Agitation during anaesthetic emergence: An observational study of adult cardiac surgery patients in two Australian intensive care units.

Background: Anaesthetic emergence agitation among adult patients being recovered after open cardiac and/or thoracic aorta surgery has not been described.

Objectives: The objective of this study was to characterise emergence agitation in terms of incidence, clinical features, and consequences in a cohort of cardiac surgery patients being recovered in the intensive care unit (ICU).

Methods: A prospective, observational pilot study was implemented.

Prevalence of illicit substance use among patients presenting to the emergency department with acute behavioural disturbance: Rapid point-of-care saliva screening.

Objective: To determine the prevalence of illicit substance use among patients presenting to one ED with acute behavioural disturbance using point-of-care saliva testing.

Methods: A prospective observational study was conducted. Acute behavioural disturbance was defined as any episode requiring a security response for unarmed threat (Code Grey).
