Validez entre la cervicometría determinada por ultrasonografía y el parto pretérmino en embarazadas atendidas en el Hospital José Carrasco Arteaga. Cuenca, 2018 – 2019.

Abstract

Background: Preterm birth is one of the main causes of neonatal morbidity and mortality. Cervical length measured by ultrasonography is a tool that could predict preterm birth. Objective: to establish the validity between cervical length measured by ultrasonography and preterm birth in pregnant women treated at the José Carrasco Arteaga Hospital, period 2018-2019. Methodology: observational, retrospective study, diagnostic test validation. We reviewed 400 medical records of pregnant women whose delivery was attended at the José Carrasco Arteaga Hospital during the period from January 2018 to December 2019 and who have an ultrasound with a cervical length report between 22 to 36 weeks of gestation. The information was collected through a data collection form. The analysis was performed in the SPSS 15.0 program. Sensitivity, specificity, positive predictive value, negative predictive value, and ROC curve of ultrasonographic cervical length were determined. Results: the prevalence of preterm birth was 31%, 23.3% were classified as late preterm, followed by 4.3 %, 1.8%, and 1.8% as moderate, very preterm, and extreme preterm infants, respectively. According to the measurement of the cervical canal, 88.3% were categorized as low risk of peterm birth, however, 8.8% and 3% were considered as moderate and high risk. Cervical length measured by ultrasonography sensitivity was 32.61%, specificity 47.58%, positive and negative predictive value 58.06% and 24.08% respectively; the area under the curve was 0.63, without showing predictive capacity of preterm birth.
