Study Objective:
To review our experience with etomidate in nonintubated patients in the emergency department.
Design:
A 2-year retrospective chart review of consecutive patients receiving etomidate for sedation.
Setting:
Emergency department of a university-based teaching hospital.
Patients:
Forty-eight patients who underwent painful procedures in the emergency department.
Measurements And Main Results:
Demographics, dosing information, recovery times, and adverse events were abstracted using a standardized data collection form. Forty-eight nonintubated patients were sedated with etomidate. Mean age was 34 years (range 6-80 yrs); 38 were men and 10 women; two were children. The mean initial dose of etomidate was 13 mg. Adverse events occurred in 11 (21%) patients. None sustained any substantial morbidity as indicated by need for intubation, prolonged emergency department stay, or hospital admission.
Conclusion:
Although controversial, etomidate holds promise as a potent sedative agent for patients undergoing painful procedures in the emergency department. A large prospective evaluation is needed to document the performance and complications of this agent.

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...
