General
- Type: Blood products
- Dosage Forms:
- Common Trade Names:
Indications
- Rapid reversal of warfarin anticoagulation (in setting of bleeding or need for invasive procedure)
- Bleeding and multiple coagulation defects (e.g. DIC with significant PT/PTT elevation)
- Correction of coagulation defects for which no specific factor is available
- Transfusion of more than one blood volume with evidence of active bleeding + coagulopathy
Adult Dosing
- 1 bag = 1 unit = 250 mL
- 10-20 mL/kg (4-6 units in 70kg adult) will increase factors by ~20-30%
- Transfuse at least 15 mL/kg at a time (4 units in 70-kg adult)
- Must be thawed in 37 degree Celsius water bath for about 45 minutes prior to administration[1]
Pediatric Dosing
- Neonates/small children: 10-20 mL/kg will increase factor levels by 15-25%
Special Populations
- Pregnancy Rating: C
- Lactation:
- Renal Dosing:
- Hepatic Dosing:
Contraindications
- Allergy to class/drug
- ABO incompatibility
Adverse Reactions
Serious
- Hemolytic transfusion reactions
- Febrile non-hemolytic reactions
- Transfusion-associated circulatory overload (TACO)
- Transfusion-related acute lung injury (TRALI)
- Transfusion-associated graft-versus-host disease
- Anaphylaxis
- Sepsis
Common
- Headache, paresthesia
- Nausea
- Pruritus, urticaria
Pharmacology
- Half-life:
- Metabolism:
- Excretion:
- Mechanism of Action:
Comments
- Contains all coagulation factors and fibrinogen
- 40 mL/kg raises any factor by 100% (each unit is ~200mL)
- May cause fluid overload
- ABO compatibilty a must but crossmatch before transfusing not
- INR of FFP is ~1.6; therefore transfusing for INR <1.7 is not advised[2]
- Retains active coagulation factors for up to 5 days after being thawed
