What is the X-stat device best described as?

• A. Compressed foam sponges in a syringe applicator that expand on contact with blood
• B. A manual suction device
• C. A wound closure device
• D. An absorbent gauze pad

Answer: (A)

The XSTAT is a mechanical tamponade device. It uses compressed foam sponges encased in a syringe-like applicator that rapidly expand when they contact blood. As the sponges swell inside the wound, they fill the cavity and press on bleeding vessels, quickly stopping the hemorrhage. This makes it especially useful for deep or noncompressible wounds where external pressure or tourniquets aren’t effective. It isn’t a suction device, a wound-closure device, or just an absorbent pad—the expanding foam inside the wound is what creates the hemorrhage control. The sponges stay in place to provide temporary control until surgical care can remove them and repair the injury.
