CRP and delirium: Patients who presented delirium had more comorbidities, were frailerand had higher severity of illness scores (as expressed by a higher CCI, m-FI, SOFAand SAPS 3, respectively), and had higher C-reactive protein - CRP (9.72mg/dL [5.26- 17.20] versus 6.90mg/dL [3.70 - 13.95]; p = 0.048] at admission.The use of sedative and neuromuscular blockage was more frequent in patients withdelirium: midazolam (37.6% versus 15%; p <0.001), fentanyl (42.5% versus 22%; p < 0.001), neuromuscularblockage (9.9% versus 7.9%; p = 0.29) and dexamethasone (47.5%versus 14.8%, p < 0.001) (Table 1).
