What is SURGIFOAM made of?
SURGIFOAM Powder is made from the same safe, absorbable porcine gelatin that is used in SURGIFOAM* Gelatin Sponge, which has been used safely and effectively more than 100 million times.
What is surgical Gelfoam?
GELFOAM is a medical device intended for application to bleeding surfaces as a hemostatic. It is a water-insoluble, off-white, nonelastic, porous, pliable product prepared from purified pork Skin Gelatin USP Granules and Water for Injection, USP.
Does Gelfoam stop bleeding?
The first application of GELFOAM will usually control bleeding, but if not, additional applications may be made. For additional applications, fresh pieces should be used and prepared as previously described. Use only the minimum amount of GELFOAM, cut to appropriate size, necessary to produce hemostasis.
How long do you keep Gelfoam on?
When placed in soft tissue, GELFOAM is usually absorbed completely in four (4) to six (6) weeks, without inducing excessive scar tissue. When applied to bleeding nasal, rectal or vaginal mucosa, it liquefies within two (2) to five (5) days.
Can surgicel be left in wound?
Surgicel has a pH of 3. If the material is maintained in the wound for up to 120 days, a pH this low could slow healing. It is primarily a physical hemostatic agent, which acts as a barrier to blood and then becomes a sticky mass that serves as an artificial coagulum.
How do you remove Gelfoam from a wound?
If that happens, gently run warm water over the dressing until the dried blood softens and you can peel the outer bandage away. Be careful not to pull the absorbable dressing off the wound. If the warm water method alone doesn't work to loosen the bandage, you may pour hydrogen peroxide over the dressing.
Can you use Gelfoam in the mouth?
Hemostasis: In oral and dental surgery, GELFOAM Dental Sponges are an aid in providing hemostasis. GELFOAM may be used either dry or moistened, depending upon conditions present at operation and preference of the surgeon.
How long does it take Surgifoam to dissolve?
When used in appropriate amounts, SURGIFOAM® is absorbed completely within 4 to 6 weeks. When applied to bleeding mucosal regions, it liquefies within 2 to 5 days.
Does gel foam need to be removed?
Only the minimum amount of GELFOAM necessary to achieve hemostasis should be used. Once hemostasis is attained, excess GELFOAM should be carefully removed. The use of GELFOAM is not recommended in the presence of infection.
Is Gelfoam permanent?
Gelfoam can be a permanent occluding agent which does not require subselective catheter position for effectiveness and safety.
How long should Surgicel stay on?
The dissolution of Surgicel depends on the quantity, site of implantation and the environmental factors, and the process may last for between two and six weeks (8).
Why are Hemostatics used?
Hemostatics are drugs that are administered intravenously during emergencies to reduce hemorrhage (bleeding from a ruptured blood vessel) and prevent death from hemorrhage within a hospital setting or any prehospital situations.

How good is a tisseel?
In a group of 38 children with congenital heart defects, Tisseel gave excellent hemostasis in 31 patients, good hemostasis in 6 and poor in only 1 patient [21]. In a nationwide study of 140 patients requiring arterioarterial bypasses or arteriovenous shunts, the Tisseel group had 62.9% hemostasis compared to manual compression, which had only 31.4% efficacy. There were no adverse effects noted from use of the Tisseel [22].
What are the benefits of hemostasis?
When surgeons achieve rapid hemostasis, potential benefits include shorter duration operations, decreased requirement for transfusions, better management of an anticoagulated patient, overall improvement in patient recovery time and reduced wound exposure. The use of hemostatic agents, sealants and adhesives increases hemostasis and provides a range of benefits in vascular surgery. The importance of hemostasis has prompted the continued development of new agents including oxidized regenerated cellulose (ORC), porcine gelatin, bovine collagen, polysaccharide spheres and thrombin [5]. A wide range of surgical hemostatic agents for use in vascular surgery have been developed recently [5,6]. These agents vary widely in their mechanism of action, composition, ease of application, adherence to wet or dry tissue, immunogenicity and cost. These agents can be divided into three broad categories: hemostats, sealants and adhesives; these broad categories can be further subdivided [5]. Typically, hemostats may be divided into categories encompassing mechanical, active and flowables. Sealants can be further subdivided as fibrin sealants and synthetic sealants. Adhesives for vascular surgery are classified as cyanoacrylate or as albumin and glutaraldehyde (Table 1).
