Abstract:
Alcohol withdrawal delirium (AWD) is often refractory to conventional medication. We report a prospective series of patients treated with α2-agonist dexmedetomidine added to conventional sedation. Eighteen patients with AWD were diagnosed by Confusion assessment method for ICU score. Treatment, complications, length of stay (LOS) in ICU and hospital were recorded. In addition, hospital and 1-year mortality were assessed. Dexmedetomidine was given for 23.9 (18.4) h [mean (SD)]. All the patients also received benzodiazepines but three patients were given haloperidole. No patient was intubated. The maximum infusion rate of dexmedetomidine was 1.5 (1.2) µg/kg/h. Time to resolution of AWD was 3.8 (1.3) days. The ICU LOS was 7.1 (2.7) days and in-hospital LOS 12.1 (4.5) days. No adverse events were observed although one patient died from acute pancreatitis. The use of dexmedetomidine in AWD seems safe but warrants further studies.

Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
