Management of Alcohol Withdrawal Syndrome: Admitting Orders and Principles
Indications for Hospital Admission
Admit patients with alcohol withdrawal syndrome to inpatient care if they have any of the following: significant AWS symptoms, history of withdrawal seizures or delirium tremens, high levels of recent drinking, co-occurring serious medical or psychiatric illness, or failure of outpatient treatment. 1
Focused History
Obtain the following critical historical elements:
- Alcohol use pattern: Quantity, frequency, duration of heavy drinking, and timing of last drink (AWS typically begins 6-24 hours after cessation) 1
- Previous withdrawal history: Prior seizures, delirium tremens, or complicated withdrawals requiring hospitalization 1
- Comorbid conditions: Liver disease, head trauma, respiratory failure, psychiatric illness, polysubstance abuse 1, 2
- Current symptoms: Tremor, sweating, tachycardia, anxiety, agitation, hallucinations, confusion, nausea/vomiting 1
- Nutritional status: Signs of thiamine deficiency or Wernicke-Korsakoff syndrome 1, 2
Focused Physical Examination
Assess for the following specific findings:
- Vital signs: Tachycardia, hypertension, hyperthermia, tachypnea (autonomic hyperactivity) 1
- Neurological exam: Tremor (especially hands), hyperreflexia, altered mental status, disorientation, seizure activity 1
- Mental status: Agitation, hallucinations (visual, tactile, auditory), delirium, fluctuating consciousness 1
- Signs of complications: Dehydration, fever, signs of infection, gastrointestinal bleeding, pancreatitis, hepatic encephalopathy 1
- Stigmata of chronic liver disease: Jaundice, ascites, spider angiomata, hepatomegaly 1
- Nutritional deficiencies: Ophthalmoplegia, ataxia, confusion (Wernicke's triad) 1
Admitting Orders
1. Monitoring Orders
- Vital signs every 1-2 hours initially, then every 4 hours once stable 1
- CIWA-Ar scoring every 1-4 hours (score >8 indicates moderate AWS requiring treatment; score ≥15 indicates severe AWS) 1, 3
- Continuous telemetry for patients with severe symptoms or cardiac risk factors 1
- Seizure precautions 1
2. Laboratory Orders
- Complete blood count, comprehensive metabolic panel
- Liver function tests (AST, ALT, bilirubin, albumin)
- Magnesium, phosphate
- Blood alcohol level
- Toxicology screen (to identify polysubstance use)
- Consider ammonia if hepatic encephalopathy suspected 1, 2
3. Pharmacological Orders
Thiamine (MUST be given BEFORE any glucose-containing IV fluids)
- Thiamine 100-300 mg IV/IM daily for prevention of Wernicke encephalopathy 1, 3
- Continue for 4-12 weeks for prevention; 12-24 weeks if Wernicke encephalopathy present 1
- Critical caveat: Administering glucose before thiamine can precipitate acute Wernicke encephalopathy 1, 3
Benzodiazepines (First-Line Treatment)
For most patients (without liver failure):
- Diazepam 5-10 mg PO/IV/IM every 6-8 hours (long-acting, preferred for seizure prevention) 1, 4
- Alternative: Chlordiazepoxide 25-100 mg PO every 4-6 hours 1
For patients with liver failure, advanced age, respiratory failure, obesity, or recent head trauma:
- Lorazepam 1-4 mg PO/IV/IM every 4-8 hours (starting dose 6-12 mg/day divided) 1, 3
- Lorazepam is safer because it doesn't require hepatic oxidation 1, 5
Dosing strategy: Use symptom-triggered regimen based on CIWA-Ar scores rather than fixed-dose schedule to prevent drug accumulation 1
Taper: Begin tapering after resolution of withdrawal symptoms; limit total benzodiazepine treatment to 10-14 days maximum to avoid dependence 1, 3
Adjunctive Medications (Use Only When Indicated)
- Haloperidol 0.5-5 mg PO/IM every 8-12 hours: Only for agitation or psychotic symptoms (hallucinations) NOT controlled by benzodiazepines alone 1, 3
- Carbamazepine 200 mg PO every 6-8 hours: Alternative for seizure prevention if benzodiazepines contraindicated 1, 3
4. Supportive Care Orders
- IV fluids: Normal saline or lactated Ringer's for hydration (give thiamine FIRST) 1
- Electrolyte replacement: Magnesium sulfate, potassium, phosphate as needed 1
- Multivitamin supplementation 1
- Comfortable, quiet environment with minimal stimulation 1
- Aspiration precautions if altered mental status 1
5. Consultation Orders
- Psychiatry consultation for evaluation, acute AWS management, and long-term abstinence planning 1, 3
- Consider addiction medicine or hepatology if significant liver disease present 3
Critical Medications to AVOID
Never prescribe the following in patients with alcoholic liver disease:
Common Pitfalls to Avoid
- Do NOT use CIWA-Ar alone for diagnosis of AWS, as high scores can occur in sepsis, hepatic encephalopathy, anxiety disorders, and severe pain 1
- Do NOT give glucose-containing IV fluids before thiamine administration 1, 3
- Do NOT use long-acting benzodiazepines (diazepam, chlordiazepoxide) in patients with liver failure—switch to lorazepam 1
- Do NOT continue benzodiazepines beyond 10-14 days due to risk of dependence 1, 3
- Do NOT use haloperidol as monotherapy—it is only adjunctive for symptoms not controlled by benzodiazepines 1
