A wound dressing made of small, expanding sponges that has been confined to military use is now approved for civilian adults and adolescents.
The XSTAT 30 dressing uses a syringe-like applicator that injects 92 compressed cellulose sponges with an absorbent coating into the wound cavity. The sponges swell, creating a barrier to stanch severe bleeding. Each applicator can absorb about a pint of blood, and up to 3 applicators may be used on each patient (http://1.usa.gov/1QjdK56).