How does hemostasis occur in surgical procedures?
Over 51 million hospital-based surgical procedures are performed annually [1]. The effective management of bleeding to achieve hemostasis during surgical procedures is essential for promoting positive outcomes. The natural process of human hemostasis comprises a highly controlled process that sustains blood flow, while a thrombotic response to tissue injury takes place, encompassing a complex interplay between coagulation and fibrinolytic factors, platelets and the vessel wall. The dual stages of hemostasis include the primary cellular stage that is initiated directly following endothelial injury, which is characterized by vasoconstriction, the adhesion of inflammatory effector platelet cells and the creation of an initial malleable aggregated plug, consisting of platelets and fibrinogen. The secondary humoral stage, during which this soft plug is stabilized by the formation of a clot, is facilitated by platelets that sustain vasoconstriction and a reduction in blood flow through the secretion of thromboxane and serotonin. The coagulation cascade converts plasma-soluble fibrinogen to insoluble fibrin via thrombin, concurrently with the conversion of factor XIII to factor XIIIa, which initiates the cross-linking of fibrin monomers that result in the development of a stable clot [2–4]. An ideal set of hemostat characteristics would combine biodegradability with minimal side effects, as well as providing the rapid action in the achievement of hemostasis, while preventing thrombosis.
What are the three types of hemostasis agents?
These agents can be divided into three broad categories: hemostats, sealants and adhesives. They vary widely related to their mechanism of action, composition, ease of application, adherence to wet or dry tissue, immunogenicity and cost.
How does collagen hemostat work?
They bind tightly to blood surfaces to provide a matrix for clot formation and strengthening, as well as enhancement of platelet aggregation, degranulation and release of clotting factors, thus further promoting clot formation. They have been found to be effective in controlling arterial bleeding and in patients with low platelet counts. They are available in sheets and flours, conform and adhere to irregular surfaces and are ready to use out of the box. Although more expensive than porcine gelatin, hemostasis can generally be achieved in a shorter amount of time (1 – 5 min). It can be easily removed with irrigation and suction, reducing rebleeding and the need for multiple applications. Left in place, it is absorbed in 8 – 10 weeks. Problems that have been associated with bovine collage include swelling and allergic reaction. Therefore, collagen hemostats should not be used in any area where they may exert pressure on adjacent structures or for skin closure as it may interfere with healing of the skin edges, as well as not in patients with known allergies or sensitivities to materials of bovine origin. Popular collagen hemostats are Avitene, Helistat-Instat and Ultrafoam.
When did fibrin sealants become available?
Fibrin sealants have been available in Japan and Western Europe since the 1980s , but did not receive the FDA approval for use in the United States until 1998. Several studies have reported that fibrin sealants improve surgical outcomes due to shortened operating time, lower infection rates and other complications, as well as a reduction in blood loss [6,13–15]. Fibrin sealants are a good choice in vascular surgery, providing an effective means of sealing anastomoses prior to blood vessel pressurization and vascular clamp removal. They have been used primarily for adjunctive hemostasis in a variety of settings, including cardiovascular and aortic procedures and carotid endarterectomy. [16].
How does ORC work?
ORC products are stored at room temperature, can be used immediately, and absorb 7 – 10 times its own weight. They act in the intrinsic pathway causing contact activation and platelet activation and, as absorbed, a gelatinous mass is formed, aiding in clot formation. These products are used to control capillary, venous and small arterial bleeding, and can be cut into strips or smaller pieces for placement. They need to be applied dry and are absorbed within 4 – 8 weeks. ORC products should not be used in closed spaces due to potential swelling or for control of bleeding from large arteries. Three commercial forms are Surgicel, Oxycel and Surgicel Nu-Knit. Surgicel and Surgicel Nu-Knit come in knit, solid fiber form, whereas Oxycel comes in knit, hollow fiber form; however, they work essentially the same way.
