Abstract
Foam-based devices are aimed at redistributing pressure from body structures, in order to prevent pressure injury. Specialized devices based on foams, overlays, mattresses or integrated systems have the purpose of redistributing pressure. They are manufactured to control pressure, shear or frictional forces, maintenance of the microclimate or other therapeutic functions. The objective is to evaluate the interface pressure exerted on bony prominences with the use of viscoelastic polymer support surfaces. The analysis was clinical regarding a quasi-experimental study in which repeated measures of twenty healthy volunteers were evaluated in a standard operating table with viscoelastic polymer overlap and compared with the non-use of this support surface. The participants were placed in dorsal decubitus at a surgical table to evaluate the interface pressure in the bony prominences of the occipital, subscapular, sacral and calcaneal regions. Two evaluations were performed for each bone prominence with the use of sensors. Descriptive analyses and variance test was performed. The mean interface pressure was higher in the viscoelastic polymer than in the non-use of these support surfaces in the occipital (p <0.001), subscapular (p = 0.022), sacral (p <0.001), right calcaneus (p = 0.057) and left calcaneal (p = 0.041). The sacral and calcaneal regions presented higher mean values of interface pressure with the use of the viscoelastic polymer (42.90 mmHg and 36.55 mmHg, respectively). The viscoelastic polymer did not reduce the interface pressure when compared to the non-use of these support surfaces.
