The use of sedation in terminally ill patients is intended to provide relief from refractory symptoms that are not controlled by other methods. These symptoms may include physical and psychological distress such as delirium, agitation, anxiety or terminal restlessness.
Palliative sedation therapy can vary in terms of the duration of sedation (intermittent or continuous sedation) and the level of sedation (mild, intermediate or deep sedation). Sedation is achieved by using drugs that are classed as sedatives and include benzodiazepines and antipsychotics.
