ABSTRACT
Objective To provide reference for the cold chain of stored RBCs on the sea by evaluating both blood containers containing phase-changed materials and the quality of stored RBCs during transportation.Methods In order to simulate blood supply on the sea,we transported the stored RBCs on land(100 min),on the sea(45 h)and stored them on the sea for another 7 days.The free hemoglobin(Hb), lactate dehydrogenase(LDH), and concentrations of K +and Na+were measured.Results The temperature of the blood container containing phase-changed materials rose from 4.1℃to 9.5℃.The contents of free Hb,K+and LDH were increased to(0.083 ±0.032)g/L,(15.097 ±1.791)mmol/L, and(106.00 ±17.83)U/L,respectively.During blood storage,the contents of the above three indices were increased to (0.111 ±0.035)g/L,(27.238 ±3.509)mmol/L and(227.00 ±111.94)U/L, while Na +decreased to(113.63 ± 4.012)mmol/L.Conclusion The temperature of the blood container containing phase-changed materials can be maintained at a constant temperature under more complicated environmental conditions,and the quality of the stored RBCs can be ensured.RBCs stored on the sea for more than 7 days are damaged more seriously than those stored on land.
