Outcome Measures

Primary Outcomes (1)

  • Number of patients have postoperative delirium

    Assess postoperative delirium by using Confusion Assessment Method for intensive care unit (CAM-ICU) at recovery room and Confusion Assessment Method at inpatient ward.

    Participants will be followed during the duration of hospital stay, an expected avarage of two weeks.

Secondary Outcomes (2)

  • Number of patients with impaired cognitive function

    Up to 6 months

  • Time to recovery

    The end of surgery

Study Arms (2)

Bispectral index (BIS) group

EXPERIMENTAL

Bispectral index as measured by a BIS Processor is used to guide doses of anesthetic for maintaining the BIS values of 40-60

Device: Bispectral index, as measured by a BIS processor

Control group

NO INTERVENTION

Clinical signs is used to guide doses of anestheitics.

Interventions

Comparisons of incidence of postoperative delirium.
