Abstract
Abstract There is disclosed an improved surgical dressing which is adjustable for size and shape and which may be used as a disposable trauma, transportation, disaster or burn dressing. The surgical dressing comprises a unit of multiple layers of fluid absorbing material and a flexible, non-adhering, fluid permeable inner lining superposed congruently with the absorbent unit arranged such that the inner lining overlaps the edges of the absorbent unit. The edges of the inner lining are fastened to the absorbent unit and the multiple layers of the absorbent unit are fastened together along the plurality of preselected lines to permit selective adjustment of the size and shape of the dressing by cutting.
