Acute Alcohol Intoxication

Acute Alcohol Intoxication – Treatment Options

Introduction
Acute alcohol intoxication occurs after the ingestion of large amounts of ethanol, leading to central nervous system depression and multi-system effects. Clinical severity ranges from mild disinhibition and ataxia to life-threatening respiratory depression, hypoglycemia, arrhythmias, aspiration, and coma. Management focuses on supportive care, prevention of complications, and monitoring for co-ingestants or trauma.

1. Immediate Stabilization

• Airway, Breathing, Circulation (ABC): Ensure airway protection; intubation may be required in comatose or vomiting patients to prevent aspiration.

• Oxygen therapy: Administered if hypoxemia present.

• IV fluids: Isotonic saline to correct dehydration and maintain hemodynamic stability.

2. Specific Medical Management

• Glucose administration: 50 mL of 50% dextrose IV if hypoglycemia is present or suspected.

• Thiamine: 100 mg IV or IM before glucose in chronic alcohol users to prevent Wernicke’s encephalopathy.

• Electrolyte correction: Monitor and treat hypokalemia, hypomagnesemia, and hypophosphatemia.

• Naloxone trial: May be administered if opioid co-ingestion is suspected (no direct role in pure ethanol intoxication).

3. Symptomatic and Supportive Care

• Observation: Continuous monitoring of vital signs, oxygen saturation, and mental status.

• Positioning: Place unconscious patients in lateral recovery position to reduce aspiration risk.

• Temperature regulation: Treat hypothermia with warming measures.

• Antiemetics: Ondansetron or metoclopramide for persistent vomiting.

4. Advanced and Rescue Therapies

• Hemodialysis: Rarely required, but may be indicated in severe ethanol poisoning with extremely high serum ethanol levels and multi-organ compromise, or in cases of co-ingestion with methanol or ethylene glycol.

• Intensive care support: For patients with severe respiratory depression, arrhythmias, or refractory hypotension.

5. Complication Management

• Aspiration pneumonia: Early antibiotic therapy if aspiration occurs.

• Trauma assessment: Alcohol intoxication often masks head injuries or internal bleeding; imaging and surgical evaluation as necessary.

• Alcohol withdrawal: Anticipate in chronic users; benzodiazepines (e.g., diazepam, lorazepam) may be required if withdrawal develops.

6. Lifestyle and Preventive Measures

• Counseling on alcohol use and referral for addiction treatment programs.

• Avoidance of hazardous activities (driving, operating machinery) during and after drinking.

• Nutritional support and supplementation in chronic alcohol dependence.

7. Multidisciplinary Care

• Emergency physicians and intensivists: For acute stabilization.

• Toxicologists: For severe poisoning or mixed substance ingestion.

• Psychiatrists and addiction specialists: For long-term alcohol use disorder management.

• Social workers: For rehabilitation support and safe discharge planning.
