Fetal heart rate patterns in placenta abruption

ObjectiveTo explore the abnormal fetal heart rate (FHR) monitoring in cases of placenta abruption. MethodsA retrospective analysis was conducted in 56 pregnant women with placental abruption in The First Affiliated Hospital of Sun Yat-sen University from January 2015 to November 2019. ResultsUndetectable acceleration, minimal variability, variable deceleration and abnormal uterine contraction appeared more common in abnormal FHR tracings cases of placental abruption. The incidence of minimal variability was higher in no-labor group than labor group, and the differences were significant(χ²=12.07, P<0.01). Prolonged deceleration appeared significantly more frequently in labor group than in no-labor group(χ²=12.74, P<0.01). The incidence of abnormal uterine contraction was significantly higher in diagnosis-before group than in diagnosis-after group(χ²=14.54, P<0.01), whereas the pattern of variable deceleration was more frequent in diagnosis-after group (χ²=5.73, P=0.02). ConclusionsAccurate interpretation of fetal heart rate monitoring is helpful to early detection of placental abruption. When minimal variability, prolonged deceleration or abnormal uterine contraction appear, we should be alert to the occurrence of placental abruption.
