What are the indicators for transfusion of PRBCs?

• A. Hgb 10 Hct 30
• B. Hgb 8 Hct 25
• C. Hgb 7 Hct 22
• D. Hgb 6 Hct 20

Answer: (B)

The selection of hemoglobin (Hgb) and hematocrit (Hct) levels for indicating the need for transfusion of packed red blood cells (PRBCs) is guided by the patient's clinical status rather than strict laboratory values alone. The choice reflecting hemoglobin of 8 g/dL and hematocrit of 25% presents a threshold commonly recognized in transfusion guidelines, especially for stable patients without significant cardiovascular disease. At this level, patients may begin to exhibit symptoms of anaemia, and transfusion may become necessary to improve oxygen delivery and prevent complications. While each patient's situation can differ, these values serve as a general reference point in terms of when to consider transfusion. In clinical practice, lower thresholds may be considered for transfusion in patients with underlying conditions such as coronary artery disease or significant comorbidities, while more stable patients might tolerate lower hemoglobin levels without immediate transfusion. Thus, B represents criteria that align with typical transfusion practices for patients who are symptomatic and require improvement in oxygen-carrying capacity.
