Evaluation of critical congenital heart defects screening using pulse oximetry in the neonatal intensive care unit.

OBJECTIVE: To evaluate the implementation of early screening for critical congenital heart defects (CCHDs) in the neonatal intensive care unit (NICU) and potential exclusion of sub-populations from universal screening. STUDY DESIGN: Prospective evaluation of CCHD screening at multiple time intervals was conducted in 21 NICUs across five states (n=4556 infants). RESULTS: Of the 4120 infants with complete screens, 92% did not have prenatal CHD diagnosis or echocardiography before screening, 72% were not receiving oxygen at 24 to 48 h and 56% were born ⩾2500 g. Thirty-seven infants failed screening (0.9%); none with an unsuspected CCHD. False positive rates were low for infants not receiving oxygen (0.5%) and those screened after weaning (0.6%), yet higher among infants born at <28 weeks (3.8%). Unnecessary echocardiograms were minimal (0.2%). CONCLUSION: Given the majority of NICU infants were ⩾2500 g, not on oxygen and not preidentified for CCHD, systematic screening at 24 to 48 h may be of benefit for early detection of CCHD with minimal burden.

Congenital nephrotic syndrome presenting with cerebral venous thrombosis, hypocalcemia, and seizures in the neonatal period.

Congenital nephrotic syndrome, a rare form of nephrosis, presents during the first year of life. We describe the case of a patient seen on the fifth day of life with seizures, hypocalcemia, hypothyroidism, and cerebral deep venous thromboses. Whereas these are generally long-term complications of this disorder, they may also be the presenting features in the neonatal period.
