Abstract
Peripheral blood progenitor cells (PBPC) are increasingly used as a source of stem cells for either autologous or allogeneic hematopoietic transplantation in children. Although technically similar to adult procedures, apheresis in small children worries some operators and physicians that have little experience in managing pediatric patients or donors. However several published series have showed that these procedures, when performed by experienced teams are safe and can obtain enough amount of PBPC for either autologous or allogeneic hematopoietic transplantation. Some technical aspects must be considered in pediatric apheresis due to the size of the patient/donor. Factors that must be evaluated are extracorporeal circuit volume, blood flow rates, type of anticoagulant and vascular access. Other important issue to be considered is the emotional stress for them and their relatives. Leukaphereses in children may be performed with any of the reported continuous blood cell separator without sedation. Adverse events are mainly related either to vascular access or to metabolic or hemodynamic changes. Anyway, taking all these complications together, they are not higher than those adverse events or toxicities reported after general anesthesia and bone marrow harvesting.
