Q

Delirium

A

Delirium can be the only finding of an acute medical condition in older demented individuals. Use of psychotropic medications as a first line therapy for behavioral problems is not recommended.
Focused history, PE and basic laboratory work-up should be performed early in the initial evaluation of delirium in any patient.
Psychical and chemical restraints should be used judiciously in a combative and disruptive patient. These help prevent injuries and falls, and allow for the continuation of medical therapy. Always give haloperidol (antipsychotics) before you apply restraints.
