A controversial artificial blood study is almost complete, but local hospitals have not had any participants.
No one has participated in experimental trials using the blood substitute polyheme at either University Hospital or LDS Medical Center.
Dr. Stephen Morris, who's in charge of the study at the U, says it's not that anyone has refused, they just haven't had anyone qualify.
Dr. Stephen Morris: "People who are injured and in danger of dying from a loss of blood coming to the hospital, they would potentially be candidates to receive this blood substitute, Polyheme."
Dr. Morris says potential patients who are not wearing a wristband refusing consent to the study, still only have a 50-50 chance of getting either Polyheme or Saline.
