RESUMO
OBJECTIVE: Assessment of neurobehavior and visual function of newborns with congenital heart disease during the post-operative period to identify infants at risk of neurodevelopmental and visual impairment. STUDY DESIGN: Prospective study that included 45 newborns who underwent cardiac surgery. Newborn Behavioral Observations test (NBO) and "ML Battery of Optotypes" were used for assessment. RESULTS: The median NBO global score was 2.4 [2.1-2.6]. Total days of oral morphine [p = 0.005] and total days of sedation [p = 0.009] were strongly related to abnormal evaluations. Time of cerebral regional oxygen saturation (CrSO2) under 40% during surgery and increased lactate were related to abnormal motor evaluation. Only 14.5% of patients presented pathological results in visual evaluation. CONCLUSIONS: We have demonstrated alterations in attention, autonomic, motor, and oral motor function. Duration of sedative medication, time of CrSO2 under 40% during surgery, and increased lactate are the most important risk factors. No significant visual impairment was detected.
