Etomidate

From Dog

Etomidate is a short acting intravenous anaesthetic agent used for the induction of general anaesthesia and for sedation.

This drug can be used in anesthesia-induction protocols that involve the use of isoflurane for maintenance of anesthesia[1].

Caution should be exercised when using various benzodiazepine drugs such as midazolam as their combination causes marked increase in intraocular pressure and miosis[2].

It is an induction agents that cause minimal cardiovascular changes in surgical emergencies such as gastric dilatation-volvulus[3].

Recommended induction rate is 2 - 3 mg/kg given intravenously[4].
