VALUE OF PULSE OXIMETRY IN THE DIAGNOSIS OF CONGENITAL HEART DISEASE IN NEWBORNS IN THAI NGUYEN
Main Article Content
Abstract
Objectives: To evaluate the value of pulse oximetry in the diagnosis of congenital heart disease in newborns at Thai Nguyen National Hospital in 2023-2024. Subjects: 357 newborns came for examination and treatment at the Pediatric Center - Thai Nguyen National Hospital. Methods: Descriptive study. Results: The number of newborns with positive pulse oximetry results was 73/357 newborns, accounting for 20.4%. The number of newborns with congenital heart defects after Doppler echocardiography was 104/357 newborns, accounting for 29.1%. Among congenital heart defects, patent ductus arteriosus accounts for the highest rate of 55.7%. Pulse oximetry has the ability to diagnose congenital heart in newborns with sensitivity of 65.4%; specificity of 98%. Positive predictive value of the method was 93.1% and negative predictive value was 87.3%. Conclusions: Pulse oximetry is an effective screening and help to diagnose early of congenital disease in newborns with high specificity and moderate sensitivity.
