Summary
Enter patient weight, current fibrinogen, and target fibrinogen to calculate the number of cryoprecipitate units needed.
How it works
- Enter the patient's weight in kilograms or pounds.
- Enter the current (measured) plasma fibrinogen in mg/dL.
- Enter the desired target fibrinogen in mg/dL.
- The calculator estimates plasma volume as weight (kg) × 45 mL/kg.
- Units = (Target − Current) × Plasma Volume (dL) ÷ 250 mg/unit.
- The result is rounded up to the nearest whole unit.
Use cases
- Estimating cryoprecipitate dose in disseminated intravascular coagulation (DIC).
- Fibrinogen replacement in massive transfusion protocols.
- Pre-operative correction of hypofibrinogenemia before surgery.
- Obstetric hemorrhage management when fibrinogen falls critically low.
- Trauma resuscitation requiring coagulation factor replacement.
- Clinical pharmacology education on blood product dosing.
