ICU delirium are assessed by clinical nurses twice every day using Confusion Assessment Method for the ICU (CAM-ICU). Delirious patients are matched with patients according to their disease, gender and age range(±3 years). Stool samples for gene sequencing are collected within 24 hours after surgeries. Gut barrier function are studied with several serum biomarkers (endotoxin, etc.). Ecological analyses, regression models and mediation equation will be performed.
