Contents
Background
- Rate of ETOH elimination is 15-30mg/dL/hr (depending on degree of chronic alcohol intake)
Clinical Features
- Classic Features
- Slurred speech
- Nystagmus
- Ataxia
- N/V
- Alcohol odor on breath
- Respiratory depression
- Coma
- Other Features (if malnourished)
- Hypoglycemia
- Ketoacidosis
- Lactic acidosis
- Epigastric pain (pancreatitis)
Mellanby effect
- Impairment is greater at a given blood alcohol concentration when the level is rising than when it is falling. [1]
Differential Diagnosis
Sedative/hypnotic toxicity
- Absinthe
- Barbiturates
- Benzodiazepines
- Chloral hydrate
- Gamma hydroxybutyrate (GHB)
- Opioids
- Toxic alcohols
Diagnosis
Clinical diagnosis. No specific workup required, but the following may be considered based on clinical picture/gestalt:
- Fingerstick glucose
- Blood alcohol level (BAL)
- Correlates poorly with degree of intoxication[2]
Management
- GI decontamination
- Activated charcoal ineffective (ETOH is too rapidly absorbed)
- Hypoglycemia
- Give glucose immediately (do not have to wait to give thiamine first)
- "Banana Bag"
- IV form is not justified
- Likelihood of vitamin deficiency (except for thiamine) is low
- IVF does not hasten ETOH elimination
Disposition
- Can be discharged once patient at baseline mental status, able to tolerate PO and ambulate without assistance.
