title: Benzyl alcohol with epinephrine as an alternative to lidocaine with epinephrine.
abstract: A randomized, prospective, double-blind study comparing benzyl alcohol with epinephrine, 1:100,000 (BA), and lidocaine with epinephrine, 1:100,000 (LID), as local anesthetics was carried out on adult patients with simple lacerations. The two study groups were compared for pain of infiltration (100 mm visual analog scale) and need for additional anesthesia. Pain scores were compared by a Mann Whitney Independent Rank Sum test and need for additional anesthesia by a Fishers Exact test. A total of 52 subjects (26 per group) were analyzed. The groups were similar in demographics and wound characteristics. The median pain score for BA, 7.5 mm, was less than for LID, 19.5 mm (p = 0.049). Although more patients receiving BA required additional anesthesia as compared to LID (8/26 versus 2/26), this difference did not reach statistical significance. BA is a reasonable alternative local anesthetic to LID for patients who are allergic to LID.
