A three-dimensional slow release agent absorbent dressing particularly suitable for use in sinus cavity or infective wounds comprises a wound-contacting layer surrounding outside of the dressing. The wound-contacting layer is a soft-film covered with tapered apertures and the bottom surface of said tapered apertures faces outside to contact a wound for discharging exudate from the wound in many directions and transmitting exudate via a diffusion guiding layer to absorbent articles. Said absorbent articles formed of high-molecular polymeric fibers are mixed with a certain concentration of water-soluble agents, such as antiseptic agents, enzymes and growth factor agents, in a suitable amount. After exudate is into absorbent articles, said polymeric fibers expand forming into the shape of gel to avoid exudate flowing backward to the wound, which is more effective in preventing the wound from secondary infection.
