Background
- Also known as agitated delirium
- Controversial diagnosis, not recognized by DSM 4/5 or ICD 9/10
- Recognized by ACEP in 2009[1]
- Agitation, aggression, acute distress, often in pre-hospital setting including police custody[2]
- Associate with hyperthermia, drug use and sometimes death[2]
Clinical Features[1]
- Triad of delirium, psychomotor agitation and physiological excitation
- Associated with drug use: cocaine (#1), methamphetamine, alcohol, PCP, LSD
- Associated with mental health disease
- Typically male, mean age 30's
- Violent, combative, belligerent, bizarre behavior
- Resistant to physical restraint, superhuman strength
- Associated with cardiopulmonary arrest
Differential Diagnosis
Evaluation
- Typical clinical features associated with
- Tachycardia
- Tachypnea
- Hyperthermia
- Acidosis
- Rhabdomyolysis
Management
Supportive care
- Evaluation for reversible clinical and lab abnormalities
- Hyperthermia: Remove clothing, misting/airflow, ice packs , cold IV fluids
- Acidosis: IV fluids; bicarb controversial
- Rhabdomyolysis: IV fluids
- Hyperkalemia
Agitation Reduction
- Prioritize chemical sedation although some physical restraint is always required
- Benzodiazepines, Neuroleptics
- Ketamine use increasingly described[3] but may be related with increased side effects such as intubation when used at max IM dosing[4]
- 4-5mg/kg IM
- 1-2mg/kg IV
- Consider IV olanzapine 2.5-5mg IV q5-10min to max dose of 20mg
- In place of IV haloperidol, which is approximately half as potent (~5-10mg haloperidol = ~2.5-5mg olanzapine)
- May be safer in patients with prolonged QTc or those too agitated to obtain ECG
- IV olanzapine may be as safe or safer than IM, with faster onset
Disposition
- Based on severity of clinical presentation and response to treatment
