The U.S. Food and Drug Administration cleared the use of the XSTAT 30 wound dressing, an expandable, multi-sponge dressing used to control severe, life-threatening bleeding from wounds sustained from gun shots.

The radical new dressing can be applied to areas that a tourniquet cannot be placed (such as the groin or armpit) in battlefield and civilian trauma settings, the FDA said in a press statement.

The clearance expands the device's indication from use by the military only to use in adults and adolescents in the general population.

The device is available in packages of one or three syringe-style applicators containing 92 compressed, cellulose sponges that have an absorbent coating. The sponges expand and swell to fill the wound cavity, creating a temporary physical barrier to blood flow.

The number of sponges needed for effective hemorrhage control will vary, depending on the size and depth of the wound. Each applicator can absorb about a pint of blood, and up to three applicators may be used on a patient.

The use of the dressing can help early control of severe bleeding, prevent shock and may be life-saving. According to the United States Army Institute of Surgical Research, 30 to 40 percent of civilian deaths by traumatic injury are the result of hemorrhaging. Of those deaths, 33 to 56 percent occur before the patient reaches a hospital.

"When a product is developed for use in the battlefield, it is generally intended to work in a worst-case scenario where advanced care might not be immediately available," said William Maisel, M.D., M.P.H., acting director of the Office of Device Evaluation in the FDA's Center for Devices and Radiological Health. "It is exciting to see this technology transition to help civilian first responders control some severe, life-threatening bleeding while on the trauma scene."

XSTAT 30 is cleared for use in patients at high risk for immediate, life-threatening, and severe hemorrhagic shock and non-compressible junctional wounds, when definitive care at an emergency care facility cannot be achieved within minutes.

XSTAT 30 is not indicated for use in certain parts of the chest, abdomen, pelvis or tissue above the collarbone, the press statement said.

The dressing can be used for up to four hours, which could allow time for the patient to receive surgical care.

The number of sponges needed for effective hemorrhage control will vary, depending on the size and depth of the wound. Each applicator can absorb about a pint of blood, and up to three applicators may be used on a patient.

The FDA cleared XSTAT 30 through the 510(k) review process after the manufacturer demonstrated the product was substantially equivalent to the XSTAT, which was granted marketing authorization for battlefield use in April 2014. XSTAT 30 is manufactured by RevMedX, Inc., in Wilsonville, Ore, according to FDA.
