Celox
Product Description CELOX is a new high-performance hemostatic material. It is a proprietary marine biopolymer designed to control high-volume arterial bleeding without cautery. CELOX is suitable for many applications ranging from deep arterial bleeds to superficial wounds. A clot forms within minutes after pouring the product into the wound. Excess granules form a gelled mass to protect the clot. The gelled material is easy to remove. CELOX does not generate any heat, produce burning, nor does it embed itself into the wound. CELOX works whether blood temperature is 98.7 or 65.4 and it works on heparinized blood. CELOX works independently of the blood clotting factors. The granules are lightweight, packaged in sterilized, sealed packets which are easy and fast to open. CELOX is poured into the wound and held down with gauze for 5 minutes. A compression bandage is then wrapped over the gauze covered wound and patient is transported. Reader Reviews Shell-based blood clotter works without heat By Kelly Kennedy - Staff writer Posted : Saturday Feb 10, 2007 13:21:15 EST A scientist walking down a beach in Washington state noticed lots of crabs with no legs -- but none of them showed any signs of bleeding. Most animals that lose a limb tend to bleed again after the initial injury, so the scientist wondered why the crabs had such clean wounds. The answer: Most animals don't have shells. "It was the chitosan in the shells," explained Limor Shemer, spokesperson for Celox. "It stopped the bleeding." The crustaceans' natural body armor now serves a similar purpose for soldiers and Marines in Iraq and Afghanistan through a new quick-clot agent, Shemer said. "The feedback's been very positive," she said. "It doesn't heat up." Unlike other quick-clot products troops have been using in the battle zone, the seashell product -- called Celox -- doesn't depend on the blood's natural clotting agent to work. Instead, the seashells bind with the person's blood to create a clot. That's important, because other blood-clotting agents, such as QuikClot, can heat up to temperatures of 230 degrees Fahrenheit -- enough to cause a second-degree burn. However, Z-Medica, the manufacturer of QuickClot, released a new product in September, QuikClot ACS+ -- a clotting sponge that does not heat up enough to burn the injured person. Celox also can be used on heparinized blood, or blood that has been treated so that it won't clot on its own. While HemCon -- which is standard issue for troops in combat zones -- also uses chitosan, studies have shown it doesn't work as well to prevent bleeding because it is a dressing. Celox, which comes in granules, is poured directly onto a wound, and therefore works well on deep or arterial wounds, Shemer said. Scientists at the Portsmouth Naval Center, N.H., applied Celox granules, HemCon bandages or QuikClot granules to pigs with severed blood vessels in their thighs after letting the animals bleed for three minutes. The study found that Celox reduced bleeding to nothing, HemCon to 33 percent and QuikClot to 8 percent, as opposed to a standard dressing, which brought bleeding down by 50 percent. "Although all three agents were superior to standard dressing with regard to re-bleed, only Celox improved survival in a lethal hemorrhagic groin injury compared to standard dressing," wrote Lt. Cmdr. Buddy Kozen in a letter about the study. Celox was approved by the FDA in June, and has been used in the war zones by Special Forces medics since September, Shemer said. Studies also found that even if Celox gets wet or is kept in humid conditions, it may get clumpy, but it still works. It can also be easily rinsed from the wound, Shemer said.
