The prevalence of agitation among emergency department (ED) patients is increasing. Physical restraints are routinely used to prevent self-harm and to protect staff, but are associated with serious safety risks. To date, characterization of physical restraint use in the emergency setting has been limited. We thus aim to describe restraint patterns in the general ED to guide future investigation in the management of behavioral disorders. ⋯ Our data found strong association of alcohol or drug use with physical restraints and identified a unique elderly population with behavioral disturbances in the ED. Further characterization of causal links and safer practices to manage agitation for these vulnerable populations are needed.

A 22-year-old man with a history of intravenous methamphetamine use presented with severe headache for 5 days, was afebrile, and had nuchal rigidity. Computed tomography and magnetic resonance imaging results were interpreted as revealing acute subarachnoid hemorrhage. ⋯ The false-positive image mimicking blood was potentially a result of an extremely high protein concentration present in the cerebrospinal fluid, provoked by an intense inflammatory reaction leading to disruption of the blood-brain barrier. Pyogenic meningitis is one of the causes of pseudosubarachnoid hemorrhage, or a false diagnosis of subarachnoid hemorrhage, when one does not actually exist.
