2011, Article / Letter to editor (Critical Care, vol. 15, iss. 6, (2011), pp. R297)Delirium occurs frequently in critically ill patients and is associated with disease severity and infection. Although several pathways for delirium have been described, biomarkers associated with delirium in intensive care unit (ICU) patients is not well studied. We examined plasma biomarkers in delirious and nondelirious patients and the role of these biomarkers on long-term cognitive function.
2010, Article / Letter to editor (Intensive Care Medicine, vol. 2010, iss. 36, (2010), pp. suppl.-2 s221)Delirium occurs frequently in critically ill patients, and especially in severely ill and in infectious patients. Although several causal pathways for delirium have been described, the role of biomarkers in ICU patients is unknown. We investigated potential differences in various serum biomarkers between delirious and non-delirious ICU patients with and without an infection.
