Abstract: ObjectiveTo evaluate the feasibility of suspended RBC transported by pneumatic tube system(PTS). For blood products, especially the red blood cells, being transported fast and arrived safely provide reference for clinical departments. MethodsFirst, we transported 77 bags of suspended RBC within 5 to 10 days by using PTS, and then detected changes of free hemoglobin (FHb) content, electrolyte and temperature before and after transportation. We record the time consuming by the transportation at the same time for the test. ResultsThe suspended RBC within 5 to 10 days transporting by PTS did not lead to any significant differences for the test results of FHb content, electrolyte and temperature before and after transportation (P>0.05). And the time of transporting blood by PTS is obviously less than drawing by people. ConclusionThe transport of suspended RBC by PTS is theoretically possible. The PTS can guarantee the safety of blood transportation. More samples are in need for the experimental research in order to provide a more detailed data support.
