NCT02948374

Brief Summary

Critical care patients are at a high risk of developing delirium and impaired cognitive function 3 and 12 months after their ICU stay. In this study the aim is to try to elucidate the pathophysiology behind delirium in the ICU and subsequent development of cognitive dysfunction in ICU survivors. Biomarkers in cerebrospinal fluid (CSF) will be analysed in patients with and without delirium in the ICU. Samples will also be taken 3 and 12 months after the ICU-stay. CSF will also be obtained in healthy age- and sexmatched controls undergoing surgery.

Outcome Measures

Primary Outcomes (1)

  • Concentration of biomarkers for inflammation and structural damage in the cerebrospinal fluid in patient with or without delirium in the ICU

    Delirium in the ICU is assessed with the CAM-ICU test and by EEG in patients admitted to the ICU for respiratory failure or circulatory or septic chock

    At Baseline samples of CSF are taken in patients evaluated with CAM-ICU test and with EEG for the presence or absence of delirium

Secondary Outcomes (2)

  • Concentration of neuroinflammatory biomarkers and markers of neural damage in the cerebrospinal fluid in surviving patients with and without cognitive dysfunction 3 months after their ICU stay.

    Three months after the patients have left the intensive care unit samples of CSF will be taken in surviving patients in the Outcome 1 group above.

  • Concentration of neuroinflammatory biomarkers and markers of neural damage in the cerebrospinal fluid in surviving patients with and without cognitive dysfunction 12 months after their ICU stay.

    Twelve months after the patients have left the intensive care unit samples of CSF will be taken in surviving patients in the Outcome 1 group above.

Study Arms (2)

Delirium positive

Patients with a positive CAM-ICU test

Delirium negative

Patient without delirium determined with the CAM-ICU test
