简要总结
Through many years, the standard care has been to use continuous sedation of critically ill patients during mechanical ventilation. However, preliminary randomised clinical trials indicate that it is beneficial to reduce the sedation level in these patients. The NONSEDA trial is an investigator-initiated, randomised, clinical, parallel-group, multinational, superiority trial designed to include 700 patients from at least six ICUs in Denmark, Norway and Sweden, comparing no sedation with sedation and a daily wake-up trial during mechanical ventilation. This is a substudy of the NONSEDA trial, concerning 250 patients included at trialsite Kolding, Denmark. The aim of the substudy is to assess the effects of no sedation on delirium during admission and cognitive function after discharge from ICU.
Our hypothesis is that critically ill patients who are not sedated during mechanical ventilation will have better cognitive function after discharge.

结局指标
主要结局
Cognitive function
时间窗: 3 months after discharge from ICU
Cognitive t-score, in percentage, difference between the two groups. The t-score for each patient will be diagnosed by the neuropsycologist at a personal interview and use of following tests: * Span of numbers * Coding test * Trailmaking A+B * Rey auditory verbal learning test (immediate, recall) * Rey-Ostherrieth complex figure test (immediate, recall, recognition) * Word finding test (S-word, animals) * Stroop test (congruent+incongruent)
次要结局
- Attention/concentration(3 months after discharge from ICU)
- Learning/memory(3 months after discharge from ICU)
- Executive dysfunction(3 months after discharge from ICU)
- Agitated delirium(3 months after discharge from ICU)
- Mental pace(3 months after discharge from ICU)
- Hypoactive delirium(3 months after discharge from ICU)
