OBJECTIVES: To describe the antenatal fetal heart rate (FHR) parameters analyzed by computerizedcardiotocography (cCTG) in fetuses with gastroschisis and compare the FHR parameters with ultrasound gastrointestinal markers.
METHODS: A retrospective analysis of antepartum cCTG records were conducted in 87 pregnant cases with fetal gastroschisis between 28and 36 weeks (plus 6 days). A comparative analysis of the median distribution of the following FHR parameters was performed: basal FHR, short-term variation (STV), FHR accelerations and decelerations, episodes of high and low variations, and variations in low and high episodes. FHR parameters and ultrasound gastrointestinal markers were also compared.
RESULTS: The majority of FHR parameters did not present significant changes throughout gestation. An increased number of records with episodes of low variation (p = 0.019) and an increased number of accelerations >15 bpm (p = 0.001) were the only observed changes throughout gestation. Stomach herniation was significantly associated with a lower STV (p = 0.018) and a higher frequency of records with low episodes (p = 0.049).
CONCLUSIONS: The cCTG analysis indicated that the FHR parameters in fetuses with gastroschisis presented different patterns from those observed in normal fetuses. Stomach herniation was associated with altered FHR patterns.
