Long-term Follow-up of Dexmedetomidine-esketamine and tDCS for Neurocognitive Complications After Surgery

Abstract

Neurocognitive complications, mainly delirium and neurocognitive disorders, are common cerebral complications in older patients after surgery and associated with worse long-term outcomes. An ongoing 2×2 factorial trial conducted by the investigators plan to test the effects of perioperative dexmedetomidine-esketamine combination and transcranial direct current stimulation (tDCS) on postoperative neurocognitive complications in older patients. This long-term follow-up of the ongoing trial aims to investigate the effects of perioperative dexmedetomidine-esketamine combination and tDCS on long-term outcomes in older patients after noncardiac surgery.
