Sedation Efficacy of Dexmedetomidine Versus Midazolam in Critically Ill Ventilated Children

Mechanically Ventilated, Critically Ill Children

There is a significant lack of adequately powered randomized clinical trial (RCT) data to determine the comparative safety and effectiveness of sedative treatments in pediatric patients. In many centres the standard of care for sedation in pediatric critical care unit (PCCU) patients includes the use of benzodiazepines despite the known negative effects of increased patient agitation and delirium, which can contribute to longer PCCU and hospital length of stay (LOS). The use of an alternative sedative, dexmedetomidine may reduce negative effects in this population. As such, the investigators plan to conduct a well designed comparative RCT to determine the most effective and safest sedative in this vulnerable population utilizing clinical assessments of sedation levels and delirium instance, electroencephalography (EEG) analysis and patient important outcomes.
