Randomized Controlled Trial Comparative Study
A Non-Inferiority Randomized Controlled Trial Comparing the Clinical Effectiveness of Anesthesia Obtained by Application of a Novel Topical Anesthetic Putty With the Infiltration of Lidocaine for the Treatment of Lacerations in the Emergency Department.
We test the hypothesis that anesthesia, measured as pain scores, induced by a novel topical anesthetic putty is non-inferior (margin=1.3) to that provided by conventional lidocaine infiltration for the repair of lacerations. ⋯ The novel topical anesthetic putty was not inferior to infiltration with lidocaine with respect to the pain experienced during suturing, and this putty is a feasible alternative to infiltration anesthesia of lacerations in the ED.

Allergic reactions are common presentations to the emergency department (ED). An unknown proportion of patients will develop biphasic reactions, and patients are often monitored for prolonged periods to manage potential reactions. We seek to determine the incidence of clinically important biphasic reactions. ⋯ Among ED patients with allergic reactions or anaphylaxis, clinically important biphasic reactions and fatalities are rare. Our data suggest that prolonged routine monitoring of patients whose symptoms have resolved is likely unnecessary for patient safety.
