title: [Effects of Two Placement Ways for Storage of Blood Bag on Biochemical Indexes of Leukodepleted Red Blood Cells].
abstract: OBJECTIVE
  To investigate the effects of 2 different ways of storage bag placement on some biochemical indexes of leukodepleted red blood cells (LD-RBC) to as to ensure the efficacy and safety of clinical blood transfusion.
  
  
  METHODS
  The whole blood samples of 20 donors (400 ml/donor) were selected for preparating the LP-RBC, which were divided evenly into 10 bags. The 10 bags were randomly divided into 2 groups; the bags in 1 group were placed uprightly, while the bags in another group were placed horizontally. The bags of 2 groups were stored in the same conditions. One storage bag from each group was taken randomly on day 7, 14, 21, 28, 35 respectively, and then the biochemical indexes of samples were detected and analyzed.
  
  
  RESULTS
  The values of K(+) and LAC on day 14, the value of LDH on day 28 in the uprightly placed group were higher than those in the horizontally placed group (P < 0.05), the value of Na(+) on day 28, and the value of Glu on day 35 in the uprightly placed group were lower than those in horizontally placed group (P < 0.05), but there was no significant difference in Cl(-) level between 2 groups (P > 0.05).
  
  
  CONCLUSIONS
  The storage bags placed by different ways during the storage show different influence on some biochemical indexes of LD-RBC in the storage period.
