[Dexmedetomidine in the treatment of acute alcohol withdrawal delirium].

Alcohol withdrawal syndrome has a high clinical prevalence. Severe cases must be treated in an intensive care unit and are associated with a high mortality rate, depending on patient comorbidities. Clinical requirements include sedation, control of vegetative symptoms, treatment of hallucinations and, when necessary, anticonvulsive therapy.

[Dexmedetomidine].

Dexmedetomidine is a highly selective α2-receptor agonist with sedative, analgetic and anxiolytic effects. It is chemically related to clonidine and has been an authorized drug in Europe since September 2011. Dexmedetomidine enables a level of sedation in which mechanically ventilated patients may be woken by verbal stimulation (Richmond agitation sedation scale RASS 0--3).
