Referral and warning signs
When to refer
Refer to Hospital (HC3/HC4/H) ALL patients experiencing moderate-severe alcohol withdrawal (significant autonomic hyperactivity, hallucinations, delirium), withdrawal seizures, or suspected Wernicke's encephalopathy. Patients with mild withdrawal may potentially be managed outpatient ONLY if reliable support, close follow-up possible, and no history of complicated withdrawal or significant comorbidities (generally inpatient management is safer). Refer patients with severe underlying organ damage (e.g., decompensated cirrhosis).
Red flags
- Delirium (disorientation, fluctuating consciousness)
- Persistent hallucinations
- Seizures
- Severe autonomic hyperactivity (HR >120, BP >160/100, Temp >38.5°C)
- Signs of Wernicke's encephalopathy (confusion, ataxia, ophthalmoplegia)
- Signs of severe liver disease (jaundice, ascites, encephalopathy)
- Significant electrolyte abnormalities
- Inability to take oral medication/fluids
Signs and symptoms
- Chronic Effects:
- - Malnutrition features: Weight loss, muscle wasting, dry scaly skin, brittle hair, vitamin deficiencies (esp. Thiamine - B1, Folate, B12).
- - Liver Disease (Alcoholic Liver Disease): Poor appetite, nausea, jaundice, abdominal distension (ascites from cirrhosis), spider angiomata, palmar erythema, hepatomegaly, elevated LFTs, coagulopathy.
- - Neurological Damage: Memory loss ( Korsakoff syndrome), peripheral neuropathy (numbness/tingling), cerebellar degeneration (ataxia, gait disturbance), tremors.
- - Cardiovascular: Cardiomyopathy, hypertension, arrhythmias.
- - Gastrointestinal: Gastritis, pancreatitis, esophageal varices.
- Alcohol Withdrawal Syndrome (AWS) - Spectrum of symptoms starting ~6-24 hours after last drink:
- - Mild Withdrawal (6-36h): Anxiety, agitation, irritability, insomnia, tremors ('shakes'), palpitations, sweating (diaphoresis), headache, nausea/vomiting.
- - Withdrawal Seizures (6-48h): Generalized tonic-clonic seizures. Usually brief, single or few.
- - Alcoholic Hallucinosis (12-48h): Visual, auditory, or tactile hallucinations, but typically with clear sensorium (patient knows they are hallucinating).
- - Delirium Tremens (DTs) (48-96h, peak ~72h): Severe manifestation. Characterized by: Delirium (confusion, disorientation), severe agitation, prominent visual hallucinations, marked autonomic hyperactivity (tachycardia, hypertension, hyperthermia, profuse sweating), tremor. Medical emergency with significant mortality.
- Wernicke's Encephalopathy (Acute Thiamine Deficiency): Triad of Acute Mental Confusion, Ataxia (gait/limb), and Ophthalmoplegia (nystagmus, gaze palsies). Can be precipitated by glucose administration without prior thiamine. Medical emergency requiring immediate thiamine.
Risk factors
- Heavy, prolonged alcohol consumption.
- Poor nutritional status (associated with chronic alcohol use).
- Abrupt cessation or significant reduction in alcohol intake in a dependent individual (triggers withdrawal).
- Concurrent illness or surgery can precipitate withdrawal or Wernicke's.
- Previous history of complicated withdrawal (seizures, DTs).
Diagnosis
Clinical assessment
History of chronic heavy alcohol use. Clinical features of chronic organ damage. Recognition of characteristic withdrawal symptoms (tremor, autonomic hyperactivity, hallucinations, delirium, seizures) temporally related to decreased alcohol intake. Clinical diagnosis of Wernicke's based on triad (often incomplete). Use assessment tools like CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, revised) to quantify withdrawal severity and guide treatment (requires trained staff).
Investigations
- Check Blood Glucose: Rule out hypoglycemia.
- Electrolytes: Check for disturbances (hypokalemia, hypomagnesemia, hypophosphatemia common).
- Liver Function Tests (LFTs), INR: Assess liver damage/function.
- Complete Blood Count (CBC): Check for anemia (macrocytic), thrombocytopenia.
- Thiamine levels (rarely available acutely).
- Consider: ECG (arrhythmias, QT prolongation), CT Head (if trauma, focal deficits, or Wernicke's suspected to rule out other causes), Lumbar Puncture (if meningitis suspected).
- Rule out other causes of symptoms (infection/sepsis, metabolic disorders, drug intoxication/withdrawal, head injury, hepatic encephalopathy).
