Evaluating uterine electrohysterogram with entropy

Abstract

In this report, we evaluate complexity of the uterine EHG during labor by estimation of entropy. Two methods for entropy eva7luation have been chosen: approximate entropy and sample entropy. Our observation, based on three labors, that have been randomly chosen from our database, show that sample entropy indicates the course of labor. The values of sample entropy are higher during the latent phase then during the active phase of the labor. The complexity of uterine EHG signal is reduced in the active phase of labor. Sample values are also reduced after Oxytocin dose.
