Implication of pulse oxymetry screening for detection of congenital heart defects.

چکیده
BACKGROUND In newborns congenital heart defects can take an asymptomatic course, causing a diagnostic gap in the routine examination. Therefore pulsoxymetric screening is under discussion, as it could close this diagnostic gap. PATIENTS AND METHODS Non-invasive postductal peripheral oxygen saturation assessment was carried out in 3 364 term neonates, 6-36 h of age, in 2008. In asymptomatic neonates with values > or = 95%, no further steps were applied. In those with values between 90% and 94% and no clinical abnormalities, a check-up was carried out 4-6 h later. Echocardiography was performed when the initial value was below 90% or persisted < 95 %. RESULTS A total of 18 (0.5%) abnormal pulse oximetry values requiring echocardiographic investigation were found in the 3 364 neonates examined. 9 congenital heart defects that had not been recognized prenatally were diagnosed. 4 of these children were also found to have anomalies at the clinical examination. Persistent fetal circulation was noted in 2 of the neonates.In addition neonatal infections has been detected in 7 newborns. 1 neonate with stenosis of the aortic isthmus and 1 with pulmonary stenosis were missed in the screening program, with pulse oximetry saturation levels >95%. These data represent a sensitivity of 82% and a specificity of 99.9%, with a positive predictive value of 50% and a negative predictive value of 99.9%. CONCLUSIONS Together with the clinical examination, pulse oximetry in neonates is a screening method that has high levels of sensitivity and specificity for early diagnosis of congenital heart defects. The risk-benefit profile may favour pulse oximetry to be standardized and universally used.

Introduction: Congenital heart disease is the most common congenital anomaly. About 50% of Neonates with congenital heart disease are asymptomatic in the first few days of life and are not diagnosed on initial examination. Pulse oximetry is a non-invasive method that can show the percentage of oxygen saturation in the blood and congenital heart disease. Methods: This was a descriptive cross-se...
