Univariate analysis showed that pre-LT variables (Model for End Stage Liver Disease (MELD) score, hospital stay, hepatic encephalopathy, infection, white blood cell (WBC) count, lymphocyte count, abnormal potassium, lactulose use), intraoperative variables (red blood cell transfusion, remimazolam use, dexmedetomidine use) and post-LT variables (hypernatraemia, acute rejection, reoperation, basiliximab use, tacrolimus concentration) were associated with post-LT delirium. Multivariate logistic regression analysis revealed that MELD score at LT \u226522 [OR\u2009=\u20093.400, 95% CI:1.468\u20137.876, <jats:italic>p<\/jats:italic>\u2009=\u20090.004], pre-LT hepatic encephalopathy [OR\u2009=\u20093.224, 95% CI:1.664\u20136.244, <jats:italic>p<\/jats:italic>\u2009=\u20090.001], infection within 2\u2009months prior to LT [OR\u2009=\u20092.238, 95% CI:1.151\u20134.351, <jats:italic>p<\/jats:italic>\u2009=\u20090.018], acute rejection [OR\u2009=\u20092.974, 95% CI:1.322\u20136.690, <jats:italic>p<\/jats:italic>\u2009=\u20090.008], and reoperation [OR\u2009=\u200911.919, 95% CI:2.938\u201348.350, <jats:italic>p<\/jats:italic>\u2009=\u20090.001] were independent risk factors for post-LT delirium.
