This paper presents the principles of functioning of the Military Blood Donation Service and the Military Center for Blood Donation and Hemotherapy in Poland.</p><p><strong>Methods: </strong>The study used data collected in the \"Military Blood Bank\" information processing system and data from annual reports (2010-2021) sent to the Minister of Health of the Republic of Poland. The reports concerned, among others: demographic data on donors, reasons of permanent disqualifications, numbers of complete and incomplete donations, etc.</p><p><strong>Results: </strong>Since 2005, the number of donors registered in military blood donation centers ranged between 15 and 35 thousand/year. The most dramatic declines in donors were observed in 2010 and 2020.

Among the blood donors, men always predominated and the dominant age group (except for 2010) was 25-44 years.

It is specialized in supplying blood and blood products to the Armed Forces. Unfortunately, it was not possible to refer to the functioning of similar institutions in other countries. Therefore, when evaluating the functioning of Polish military blood donation, we had to rely on numerical values (eg, number of donors/year, donor profile, etc.), which prove a very good organization of blood donation centers.

SCD is associated with multiple cerebrovascular complications that threaten neurocognitive function and life. Without screening and preventive management, 11% of children at 24% of adults with SCD have ischemic or hemorrhagic strokes. Stroke screening in children with SCD is well-established using transcranial Doppler ultrasound (TCD). TCD velocities above 200 cm/s significantly increase the risk of stroke, which can be prevented using chronic red blood cell (RBC) transfusion. RBC transfusion is also the cornerstone of acute stroke management and secondary stroke prevention. Chronic transfusion requires long-term management of complications like iron overload. Hydroxyurea can replace chronic transfusions for primary stroke prevention in a select group of patients or in populations where chronic transfusions are not feasible. Silent cerebral infarction (SCI) is even more common than stroke, affecting 39% of children and more than 50% of adults with SCD; management of SCI is individualized and includes careful neurocognitive evaluation. Hematopoietic stem cell transplant prevents cerebrovascular complications, despite the short- and long-term risks.
