Long term use of opioids and benzodiazepines are associated with important untoward effects. The α2 adrenergic agonist clonidine has sedative effects. Our goal was to study clonidine addition to total doses of fentanyl and midazolam and duration of ventilation in pediatric ICU (PICU). This randomized, double-blind, and placebo-controlled trial was conducted in PICU of Mofid Children Hospital. Hundred children aged from 2 to 15 years were randomized in 1:1 ratio to receive 5 μg/kg oral clonidine every 6 h or placebo plus 1-5 µg/kg/hr IV fentanyl and 0.05- 0.1 mg/kg/hr IV midazolam. Daily use of fentanyl and midazolam were measured. Ramsay sedation score was used for evaluation of sedation. A total of 96 patients were studied. The patients in placebo group received more midazolam and fentanyl compared with the patients in intervention group. Mean total dose of midazolam was 4.3 ± 2.2 mg in the placebo group and 2.7 ± 2.9 mg in the intervention group (<0.05). Mean total dose of fentanyl was 34.4 ± 23.1 µg in the placebo group and 18.9 ± 10 µg in the intervention group (<0.01). No significant differences were observed in duration of ventilation and length of PICU stay. No case of severe adverse effects was seen. This trial showed a reduction in total doses of midazolam and fentanyl given in ventilated children who were administered clonidine as add-on therapy. Clonidine addition had no effect on duration of mechanical ventilation.
