II. Background

  1. Derived from Chitin is shellfish exoskeletons

III. Mechanism

  1. Topical Hemostatic Agent
  2. Local Vasoconstriction
  3. Mobilizes Clotting Factors and Platelets
  4. Mechanical sealing

IV. Efficacy

  1. Stops bleeding in 97% of wounds not stopped with direct pressure
  2. However, bleeding restarts within 1 hour in up to 70% of cases (and nearly all arterial Hemorrhage)
