Dexmedetomidine Supplemented Intravenous Analgesia in Elderly After Orthopedic Surgery

Summary

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