Abstract
DYCLONINE hydrochloride (Dyclone; Astra Pharmaceuticals, Westboro, MA) is a topical anesthetic that was first introduced in 1952. It very effectively produces topical airway anesthesia for laryngoscopy and awake endotracheal intubation. This 40-yr-old drug is not consistently included in many of the anesthesia community's published lists of local anesthetics. Brief references may be found in some anesthesia texts. In other recently published anesthesia texts, we could not find any reference to dyclonine. 4-6 A unique local anesthetic agent, this ketone is structurally distinct from the two major classes of local anesthetic agents (aminoesters and aminoamides). 1,7,8 We report the use of dyclonine for topical anesthesia of the airway to facilitate awake intubation in a patient with a stated allergy to bupivacaine and procaine.
