[Protective environment strategies for hematopoietic stem cell transplantation: progress and prospects]

With the progress of hematopoietic stem cell transplantation technology, the reduction of pretreatment intensity, the shortening of bone marrow suppression time and the reduction of infection risk, especially the physical and psychological stress for doctors and patients caused by rigorous protection procedures, the protective environment strategies need improvement. It has been found that, regardless of whether total environment protection is implemented, there is no significant difference in the outcomes of chemotherapy patients with neutropenia. Therefore, the traditional protective environment strategies are being improved. The protective environment strategies for hematopoietic stem cell transplantation patients have developed rapidly in the past two decades, from the replacement of laminar flow equipment by high-efficiency filtration devices to the development of home care after transplantation. In this article, the progress in protective environment strategies for hematopoietic stem cell transplantation patients is reviewed and further reflect, providing reference for future improvement.
