The Effect of Clonidine-enhanced Sedation on Delirium in Ventilated Critically Ill Patients

NCT01876355 · Status: UNKNOWN · Phase: PHASE3 · Type: INTERVENTIONAL · Enrollment: 115

Last updated 2023-02-15

No results posted yet for this study

Summary

Rationale: Delirium is highly prevalent in the ICU. GABA-ergic anaesthetics may provoke delirium. Alpha-2-adrenergic agonists may lead to a reduction of the total amount of GABA-ergic anaesthetics and reduction of delirium. There are no large studies proving that this therapy is effective and safe.

Objective: The objective of this study is to compare the effect of clonidine with placebo on the occurrence and duration of delirium in mechanically ventilated ICU patients.

Study design: Prospective randomised double-blind placebo controlled intervention study in 115 patients.

Study population: All patients \>18 years old, intubated mechanically ventilated and sedated at inclusion.

Intervention: Clonidine infusion of 0,25 mcg/kg/h added to the standard sedation regimen. Comparison: NaCl 0,9 % infusion as placebo.

Main study parameters/endpoints: The main study parameter is the total number of awake and delirium-free observation periods the first 7 days after randomisation. An observation period is a nursing shift of 8 hours.

Conditions

  • Delirium

Interventions

DRUG

Clonidine

o The concentration of clonidine in the solution is 12.5 µg/ml. Continuous iv infusion of 0.02 ml/kg/h results in a dosage of 0.25 µg/kg/h. The maximum dosage achieved is 25 µg/h. The total amount of clonidine given to a person with a body weight 100 kg or more will be 600 µg a day. Since the doses chosen are in the low range, there will be no dosage adjustment for renal- or liver failure.

DRUG

SodiumChloride

Placebo. Pharmaceutical form: Injection. Route of administration: Intravenous use.
