Alcohol withdrawal: documentation that holds up
"Alcohol withdrawal" is a diagnosis of exclusion with no confirmatory test — and the things it hides (head bleed, sepsis, Wernicke, metabolic catastrophe) are what kill. The defensible chart shows you treated the withdrawal aggressively and ruled out the mimics, with thiamine given and a disposition that respects the risk of delirium tremens.
01What's at stake
Severe withdrawal carries real mortality, and delirium tremens — which can appear 2–4 days after the last drink — is a medical emergency that, treated late, kills, but with timely care approaches 0% mortality. Two failures dominate: anchoring on "just withdrawal" while missing a subdural or sepsis, and under-dosing sedation out of an unfounded fear of respiratory depression.
02The timeline
- Early/minor (6–24h): tremor, anxiety, insomnia, nausea, autonomic signs (which beta-blockers can mask).
- Alcoholic hallucinosis: hallucinations (often tactile) with an intact sensorium.
- Withdrawal seizures (12–36h): usually brief and isolated; status is rare and should prompt a search for another cause.
- Delirium tremens (~24–72h, lasting days): withdrawal + altered mentation, fever, severe agitation — and it can be quiet, without florid agitation or autonomic surges.
03The dangerous mimics — don't anchor
- Occult head injury / subdural hematoma (falls). → CT head for AMS, seizure, trauma, delirium
- CNS infection (meningitis/encephalitis), sepsis. → infection workup
- Wernicke encephalopathy. → thiamine
- Hypoglycemia, electrolyte/metabolic derangement (Mg, K, PO₄), alcoholic ketoacidosis, hepatic encephalopathy. → labs
- Other ingestions / toxic alcohols; an elevated ethanol level does not exclude withdrawal. → broaden workup
Skip the typing
Work the case in the Alcohol Intoxication / Withdrawal Workup — it records glucose, the serial exam, CIWA, thiamine, head CT, and tox labs, and assembles an MDM that documents the mimics were excluded and withdrawal was treated.
04Assessment & treatment
- CIWA-Ar guides symptom-triggered dosing (not valid in the sedated/intubated — use RASS). The best predictor of severe withdrawal is a prior history of it.
- Symptom-triggered benzodiazepines, front-loaded — diazepam (fast, self-tapering) or lorazepam (preferred in severe liver disease); titrate to control. Patients need higher doses (down-regulated GABA receptors) — don't under-treat from respiratory fear.
- Phenobarbital is an effective alternative/adjunct under protocol; propofol for the intubated, refractory patient; dexmedetomidine/ketamine are adjuncts that don't treat the underlying pathophysiology.
- Antiseizure drugs (phenytoin) don't work for withdrawal seizures — use benzodiazepines/barbiturates.
- Thiamine (IV; 500 mg if any Wernicke sign — the full triad is rare), magnesium, fluids; give thiamine before dextrose but don't delay dextrose for hypoglycemia.
05What to document
06Where charts fail
- Attributing altered mental status to "withdrawal" without excluding subdural, sepsis, Wernicke, and metabolic causes.
- Using an elevated ethanol level to dismiss withdrawal.
- Under-dosing benzodiazepines out of unfounded respiratory-depression fear.
- Copying prior-admission dosing despite kindling (escalating needs).
- Skipping labs/thiamine, or discharging a confused "stable" DT patient to the floor instead of a monitored bed.
