You Made the Call We asked, and you answered! Here are a few responses from this month’s “You Make the Call.” For the full description of the clinical dilemma, and to see how the expert responded, turn to page 53. Clinical Dilemma: A 33-year-old woman with sickle cell disease is planning to undergo bariatric surgery with a Roux-en-Y procedure. How should transfusion be managed through this surgery? Should she have exchange transfusion prior to surgery? I would propose to transfuse the patient with two to three units of RBC concentrates at about weekly intervals, starting 4 weeks before the planned surgical intervention. This will suppress her own production of erythrocytes, and she will have enough HbA before surgery.