Diagnostic criteria
Clinical syndrome consistent with alcohol withdrawal (tremor, autonomic hyperactivity, seizures, hallucinations, delirium) in patient with history of chronic alcohol use and recent decrease/cessation, after excluding other causes. Clinical diagnosis of Wernicke's (requires high suspicion). Clinical/lab evidence of chronic organ damage.
Management
Non-pharmacological management
- Supportive Care: Quiet environment, reassurance, frequent reorientation.
- Nutritional Support: Adequate hydration (IV fluids initially if needed), nutrition.
- Monitoring: Frequent vital signs (HR, BP, Temp, RR, SpO2). Use CIWA-Ar scoring if possible to guide sedation.
- Seizure Precautions: If history of withdrawal seizures or high risk.
Pharmacological treatment
- Alcohol Withdrawal Syndrome (AWS) Management:
- - Benzodiazepines (FIRST LINE): Substitute for alcohol's GABA-ergic effects, prevent seizures and DTs. Long-acting agents (Diazepam, Chlordiazepoxide) preferred for smoother withdrawal, easier titration. Short-acting (Lorazepam, Oxazepam) preferred in elderly or severe liver disease. Use symptom-triggered therapy (give dose based on withdrawal severity score, e.g., CIWA-Ar) or fixed-schedule taper. Example: Diazepam 5-10 mg IV/PO every 1-2 hours PRN based on symptoms, titrate to achieve light sedation (rousable). Higher doses often needed for severe withdrawal/DTs. Monitor respiratory status closely.
- - Phenobarbital: Second-line agent or adjunct for refractory withdrawal or if benzodiazepines contraindicated/ineffective. Requires careful monitoring due to respiratory depression risk. Dose 100-200mg slow IV (specialist use).
- - Antipsychotics (e.g., Haloperidol): Use cautiously and ONLY for severe agitation/hallucinations unresponsive to adequate benzodiazepine sedation. Can lower seizure threshold and prolong QTc. Dose: 2.5-5 mg IM/PO up to 3 times daily. Avoid as monotherapy.
- Thiamine Replacement (CRITICAL): Give Thiamine 100 mg IV or IM to ALL patients with suspected chronic alcohol use presenting with withdrawal, altered mental status, or needing glucose. Give BEFORE glucose. For suspected/confirmed Wernicke's: High dose Thiamine 100-500 mg IV/IM every 8 hours for 3-5 days, then daily oral.
- Electrolyte Replacement: Aggressively replete Magnesium, Potassium, Phosphate based on levels.
- Multivitamins & Folate: Supplement due to common deficiencies.
- Hypoglycemia Treatment: IV Dextrose (AFTER Thiamine).
- Fluid Management: IV fluids initially, monitor balance carefully (risk of fluid overload if cardiac/liver issues).
Monitoring
Frequent monitoring of vital signs (esp. HR, BP, Temp for autonomic hyperactivity). Monitor withdrawal severity (CIWA-Ar score). Monitor neurological status (level of consciousness, orientation, hallucinations, tremor, ataxia, nystagmus). Monitor fluid balance, electrolytes, glucose. Monitor for complications (seizures, aspiration, infection).
Complications
- Withdrawal Seizures, Status Epilepticus
- Delirium Tremens (DTs)
- Wernicke-Korsakoff Syndrome (permanent memory impairment)
- Aspiration Pneumonia
- Rhabdomyolysis
- Arrhythmias, Sudden Cardiac Death
- Gastrointestinal Bleeding (gastritis, varices)
- Infections/Sepsis
- Fluid/Electrolyte disturbances
- Progression of underlying organ damage (liver failure, cardiomyopathy)
- Trauma from falls/agitation
Prevention
- Early identification and treatment of alcohol use disorder.
- Nutritional support including thiamine supplementation for chronic heavy drinkers.
- Planned, medically supervised detoxification for dependent individuals wishing to stop.
- Patient education about risks of abrupt cessation.
- Referral to long-term treatment programs (counseling, support groups, medication-assisted treatment).
Patient education
- Explain the nature of alcohol withdrawal and its potential dangers.
- Discuss the role of medications (benzodiazepines, thiamine).
- Emphasize the importance of complete abstinence for recovery.
- Provide information and strong recommendation for referral to long-term alcohol treatment programs and support groups (e.g., AA).
- Educate on nutritional needs, including thiamine.
Uganda-specific notes
Chronic alcohol use disorder is prevalent. Thiamine deficiency and Wernicke's are likely under-recognized; maintain high suspicion and give thiamine empirically. Benzodiazepines are mainstay for withdrawal; Diazepam often used. Resources for intensive monitoring and management of severe DTs may be limited. Early recognition and treatment of withdrawal are key to prevent progression to DTs. Referral for long-term rehabilitation services may be challenging.
