Does hyperglycemia after infant cardiac surgery adversely impact neurodevelopmental outcome? Context: Hyperglycemia has been associated with worse outcome after traumatic brain injury and cardiac surgery in adults. It is not known whether postoperative hyperglycemia results in worse neurodevelopmental outcome after infant cardiac surgery. Secondary analysis of postoperative glucose levels was performed in infants younger than 6 months of age enrolled in a prospective study of genetic polymorphisms and neurodevelopmental outcomes who were undergoing repair of two-ventricle cardiac defects. Neurodevelopmental outcomes at 1 year of age were assessed with the Bayley Scales of Infant Development-II, yielding two indices: Mental Developmental Index and Psychomotor Developmental Index. Surgical repair was performed in 247 infants with 1 in-hospital and 3 late deaths. Neurodevelopmental evaluation was performed in 188 of 243 (77%) survivors. Glucose levels at cardiac intensive care unit admission and during the first 48 postoperative hours were available for 180 of 188 patients. Mean admission glucose was 328 +/- 106 mg/dL; maximum glucose was 340 +/- 109 mg/dL. At least one glucose was greater than 200 mg/dL in 160 of 180 patients, and 49 of 180 patients (27%) had a glucose greater than 400 mg/dL. Only 1 patient had a glucose less than 50 mg/dL. Female sex (p = 0.02), but no other patient or operative variable, was associated with higher glucose levels. Mean Mental Developmental Index and Psychomotor Developmental Index were 90.6 +/- 14.9 and 81.6 +/- 17.2, respectively. Hyperglycemia was not associated with lower Mental Developmental Index and Psychomotor Developmental Index scores for the entire cohort or for neonates alone.

Hyperglycemia is common early after infant cardiac surgery, but is not associated with worse neurodevelopmental outcome at 1 year of age. Final Decision: no
