Objective:
Pulse oximetry screening (POS) is an effective tool to detect critical congenital heart disease (CCHD) in asymptomatic term infants, but its value in the neonatal intensive care unit (NICU) requires further clarification.
Study Design:
A retrospective review of 1005 babies without previously diagnosed CCHD admitted to a level III NICU was performed to assess the risk for missed CCHD and performance of POS.
Result:
Of the 1005 NICU patients, 812 had documented POS and none failed POS. In 812 patients, 547 had delayed POS because of the use of supplemental oxygen. In 259/812 patients, POS was delayed until the baby was >2 weeks old. CCHD was excluded by echocardiography, irrespective of POS, in 287/1005 patients.
Conclusion:
POS can be performed in the NICU with minimal adverse effects. However, in many NICU patients CCHD is confirmed or excluded before POS, and POS will frequently be performed after CCHD would have been expected to become symptomatic.
