Anesthetic recovery after a single bolus followed by 2-h infusion of cyclopropyl-methoxycarbonyl metomidate (CPMM; n = 4 dogs) or etomidate (n = 4 dogs). (A) Anesthesia scores for individual dogs as a function of time after receiving a single bolus followed by a 2-h infusion of CPMM or etomidate. CPMM and etomidate group dogs are shown as red and black symbols, respectively. (B) Mean times (± SD) required for dogs to recover to the indicated anesthesia scores (from an anesthesia score of 3) after bolus administration followed by a 2-h infusion of CPMM or etomidate. * P < 0.05 and **** P < 0.0001.
