Highlights: [•] Organic compounds affect the hygroscopicity properties of atmospheric aerosols. [•] Glycerol suppress nucleation of the mixed Na2SO4/glycerol droplets. [•] The efflorescence of aerosols promotes the transformation of glycerol from γγ to αα. [•] Glycerol suppresses the formation of CIPs between Na+ and SO4 2− in mixed droplets.

Objective: This study aims to learn about the current situation of surgical massive blood transfusion of different surgical departments in China's Tertiary hospitals, which could provide the basis for the formulation of guidelines on massive blood transfusion., Method: A multicenter retrospective research on the application status of blood constituents during massive blood transfusion was conducted and a comparative analyses of survival and length of hospitalization in patients from different departments (trauma, cardiac surgery, obstetric conditions, or other common surgeries), were performed., Result: 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 cryoprecipitate appeared to be very small. The risk of in-hospital death were associated with the primary disease in patients receiving massive blood transfusion (Log-Rank P = 0.000), cardiac surgery and trauma patients who received massive blood transfusion have a higher risk of death rate., Conclusions: Patients undergoing massive blood transfusion among different surgical departments have a certain difference in use of blood transfusion, mortality rate and the time of death. Our findings suggested that we should set up an independent transfusion program in cardiac surgery and trauma patients of massive blood transfusion.

Objective: The aim of this study was to learn the current situation of surgical massive transfusion of death and survival groups in China, which could provide the basis for the formulation of guidelines on massive transfusion., Methods: A multicenter retrospective research for the application status of blood constituents during massive blood transfusion was conducted, the differences of fresh frozen plasma and platelet application between death group and survival group were compared, and the transfusion volume and the distribution of other blood constituents were analyses at different periods of time when red blood cells are infused between death group and survival group., Results: The patients with fresh frozen plasma compare the patients with red blood cell was 1:1-2 during massive transfusion, while the dosage of platelet and cryocepitate were transfused very small. Results showed that the average amount of platelet and plasma in death group was significantly lower than those in survival group., Conclusion: During massive 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. The average quantity of plasma and platelet in survival group were also higher than those in death group.
