Evarrest

What is Evarrest[edit | edit source]

Evarrest (fibrinogen human and human thrombin patch) is used with manual compression as an adjunct to hemostasis.

EVARREST® is a fibrin sealant patch indicated for use with manual compression as an adjunct to hemostasis in adult patients undergoing surgery, when control of bleeding by conventional surgical techniques (such as suture, ligature, and cautery) is ineffective or impractical.

Limitations for Use:

Cannot be used in place of sutures or other forms of mechanical ligation in the treatment of major arterial or venous bleeding.
Not for use in children under one month of age
Laparoscopic and other minimally invasive surgeries where manual compression would be difficult to achieve.

The mechanism of action of EVARREST is based on the interaction between the biological components and the physiology of the fibrin clot formation.
Upon contact with a bleeding wound surface, the biological components embedded in the patch component are hydrated, and the subsequent fibrinogen-thrombin reaction initiates the last step in the cascade of biochemical reactions - conversion of fibrinogen into fibrin monomers that further polymerize to form the fibrin clot.
Hemostasis is achieved when the formed fibrin clot integrates with the patch component and adheres to the wound surface thus also providing a physical barrier to bleeding.

This medicine cannot be used for:

Bleeding from large defects in visible arteries or veins.
Intravascular application
Individuals known to have anaphylactic or severe systemic reaction to human blood products

Recommended dosage:

Determine the number of patches to be applied based upon the surface area and anatomic location of the bleeding to be treated.
Do not use more than eight 2 × 4 inch (5.1 × 10.2 cm) patches.

Administration:

Keep the patch dry until use.
Place the powdery (active) side of the patch on the surface of tissue.
Apply immediate manual compression over the entire surface of the patch and maintain contact pressure for 3 minutes to control the bleeding.

The most common side effects of this medicine include:

Thrombosis can occur if absorbed systemically. Apply topically to the bleeding site only.
EVARREST Can cause hypersensitivity reactions including anaphylaxis.
Avoid application to contaminated areas of the body or in the presence of active infection. Infection can occur.
EVARREST® contains oxidized regenerated cellulose which adheres to bleeding surfaces. Inadvertent adhesions can occur.
Avoid use in, around, or in proximity to, foramina in bone or areas of bony confine where swelling may cause compression.
Use the least number of patches required to cover the entire bleeding area.
Because the biological components of this product are made from human plasma, it may carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

In case of overdose, call the poison control helpline of your country. In the United States, call 1-800-222-1222.

Overdose related information is also available online at poisonhelp.org/help.
In the event that the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services. In the United States, call 911.

There are no data with EVARREST® use in pregnant women to inform a drug-associated risk.
It is not known whether EVARREST can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity.
EVARREST should be applied to a pregnant woman only if clearly needed.
