P04.01: Intrapartum PRSA: a new method to predict fetal acidosis?

Acute hypoxic acidosis during labour leads to a central nervous system and cardiovascular reaction of the infant. Phase-rectified signal averaging method (PRSA), represents a new computer-based method for the assessment of the fetal autonomic nervous system. It allows the quantification of the speed of changes in fetal heart rate by calculating the average deceleration capacity (ADC). Objectives of this study were to test its ability to predict...
