Use of etomidate in an intensive care unit.

A resumé of two studies and retrospective survey of 52 patients in an intensive care unit receiving infusions of etomidate has demonstrated that the technique can be used effectively and safely to provide sedation in patients requiring artificial ventilation and those breathing spontaneously. In both studies all measured respiratory and cardiovascular indices remained within normal limits. There was a low incidence of muscle movements in all groups and there was no nausea, vomiting, or allergic reactions. Additionally, the technique was readily accepted by the patients.
