Title: Substudy of the NONSEDA Trial (NCT01967680): Non-sedation Versus Sedation With a Daily Wake-up Trial in Critically Ill Patients Receiving Me-chanical Ventilation - Effects on Cognitive Function
Brief 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.
