ABSTRACT To compare strategies with and without first-day of life pulse oximetry screening to detect critical congenital heart defects (CCHDs).
Population based study including all live born infants in Norway in 2005 and 2006 (n = 116 057). Postductal (foot) arterial oxygen saturation (SpO(2)) was measured in apparently healthy newborns after transferral to the nursery, with SpO(2) < 95% as cut-off point. Out of 57 959 live births in the hospitals performing pulse oximetry screening, 50 008 (86%) were screened.
A total of 136 CCHDs (1.2 per 1000) were diagnosed, 38 (28%) of these prenatally. Of the CCHDs detected after birth, 44/50 (88%) were detected before discharge in the population offered pulse oximetry screening (25 by pulse oximetry), compared to 37/48 (77%) in the non-screened population (p = 0.15). Median times for diagnosing CCHDs in-hospital before discharge were 6 and 16 h after birth respectively (p < 0.0001). In the screened population 6/50 (12%) CCHDs were missed and recognized after discharge because of symptoms. Two of the six missed cases failed the pulse oximetry screening, but were overlooked (echocardiography not performed before discharge). If these cases had been recognized, 4/50 (8%) would have been missed compared to 11/48 (23%) in the non-screened population (p = 0.05). Of the cases missed, 14/17 (82%) had left-sided obstructive lesions.
First-day of life pulse oximetry screening provides early in-hospital detection of CCHDs and may reduce the number missed and diagnosed after discharge.

    ABSTRACT: AimPulse oximetry screening of newborn infants increases early detection of critical congenital heart disease and minimises the risk of circulatory collapse before surgery. This study provides an update on the implementation of pulse oximetry screening in the Nordic countries and proposes standardised guidelines. MethodsA questionnaire exploring pulse oximetry screening, clinical examination routines and availability of echocardiography was distributed to all 157 delivery units in the Nordic countries in June 2013. ResultsWe received responses from 156 of the 157 delivery units, and 116 (74%) were using pulse oximetry screening by September 2013. Preductal and postductal screening were both used in 59 of 116 units (51%), with just postductal screening in 51 of 116 (44%) and just preductal screening alone in 6 of 116 (5%). Screening was performed before 24h in 105 of 116 units (91%). The implementation of screening was highest in Finland (29/30, 97%), Sweden (42/46, 91%) and Norway (43/48, 90%) and lowest in Denmark (2/24, 8%) and Iceland (0/8 units). Conclusion In Sweden, Norway and Finland, the implementation of pulse oximetry screening is currently the highest in the world and coverage will be close to 100% in 2014. We propose uniform Nordic guidelines using preductal and postductal screening before 24h of age.

    ABSTRACT: Congenital heart disease is the most common and serious type of infant birth defect. Pulse oximetry screening has been supported in the literature as a valuable tool to aid in the prompt detection of critical defects. Pulse oximetry is easily accessible, inexpensive, and noninvasive, and can be readily performed by clinical nurses at the infant's bedside, however it remains a technology that is underutilized in newborns. Nurses can be leaders in addressing the need to translate knowledge into practice to improve the morbidity and mortality rates in the newborn population.

    ABSTRACT: BACKGROUND: Delayed diagnosis of critical congenital heart disease (CCHD) in neonates increases morbidity and mortality. The use of pulse oximetry screening is recommended to increase detection of these conditions. The contribution of pulse oximetry in a tertiary-care birthing center may be different from at other sites. METHODS: We analyzed CCHD pulse oximetry screening for newborns >= 35 weeks' gestation born at Brigham and Women's Hospital and cared for in the well-infant nursery during 2013. We identified patients with prenatal diagnosis of CCHD. We also identified infants born at other medical centers who were transferred to Boston Children's Hospital for CCHD and determined if the condition was diagnosed prenatally. RESULTS: Of 6838 infants with complete pulse oximetry data, 6803 (99.5%) passed the first screening. One infant failed all 3 screenings and had the only echocardiogram prompted by screening that showed persistent pulmonary hypertension. There was 1 false-negative screening in an infant diagnosed with interrupted aortic arch. Of 112 infants born at Brigham and Women's Hospital with CCHD, 111 had a prenatal diagnosis, and none was initially diagnosed by pulse oximetry. Of 81 infants transferred to Boston Children's Hospital from other medical centers with CCHD, 35% were diagnosed prenatally. CONCLUSIONS: In our tertiary-care setting, pulse oximetry did not detect an infant with CCHD because of effective prenatal echocardiography screening. Pulse oximetry will detect more infants in settings with a lower prenatal diagnosis rate. Improving training in complete fetal echocardiography scans should also improve timely diagnosis of CCHD.
