The article focuses on the evaluation of the changes occurred on the polyurethane and silicone feeding tubes when they were exposed in fish oil. It states that the polyurethane and silicone enteral feeding tubes were cut into sections from 1-1.5 inches and was stored for 72 hours at room temperature. It mentions that light microscope was used in evaluating the tube sections and it was observed that the polystyrene foam was degraded by fish oil in just few minutes.
