Pulse oximetry could significantly enhance the early detection of critical congenital heart disease in neonatal intensive care units

چکیده
AIM Limited data have been available regarding critical congenital heart disease (CHD) screening in neonatal intensive care unit (NICUs). This study evaluated the feasibility of screening for CHD by adding pulse oximetry (POX) to clinical evaluation in a NICU in Shanghai, China. METHODS We screened 4128 eligible consecutive NICU admissions using POX plus clinical evaluation. Infants with positive screening results were then evaluated with echocardiography. Those with negative screening results were put under observation, and they also underwent echocardiography if their oxygen saturation fell below 95% on room air during hospitalisation. RESULTS This enhanced procedure detected 19 critical CHD cases, and seven of these diagnoses would have been delayed if POX had not been incorporated into the screening strategy. This means that the addition of POX increased the detection rate of critical CHD from 63.2 to 100%. The false-positive rate of critical CHD screening using POX plus clinical evaluation was higher in NICU patients with high morbidity rates. CONCLUSION When pulse oximetry screening was added to clinical evaluation, it increased the number of critical CHD cases that were detected in our NICU. This method could provide a useful screening protocol for critical CHD cases.

Screening for critical congenital heart disease (CCHD) was added to the United States Recommended Uniform Screening Panel in 2011. Since that time, CCHD screening with pulse oximetry has become nearly universal for newborns born in the United States. There are various algorithms in use. Although the goal of the screening program is to identify children who may have CCHD, most newborns who have ...

OBJECTIVE No reliable clinical markers of histologic chorioamnionitis (HCA), a major and often subclinical cause of prematurity leading to high neonatal morbidity and mortality, are available to date. Increasing evidence indicates myocardial dysfunctions in affected fetuses and newborns. We sought to assess the value of nonlinear dynamics from pulse oximetry signals in identifying affected newb...
