Cryoprecipitate Transfusion Guidelines
Last update: March 20, 2020
Standard transfusion thresholds
- Fibrinogen < 100-150 mg/dL
- A severely low fibrinogen can prolong the PT/INR, and giving cryo in these cases can largely correct it. This is especially common in cirrhotic patients, so please remember to check fibrinogen level along with daily PT/PTT testing in appropriate patients
- Pregnant women have higher fibrinogen levels, and cryoprecipitate transfusion may be indicated at higher levels, such as < 200 mg/dL
- TEG alpha or K-time below laboratory normal value
Emergency critical shortage transfusion thresholds
- During critical times of blood product shortage, the cryo transfusion threshold will be lowered.
- Every cryo unit ordered may be triaged by transfusion medicine
- A smaller dose of cryo may need to be given (ie, 5 bags instead of the usual 10 bag dose).
- Cryo transfusions may be limited to only patients with life-threatening bleeding if necessary, to preserve a limited cryoprecipitate inventory.
