The most commonly used adjunct techniques in the different phases of analgesia and sedation. The values were tested with the χ² test (P < 0.05) and multiple differences with the Bonferroni–Holm multiple test procedure. (Clonidine: less than 24 hours versus more than 72 hours, less than 24 hours versus weaning and 24–72 hours versus weaning, all P < 0.01; 24 hours versus 24–72 hours, P = 0.23; 24–72 hours versus more than 72 hours, P < 0.017; more than 72 hours versus weaning, P = 0.067. Ketamine (S): less than 24 hours versus 24–72 hours, less than 24 hours versus more than 72 hours, 24–72 hours versus weaning and more than 72 hours versus weaning, all P < 0.0001; less than 24 hours versus weaning, P = 0.22; 24–72 hours versus more than 72 hours, P = 0.087.)
