Objectives
Narrative objectives1
We conducted "A retrospective study to construct a scoring system for predicting neonatal acidemia using 5-tier classification of fetal heart rate"(UMIN000040395) as a preliminary study. We have found our new scoring system (Integrated score index to predict fetal acidemia: iPREFACE score) could be the candidate for predicting fetal acidemia during the second stage of labor. The purpose of this study is to verify the usefulness and validity of the iPREFACE score by evaluating its relationship the course of pregnancy/delivery and the outcome of the newborns.

CTG findings for approximately 30 minutes during the second stage of labour until delivery were used for scoring. All decelerations, except prolonged deceleration, were evaluated at the level of the 5-tier classification, and the sum of all numbers of these levels was calculated as the score. Prolonged deceleration was defined as a multiplication of the duration (minutes) by the number of the level on the 5-tier classification. The durations (minutes) were expressed as whole numbers.
