Abstract

Evoked potentials are sensitive prognostic tools in young infants at risk for developmental disability. The objective of this prospective study was to determine whether infants with congenital heart defects demonstrate evoked potential abnormalities prior to or following open heart surgery, and to examine the association between these abnormalities and developmental status 1 year following surgery. A consecutive series of newborns (less than 1 month old) and infants (1 month to 2 years old) were recruited. Somatosensory and brain stem auditory evoked potentials were carried out before or after cardiac surgery, or both. One year later, neurologic examination and standardized measures of motor performance and functional independence were carried out. Twenty-seven newborns and 31 infants underwent perioperative somatosensory evoked potential recordings. Results indicate that perioperative somatosensory evoked potential abnormalities were common in newborns (41%) but not in infants (13%) with congenital heart defects. Brainstem conduction times were within normal limits in all subjects; however, 32% presented with mild elevations in hearing thresholds. All newborns with abnormal somatosensory evoked potentials had abnormal neurologic examinations both perioperatively and again 1 year after open heart surgery. Moreover, standardized developmental assessments 1 year following surgery indicate that all newborns with somatosensory evoked potential abnormalities had developmental deficits in one or more domains. Somatosensory evoked potential abnormalities in the perioperative period are common in newborns with congenital heart defects, and are strongly predictive of persistent developmental delay later.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
