Sedation in critically ill patients

Abstract

Sedation in the intensive care unit (ICU) is a topic that has been frequently researched, and debate still exists as to what are the best sedative agents for critically ill patients. There is increasing interest in sleep and circadian rhythm disturbances in the ICU and how they may impact on outcomes. In addition to patient-related and ICU environmental factors that likely impact sleep and circadian rhythm in the ICU, sedative and analgesic medications may also play a role.
