Background
Transfusion Risk Ratios[1]
| Rate | Complication |
| 1:10 | Febrile non-hemolytic transfusion reaction per pool of 5 donor units of platelets (1 pack) |
| 1:100 | Minor allergic reactions (urticaria) |
| 1:300 | Febrile non-hemolytic transfusion reaction per unit of RBC (1 pack) |
| 1:700 | Transfusion-associated circulatory overload per transfusion episode |
| 1:5,000 | Transfusion-related acute lung injury (TRALI) |
| 1:7,000 | Delayed hemolytic transfusion reaction |
| 1:10,000 | Symptomatic bacterial sepsis per pool of 5 donor units of platelets |
| 1:40,000 | Death from bacterial sepsis per pool of 5 donor units of platelets |
| 1:40,000 | ABO-incompatible transfusion per RBC transfusion episode |
| 1:40,000 | Serious allergic reaction per unit of component |
| 1:82,000 | Transmission of hepatitis B virus per unit of component |
| 1:100,000 | Symptomatic bacterial sepsis per unit of RBC |
| 1:500,000 | Death from bacterial sepsis per unit of RBC |
| 1:1,000,000 | Transmission of West Nile Virus |
| 1:3,000,000 | Transmission of HTLV per unit of component |
| 1:3,100,000 | Transmission of hepatitis C virus per unit of component |
| 1:4,700,000 | Transmission of HIV per unit of component |
- Fluid Overload
- Split pRBCs to tranfuse more slowly (as slow as 1mL/kg/hr)
- Sepsis
- Most commonly due to yersinia which is able to grow easily in refrigerated blood

Diagnosis
| TRALI | TACO | |
| Onset | Acute, within 6hrs | Often more gradual |
| BP | Low | High |
| Temp | Febrile | Normal |
| JVD/pedal edema | Unlikely | Likely |
| CVP/PAWP | Normal | Elevated |
| BNP | Normal | Elevated |
| Resp | Dyspneic | Dyspneic |
| CXR | B/l infiltrates | B/l infiltrates |
Management
- For all reactions:
- Stop the transfusion (at least temporarily)
- Call the blood bank
- Draw a new type + screen
