Commercial fibrinogen preparations Purified, pasteurized fibrinogen concentrate offers an alternative to cryoprecipitate for fibrinogen supplementation therapy, and two recent studies directly compared the efficacy of these two therapies. Safety Few reports have described the rate of adverse events associated with cryoprecipitate, but results from a haemovigilance scheme in Quebec reported 6. Current licensing and regulatory status Currently, cryoprecipitate is licensed for use in certain indications in the UK, the USA, Canada, Australia, and New Zealand; however, it has been withdrawn from use in most of Western Europe because of safety concerns.

Should not be used if virus-inactivated factor concentrates are available Control of uraemic bleeding only after other modalities have failed Do not use unless results of laboratory studies indicate a specific haemostatic defect for which this product is indicated Indicated as second-line therapy for vWD and haemophilia A.

Coagulation factor preparations other than cryoprecipitate are preferred when blood component therapy is needed for management of vWD and haemophilia A. Cryoprecipitate may be given when a large volume of plasma is contraindicated Cryoprecipitate can be used to manage intracranial bleeding during or post-tPA administration in stroke patients, or other clinical scenarios Cryoprecipitate can be used to treat FXIII deficiency if specific coagulation factor concentrate is not available Cryoprecipitate can be used in vWD unresponsive to DDAVP and in those locations where Factor VIII: C concentrates are not available for haemophilia A patients.

Every effort must be made to obtain the preferred recombinant factor concentrate for haemophiliacs before the use of cryoprecipitate Worldwide World Federation of Hemophilia WFH Guidelines for the management of hemophilia 89 The WFH strongly recommends the use of viral-inactivated plasma-derived or recombinant concentrates in preference to cryoprecipitate for the treatment of haemophilia and other inherited bleeding disorders.

Point-of-care monitoring Most guidelines recommend that cryoprecipitate be administered in response to fibrinogen levels decreasing below a certain threshold; however, in an emergency setting, turnaround times for the Clauss fibrinogen assay are too long to effectively guide administration of haemostatic therapy in patients with acquired coagulopathic bleeding.

Cost Cost is highly influential in decision-making policies. Future directions Further developments may address one of the main concerns regarding the use of cryoprecipitate, namely the risk of pathogen transmission. Conclusion Despite the acceptance of cryoprecipitate for fibrinogen supplementation in acquired coagulopathy in many countries, there remains a lack of Level 1 evidence to support its use.

Transfusion of cryoprecipitate is used for patients who are in need of fibrinogen replacement and occasionally for inherited disorders. What is cryoprecipitate? It is rich in plasma proteins such factor 8, fibrinogen, factor 13, von Willebrand factor, and Fibronectin.

One of those components, factor 8, is also called antihemophilic factor or AHF, which is why cryo is sometimes called cryoprecipitated antihemophilic factor or cryoprecipitated AHF. Pictured here is a thawed cryoprecipitate pool ready for transfusion. They range in color from pale to dark yellow and can even appear as an even, thick, whitish liquid. Cryo is manufactured from Fresh frozen plasma FFP collected from whole blood donation.

Fresh Frozen Plasma is plasma frozen within 8 hours of collection. Why is freezing plasma within 8 hours significant for making cryo? Research has shown the amount of liable factors degrades over time prior to freezing. This can be done by thawing in a refrigerator for hours or a few hours in a circulating water bath.

Here we have a FFP pulled from a water bath. Circled are precipitates that are visible prior to centrifugation. They are opaque white in appearance. This is done to concentrate the precipitates to the bottom of the bag. The precipitates will have a thick, white to opaqueish consistency. It can be mistaken as a fibrin clot. After centrifugation, the supernatant is removed by gravity drain or plasma expressor.

Approximately mL of supernatant plasma remains with the cryoprecipitate and is used to re-suspend the precipitates. At this point the cryo may be refrozen immediately or pooled. Pictured on the left is a single cryoprecipitate containing approximately grams of supernatant and the precipitate pellet.

Circled are the precipitated factors. The supernatant plasma, pictured on the right, can be refrozen as a transfusable product called cryo-poor plasma or as a non-injectable product called recovered plasma. Both cryo-poor plasma and recovered plasma are deficient of those cryo factors. Cryo-poor plasma is an injectable product that is typically used for plasma exchange.

Recovered plasma is an unlicensed product that can be shipped to manufactures of plasma products. To create a pool, single cryo are welded onto a pooling harness bag set. The process of welding is sterile and allows the product to be a closed system. The single cryo are pooled to provide a single, combined therapeutically effective blood product, a cryoprecipitate pool.

Pictured is a 5-unit pool. For pooled cryo, the expiration date is determined to be 12 months from earliest date of FFP collection. Thawed single cryo and pooled cryo which are sterilely manufactured have a shelf life of 6 hours. Currently thawed cryo cannot be refrozen or refrigerated, due to regulatory standards.

Fun fact: refrigeration causes the factors to re-precipitate making it unsuitable for transfusion. Each cryo product has to meet regulatory agency requirements. For example, Mayo Clinic Rochester manufactures pools of 5 units, therefore, the QC values we need to pass are greater than or equal to international units per pool of Factor 8 and greater than or equal to mg per pool of fibrinogen.

