Postoperative Delirium: A Literature Review of Management in Intensive Care Unit

Abstract

Perioperative delirium is a wide-ranging problem that directly affects primary clinical results. The anesthesiologist must understand how to define and diagnose delirium, identify patients at high risk of delirium, identify predisposing factors to adjust the care plan appropriately, and manage delirium in the acute postoperative period. Delirium is an organ dysfunction in critically ill patients, independently associated with improved morbidity. Research on delirium in hospitalized patients (including critically ill patients) has increased exponentially in the last decade. This study emphasizes the need for a mechanistic explanation of delirium to help advance the research that ultimately leads to its prevention and treatment. In this study, multinational and multidisciplinary clinicians, and researchers from the fields of critical care medicine, psychiatry, anesthesiology, neurology, and pharmacy sought to collaborate in the management of delirium in the intensive care unit (ICU).
