ClinConnect Summary

The PREVENT AGITATION Trial II is a clinical study aimed at understanding how effective and safe a medication called clonidine is in preventing emergence agitation in young children. Emergence agitation is when a child becomes confused, upset, or restless right after waking up from anesthesia, which can be quite distressing for both the child and their family. This trial focuses on children aged 3 to 12 months who are scheduled to undergo surgery with general anesthesia.

To participate, children must be healthy enough for surgery, and their parents or guardians need to provide written consent. During the study, some children will receive clonidine while others will receive a placebo (a treatment that looks the same but has no active medication) to help researchers compare the effects. Families can expect to be closely monitored for safety and effectiveness throughout the trial. It’s important to know that certain medical conditions may exclude a child from participating, such as serious heart or lung problems, or if the child has a history of allergic reactions to medications.
