Abstract: A disposable superabsorbent article, and methods of use thereof, has superabsorbent cross-linked acrylate particles enveloped in a clean or sterile environment by an adhesively-sealed or heat-sealed plastic; paper; creped or microcreped paper or plastic; or woven, netted, nonwoven or fabric envelope, in shapes allowing for internal or external use, which permit the improved absorption and retention of fluids in medical, dental, veterinary, emergency care, mortuary, or surgical settings. Axial, circumferential, stellate, or other organized or random pleating or creping in either a single layer or in strata, and breakaway tabs in an alternative embodiment, are provided in the envelope to allow for controlled directional expansion of the fluid absorption. The superabsorbent article may be impregnated with therapeutically-effective amounts of antibiotic, antimicrobial, anticoagulating, or hemostatic or other agents.
