Outpatient sedation for oral surgery. A new technique using etomidate

In an attempt to exploit the benefits and to reduce the incidence of side-effects of etomidate during intravenous sedation for nervous patients undergoing oral surgery under local analgesia, a series of four clinical trials were undertaken: a pilot study in which etomidate was preceded by a combination of pentazocine and diazepam; a double-blind study in which saline was randomly substituted for the etomidate, and two further studies in which the administration of etomidate was preceded by that of either pentazocine or diazepam alone. The combination of a small dose of diazepam (0.1 mg/kg) with an initial dose of etomidate (0.1 mg/kg) followed by increments of the latter as necessary proved to be most successful in reducing the severity of unwanted reactions while retaining the unique advantages of etomidate.