Patients that benefit from cryoprecipitate are typically patients needing fibrinogen replacement when clinical bleeding has occurred and individuals with disseminated intravascular coagulation DIC. Occasionally, cryo is transfused for inherited disorders of fibrinogen and uremic bleeding. Another indication for cryo is during a massive transfusion, in which it helps maintain hemostasis due to post-partum hemorrhage, and surgical cases such as cardiac, gastrointestinal, transplants, or trauma incidents.

Just like other blood products, it is subject to misuse. Common misuse of cryo is reversal of warfarin therapy, replacement therapy in patients with normal fibrinogen levels, and treatment of bleeding without evidence of fibrinogen deficiency. When choosing cryoprecipitate for transfusion, cryo should be selected as ABO-compatible.

In some instances, large volumes of cryo may cause a positive direct antiglobulin test and mild hemolytic transfusion reactions. This can be caused by the isohemagglutinins, anti-A and anti-B. However, cryo can be administered regardless of Rh. This is due to the fact neither plasma nor cryoprecipitate contain red cells. Compatibility testing is also not required. Transfusion of cryoprecipitate carries the same risks as plasma transfusion. Potential risks and adverse events such as infection- viral or bacterial, volume overload, and transfusion reactions.

Cryoprecipitate has a lower risk of causing hemolytic transfusion reactions than plasma, because of the smaller volume administered. Cryo is administered utilizing aseptic technique, through a filter designed to remove clots and aggregates. Transfusion is started before cryo expires and completed within 4 hours.

External suppliers, such as the American Red Cross, provide blood products to other Mayo campuses. Mayo Clinic Rochester recognized the need to standardize and improve their concentrations to decrease the patient dose. The goal was to drop the adult dose from 10 units to 5 allowing ordering consistency across all Mayo sites. Thank you Jessie. A middle aged man underwent a re-operative aorta surgery.

The patient started to bleed a lot, and like most, their new graft caused depletion of fibrinogen levels significantly. In the end, the patient was transfused 40 units of cryo. That means this patient was exposed to donors! Therefore, if we benchmarked a process improvement, then this patient could have had fewer products, less donor exposure, and less inventory used on one individual.

We experimented 12 different process changes including, but not limited to centrifuge settings, thaw rates, and differing product manipulation. Our group also toured other product manufacturers to see their processes. We re-evaluated multiple steps in the process, starting with implementing new thawing techniques.

Fresh Frozen Plasma varies in volume due to various donor factors, it is important to thaw them evenly. Too slushy or icy of a product is difficult to manipulate.

Fresh Frozen Plasma varies in volume due to various donor factors, it is important to thaw them evenly. Too slushy or icy of a product is difficult to manipulate.

To increase this chance that your products will thaw evenly, the process is now defined to choose FFP that are within 20g of each other. For best recovery, they should be thawed to a slushy or slightly slushy state. Therefore, impacting Factor 8, as it is a temperature sensitive product. We also defined thaw time in the water bath. As a reminder, cryo precipitates are cold insoluble proteins, therefore, it is important to closely monitor thaw. We implemented this by checking the FFP at approximately 1 hour 30 minutes and adding additional time as needed.

The cryoprecipitate is refrozen within 1 hour of thawing and stored at C or colder, and has a shelf life of 12 months. A single unit of cryo typically has a volume between 10 to 15 mL. As a convenience to transfusion services, the majority of the cryo we manufacture is pre-pooled frozen cryo. We pool together 5 single units of cryo with the same ABO type into a single bag of pooled cryo. The volume of pooled cryo generally ranges from 95 — mL.

Due to the development of virus-inactivated Factor VIII concentrates and recombinant factor preparations, cryo is no longer considered first-line therapy for these diseases. Today the most common indication for cryoprecipitate is replacement of fibrinogen in patients with acquired hypofibrinogenemia and bleeding, usually in the setting of surgical bleeding or trauma.

ABO-compatible cryoprecipitate is NOT required due to the small volume of plasma transfused, although this may be important in patients receiving large volumes of cryo relative to their red blood cell mass. Rh compatibility need not be considered when selecting this product for transfusion and cross matching is not necessary.

Leave about mL of supernatant plasma in the bag for resuspending the cryoprecipitate after thawing. Refreeze the cryoprecipitate immediately. Cryoprecipitated AHF can be used: For controlling the bleeding associated with fibrinogen deficiency. To make " Fibrin Glue ", a substance composed of cryoprecipitate and topical thrombin. When combined, they produce an adhesive substance that, applied to a surgical site can reduced bleeding.

It is also know as the " Human Glue " As a second -line therapy for von Willebrand's disease and hemophilia A. Cryoprecipitate should be used only if viral-inactivated Factor VIII concentrates are not available for management of these patients. It expires 1 year from the date the of phlebotomy, not from the date the cryo was prepared. Once cryoprecipitate is thawed, it must be kept at room temperature C. Administration must begin as soon as possible or within 6 hours after thawing.

In test performed on pooled components, the pool shall contain a minimum of mg of fibrinogen and 80 IU of coagulation Factor VIII times the number of components in the pool. Factor XIII. While the method for the creation of Cryo was discovered by Dr.
