Alcoholism
Considerations
-
Multisystem disease:
-
CNS: peripheral neuropathy, Wernicke-Korsakoff syndrome (ocular, ataxia, confusion), cerebral atrophy/dementia
-
Cardiovascular: cardiomyopathy, palpitations, arrhythmias
-
GI: liver dysfunction/cirrhosis, esophagitis, gastritis, pancreatitis, malnutrition
-
Heme: pancytopenia
-
Endocrine/metabolic: hypoglycemia, hypoalbuminemia, electrolyte abnormalities (hypokalemia, hypomagnesemia)
-
MSK: myopathies, osteoporosis
-
Other addictions
-
-
Altered pharmacology:
-
Induction of liver enzymes
-
↑ MAC
-
-
Alcohol withdrawal syndromes & need for CIWA protocol (tremors, autonomic hyperactivity, DTs)
Alcohol Withdrawal & Syndromes
-
Earliest & most common:
-
Generalized tremors that may be accompanied by perceptual disturbances (nightmares, hallucinations), autonomic nervous system hyperactivity (tachycardia, hypertension, cardiac dysrhythmias), nausea, vomiting, insomnia, & mild confusional states with agitation
-
Symptoms usually begin within 6 to 8 hours after a substantial ↓ in blood alcohol concentration & are typically most pronounced at 24 to 36 hours
-
These withdrawal symptoms can be suppressed by the resumption of alcohol ingestion or by administration of benzodiazepines
-
-
Delirium tremens:
-
Occurs in ~5% of those experiencing withdrawal
-
Symptoms begin 2-4 days after alcohol cessation
-
Manifests as hallucinations, combativeness, hyperthermia, tachycardia, hypertension or hypotension, & grand mal seizures
-
Treatment:
-
First line = benzodiazepines (titrated to effect without loss of respiration)
-
Beta blockers to reduce tachycardia & hypertension
-
Fix metabolic abnormalities (potassium, magnesium, & thiamine)
-
Severe cases will need ICU admission & propofol infusion/dexmedetomidine & possible intubation
-
Mortality = 10% (usually due to hypotension, dysrhythmias, or seizures)
-
-
-
Wernicke-Korsakoff syndrome:
-
Wernicke's encephalopathy:
-
Loss of neurons in the cerebellum
-
Acute syndrome requiring emergent treatment to prevent death & neurologic morbidity
-
-
Korsakoff's psychosis:
-
Chronic neurologic condition
-
Loss of memory resulting from the lack of thiamine (vitamin B1), which is required for the intermediary metabolism of carbohydrates
