regression was used to control for confounders. Results Of 3,787 patients who underwent IOL, 147 had a diagnosis of oligohydramnios and 3,640 were included in the no oligohydramnios group. There was no significant difference in EFM characteristics between the two groups. There was no difference in composite neonatal morbidity. In patients with oligohydramnios, EFM patterns with baseline tachycardia for 30 minutes or greater were significantly associated with composite neonatal morbidity (31.3 vs. 5.3% adjusted odds ratio 8.63, 95% confidence interval 2.18, 34.1]). Conclusion Term patients undergoing IOL with oligohydramnios had EFM patterns that did not differ from their induced peers.

Background The gentle caesarean section (GCS) is an alternative to the conventional caesarean section. It aims to optimise the wellbeing of mother and child by mimicking certain aspects of a vaginal delivery when a caesarean section is indicated. Aim To compare the maternal and neonatal outcomes of a GCS in cephalic and breech presentation. Methods In this retrospective study, the outcomes of 180 women who underwent a GCS were analysed, where 120 fetuses were in cephalic and 60 were in breech position. Comparisons were made using Chi-square, Mann-Whitney U and t-tests. Maternal and neonatal outcomes were analysed. Results Apgar 1 was significantly lower for breech position (P=0.019). The Apgar 5 and 10 showed no difference. Neonatal temperature was slightly lower in breech position (36.8°C ± 0.36 versus 36.9°C ± 0.39, P=0.046). Birthweight was significantly lower for breech position (P=0.009). Blood loss was significantly higher in cephalic position (441 ± 230 versus 353 ± 151, P=0.002). Conclusions When performing a GCS, there is no clinically significant difference in maternal or neonatal outcome between a cephalic and a breech presentation. It seems safe to perform a GCS for breech presentation.

First Trimester Of Pregnancy

The aim of this study was to create a fetal heart rate (FHR) reference curve for singleton bovine fetuses in the first trimester of gestation and to determine its possible relationship with the outcome of pregnancy. Forty-eight Holstein-Friesian cows with one fetus and five cows with twins were used. Fetal heart beatings were recorded on videotape during transrectal scanning with a 5 and/or 7.5 MHz linear array transducer on a weekly basis between Days 40 and 95 of gestation. FHR was calculated by averaging the results of five counts of the same record by the same observer. For singleton pregnancies, a reference curve was created using the mean, the standard deviation (SD) and the 5th and 95th percentiles. The FHR increased from Days 40–46 (173 beats/min) to Days 61–67 (183 beats/min). After a peak, the FHR decreased slowly until Days 89–95 (175 beats/min), while the SD increased. There was no significant difference between singleton and twin fetuses. in the aborted and lost fetuses in twin gestation due to fetal reduction, both bradycardia and tachycardia were detected compared to the singleton pregnancy reference curve.
