Blood transfusion thresholds chart covering restrictive PRBC triggers, platelet goals, FFP dosing, and cryoprecipitate fibrinogen thresholds for anesthesia review.
Review the core table first, then launch practice to convert recognition into faster recall.
| Product | Indication | Trigger / threshold | Dose |
|---|---|---|---|
| Packed red blood cells | Oxygen-carrying support in anemia or blood loss | Restrictive threshold often 7 g/dL in stable adults; 8 g/dL is commonly used in selected orthopedic or cardiovascular-risk patients | 1 unit typically raises hemoglobin by about 1 g/dL |
| Platelets | Thrombocytopenia with bleeding risk or procedures | <10,000/µL prophylactically in stable nonbleeding patients; <50,000/µL for most invasive procedures or active bleeding; <100,000/µL for neurosurgery / posterior eye surgery | 1 apheresis unit often raises platelet count by about 30,000-50,000/µL |
| Fresh frozen plasma | Multiple-factor deficiency with bleeding or urgent procedure | Clinically significant coagulopathy, often INR >1.5 when bleeding or performing an urgent invasive procedure | 10-15 mL/kg |
| Cryoprecipitate | Hypofibrinogenemia or dysfibrinogenemia | Fibrinogen often <100 mg/dL in ongoing bleeding; many major-hemorrhage protocols try to keep fibrinogen at least >150 mg/dL and sometimes closer to 200 mg/dL | 10-unit pool commonly raises fibrinogen by about 50-100 mg/dL |
| 4-factor PCC | Urgent warfarin reversal with major bleeding | Severe vitamin K antagonist-associated coagulopathy | Weight / INR-based dosing plus vitamin K |
