In critically ill, mechanically ventilated patients, daily interruption of sedation has been shown to reduce the time on ventilation and the length of stay in the intensive care unit (ICU).

Data on whether a plan of no sedation, as compared with a plan of light sedation, has an effect on mortality are lacking.

In a multicenter, randomized, controlled trial, we assigned, in a 1:1 ratio, mechanically ventilated ICU patients to a plan of no sedation (nonsedation group) or to a plan of light sedation (i.e., to a level at which the patient was arousable, defined as a score of −2 to −3 on the Richmond Agitation and Sedation Scale [RASS], on which scores range from −5 [unresponsive] to +4 [combative]) (sedation group) with daily interruption.

The primary outcome was mortality at 90 days. Secondary outcomes were the number of major thromboembolic events, the number of days free from coma or delirium, acute kidney injury according to severity, the number of ICU-free days, and the number of ventilator-free days.

Between-group differences were calculated as the value in the nonsedation group minus the value in the sedation group.
