ABSTRACT

Objective To explore the influence on and changes in the biochemical indices of red blood cells(RBCs)in additive solution leukocytes reduced preserved in navy ship force on a long voyage.Methods According to the Requirement of Health Examination for Blood Donors(GB 18467 -2011),RBCs in additive solution leukocytes reduced were prepared from 10 healthy voluntary blood donators one day before sailing.Each blood sample was divided into two parts,one in test group and another in control group.All the groups had samples taken for the biochemical index detection after 1,3,5,7,14 and 21 days of sailing respectively.Results ①The change in total protein(P=0.235)and albumin (P=0.119)concentration was not obvious,and the difference between the two groups was not significant.②The change in total creatinine(P=0.001)and uric acid(P=0.001)concentration was obvious, but the difference between the two groups was not significant.③The change in total cholesterol(P=0.354)concentration was not obvious,but the change in triglycerides(P=0.005)concentration was significant.The difference between the two groups was not significant.④The concentration of lactate dehydrogenase, hydroxybutyrate dehydrogenase and creatine kinase increased with the time of preservation(P<0.001).The difference between the two groups was not significant.⑤The interaction between grouping effect and time effect had no significant influence on the concentration of osmolarity(OSM)(P=0.968)and glucose(Glu) (P=0.406).Between the two groups,the difference of concentrations of OSM(P=0.569)and Glu(P=0.115)was not significant.Conclusion Under the 4 class sea conditions, a long voyage has some impact on the storage of RBCs in additive solution leukocytes reduced,as in the conventional blood storage refrigerator(4 ±2)℃.The results of this study have important clinical implications for our further study of marine blood support.
