What is the primary treatment for severe anemia due to subgaleal hemorrhage?

Severe anemia resulting from subgaleal hemorrhage often necessitates blood transfusions as a primary treatment. This is because the condition leads to a significant loss of blood volume and red blood cells, which can have critical implications for oxygen delivery to vital organs. A blood transfusion directly addresses the anemia by replenishing the lost red blood cells and restoring the patient's hemoglobin levels, thereby stabilizing their condition.

While antibiotics, surgery, and fluid replacement may play roles in managing complications or promoting recovery in certain contexts, they do not directly correct the anemia caused by the hemorrhage. Antibiotics might be indicated if there are signs of an infection, surgery could be necessary for other complications arising from the hemorrhage, and fluid replacement may be considered to manage volume status, but none of these options specifically target the need for increased red blood cell count and hemoglobin restoration as effectively as a blood transfusion does. Thus, blood transfusions are the most appropriate and immediate treatment for severe anemia in this scenario.
