(2) Most trials of oxygen carriers have focused on their use in surgery, primarily as a way to minimize the need for allogeneic blood transfusion. (3) The benefits of these products in comparison with other blood conservation technologies and with allogeneic blood transfusion must be determined. (4) The safety and cost-effectiveness of these products, and the patient populations that would benefit most from their use require further study. |
