Inadvertent cast-saw burns are attributable to inadequately padded casts, improper technique, or uncooperative patients. Cast-saw blade temperatures recorded while splitting plaster and fiberglass casts are elevated to a degree that would increase the risk of a second- or third-degree burn. Using standardized plaster and fiberglass cast models, this study attempted to determine whether the elevated temperature was a product of the saw, blade design, blade material, technique of cast removal, or casting materials. The results demonstrated that cast-saw blades manufactured with stainless steel are poorly suited for a device that uses friction to separate a cast. Modifications to the technique and varying the cast-saw models did not reduce the blade temperature consistently to <120-130 degrees F during normal operations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
