Study summary

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.

Study arms

  • Experimental
    Non-sedation

    Non-sedation supplemented with pain management during mechanical ventilation.

    Other: Non-sedation

  • Active comparator
    Sedation

    Current gold standard: Sedation with a daily wake-up trial.

    Other: Control: Sedation

Interventions

  • OtherNon-sedation

    Patients are awake or have natural sleep during mechanical ventilation. Pain is treated with morphine iv.

  • OtherControl: Sedation

    Continuous iv-sedation (propofol first 48 hours, from then midazolam) to Ramsey 3-4 with a daily wake up attempt, where sedation is stopped until patient is awake.

What researchers measure

Primary outcomes

  1. Cognitive function

    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)

    Time frame: 3 months after discharge from ICU

Secondary outcomes

  1. Attention/concentration

    T-score in the two groups for the cognitive domaine attention/concentration

    Time frame: 3 months after discharge from ICU

  2. Learning/memory

    t-score in the two groups for the cognitive domaine: learning/memory

    Time frame: 3 months after discharge from ICU

  3. Executive dysfunction

    t-score in the two groups for the cognitive domaine: executive dysfunction

    Time frame: 3 months after discharge from ICU

  4. Mental pace

    t-score in the two groups for the cognitive domaine: mental pace

    Time frame: 3 months after discharge from ICU

  5. Hypoactive delirium

    Occurrence of hypoactive delirium (RASS ≤ 0, CAM-ICU positive) in each group related to cognitive function at follow up

    Time frame: 3 months after discharge from ICU

  6. Agitated delirium

    Occurrence of agitated delirium (RASS ≥ +2, CAM-ICU positive) in each group related to cognitive function at follow up

    Time frame: 3 months after discharge from ICU
