title: Application status of blood constituents during massive blood transfusion in some regions of China.
abstract: OBJECTIVE
  This study aims to learn about the current situation of surgical massive blood transfusion in China's Class III general hospitals, which could provide the basis for the formulation of guidelines on massive blood transfusion.
  
  
  METHODS
  A multicenter retrospective research on the application status of blood constituents during massive blood transfusion was conducted and a comparative analysis on the distribution of the population infused with other blood constituents and the transfusion volume at different periods of time when red blood cells are infused in different units within 24 hours as well as on the blood applied for both the death group and survival group was made in this study.
  
  
  RESULTS
  In China, during massive blood transfusion the ratio of the dosage of fresh frozen plasma to the dosage of red blood cell suspension reached 1:1-2, while the dosage of platelet and cryocepitate appeared to be very small.
  
  
  CONCLUSIONS
  During massive blood transfusion, clinicians in 20 Chinese hospitals paid more attention to the infusion of fresh frozen plasma while making the infusion of red blood cells. However, they paid little attention to the supplement of platelet and cryocepitate.
