Adverse event data are presented as the number of patients with at least one adverse event related to sedation. Other adverse events are gas exchange deficiency, minor skin irritation caused by electrodes, hemodynamic instability, and unplanned extubation. Wilcoxon rank-sum test was used for days alive, log-rank test for ICU length of stay, and for the other data, values were estimated with Fisher’s exact test.
