The study, authored by Anna Taddio, MD, of the University of Toronto and colleagues, reviewed data on 831 patients in 18 studies and found that warming injections produced a “clinically meaningful reduction in pain.” The reduction did not differ depending on the amount of anesthetic injected.
Injections were warmed using controlled water baths, incubators, fluid warmers, baby food warmers, warming trays or syringe warmers, according to the report. Warming local anesthetics reduced pain by 11 mm on a 100 mm scale on average.
