Blood transfusion in gynecology is often required in the following scenarios: - Severe Hemorrhage: Conditions such as postpartum hemorrhage, which can occur after childbirth, may necessitate a blood transfusion to replace lost blood. - Anemia: Women with severe anemia due to heavy menstrual bleeding or other gynecological conditions may require a transfusion to restore healthy hemoglobin levels. - Surgical Procedures: Major surgeries like hysterectomy or myomectomy often carry the risk of significant blood loss, making transfusions necessary.
