Acute Alcohol Withdrawal

Acute alcohol withdrawal stems from chronic GABA receptor insensitivity, resulting in central nervous system hyperactivity upon cessation. Effective clinical management centers on benzodiazepines, preferably administered via symptom-triggered regimens like the CIWA scale to minimize over-sedation and shorten hospital stays. While benzodiazepines serve as the primary treatment, clinicians must prioritize thiamine replacement before glucose administration to prevent Wernicke-Korsakoff syndrome, characterized by encephalopathy and oculomotor dysfunction. Although mortality rates for delirium tremens have dropped significantly since the early 20th century, severe cases remain life-threatening, often complicated by arrhythmias, aspiration, or underlying comorbidities like pancreatitis. Management strategies may also include beta-blockers for autonomic control, though clinicians must remain vigilant for polysubstance withdrawal and the potential for benzodiazepine-resistant delirium, which occasionally necessitates intensive care unit intervention and alternative therapies.
