Summary

Background: Every year 30,000 Danish patients are admitted to Intensive Care Units (ICU), accounting for 2-3% of all patients in hospital and 30% of the yearly hospital expenditure. The mortality in the ICU is 12.7 % and the 30-day mortality is 21.2 % according to the national Danish Intensive Care Database. Through many years, the standard care has been to use continuous sedation of critically ill patients during me-chanical ventilation. However, recent research indicates that it is beneficial to reduce the sedation level in these patients. A randomised trial found that continuous sedation with a daily wake-up trial compared to continuous sedation reduced the time on me-chanical ventilation and the length of stay in the intensive care unit. Further, a ran-domised trial comparing continuous sedation with a daily wake-up trial to no sedation found that patients in the non-sedated group needed mechanical ventilation for a shorter time and had a shorter length of stay in the ICU and in the hospital. The trial also indicated a beneficial effect on mortality, however the trial was not a priori de-signed or powered with respect to mortality. No randomised trial has been published comparing sedation with no sedation, a priori powered to have all-cause mortality as primary outcome. Objective: To assess the benefits and harms of non-sedation versus sedation with a daily wake-up trial in critically ill patients in ICU. Design: 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. Inclusion criteria: Mechanically ventilated patients with expected duration of me-chanical ventilation \> 24 hours. Exclusion criteria: non-intubated patients, patients with severe head trauma, coma at admission or status epilepticus, patients treated with therapeutic hypothermia, patients with PaO2/FiO2\<9 where sedation might be necessary to ensure sufficient oxygenation or place the patient in prone position. Experimental intervention: Non-sedation supplemented with pain management during mechanical ventilation. Control intervention: Sedation with a daily wake-up trial. The primary hypothesis is that non-sedation compared to sedation and a daily wake-up trial will reduce mortality. The secondary hypotheses are that non-sedation compared to sedation and a daily wake-up trial will: * Reduce the incidence of a composite outcome of death, acute myocardial in-farction (AMI), stroke, pulmonary embolism and other thromboembolic events. * Reduce the number of organ failures. * Increase the days alive without mechanical ventilation. * Increase the days alive outside the ICU. * Increase the days alive outside the hospital. Outcomes: The primary outcome is all-cause mortality at 90 days. Secondary out-comes are time to death in the trial period, the frequency of the trombo-embolic com-plications, acute renal failure, days alive without mechanical ventilation, days alive outside the ICU and hospital. Explorative outcomes are mortality at 28 days, organ failure and coma-free, delirium-free days. Trial size: The investigators will include 700 participants (2 x 350) in order to detect or reject 25% relative risk reduction in mortality with a type I error risk of 5% and a type II error risk of 20% (power at 80%).
