Effect of Growth Restriction on Fetal Heart Rate Patterns in the Second Stage of Labor

2015 
Objective  We aimed to estimate the effect of intrauterine growth restriction (IUGR) on electronic fetal monitoring (EFM) patterns in the second stage of labor. Study Design  We performed a 5-year retrospective cohort study of consecutive singleton, nonanomalous, term gestations. We compared IUGR infants, those with a birth weight less than the 10th percentile, with non-IUGR infants, those greater than or equal to the 10th percentile. Our primary outcome was the EFM patterns in the 30 minutes before delivery. A secondary analysis was performed excluding infants with composite morbidity. Logistic regression was used to adjust for body mass index, race, nulliparity, induction, and protracted labor. Results  Out of the 5,388 infants, 652 (12.1%) were IUGR. IUGR fetuses had less accelerations (29.0 vs. 35.9%, p p Conclusion  Growth restriction at term confers an increased risk of late decelerations, even in the absence of neonatal morbidity. EFM patterns may require different interpretations based on a priori risk and clinical factors.
