Thermal spread is an unavoidable side-effect of electrocautery, however limiting it is important for minimizing damage to surrounding tissues. LigaSure 5 mm Blunt Tip has been in use since 2009 while Voyant 5 mm Fusion has only been FDA approved since 2018. Our hospital, a rural academic tertiary care center, recently moved to purchasing Voyant because of cost concerns. We aimed to compare the thermal spread of the two tools on raw pork meat at two different cut depths and on both right and left sides. The LigaSure device had significantly less thermal spread than Voyant across all measurements. Based on our data, the LigaSure device should be chosen for use despite the increased cost.

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.
