For what reason is Louise's transfusion prescription deemed unnecessary?

The transfusion prescription for Louise is considered unnecessary because she does not show symptoms of anaemia. The decision to administer a blood transfusion typically hinges on the patient's clinical status and the presence of symptoms associated with low hemoglobin levels. Symptoms of anaemia may include fatigue, weakness, shortness of breath, and pallor, among others. If a patient is not exhibiting these symptoms despite potentially low hemoglobin levels, the rationale for a transfusion is weakened, as the primary goal of transfusion is to alleviate those symptoms or address significant blood loss.

In context, having a hemoglobin level above a certain threshold, such as 100 g/L, might also support the conclusion that transfusion is not required, but the absence of symptoms is a more direct influencer in determining the need for a transfusion. Experiences of significant blood loss or dehydration could prompt more immediate transfusion needs, but in this case, the lack of anaemic symptoms directly influences the decision-making process regarding the transfusion.
