“…This result has already been observed in the literature [8] [14] Open Journal of Obstetrics and Gynecology [15]. Indeed, a Spanish case-control study demonstrated that decelerations occurring during the last 30 minutes of labor were the best marker of neonatal acidosis [14].…”

Introduction: Fetal heart rate monitoring during labor is used to study fetal well-being and predict neonatal acidosis of newborn. Fetal heart rate monitoring is analyzed by the obstetrical team and categorized according to the FIGO guidelines. An important limitation of this diagnostic tool is an interand intra-observer variability, leading to subjective cardiotocography interpretation and classification. Our objective was to study the association between the categories of fetal heart rate analysis (according to FIGO classification) and neonatal acidosis of full-term newborns. Study design: This is a multicenter retrospective cohort study conducted between 2014 and 2018 in the GrandEst region. We searched and included retrospectively children hospitalized in a pediatric intensive care unit in one of the participating hospitals with an ICD-10 coding type "P91.6" corresponding to "Hypoxic Ischemic Encephalopathy". Maternal, pregnancy, delivery, and newborn characteristics were collected and compared by univariate logistic regression with multiple imputation. Odds Ratio and 95% confidence intervals (CI) were calculated using the model and presented. Multiple imputation with m = 100 imputations was tested, using Rubin rules to combine the results. Results: 55 patients were included in the study. Fetal heart rate tracings classified in Category 3 as "pathological" according to FIGO guidelines were significantly associated with an increased risk of severe neonatal acidosis. Late decelerations and bradycardia during labor were associated with severe neonatal acidosis. Conclusion: Severe neonatal acidosis may be suspected by interpretation of fetal heart rate during labor. Fetal bradycardia and late decelerations are pre

“…Graham et al also showed that total deceleration area (calculated with the same equation as in the study by Cahill) during the last 30 and 60 min differed significantly between a group of acidemic fetuses with encephalopathy and a control group . Furthermore, Marti et al studied the relation between total deceleration area during the last 30 min of labor and found a significant relation to fetal acidemia . However, to be able to use deceleration area as a parameter measured continuously during labor, a computerized method for assessment is needed.…”

“…32 A recently published case-control study of 204 infants also found that deceleration area was the superior feature to identify infants with acidemia. 33 These led us to hypothesize that deceleration area might be an important predictor of acidemia and morbidity within a large, modern, and unselected cohort. Additionally, the predictive value of tachycardia within our study remains consistent with findings from animal studies, which suggests that with labor-like cord occlusions there is an increase in the magnitude and slope of the fetal heart rate.…”

Deceleration area is the most predictive electronic fetal monitoring pattern for acidemia, and combined with tachycardia for significant risk of morbidity, from the electronic fetal monitoring patterns studied. It is important to acknowledge that this study was performed in patients delivering ≥37 weeks, which may limit the generalizability to preterm populations. We also did not use computerized analysis of the electronic fetal monitoring patterns because human visual interpretation was the basis for the Eunice Kennedy Shriver National Institute of Child Health and Human Development categories, and importantly, it is how electronic fetal monitoring is used clinically.

Deceleration area and fetal acidemia

Abstract: Total deceleration area showed the greatest predictive ability for fetal acidemia and its measure could help to estimate intrapartum fetal acid-base status.
