Dexmedetomidine was associated with the decreased postoperative fentanyl consumption, NVAS scores, and a decreased incidence of delirium. These findings may be beneficial for managing sedation protocols in adolescents who have undergone scoliosis surgery.

The baseline BIS value was lower in patients with cognitive impairment than in those with normal cognitive function. The former received less propofol during induction and eye opening time was longer. On the basis of our findings from the recovery period, we suggest that the recommended target BIS value for adequate anaesthesia in the general population is inappropriate for patients with cognitive impairment.
