The present invention is directed to a hemostatic material comprising a compacted, hemostatic aggregates of cellulosic fibers. In some aspects, the hemostatic material further includes additives, such as carboxymethyl cellulose (CMC) or other polysaccharides, calcium salts, anti-infective agents, hemostasis promoting agents, gelatin, collagen, or combinations thereof. In another aspect, the present invention is directed to a method of making the hemostatic materials described above by compacting a cellulosic-based material into hemostatic aggregates. In another aspect, the present invention is directed to a method of treating a wound by applying hemostatic materials described above onto and/or into the wound of a patient.La presente invención se dirige a un material hemostático que comprende agregados hemostáticos compactados de fibras celulósicas; en algunos aspectos, el material hemostático incluye, además, aditivos, tales como carboximetilcelulosa (CMC) u otros polisacáridos, sales de calcio, agentes antiinfecciosos, agentes promotores de la hemostasia, gelatina, colágeno o combinaciones de estos; en otro aspecto, la presente invención se dirige a un método para fabricar los materiales hemostáticos descritos anteriormente al compactar un material basado en celulosa en agregados hemostáticos; en otro aspecto, la presente invención se dirige a un método para tratar una herida al aplicar los materiales hemostáticos descritos anteriormente sobre y/o en la herida de un paciente.
