  7. Preparations: Aluminum Chloride (e.g. Drysol, Xerac)
    1. Indications
      1. Hemostasis of minor bleeding typically following skin procedures (e.g. Shave Biopsy)
    2. Mechanism
      1. Hydrolyzes to form hydrogen chloride which has hemostatic and Vasoconstrictive properties
    3. Adverse Effects
      1. Local Paresthesias at application site
  8. Preparations: Ferric Subsulfate (e.g. Monsel's Solution, AstrinGen)
    1. Indications
      1. Control of bleeding from small wounds on skin or mucosa (e.g. Colposcopy biopsy)
    2. Background
      1. One of the oldest Hemostatic Agents (described by Monsel in the 1850s)
    3. Mechanism
      1. Denatures and coagulates Proteins to form a membrane over small blood vessels
    4. Technique
      1. Clean bleeding site and apply local pressure
      2. Insert cotton swab into Monsel's Solution and stir to mix
      3. Apply cotton swab to bleeding site
    5. Adverse Effects
      1. May cause discoloration of tissue to which it has been applied
  9. Preparations: Silver Nitrate
    1. Indications
      1. Hemostatic agent for small wounds
    2. Mechanism
      1. Silver Nitrate sticks applied to small bleeding sites release silver that binds tissue Proteins
      2. Bound Protein precipitates into a black eschar that obstructs small blood vessels
    3. Technique
      1. Clean bleeding site and apply local pressure
      2. Apply Silver Nitrate stick to bleeding site
    4. Adverse Effects
      1. Exercise care to avoid Tattooing (e.g. on face) and to avoid local spread and damage to adjacent tissue
  10. Preparations: Gelatin (Gelfoam, Surgifoam)
    1. Indications
      1. Small vessel bleeding typically from bone
    2. Mechanism
      1. Gelatin based network traps Platelets and Clotting Factors, facilitating clotting
      2. Gelatin is absorbant, swelling and compressing small bleeding sites
    3. Technique
      1. Various forms may be applied to bleeding sites including plugging bleeding open wounds
    4. Adverse Effects
      1. Risk of local infection at application site
  11. Preparations: Regenerated Oxidized Cellulose (Surgicel)
    1. Indications
      1. Small vessel bleeding typically following surgical procedure
    2. Technique
      1. Absorbable Fabric cut to size and applied to bleeding site
      2. May not be used with Thrombin
  12. Preparations: Topical Thrombin
    1. Indications
      1. Control of minor bleeding (e.g. Tongue Laceration) in patients with prolonged INR (e.g. Warfarin)
      2. Used in combination with gelatins
    2. Mechanism
      1. Thrombin facilitates Fibrinogen conversion to Fibrin in the formation of clot
    3. Preparations
      1. Bovine-derived Thrombin (Thrombin-JMI)
        1. Contraindicated in cow allergies
      2. Human plasma-derived Thrombin (Evithrom)
      3. Recombinant human Thrombin (rhThrombin)
  13. Preparations: Chitosan Dressing (HemeCon, Celox Gauze, ChitoGauze)
    1. Derived from Chitin is shellfish exoskeletons
    2. Mechanism
      1. Local Vasoconstriction
      2. Mobilizes Clotting Factors and Platelets
      3. Mechanical sealing
    3. 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)
  14. Preparations: Zeolite Mineral Dressing (QuickClot)
    1. Mechanism
      1. Factor Concentrator
      2. Increases Clotting Factor and Platelet concentration at wound sites via water absorption
    2. Efficacy
      1. Stops bleeding in 92% of wounds not stopped with direct pressure
      2. Effective for low pressure, venous bleeding
    3. Adverse effects
      1. Prior formulation caused severe local burns (no longer an issue with newer bead formulations)
  15. Preparations: Mineral Dressing with Impregnated Kaolin
    1. Mechanism (similar to Zeolite Mineral Dressings)
      1. Factor Concentrator
      2. Increases Clotting Factor and Platelet concentration at wound sites via water absorption
    2. Efficacy
      1. Slower control of bleeding
      2. Significantly increased survival in animal models
    3. Advantages
      1. Available as gauze rolls (3 inch wide, 4 yard long) that are now primary hemostatic agent used on battlefield

Hemostatic Agents (C0019120)

Definition (NCI) An agent that promotes hemostasis.
Definition (MSH) Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure.
Definition (CSP) agent that arrests the flow of blood.
