From the Research
Alcoholic ketoacidosis is a metabolic condition that requires immediate management with fluid resuscitation, glucose and vitamin supplementation, electrolyte repletion, and evaluation for other conditions, as outlined in the most recent study 1.
Definition and Pathophysiology
Alcoholic ketoacidosis (AKA) is defined by metabolic acidosis and ketosis in a patient with alcohol use, resulting from poor glycogen stores and elevated nicotinamide adenine dinucleotide and hydrogen, leading to metabolic acidosis with elevated beta-hydroxybutyrate levels 1. Patients with AKA most commonly present with a history of alcohol use, poor oral intake, gastrointestinal symptoms, and ketoacidosis on laboratory assessment.
Management
Management of AKA includes:
- Fluid resuscitation with IV normal saline infusion, typically 1-2 liters initially, followed by maintenance fluids
- Glucose administration (D5W or D5NS) to reverse the ketogenic state by stimulating insulin release
- Thiamine (100 mg IV) given before glucose to prevent precipitating Wernicke's encephalopathy
- Electrolyte replacement, particularly potassium, magnesium, and phosphate, as these are commonly depleted
- Bicarbonate therapy if pH is severely low (<7.1), though this is controversial
- Monitoring of vital signs, electrolytes, glucose, and acid-base status
- Addressing the underlying cause through alcohol cessation and nutritional support
Key Considerations
- Most patients respond rapidly to treatment, with resolution of ketoacidosis within 24 hours 2
- The recovery period may be complicated by alcohol withdrawal symptoms requiring appropriate management with benzodiazepines
- AKA may be a significant cause of mortality in patients with alcohol dependence, highlighting the importance of prompt and effective management 3
