Características ecográficas del saco gestacional como predictor de aborto. Hospital José Carrasco Arteaga. Cuenca, 2019-2020

Abstract

Background: obstetric ultrasound is the study of choice to identify premature pregnancy failure. The most used criteria are: irregularities of the gestational sac, absence of cardiac activity for a certain crane-caudal length and absence of a visible embryo for a certain mean diameter of the gestational sac. Objective: to determine the characteristics of the gestational sac as a predictor of abortion in the ultrasounds performed at the José Carrasco Arteaga Hospital. Cuenca, Ecuador 2019-2020 Methodology: a cross-sectional analytical study was carried out to determine the ultrasound characteristics of the gestational sac as a predictor of abortion. The universe consisted of 810 women who underwent obstetric transvaginal ultrasound at the José Carrasco Arteaga hospital 2019-2020. The sample size was calculated with the EPIDAT 3.6 program, with the following criteria: prevalence 26%, precision 5%, confidence level 95%, obtaining a sample of 218 women, personal identification data was not taken into account as name and identity document. For the development of this research, an informed consent form was provided. Results: the prevalence of abortion was 31.3%, in pregnant women between 4 and 12 weeks, with preponderant ages between 20 and 34 years, with a mean of 30.5 years, the ultrasound indicator showed a greater relationship of the loss of pregnancy is the absence of an embryo with a diameter of 36.4 mm. Conclusions: it was concluded that the characteristics of the gestational sac according to Nyberg are significantly associated with first trimester abortion; the double decidual reaction and the implantation of the gestational sac double the threat of abortion, in addition, the double decidual reaction has a great predictive capacity.
