Does Intraoperative Clonidine Reduce Post Operative Agitation in Children?

Status Completed

Clinical Trial Summary

Clonidine is widely used off-label in children for several indications. Clonidine is used for treatment and/or prevention of postoperative agitation in children anaesthetised with Sevoflurane. The investigators don´t have solid evidence for the effect and the investigators don´t have data for characterization of the pharmacokinetic profile among age-groups for children 1-6 years.

In this study the investigators want to investigate if IV Clonidine administered at the end of surgery can prevent/reduce postoperative agitation. Secondary outcomes include measurements of postoperative pain relief and adverse effects, including a 30-day follow-up.

Clinical Trial Description

BACKGROUND:

Clonidine is widely used off-label in children for several indications such as treatment and/or prevention of postoperative agitation when anaesthetised with Sevoflurane. However, the current level of evidence in support of Clonidine treatment for postoperative agitation in children remains limited. In addition, the pharmacokinetic profile of intravenous Clonidine in children is not well characterized for age-groups.

METHODS/DESIGN:

In this prospective multicentre double-blinded randomized clinical trial, the investigators aim to investigate the impact of intravenous (IV) Clonidine administered at the end of surgery, on the incidence and degree of postoperative agitation. Children will be assigned to either the intervention or the placebo group. The allocation will be carried out centrally and stratified based on age and trial-site, with152 patients allocated to each group. In the intervention group, 3 micrograms per kg of IV clonidine is administered approximately 20 minutes before the expected completion of the surgery (as assessed by the surgeon). In the control group; Saline (placebo) is injected in equal quantity during surgery at the same time. The drugs are concealed in identical blinded ampoules.

The primary outcome is postoperative agitation measured on the Watcha scale. Secondary outcomes include measurements of postoperative pain relief and adverse effects, including 30-day follow-up.

Twenty of the patients age 1-2 years and twenty age >2 years, with a peripheral venous access in place, will be allocated to drug assay sampling; enabling a compartmental PK analysis based on age group, using non-linear mixed effects models. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
