Management of CIWA-Ar Score of 12
A CIWA-Ar score of 12 indicates moderate alcohol withdrawal requiring immediate pharmacological treatment with benzodiazepines plus thiamine supplementation. 1
Immediate Pharmacological Management
Benzodiazepine Selection and Dosing
For patients without liver dysfunction:
- Initiate chlordiazepoxide 50-100 mg orally, followed by 25-100 mg every 4-6 hours as needed, with a maximum of 300 mg in the first 24 hours 2
- Long-acting benzodiazepines like chlordiazepoxide provide superior protection against seizures and delirium tremens compared to shorter-acting agents 2, 1
- Use a symptom-triggered regimen rather than fixed-dose scheduling to prevent medication accumulation 1
For patients with liver dysfunction or elderly patients:
- Switch to lorazepam 6-12 mg/day or oxazepam, which are safer due to shorter half-lives and no active metabolites 2, 1, 3
- These patients require closer monitoring due to risk of excessive sedation or precipitating hepatic encephalopathy 3
Essential Thiamine Supplementation
- Administer thiamine 100-300 mg/day orally immediately to all patients with alcohol withdrawal 2, 1
- Thiamine must be given BEFORE any glucose-containing IV fluids to prevent precipitating acute Wernicke encephalopathy 2
- Continue thiamine for 2-3 months following resolution of withdrawal symptoms 2, 1
Assessment and Monitoring
Vital Signs and Complications
- Monitor continuously for autonomic instability including tachycardia, hypertension, fever, and sweating 2
- Assess for dangerous complications: dehydration, electrolyte imbalance (especially magnesium), infection, gastrointestinal bleeding, pancreatitis, hepatic encephalopathy, and renal failure 2
CIWA-Ar Monitoring
- Reassess CIWA-Ar scores regularly to guide ongoing benzodiazepine dosing 1
- A score ≥15 indicates progression to severe withdrawal requiring more aggressive treatment 1
Supportive Care
- Provide fluid and electrolyte replacement with careful attention to magnesium levels, as magnesium is commonly depleted in chronic alcohol use 2, 1
- Ensure adequate hydration and nutritional support 2
Treatment Setting Decision
Inpatient admission is recommended for:
- Significant withdrawal symptoms (CIWA-Ar >8-10) 2
- History of withdrawal seizures or delirium tremens 2
- Co-occurring serious medical illness (liver disease, infection, pancreatitis) 2
- Failure of outpatient treatment 2
- High levels of recent drinking (>80 g/day for ≥10 years) 2
Outpatient treatment may be appropriate if:
- Patient has mild-moderate withdrawal without complications 1
- Reliable support system is available 1
- Daily physician visits can be arranged for 3-5 days 2
Duration and Tapering
- Begin tapering benzodiazepines after initial symptom control is achieved 2
- Do not continue benzodiazepines beyond 10-14 days due to abuse potential 2, 1
- Most patients show symptom improvement by 3-5 days, with resolution typically within one week 2
Post-Acute Management
- Psychiatric consultation is mandatory after stabilization for evaluation, ongoing treatment planning, and long-term abstinence strategies 2, 1
- Consider relapse prevention medications such as baclofen, topiramate, or acamprosate after the withdrawal period 2, 1
- Complete abstinence is critical for improved outcomes, especially in patients with liver disease 1
Critical Pitfalls to Avoid
- Never administer glucose-containing IV fluids before thiamine, as this can precipitate acute Wernicke encephalopathy 2
- Do not use anticonvulsants for alcohol withdrawal seizures, as these are rebound phenomena with lowered seizure threshold, not genuine seizures 2
- Avoid naltrexone in patients with alcoholic liver disease due to potential hepatotoxicity 2
- Do not use phenothiazines, barbiturates, or antihistamines as first-line treatment due to toxicity or lack of efficacy 4
