Clinical Features
- Delirium
- Disconnected from the environment
- Hyperdynamic vital signs
- Febrile
Differential Diagnosis
Altered mental status
Diffuse brain dysfunction
- Hypoxic encephalopathy
- Acute toxic-metabolic encephalopathy (Delirium)
- Hypoglycemia
- Hyperosmolar state (e.g., hyperglycemia)
- Electrolyte Abnormalities (hypernatremia or hyponatremia, hypercalcemia)
- Organ system failure
- Hepatic Encephalopathy
- Uremia/Renal Failure
- Endocrine (Addison's disease, Cushing syndrome, hypothyroidism, myxedema coma, thyroid storm)
- Hypoxia
- CO2 narcosis
- Hypertensive Encephalopathy
- Toxins
- TTP / Thrombotic thrombocytopenic purpura
- Alcohol withdrawal
- Drug reactions (NMS, Serotonin Syndrome)
- Environmental causes
- Deficiency state
- Wernicke encephalopathy
- Subacute Combined Degeneration of Spinal Cord (B12 deficiency)
- Vitamin D Deficiency
- Zinc Deficiency
- Sepsis
- Osmotic demyelination syndrome (central pontine myelinolysis)
- Limbic encephalitis
Primary CNS disease or trauma
- Direct CNS trauma
- Diffuse axonal injury
- Subdural/epidural hematoma
- Vascular disease
- SAH
- Stroke
- Hemispheric, brainstem
- CNS infections
- Neoplasms
- Paraneoplastic Limbic encephalitis
- Malignant Meningitis
- Pancreatic Insulinoma
- Seizures
- Nonconvulsive status epilepticus
- Postictal state
- Dementia
Psychiatric
General Psychiatric
- Organic causes
- Psychiatric causes
Diagnosis
Management
- Goal = sleepy, but arousable w/ HR <110
- Diazepam
- Long duration of action, max effect within 5min
- Start 10mg IV
- Redose q5min after observing effect
- Can double subsequent doses until achieve goal
- Propofol
- Consider intubation + propofol drip if benzo-nonresponsive
- Thiamine 100mg
Special Situations
- The propylene glycol diluent in lorazepam, phenobarbital and diazepam, may induce a hyperosmolar anion gap metabolic acidosis if given as a drip in high doses ≥ 48hrs.[1] Consider alternatives such as propofol or dexmedetomidine if patients need long term sedation for Delirum Tremens
