Multiple causes can trigger delirium occurence, and it has been hypothesised that sleep disturbances can be one of them. Dexmedetomidine may be effective in reducing delirium. The aim of this study was to demonstrate preoperative dexmedetomidine nasal spray in cardiac surgery patients can reduce postoperative delirium by improving preoperative sleep.",[27,28],"Postoperative Delirium","Preoperative Sleep Disorder",[30,31,32,33],"postoperative delirium","preoperative sleep disorder","dexmedetomidine","cardiopulmonary coupling","RECRUITING","2026-08-02",{"date":37,"type":38},"2026-08-05","ACTUAL",{"date":40,"type":38},"2025-03-03",{"date":42,"type":21},"2027-03-30",{"name":44,"class":45},"Xijing Hospital","OTHER"]
