Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are pediatric patients aged 3 to 12 months scheduled for general anesthesia with sevoflurane.

Probably not a fit

Patients with ASA classification greater than 2, those undergoing cardiac or neuro surgeries, or those with critical illnesses may not benefit from this study.

What this trial studies

This clinical trial investigates the efficacy and safety of a single dose of intraoperative clonidine in children aged 3 to 12 months undergoing general anesthesia with sevoflurane. It is a randomized, placebo-controlled study designed to assess the impact of clonidine on emergence agitation, a common postoperative complication characterized by behavioral disturbances. The trial will also evaluate the pharmacokinetics of clonidine in this pediatric population. Participants will be closely monitored for safety and effectiveness throughout the study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of emergence agitation in young children after anesthesia, improving their postoperative experience.

How similar studies have gone: Previous studies have shown promising results with clonidine in managing emergence agitation, suggesting that this approach may be effective.
