Lyofoam T has a specially shaped "cross-cut" that permits close fitting around external tubes, cannulae or pins. Lyofoam is a semi-permeable polyurethane foam dressing designed with a hydrophobic outer surface that resists fluid penetration and a hydrophilic inner surface that absorbs exudate and does not adhere to the wound base. Used in the management of lightly to moderately exuding wounds with minimal or no necrotic tissue or fibrin slough.
