    The study involved 65 pediatric patients with congenital heart disease undergoing corrective surgery with cardiopulmonary bypass.

  • 2

    Postoperative delirium occurred in 47.7% of patients, with significantly lower cerebral oxygen saturation levels observed in the delirium group.

  • 3

    Multivariate logistic regression indicated that lower early postoperative cerebral oxygen saturation independently predicted the risk of delirium.

  • 4

    Longitudinal analysis revealed consistently lower cerebral oxygen saturation levels in the delirium group at multiple postoperative time points.

  • 5

    The study utilized linear mixed-effects models to characterize the dynamics of cerebral oxygen saturation and its association with postoperative delirium.
