What hemoglobin level is used as the threshold to guide ongoing transfusion therapy?

• A. >7 g/dL
• B. >9 g/dL
• C. >11 g/dL
• D. >13 g/dL

Answer: (A)

The main idea here is using a restrictive transfusion approach: for most stable patients, you transfuse to keep hemoglobin around 7 g/dL. This threshold is chosen because lowering transfusions reduces exposure to risks without compromising outcomes in many people. So, the ongoing transfusion therapy is guided by aiming to maintain hemoglobin just above about 7 g/dL. In patients with significant cardiovascular disease or ongoing major bleeding, clinicians may target a higher level (often around 8 g/dL), but in typical stable obstetric scenarios, 7 g/dL is the standard threshold. Values like 9, 11, or 13 g/dL would lead to more liberal transfusion and are not routinely used as the standard trigger.
