Summary
Delirium is common in the elderly after hip fracture surgery, and is associated with worse outcomes. The investigators hypothesize that, for elderly patients after hip fracture surgery, dexmedetomidine supplemented analgesia can reduce the incidence of delirium and improve the long-term outcomes.
