INTRODUCTION: In the anomalous fetus, the significance of an abnormal heart rate tracing is not clear because underlying nervous system perturbations may be responsible rather than acidemia. Recently, the National Institute for Child Health and Human Development suggested national nomenclature for fetal heart rate patterns, classified into three categories. The objective of this study was to classify fetal heart rate patterns in the anomalous fetus according to National Institute for Child Health and Human Development and compare the findings with normal laboring fetuses.
METHODS: A retrospective case-control study of 116 consecutive pregnancies who delivered at Temple University Hospital at greater than 25 weeks of gestation where the neonate had one or more anomaly controls were matched to pregnancies without a diagnosis of a neonatal anomaly before discharge. The primary outcome of the study was to calculate the prevalence of abnormal intrapartum fetal heart tracings in anomalous compared with nonanomalous fetuses in labor.
RESULTS: Preterm labor and preterm premature rupture of membranes were significantly higher, whereas gestational age was lower, in the anomaly group. Table 1 summarizes fetal heart rate tracing findings in the five time periods studied in the anomalous fetus compared with controls. These results demonstrated difference in the electronic fetal heart rate monitor only in the interval 30 minutes after admission. Fetal tachycardia was significantly more common on the anomalous fetus. There was no difference in the baseline variability. Prevalence of accelerations was significantly higher in normal fetuses.
CONCLUSIONS: Category 3 tracings were not increased in the anomalous fetus. Category 2 tracings were more common in the control group but deliveries by cesarean more common in the anomalous group.
