Saturación pre y postductal en la detección precoz de cardiopatías congénitas en recién nacidos del Hospital José Carrasco Arteaga, julio 2017–junio 2018

Abstract

Objective: to determine the pre and postductal saturation to the early detection of congenital heart diseases in term newborns at José Carrasco Arteaga Hospital, july 2017–june 2018. Methodology: quantitative, descriptive and cross-sectional study at which pre and postductal saturation were measured in healthy term newborns admitted to the joint housing service, who met the screening criteria. The measurement was made between 24 to 48 hours of life. Newborns with positive screening underwent an echocardiogram to confirm critical congenital heart disease. Absolute and relative frequencies were used; measures of central tendency, dispersion and position. Results: 1262 newborns were screened. In Cuenca at 2550 meters amsl, preductal and postductal saturation in healthy term infants did not show a normal distribution; the median of the preductal was 95.9% (Interquartile range 2.1) and of the postductal 96.0% (Interquartile range 2.1). 18 (1.4%) cases were positive for the test. Echocardiogram confirmed 2 (0.001%) cases with acyanotic congenital heart defects, Persistent Arterial Duct and Interauricular Communication. Conclusions: critical congenital cardiopathies were not found, however, the measurement of preductal and postductal saturation from 24 to 48 hours of life allowed the early identification of congenital heart diseases that were confirmed by echocardiography.
