简要总结
By doing this study, researchers hope to learn the following:
- If providing hyperbaric oxygen (HBO) therapy prior to an umbilical cord blood (UBC) transplant will help to improve the homing process
- The safety of HBO administration in the setting of the UBC transplant
- The effects of HBO therapy on the engraftment process
详细描述
Research has suggested that high levels of erythropoietin (EPO) decreases the ability of infused umbilical cord stem cells to home to the bone marrow. The investigators will investigate the use of hyperbaric oxygen (HBO) therapy to decrease the plasma concentrations of EPO prior to UBC transplant and evaluate the resulting impact on UBC homing.

研究组 & 干预措施
Hyperbaric Oxygen Treatment
Administration of hyperbaric oxygen the morning of UCB transplant.
干预措施: Administration of hyperbaric oxygen (Device)
结局指标
主要结局
Safety of HBO Administration in the Setting of UCB Stem Cell Transplantation
时间窗: Toxicity assessment with 24hrs of treatment
Treatment limiting toxicities are defined as the occurrence of any of the following complications within 24hrs of treatment: pneumothorax, death, irreversible grade III or any grade IV toxicity that is determined by the treating physician to be related to HBO therapy.
次要结局
- Determine the Effects of HBO Therapy on Neutrophil Count Recovery.(Daily measurement of neutrophil counts up to 90 days post transplant.)
- Proportion of Reduced Intensity Conditioning Participants With Complete Engraftment.(28 days)
