Abstract: Objective To understand the current situation of clinical blood transfusion in hospitals,and to improve the level of clinical scientific,rational and safe use of blood. Methods We performed retrospective statistical analysis of a large number of blood transfusion in past 3 years through accessing to medical records,in accordance with the relevant standards for clinical blood use. Results A total of 138 cases of massive transfusion,all of 138 cases received transfusion of red blood cells,the total infusion volume of 1853.0U,an average of 13.4 U/case;132 cases received fresh frozen plasma,the total infusion volume of 15 6940.0 mL,with an average of 1 137.2 ml/case; 82 cases of infusion of cold precipitation,the total infusion volume of 1 202.8 U,the average 8.7 U/case; 50 cases were treated with single platelet transfusion,total infusion volume of 70 treatments,the average of 0.5 treatment/case. The massive transfusion happened in 12 departments,the top 3 were cardiovascular surgery accounted for 42.04%,department of hepatobiliary surgery accounted for 13.05%,obstetrics accounted for 12.33%. By disease classification,the first few were aortic dissection,liver and spleen rupture,placenta previa,coronary heart disease,gastrointestinal bleeding,tumor etc. The number of patients with abnormal coagulation before operation accounted for 65.9% of the total,anemia accounted for 38.4% of the total. Death occurred in 36 cases,the mortality was 26.1%,The higher mortality is Department of Gastroenterology,Abdominal Tumor Surgery,Neurosurgery,ICU,Cardiovascular Surgery. Conclusion Use of massive blood transfusion exist some problem in most departments,such as performance in the composition of the rational use of improper proportion,the use of cold precipitation and platelet is not timely and enough,the rational ratio of plasma and cold precipitation was rather low when the mixed blood was transfused; There are empirical,habitual use of blood phenomenon;Perioperative anemia and coagulation abnormalities have not been corrected in time; Use plasma to supplement blood volume.
