However, it is not clear whether dexmedetomidine has preventive effect against delirium in the patients with high risk of postoperative delirium (POD) since no previous studies have clearly emphasized high-risk surgical patients.</p><p><strong>Method: </strong>In this single-center, double-blind, randomized controlled trial, we randomize 114 high risk POD patients defined by developed predictive scores and admitted to surgical intensive care units (SICUs) into 2 groups: nocturnal dexmedetomidine (9 pm – 6 am) and placebo. The outcomes were incidence of POD, delirium-free days, secondary delirium-related complications and concerned complications including hypotension and bradycardia. Other treatments apart from intervention are standardized. Intention to treat analysis is used to analyze all data.</p><p><strong>Hypothesis: </strong>We hypothesize that nocturnal dexmedetomidine giving to high-risk POD patients admitted to SICUs postoperatively would (1) reduce incidence of POD (2) improve delirium-free days (3) reduce secondary delirium-related complications (4) show no difference in hypotension and bradycardia between groups.</p><p><strong>Ethics and dissemination: </strong>The trial receives ethic approval from Siriraj Institutional Review Board. We plan to disseminate the results in peer-reviewed critical care medicine or anesthesiology-related journals, conferences nationally and internationally.</p><p><strong>Trial registration: </strong>TCTR20210217001</p> ER -
