Prevention and Management of Delirium in the Intensive Care Unit

Delirium, a prevalent form of organ dysfunction afflicting critically ill adults, stands as a substantial contributor to both morbidity and mortality. Despite its ubiquity, the precise mechanisms underlying delirium remain unknown, likely influenced by multiple pathways that become perturbed during episodes of critical illness. Historically, the management of delirium in the intensive care unit (ICU) has posed significant challenges, primarily due to a limitted efficacy of pharmacological interventions. However, authors from Nashville, Tennessee, provide a concise depiction of the historical observations and prevailing practices in this matter. Notably, contemporary guidelines now discourage the routine use of haloperidol or atypical antipsychotics for the prevention or treatment of delirium in critically ill adults, despite their once-widespread acceptance as therapeutic modalities in 2002. Instead, pharmacological strategies for the management and prevention of delirium include the utilization of Dexmedetomidine, a medication that provide the regulation of the sleep-wake cycle and has sedative properties.
