Abstract:
This study describes deep sedations performed for painful procedures completed in the emergency department at an academic tertiary care hospital during an 18-month period. One hundred consecutive cases were retrospectively reviewed to describe indications, complications, procedural lengths, medication dosing, and safety of these sedations. Propofol and etomidate were the preferred agents. We found that there were relatively few complications (10%), with only 2 of these (2%) being major complications. All complications were brief and did not adversely affect patient outcomes. This data further demonstrate the safety profile of deep sedation medications in the hands of emergency physicians trained in sedation and advanced airway techniques.

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...

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...
