Atraumatic care: EMLA cream and application of heat to facilitate peripheral venous cannulation in children.

The purpose of this study was to investigate whether the application of heat placed to a child's potential intravenous (IV) site after the application of EMLA Cream™ decreases vasoconstriction, therefore promoting atraumatic care in the hospitalized pediatric patient. Venipuncture in children is a painful and frequently performed procedure. While use of EMLA Cream™ to reduce pain on insertion is a common practice with pediatric patients, no studies had measured venous size in relation to EMLA Cream™ and heat application.
