Fifteen - Minute Assessment of Fetal Monitoring Based on Probability and S/k Ratio

Abstract

Introduction: The suitable interpretation of fetal monitoring is a challenge for current medicine; in 2012, a new diagnostic methodology was developed based on the theory of probability and entropy. This new diagnostic methodology managed to assess fetal monitoring objectively and reproducibly, establishing differences between monitorings with normal and abnormal patterns, and the process of evolution between them.
Objective: To verify the effectiveness of the clinical application of this new diagnostic methodology.
Methods: We assessed 10 fetal monitoring divided into two groups: five normal and five with loss of fetal well-being, according to the conventional clinical interpretation of monitoring. Heart rates were taken at discrete intervals from the tracings; the probability and S / k relation of the entropy of the monitors were calculated as well as the possibility of reducing the evaluation time.
Results: Correspondance was observed between the diagnoses established in 20 and 15 minutes, which allows demonstrating the diagnostic capacity of the physical-mathematical method, reducing the evaluation time.
Conclusions: The S / k ratio of entropy differentiated disease from normality objectively and reproducibly, reducing the evaluation time to 15 minutes.
