Recognizing Alcohol Withdrawal in the ED: From Tremors to Trouble

-Case-
A 54-year-old man presents to the ED with tremors, agitation, and nausea. He admits to heavy daily alcohol use but hasn’t had a drink in 2 days in an effort to quit. On exam, he’s tachycardic, diaphoretic, and mildly hypertensive. He keeps asking to leave but appears confused.

-Evaluation-
Alcohol withdrawal is a spectrum disorder that can range from mild symptoms to life-threatening delirium tremens (DTs). It generally begins 6-24 hours after the last drink in patients with significant – often daily – alcohol consumption.

  • Timeline of symptoms:
    • 6-12 hrs: tremors, anxiety, nausea, headache, insomnia
    • 12-24 hrs: hallucinations (visual, auditory, tactile)
    • 24-48 hrs: seizures (tonic-clonic, often multiple)
    • 48-96 hrs: delirium tremens (confusion, autonomic instability, hallucinations)
  • Key findings:
    • Tremors, diaphoresis, tachycardia, hypertension, anxiety
    • Seizures can occur early without warning!
    • Delirium and autonomic instability are late signs

Diagnosis:

  • Clinical diagnosis based on history and physical
  • CIWA scoring system is helpful in guiding benzodiazepine dosing, though not particularly useful in critically ill or nonverbal patients
  • Rule out other causes of agitation/confusion (electrolytes, infection, trauma, hepatic encephalopathy)

-Management-

  • Benzodiazepines are the mainstay (diazepam, lorazepam, or chlordiazepoxide)
    • Symptom-triggered therapy (based on CIWA) is preferred in stable patients
    • Fixed-schedule dosing or use escalating doses for severe withdrawal
  • Supportive care: IV fluids, thiamine (before glucose!), multivitamins, glucose, correction of electrolytes
  • Consider phenobarbital or propofol in refractory cases or ICU settings
  • Admit if high risk, significant symptoms, or comorbidities

-Fast Facts-

  • Alcohol withdrawal symptoms can progress quickly and unpredictably
  • Benzos are your first-line agents, and early aggressive treatment can prevent DT
  • Always give thiamine before glucose to prevent precipitating Wernicke’s encephalopathy

The next time someone is sweating, shaky, and irritable after a drinking binge, don’t underestimate the potential for rapid decompensation. Alcohol withdrawal is one of the few tox syndromes where benzos save lives. Get ahead of it before it gets ahead of you!
