The correlation between total deceleration and acceleration surface areas on electronic fetal monitoring and neonatal cord blood pH in postdate pregnancies.

Objective: To assess the correlation between the total decelerations area in the final 120 min before delivery and neonatal cord blood pH in postdate pregnancies.

Methods: This cross-sectional study included women with gestational age greater than 41 weeks, singleton pregnancy, and a category II electronic fetal monitoring (EFM) of at least 30 min during the final 120 min before delivery. We included postdate deliveries of an otherwise low-risk parturient population.
