Hemostatic agents: Difference between revisions

Revision as of 07:40, 12 January 2016

Active Agents

Plant-Based	Oxidized cellulose (OC) and oxidized regenerated cellulose (ORC)
Gelatin-based	Purified pork or bovine skin; absorbs 45 times its weight of its initial volume causing hemostasis. Excessive swelling can lead to nerve compression
Collagen-based	Derived from tissue; shows cell compatibility, adhesion, growth and migration.
Fibrin-based	High concentrations of fibrinogen, thrombin and additional components (clotting factors)
Thrombin-based	Directly participate in the coagulation cascade process that promotes and modulates coagulation. Provides a lattice for platelet aggregation and thrombus formation.
Chitin-based	Polysaccharide biopolymer produced naturally by algae through fermentation. Also known as chitosan in its deacetylated form. Chitosan has been shown to be more effective that chitin in controlling severe hemorrhage.

Types

Use

For compressible hemorrhage not amenable to tourniquet use or as an adjunct to tourniquet removal (if evacuation time is anticipated to be longer than two hours), use Combat Gauze
Celox Gauze and ChitoGauze may also be used if Combat Gauze is not available.
Hemostatic dressings should be applied with at least 3 minutes of direct pressure.

 ==Use==
-#Assess for unrecognized hemorrhage and control all sources of bleeding. If not already done, use a CoTCCC-recommended tourniquet to control life-threatening external hemorrhage that is anatomically amenable to tourniquet application or for any traumatic amputation. Apply directly to the skin 2-3 inches above wound.

Before releasing any tourniquet on a casualty who has been resuscitated for hemorrhagic shock, ensure a positive response to resuscitation efforts (i.e., a peripheral pulse normal in character and normal mentation if there is no [[traumatic brain injury]] (TBI). If the bleeding site is appropriate for use of a junctional tourniquet, immediately apply a CoTCCC-recommended junctional tourniquet. Do not delay in the application of the junctional tourniquet once it is ready for use. Apply hemostatic dressings with direct pressure if a junctional tourniquet is not available or while the junctional tourniquet is being readied for use.

-#Reassess prior tourniquet application. Expose wound and determine if tourniquet is needed. If so, replace tourniquet over uniform with another applied directly to skin 2-3 inches above wound. If a tourniquet is not needed, use other techniques to control bleeding.

-#When time and the tactical situation permit, a distal pulse check should be accomplished. If a distal pulse is still present, consider additional tightening of the tourniquet or the use of a second tourniquet, side by side and proximal to the first, to eliminate the distal pulse.
-#Expose and clearly mark all tourniquet sites with the time of tourniquet application. Use an indelible marker.
