MATERIALES Y MÉTODOS:  Estudio transversal llevado a cabo en el Hospital General de Zona 20 La Margarita, Puebla, Pue. Se incluyeron pacientes embarazadas con ultrasonido del primer trimestre practicado por un médico radiólogo y recién nacidos vivos evaluados con la escala Capurro por un solo pediatra. Se aplicaron las técnicas de estadística descriptiva e inferencial mediante rho de Spearman; los valores se consideraron estadísticamente significativos con un valor de p &#8804; 0.05.  RESULTADOS:  Se estudiaron 341 pacientes y se obtuvo una correlación positiva alta (r = 0.886), estadísticamente significativa (p = 0.000), entre el ultrasonido del primer trimestre traspolado al nacimiento y la calificación de Capurro otorgada por el pediatra.  CONCLUSIONES:  Existe correlación entre las semanas de gestación determinadas mediante el ultrasonido del primer trimestre y las obtenidas con la escala de Capurro.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  OBJECTIVE: To determine the correlation between first trimester ultrasound and the Capurro scale for neonatal gestational weeks.  MATERIALS AND METHODS:  Longitudinal study carried out at the Hospital General de Zona 20 La Margarita, Puebla, Pue. Pregnant patients with a first trimester ultrasound performed by a radiologist and live newborns evaluated by a single paediatrician using the Capurro scale were included. Descriptive and inferential statistical techniques were applied using Spearman&#8217;s Rho; values were considered statistically significant with a value &#8804; 0.05.  RESULTS:  341 patients were examined by Spearman&#8217;s Rho correlation coefficient and a high positive correlation (r = 0.886), statistically significant (p = 0.000), was obtained between the first trimester ultrasound transposed to birth and the Capurro score given by the paediatrician.  CONCLUSIONS:  there is a correlation between the weeks of gestation determined by first trimester ultrasound and those obtained with the Capurro scale.]]></p></abstract>
