The present study aimed to investigate the effect of the timing and dose of dexmedetomidine on postoperative delirium in elderly patients after laparoscopic major non-cardiac surgery. ⋯ The dose and timing of dexmedetomidine appeared to be important in preventing delirium. The reduced incidence and duration of delirium by dexmedetomidine was associated with reduced levels of IL-6 24 h after surgery.
