Evolución de las curvas del trabajo de parto e interpretación oportuna de las demoras en la fase latente

Abstract

Introduction: Labor is a physiological process of a woman of childbearing age, however, not all pregnancies end in a normal birth, as complications may exist. Labor is divided into two periods, the first consists of uterine changes through contractions and the second is the expulsion of the product. Friedman was the first to graphically represent the process of labor by subdividing this process into latent phase and active phase. Objective: To describe the models of the labor curve proposed by the main researchers of the subject, through the review of scientific articles, in order to understand the factors that allow to predict in time an anomaly in labor. Methods and Materials: A non-experimental analytical investigation was carried out, with inductive deductive method, by collecting information from several scientific articles found on servers such as Science Direct, Google Academic, Pubmed, where articles from the last 5 years were obtained, and information of the original articles of the time to describe the antecedent. Result: 25 scientific articles were analyzed, highlighting the evolution of the graphic representation of labor. Labor was defined as a physiological process, which begins with uterine contractions and concludes with the expulsion of the fetus. Conclusion: The presence of several postulates against Friedman's study was due precisely to the differences presented in the sample population.
